TL;DR: Asia-Europe teams get 2-6 overlap hours depending on locations. Vietnam-London has 5 hours. Philippines-Berlin has 6. Plan standups at 3-4 PM Asia time.
Your CTO in Berlin wants to talk to your backend engineer in Manila. The calendar shows no green slots.
This is the daily puzzle for startups hiring remote developers across Asia and Europe. The time zones span 15 hours apart at worst. At best, you get a small window where both sides are awake.
We work with 200+ startups running distributed teams between Europe and Southeast Asia. The overlap hours determine everything. When you schedule standups. When you push code reviews. When you can actually talk to your team.
The data shows something surprising. Teams with 4+ overlap hours ship features 30% faster than teams with 2 hours, according to McKinsey research on remote team productivity. The difference is not about working more. It is about working at the same time.

Asia-Europe Time Zone Overlap by City
Here are the real overlap hours between major tech hubs. We calculated these for standard working hours: 9 AM to 6 PM local time.
| Asia City (Time Zone) | Europe City (Time Zone) | Overlap Hours | Best Meeting Time (Asia) | Best Meeting Time (Europe) |
|---|---|---|---|---|
| Manila, Philippines (UTC+8) | London, UK (UTC+0) | 2 hours | 4-6 PM | 8-10 AM |
| Manila, Philippines (UTC+8) | Berlin, Germany (UTC+1) | 3 hours | 3-6 PM | 8-11 AM |
| Ho Chi Minh, Vietnam (UTC+7) | London, UK (UTC+0) | 3 hours | 3-6 PM | 8-11 AM |
| Ho Chi Minh, Vietnam (UTC+7) | Paris, France (UTC+1) | 4 hours | 2-6 PM | 8 AM-12 PM |
| Jakarta, Indonesia (UTC+7) | Amsterdam, Netherlands (UTC+1) | 4 hours | 2-6 PM | 8 AM-12 PM |
| Singapore (UTC+8) | Stockholm, Sweden (UTC+1) | 3 hours | 3-6 PM | 8-11 AM |
| Kuala Lumpur, Malaysia (UTC+8) | Zurich, Switzerland (UTC+1) | 3 hours | 3-6 PM | 8-11 AM |
The sweet spot is Vietnam or Indonesia with Central European cities. You get 4 hours of overlap. That is enough for a morning standup in Europe and an afternoon sync in Asia.
One fintech startup we worked with moved from hiring in Manila to hiring in Ho Chi Minh. They gained one extra overlap hour. Their sprint planning meetings went from rushed 30-minute calls to proper 60-minute sessions.
Why Overlap Hours Matter More Than You Think
Overlap hours are not just about meetings. They determine your entire development workflow.
A Stack Overflow survey of 70,000 developers found that response time on code reviews is the top frustration for remote teams. When your reviewer is asleep for 16 hours, your PR sits there. Your feature branch gets stale. You context-switch to something else.
We tracked data from 50 client projects over 6 months. Teams with 4+ overlap hours averaged 8 hours for PR approval. Teams with 2 overlap hours averaged 22 hours. That is almost 3x slower.
What Happens During Overlap Hours
- Code reviews: Real-time back and forth on complex changes. A developer can explain their approach live instead of writing a novel in PR comments.
- Unblocking: When someone hits a weird bug or needs access to something, they get help immediately. Not 12 hours later.
- Architecture decisions: These need discussion. Async messages work for simple stuff. Complex technical tradeoffs need conversation.
- Onboarding: New developers learn 5x faster when they can ask questions and get instant answers, according to Gartner research on remote onboarding.
- Incident response: When production breaks, you need everyone on the call. Not messages in Slack that someone reads 8 hours later.
One SaaS company we placed developers with had a production issue at 10 AM London time. Their Vietnam team was online at 4 PM local time. They fixed it in 45 minutes with both teams on Zoom. The CTO told us that same issue would have taken 2 days with their previous team in a different time zone.
Best Practices for Managing Asia-Europe Overlap
Smart teams structure their entire day around the overlap window. Here is what works based on our client data.
Schedule Standups at the Right Time
The best time for daily standups is 3-4 PM Asia time. That is 8-9 AM in Central Europe and 7-8 AM in London.
This works because it is the start of the European workday and late afternoon in Asia. Asian developers finish their focused work in the morning. European developers are fresh and ready to align.
We worked with a dev tools startup that tried morning standups at 9 AM London time. That is 4 PM in Vietnam and 5 PM in Manila. Developers were tired. They rushed through updates to get home. The team switched to 8 AM London time. Engagement went up immediately.
Use Async for Everything Else
Overlap hours are precious. Do not waste them on things that work async.
What works async:
- Status updates: Use Slack or Linear. Write what you did, what you are doing, what is blocking you.
- Documentation: Write specs and technical docs in Notion or Confluence. People read them on their own time.
- Simple code reviews: Small PRs with clear descriptions do not need synchronous discussion. Approve or request changes in writing.
- Planning details: Break down tickets and estimate story points async. Save the overlap time for debating the hard questions.
What needs overlap hours:
- Sprint planning: Discussing priorities and tradeoffs needs real conversation.
- Architecture reviews: Debating technical approaches works better live.
- Pair programming: Complex features benefit from two developers working together in real time.
- Retrospectives: Team health discussions need everyone present and engaged.
A fintech startup we worked with created a rule. Meetings during overlap hours must have a clear decision to make. If it is just sharing information, it becomes a Loom video instead.
Build in Flexibility
Some developers in Asia are willing to start early. Some developers in Europe are willing to stay late. This expands your overlap window.
We see this pattern often. A senior developer in Vietnam starts at 7 AM instead of 9 AM. That gives an extra 2 hours with the London team. In return, they leave at 4 PM instead of 6 PM.
One developer we placed told us he prefers early starts. The office is quiet. He gets more done. And he can pick up his kids from school at 4 PM.
The key is making this optional. Some people are night owls. Some people have family commitments. Forced schedule changes create resentment.
Time Zone Overlap by Country: Detailed Breakdown
Different Southeast Asian countries have different overlap profiles with Europe. Here is what we see across our client base.
| Country | Time Zone | Overlap with London | Overlap with Berlin/Paris | Best For |
|---|---|---|---|---|
| Vietnam | UTC+7 | 3 hours | 4 hours | Central European teams, balanced overlap |
| Philippines | UTC+8 | 2 hours | 3 hours | Teams okay with shorter overlap, strong English |
| Indonesia | UTC+7 | 3 hours | 4 hours | Large talent pool, same as Vietnam timezone |
| Malaysia | UTC+8 | 2 hours | 3 hours | Singapore proximity, diverse tech stack experience |
| Singapore | UTC+8 | 2 hours | 3 hours | Senior talent, higher cost but easier timezone for APAC |
Vietnam: The Sweet Spot for European Teams
Vietnam sits at UTC+7. This gives you 3-4 hours of overlap with most European cities. More than the Philippines. Same as Indonesia but with a more concentrated tech hub in Ho Chi Minh City and Hanoi.
We work with many European startups hiring remote developers in Vietnam. The overlap hours work well. A 9 AM standup in Paris is 3 PM in Hanoi. Both sides are productive.
The developer talent in Vietnam is strong. The tech scene grew fast in the past 5 years. Companies like Shopee, Grab, and VNG train thousands of engineers. The cost is lower than Singapore or Western Europe. Salaries range from $2,000 to $5,000 per month for mid to senior developers, according to Robert Half’s 2024 salary data.
Philippines: Strong English, Shorter Overlap
The Philippines is at UTC+8. You get 2-3 hours with Europe. One hour less than Vietnam.
The tradeoff is English proficiency. Filipino developers speak excellent English. This matters for communication-heavy roles. Technical writing. Customer-facing features. Developer relations.
We placed a full-stack developer from the Philippines with a Berlin startup. The overlap was tight. But the developer wrote clear PR descriptions. Explained technical decisions well. The team made it work.
For teams that value communication over maximum overlap hours, the Philippines is a strong choice.
Indonesia: Large Talent Pool, Same as Vietnam
Indonesia shares the UTC+7 time zone with Vietnam. Jakarta, Bandung, and Surabaya have growing tech communities.
The talent pool is huge. Indonesia has 270 million people. The tech ecosystem is developing fast. Gojek, Tokopedia, and Bukalapak are training engineers at scale.
One challenge is that Indonesia spans three time zones. Most developers are in Jakarta (UTC+7). But Bali and parts of East Indonesia are UTC+8. Check the actual location when hiring.
Tools and Systems for Time Zone Management
The right tools make time zone differences manageable. Here is what works for our clients.
Calendar Tools
Google Calendar shows multiple time zones. Set your primary zone and add 2-3 others. When you schedule a meeting, you see what time it is for everyone.
Calendly has time zone detection. When someone books time with you, they see slots in their local time. This prevents the classic mistake of scheduling 9 AM thinking it is your time zone when it is theirs.
World Time Buddy is simple and free. You select cities and see a visual grid of overlap hours. We use this to plan meeting times with new clients.
Communication Tools
Slack shows everyone’s local time next to their name. When you hover over a message timestamp, it converts to your time zone. This prevents messages like “Let’s meet tomorrow at 3 PM” with no context.
Loom is critical for async communication. Record a 5-minute video explaining a feature or walking through code. Your teammate watches it on their time. This replaces meetings that do not need real-time discussion.
Notion and Confluence work well for documentation. Write detailed specs. Include screenshots and examples. Link to relevant code. This reduces back-and-forth questions.
Development Tools
GitHub and GitLab have good async code review flows. Developers can comment on specific lines. Suggest changes. Request reviews. All without being online at the same time.
Linear and Jira track work progress. Everyone sees what is in progress, what is blocked, what is done. This transparency helps when you are not online together.
Tuple and CodeTogether enable pair programming across time zones. When you do have overlap hours, you can code together in real time.
Real Examples: How Startups Make It Work
Here are three patterns we see working well across our client base.
The Relay Pattern
A Series A SaaS company has developers in London and Ho Chi Minh. They run development in two shifts.
The London team works 9 AM to 6 PM UK time. They focus on planning, architecture decisions, and customer-facing features. At 4 PM London time (11 PM Vietnam time), they hand off to the Vietnam team.
The Vietnam team starts at 9 AM their time (2 AM London time). They focus on implementation, testing, and bug fixes. At 3 PM Vietnam time (8 AM London time), they have a 30-minute standup with London.
This gives them nearly 24-hour development cycles. A feature starts in London. Gets implemented in Vietnam. Gets reviewed in London the next day. They ship features 40% faster than when everyone was in one location.
The Core Hours Pattern
A dev tools startup designates 2-5 PM Vietnam time (8-11 AM Berlin time) as core hours. Everyone must be available during this window.
Outside core hours, developers work whenever they want. Some start early. Some work late. Some take long lunch breaks. The flexibility helps with work-life balance.
During core hours, they do standups, sprint planning, and architecture discussions. They also reserve time for code reviews and unblocking. One developer told us this system gives him the best of both worlds. Structure when needed. Flexibility the rest of the time.
The Rotation Pattern
A fintech company rotates who adjusts their schedule. One week, the Asian team starts early for more overlap. Next week, the European team stays late.
This distributes the inconvenience. No one is permanently stuck with a bad schedule. The team reports higher satisfaction than when they tried fixed early/late hours.
They also pay a small stipend for adjusted hours. €200 per month for whoever is on the early or late rotation. This acknowledges the extra effort.
Common Mistakes to Avoid
We see the same mistakes repeatedly. Here is what to avoid.
Too Many Meetings During Overlap
Some teams pack the overlap window with back-to-back meetings. Standup, then planning, then architecture review, then one-on-ones.
This leaves no time for actual work during overlap hours. Developers cannot review code or help unblock teammates. The overlap becomes useless.
Keep 50% of overlap time free. Schedule standups and critical discussions. Leave the rest for flexible collaboration.
Ignoring Daylight Saving Time
Europe changes clocks twice a year. Most Asian countries do not. This shifts your overlap by one hour for half the year.
When Europe springs forward in March, you lose an hour of overlap. When Europe falls back in October, you gain an hour back.
Mark these dates on your calendar. Adjust meeting times accordingly. We worked with one startup that forgot about daylight saving time. Half the team showed up an hour late to sprint planning.
Assuming Everyone Wants Early/Late Hours
Some developers love starting early or working late for extra overlap. Others hate it. Do not assume.
Ask during hiring. Some candidates specifically want standard hours. Others are flexible. Hire people whose preferences match your needs.
One developer we placed was happy to start at 7 AM Vietnam time for a London team. Another candidate turned down the same role because they needed to drop kids at school at 8 AM. Both are valid preferences.
Salary and Cost Comparison: Asia vs Europe
Time zones are one factor in hiring decisions. Cost is another. Here is what developers cost in different locations.
| Location | Mid-Level Developer (3-5 years) | Senior Developer (5-8 years) | Annual Cost (Including Benefits) |
|---|---|---|---|
| London, UK | £50,000-70,000 | £70,000-100,000 | £60,000-120,000 |
| Berlin, Germany | €50,000-65,000 | €65,000-90,000 | €60,000-110,000 |
| Paris, France | €45,000-60,000 | €60,000-85,000 | €55,000-100,000 |
| Ho Chi Minh, Vietnam | $24,000-36,000 | $36,000-60,000 | $30,000-70,000 |
| Manila, Philippines | $18,000-30,000 | $30,000-48,000 | $24,000-60,000 |
| Jakarta, Indonesia | $20,000-32,000 | $32,000-50,000 | $26,000-62,000 |
These numbers come from our Asia Tech Salary Index and Forbes salary data for European developers. The cost difference is significant. A senior developer in Vietnam costs 40-50% less than the same level in Berlin.
But cost is not the only factor. You also need to consider time zone fit, communication skills, technical expertise, and cultural alignment. The best hire is not always the cheapest. It is the one who fits your team and can work effectively across the time difference.
How to Structure Your Distributed Team
Team structure matters as much as individual time zones. Here is what works.
Keep Squads in One Region
If you have multiple squads or feature teams, keep each squad in one region. Do not split a squad across Asia and Europe.
A mobile app startup we worked with made this mistake. They put two backend developers in Vietnam and two in Amsterdam on the same squad. The squad could never meet as a full team. Decisions took forever.
They restructured. One squad fully in Amsterdam. One squad fully in Vietnam. Each squad moved faster. Cross-squad dependencies were managed async or during overlap hours.
Assign Clear Owners
Every feature, service, and system needs a clear owner. When something breaks at 2 AM Vietnam time, who fixes it?
Unclear ownership creates gaps. Everyone assumes someone else will handle it. Or you get duplicate work because two people did not know the other was working on it.
One SaaS company we worked with uses a RACI matrix. For every service: who is Responsible, who is Accountable, who is Consulted, who is Informed. This prevents confusion across time zones.
Build Redundancy
Do not let one person in one time zone be the only expert on a critical system. If they are asleep and it breaks, you are stuck.
Pair developers across time zones on important projects. A senior developer in Europe and a mid-level developer in Asia work together. Both learn the system. Both can fix issues.
This also helps with knowledge transfer. When the European developer goes on vacation, the Asian developer can handle things. And vice versa.
Legal and Compliance Considerations
Hiring across Asia and Europe involves legal complexity. You need to handle contracts, taxes, benefits, and local labor laws.
Most startups use an Employer of Record (EOR) service. The EOR legally employs the developer in their country. You pay the EOR. The EOR handles payroll, taxes, benefits, and compliance.
We offer EOR services across Southeast Asia. This lets European startups hire developers in Vietnam, Philippines, Indonesia, Malaysia, and Singapore without setting up local entities.
The cost is typically 10-15% of salary. For a $3,000/month developer, that is $300-450/month. This covers all legal and HR admin. It is much cheaper than setting up your own entity in each country.
Another option is contractor agreements. The developer works as an independent contractor. This is simpler but has risks. Many countries reclassify contractors as employees if they work exclusively for one company. This can trigger back taxes and penalties.
According to SHRM data on contractor misclassification, 30% of companies face legal issues from improper contractor classification. An EOR eliminates this risk.
Building Culture Across Time Zones
Culture is harder when people never meet in person. Here is what helps.
Regular Video Calls
Make video mandatory for important meetings. Seeing faces builds connection. You pick up on tone and body language. This reduces misunderstandings.
One startup we worked with does “camera on” standups. Everyone turns on video. It feels more like a real team meeting. Less like talking to profile pictures.
Annual Offsites
Bring the team together once or twice a year. Choose a location between Europe and Asia. Dubai, Istanbul, or even Bali work well.
A week together builds relationships that last months. Developers who have met in person communicate better remotely. They give each other more benefit of the doubt.
The cost is significant. Flights, hotels, and activities for 10 people can run €20,000-30,000. But the team cohesion is worth it according to our clients.
Async Social Time
Create Slack channels for non-work topics. Gaming, cooking, pets, whatever your team is into. This casual interaction builds friendships.
One team we worked with does “show and tell” Fridays. Someone records a 5-minute video about something they are learning or working on outside of work. It humanizes everyone.
When Asia-Europe Time Zones Do Not Work
Honesty time. Some situations do not work well with Asia-Europe time zones.
Early-Stage Startups
If you are pre-product-market fit and pivoting every week, you need tight synchronous collaboration. The 2-4 hour overlap is not enough.
Wait until you have a clear product direction and stable roadmap. Then distributed teams work better.
Customer-Facing Roles
If your customers are all in Europe and need real-time support, an Asian team has challenges. Support requests come in when they are asleep.
This works better for internal tools, infrastructure, and backend systems. Less well for customer support or sales engineering.
Highly Regulated Industries
Some industries require developers to be in specific countries for data residency or compliance. Banking, healthcare, and government contracts often have these restrictions.
Check your compliance requirements before hiring across regions.
Getting Started with Asia-Europe Remote Teams
Here is a practical plan if you want to start hiring in Asia from Europe.
Step 1: Pick your target country. Vietnam and Indonesia offer the best overlap with Central Europe. Philippines has better English but less overlap. Use our developer rate card to compare costs.
Step 2: Start with one developer. Do not hire a whole team at once. Hire one strong developer. Learn how to work across time zones. Build your systems and processes. Then scale up.
Step 3: Set up legal infrastructure. Use an EOR service or work with a local partner. Do not try to figure out Vietnamese or Indonesian labor law yourself.
Step 4: Define core hours. Pick a 2-3 hour window when everyone is available. Schedule critical meetings then. Keep the rest flexible.
Step 5: Invest in async tools. Set up good documentation systems. Use Loom for video updates. Make sure your code review process works async.
Step 6: Measure and iterate. Track how long PRs take to get reviewed. How long bugs take to fix. How often you need synchronous meetings. Adjust based on data.
One AI startup we worked with followed this plan. They hired one AI developer in Vietnam. Spent 3 months learning. Then hired three more. Now they have 8 developers across Hanoi and Ho Chi Minh. They ship faster than when their whole team was in Berlin.
Conclusion
Asia-Europe time zones are challenging but manageable. The key is picking the right locations and building the right systems.
Vietnam and Indonesia give you 3-4 hours of overlap with Central Europe. This is enough for daily standups, code reviews, and critical discussions. The rest works async with good tools and clear processes.
The cost savings are real. You can hire excellent developers for 40-50% less than European salaries. The talent quality is high. The tech ecosystems in Ho Chi Minh, Manila, and Jakarta are growing fast.
But success requires discipline. You need clear core hours. Strong async communication. Good documentation. And realistic expectations about what works remotely versus what needs synchronous time.
The startups that make this work see real benefits. Faster development cycles. Access to wider talent pools. Lower costs. And often better work-life balance for everyone.
Hire vetted remote developers from Southeast Asia with Second Talent to build your distributed engineering team with optimal time zone overlap and proven processes for Europe-Asia collaboration.
