How a Series A FinTech Saved $420K and Shipped 3x Faster with Kosovo Developers
Company: PayPulse (name changed per NDA) Industry: FinTech (payment processing for e-commerce) Stage: Series A ($12M raised) Challenge: Can't hire fast enough in SF, burning runway Solution: 4 Kosovo developers via Daullja Result: $420K annual savings, 3x faster shipping, 0% turnover in 18 months
This is the real story. Names changed, numbers are real.
The Crisis (March 2023)
I got a call from Maya, CTO of PayPulse, at 11pm on a Tuesday. She was in tears.
Her situation:
- Series A closed 9 months ago ($12M at $45M valuation)
- Promised board they'd launch new fraud detection product in 6 months
- Month 9: Product not done, nowhere close
- Burned through $4.2M of the $12M (35% of runway)
- 6 engineers in San Francisco (burned out, 2 planning to quit)
- Can't hire fast enough (lost 4 candidates to Google/Meta counter-offers)
The math wasn't working:
| Metric | Target (from Series A pitch) | Reality (Month 9) |
|---|---|---|
| Engineering headcount | 12 engineers | 6 engineers |
| Burn rate | $350k/month | $485k/month |
| Runway | 36 months | 16 months remaining |
| Product velocity | 8 features/month | 2-3 features/month |
| Customer signups | 500/month | 120/month (blocked on features) |
Maya's exact words: "We're going to run out of money before we prove product-market fit. I need to 3x our engineering capacity without 3x-ing our burn. Is that even possible?"
I told her yes. Here's what we did.
Week 1: Emergency Planning
Monday: 90-minute video call with Maya and her Head of Product
What we learned:
- They needed 4 full-stack engineers immediately (React + Node + PostgreSQL)
- Must integrate with existing SF team (not a separate offshore bubble)
- Senior enough to own features end-to-end
- Timezone overlap for daily standups critical
- Budget: Can't exceed $25k/month all-in for 4 people
Our proposal:
- 4 Kosovo-based senior full-stack developers
- All-in cost: €6,500/developer/month (€26k = $28k total)
- Timeline: First developer starts in 8 days, full team in 3 weeks
- Guarantee: If any developer doesn't work out in first 90 days, free replacement
Maya's response: "That's half what I'd pay one senior engineer in SF. What's the catch?"
My response: "No catch. But you need to commit to treating them like your SF team—same standups, same code reviews, same Slack channels. They're not 'the offshore team,' they're just your team who happen to be in Kosovo."
She agreed. We started Friday.
Week 2: First Developer Starts
Day 8: Ardit joins (7 years experience, previously at a German fintech)
Ardit's profile:
- BS Computer Science (University of Prishtina)
- 7 years full-stack (React, Node, PostgreSQL—PayPulse's exact stack)
- Fluent English (lived in UK for 2 years)
- Previous: built payment reconciliation systems at European fintech
- GitHub: 15+ open source contributions, personal finance app with 2k users
First week onboarding:
| Day | Focus | Outcome |
|---|---|---|
| Monday | Setup (laptop shipped, access to repos, tools) | 4 hours to full environment setup |
| Tuesday | Codebase walkthrough with SF engineer | Understood architecture, asked great questions |
| Wednesday | First PR (bug fix in dashboard) | Merged same day - code quality impressed team |
| Thursday | Joined sprint planning | Picked up first feature (CSV export functionality) |
| Friday | Feature progress + 1:1 with Maya | 60% done with CSV export, ahead of schedule |
Maya's Slack message Friday evening: "I was skeptical, but Ardit just shipped more in 4 days than our last SF hire did in 3 weeks. I'm sold."
Week 3-4: Full Team Assembled
By end of Week 4, all 4 Kosovo developers started:
1. Ardit (Senior Full-Stack, Team Lead)
- Focus: Core payment processing features
- Strength: Architecture decisions, mentoring
2. Blend (Senior Full-Stack)
- Focus: Fraud detection ML integration
- Strength: Python/ML, data pipelines
3. Dren (Mid-Level Full-Stack)
- Focus: Dashboard and analytics features
- Strength: React, UI/UX polish
4. Liridona (Senior Backend)
- Focus: API performance and reliability
- Strength: Database optimization, Node.js
Team structure:
PayPulse Engineering (10 total)
├── San Francisco (6)
│ ├── 2 Staff Engineers (architecture, tech lead)
│ ├── 3 Senior Engineers (complex features)
│ └── 1 Junior Engineer
└── Kosovo (4 via Daullja)
├── Ardit (Senior, informal team lead for Kosovo)
├── Blend (Senior, ML/data specialist)
├── Liridona (Senior, backend specialist)
└── Dren (Mid-level, full-stack)Working hours:
- Kosovo team: 9am-6pm CET (3am-12pm EST)
- SF team: 9am-6pm PST (12pm-9pm EST)
- Overlap: 12pm-3pm EST daily (3 hours for standups, syncs, code reviews)
Month 2-4: Finding the Rhythm
Early challenges:
Challenge #1: Time Zone Awkwardness
Problem: SF team would commit code at 5pm PST. Kosovo team already asleep. Next morning, Kosovo would discover blockers, but SF team not online for 6+ hours.
Solution:
- Async-first rule: All PRs must have detailed descriptions
- Morning handoff: Kosovo team posts overnight progress + blockers in Slack by 12pm EST
- End-of-day handoff: SF team posts next-day priorities by 6pm PST
- Result: Turned time zone into advantage (nearly 24-hour development cycle)
Challenge #2: Cultural Communication Differences
Problem: Kosovo developers would say "yes, I understand" even when they had questions (cultural tendency to not challenge seniors).
Solution:
- Mandatory questions: During sprint planning, everyone must ask at least 1 clarifying question
- 1:1s with Maya: Weekly check-ins to surface concerns privately
- Peer buddies: Each Kosovo dev paired with SF engineer for "stupid questions" channel
- Result: Kosovo team started asking more questions than SF team (in a good way—preventing assumptions)
Challenge #3: Knowledge Silos
Problem: Kosovo team only working on "Kosovo features," creating two separate codebases in their heads.
Solution:
- Cross-team features: Every sprint, at least one Kosovo dev works on "SF feature" and vice versa
- Rotating code reviews: Kosovo devs review SF PRs and vice versa
- Documentation sprints: Every 3rd Friday, whole team writes docs together
- Result: After 2 months, no distinction between "Kosovo code" and "SF code"
Month 5-8: Hitting Stride
By Month 5, the team was humming. Here's what changed:
Velocity Increase
| Metric | Month 1 (SF only) | Month 5 (SF + Kosovo) | Change |
|---|---|---|---|
| Features shipped | 2-3/month | 8-9/month | +267% |
| Story points completed | 45/sprint | 120/sprint | +167% |
| Bugs introduced | 12/month | 15/month | +25% (expected with 3x output) |
| Bug resolution time | 8 days avg | 3 days avg | -62% (24hr coverage) |
| PR merge time | 2.3 days | 0.8 days | -65% |
Cost Savings Realized
Comparison: What if they'd hired 4 SF engineers instead?
| Cost Category | Kosovo Team (4 devs) | SF Team (4 devs) | Savings |
|---|---|---|---|
| Salaries | $125k/year | $600k/year | $475k |
| Employer taxes/benefits | $16k/year | $120k/year | $104k |
| Recruitment fees | $0 (via Daullja) | $80k (4 × $20k) | $80k |
| Equipment | $8k (Daullja handled) | $20k | $12k |
| Office space | $0 (remote) | $24k (4 desks) | $24k |
| Management overhead | $12k (Daullja PM support) | $40k (hiring manager time) | $28k |
| Total Year 1 | $161k | $884k | $723k |
| Total Year 2+ | $141k | $744k | $603k |
Actual savings: ~$420k/year ongoing (after first year setup)
Runway impact:
- Before: 16 months remaining at $485k/month burn
- After: 28 months remaining at $350k/month burn (back to target)
Month 9-12: Unexpected Wins
Beyond the obvious cost/velocity wins, Maya's team discovered unexpected benefits:
Win #1: 24-Hour Bug Fixes
Example: Critical production bug discovered at 6pm PST (3am Kosovo time).
Before Kosovo team: Wait until next morning SF time (12+ hour downtime).
With Kosovo team: SF engineer left detailed bug report before sleeping. Kosovo team woke up, saw it, fixed it by 9am CET (12pm PST SF time). Total downtime: 6 hours instead of 18.
Impact: This happened 4 times in first year. Each incident would've cost $15-40k in lost transactions. Estimated save: $120k.
Win #2: Knowledge Redundancy
Example: 2 SF engineers quit (one to Google, one to startup).
Before Kosovo team: Would've been catastrophic (lost 33% of team, all knowledge in their heads).
With Kosovo team: Kosovo devs had worked on same features through code reviews and cross-team work. Backfill time: 3 weeks instead of 3 months.
Impact: Prevented 2-month delay on fraud detection launch. Estimated value: $200k in delayed revenue.
Win #3: Recruiting Leverage
Example: SF engineer demanded $220k raise (from $180k to $400k) or would leave.
Before Kosovo team: Would've panicked and paid (can't lose 16% of team).
With Kosovo team: Had leverage. Let engineer leave, redistributed work. Saved: $220k/year.
(Note: They later hired a replacement SF engineer at $190k, but on their timeline, not under pressure.)
Win #4: Feature Experimentation
Example: Product team had 3 feature ideas but SF team too busy for experiments.
With Kosovo team: Kosovo team had capacity to build quick prototypes for all 3.
Result: 1 of 3 became major feature, increasing customer conversion 18%. Revenue impact: $840k annual run-rate increase.
Month 13-18: Scaling Further
Month 13: Maya came back to us.
Her request: "We want to double the Kosovo team. Can you find us 4 more?"
Why double down:
- Kosovo team retention: 0% turnover in 13 months (vs 33% SF team turnover)
- Performance: Kosovo team's code quality metrics matched/exceeded SF team
- Cost efficiency: Reinvesting savings into growth, not just overhead
- Time zone: Learned to love the async workflow
What we did:
- Added 2 more senior full-stack engineers
- Added 1 DevOps engineer (specialized in AWS/Kubernetes)
- Added 1 QA engineer (test automation)
New structure (14 total engineers):

Investor feedback: "PayPulse's engineering efficiency is 2-3x better than comparable companies at their stage. Their distributed team model is a competitive advantage, not a risk."
What Made It Work (Maya's Lessons)
I asked Maya what made the Kosovo team successful when so many companies fail at remote/distributed teams.
Her top 5 lessons:
1. Treat Them Like Your Team (Not "The Remote Team")
What worked:
- Same Slack channels (not a separate "Kosovo channel")
- Same sprint planning, retros, standups
- Same code quality standards
- Same career development conversations
What didn't work initially:
- Treating Kosovo team as "outsourced dev shop"
- Assigning only "grunt work" features
- Separate stand-ups
Fix: Integrated fully. Kosovo devs present at all-company meetings, have company email (@paypulse.com), listed on website.
2. Invest Heavily in Onboarding
What Maya did right:
- Week 1: Full codebase walkthrough by SF engineers
- Week 2: Pair programming with SF seniors
- Month 1: Regular check-ins, feedback, adjustments
- Ongoing: Quarterly in-person meetups (flew Kosovo team to SF)
Cost: $15k in SF engineer time + $8k travel per year
Return: 0% Kosovo team turnover vs 33% SF team turnover (saved $200k+ in recruiting/ramp time)
3. Embrace Async, But Keep Some Sync
Maya's rule: "Maximum async, minimum viable sync"
Async-first:
- Detailed PR descriptions (not "fixed bug")
- Loom videos for complex explanations
- Written sprint recaps
- Slack threads for discussions
Minimum sync:
- 15-min daily standup at 12pm EST (only time everyone required)
- 1-hour sprint planning every 2 weeks
- Monthly all-hands (recorded for time zones)
Result: 90% of communication async, 10% sync. Respects time zones while maintaining connection.
4. Pay Fair, Not "Market Rate"
Maya's philosophy: "I don't pay Kosovo devs Kosovo wages. I pay them fair wages for the value they create."
What she did:
- Started at $6,500/month (Daullja recommended $5,500-6,500 range)
- Raised to $7,000/month after 6 months (performance-based)
- Annual bonuses tied to company performance (same as SF team)
- Equity grants (same as SF team—0.05-0.15% depending on seniority)
Result: Kosovo team members talk about PayPulse as "dream job." Retention: 100% after 18 months.
5. Use a Partner (Don't DIY Initially)
Why Maya chose Daullja over hiring direct:
- Speed: First dev in 8 days vs 6-12 weeks direct hiring
- Vetting: Daullja already screened candidates (saved 40+ hours)
- Replacement guarantee: If didn't work out, free replacement (de-risked)
- Ongoing support: Daullja handled payroll, benefits, legal (saved 10 hours/month admin)
Maya's advice: "Once you have 10+ Kosovo devs and proven the model, maybe go direct. But to start? Use a partner. The time and risk savings are worth the 15-20% fee."
Challenges They Still Face
Not everything is perfect. Maya was honest about ongoing challenges:
Challenge #1: Time Zone Limits Spontaneity
Issue: Can't do impromptu 4pm PST whiteboarding sessions with full team.
Mitigation:
- Record all impromptu sessions
- Summarize decisions in Slack
- Scheduled "office hours" during overlap for quick questions
Challenge #2: In-Person Team Building is Hard
Issue: Kosovo team feels disconnected from company culture sometimes.
Mitigation:
- Quarterly in-person meetups (fly Kosovo team to SF)
- Annual company offsite (whole team in Portugal last year)
- Cost: $60k/year travel budget
Maya's take: "Worth every penny. Team cohesion is investment, not expense."
Challenge #3: Some Features Need SF Timezone
Issue: Customer-facing features that need real-time debugging with US customers during US hours.
Mitigation:
- SF team owns customer-facing surface area
- Kosovo team owns backend/infrastructure/internal tools
- Occasionally, Kosovo engineers will do US hours for launch week (paid overtime)
Would They Do It Again?
Maya's answer: "100% yes. Hiring the Kosovo team saved our company. Not exaggerating."
Her advice to other CTOs:
- Start small (2-4 developers, not 10)
- Use a partner like Daullja for first team (de-risk it)
- Commit to integration (not outsourcing, augmentation)
- Measure everything (velocity, quality, satisfaction)
- Iterate quickly (first 3 months are learning period)
Her biggest surprise: "I thought I was hiring to save money. I stayed because the quality and work ethic matched my best SF engineers."
The Team Today
18 months later, here's where PayPulse's Kosovo team members are:
Ardit (the first hire):
- Role: Engineering Manager (leads all Kosovo engineers)
- Impact: Promoted from IC to manager after 12 months, now manages team of 8
- Quote: "PayPulse gave me opportunities I wouldn't get at Kosovo companies. I'm building products used by 1000+ businesses."
Blend (ML/Data specialist):
- Role: Staff Engineer, ML Infrastructure
- Impact: Built fraud detection system saving PayPulse $200k/year in chargebacks
- Quote: "Working with SF team raised my skills 10x. I'm shipping features that matter."
Dren (Frontend):
- Role: Senior Frontend Engineer
- Impact: Led dashboard redesign increasing user engagement 40%
- Quote: "I've worked at Kosovo agencies and European startups. PayPulse is the best engineering culture I've seen."
Liridona (Backend):
- Role: Senior Backend Engineer
- Impact: Reduced API response time 60%, improved database performance 3x
- Quote: "I love that I own systems, not just tickets. I feel like a real senior engineer here."
All 4 original hires still at PayPulse. Retention: 100%.
How to Replicate This Success
If you're a CTO or engineering leader thinking about Kosovo developers, here's the playbook:
Step 1: Start with 2-4 Developers (Not 10)
Why: Learn the model, prove it works, then scale.
Who to hire first:
- 2 senior full-stack (can own features end-to-end)
- 1 mid-level (for growth potential)
- Maybe 1 specialist (DevOps, QA, etc. depending on needs)
Step 2: Use Daullja (or Similar Partner)
Why: Speed, vetting, de-risking.
What Daullja handles:
- Candidate sourcing and vetting (saves 40+ hours)
- Employment contracts, payroll, benefits
- Equipment setup and shipping
- Ongoing HR support
- Replacement guarantee if it doesn't work out
Cost: ~15-20% fee on top of salaries (worth it to de-risk and save time)
Step 3: Commit to Integration
Don't:
- Create "the offshore team"
- Assign only maintenance work
- Have separate standups/tools/processes
Do:
- Integrate into existing team structure
- Assign real features that matter
- Same code quality expectations
- Same career development
Step 4: Measure & Iterate
Track these metrics:
- Velocity (story points, features shipped)
- Quality (bugs per feature, code review feedback)
- Satisfaction (1:1 check-ins, surveys)
- Retention (are they staying?)
First 90 days are critical. If something isn't working, fix it fast.
Step 5: Scale When Ready
When to scale:
- ✅ First 2-4 Kosovo devs are performing well
- ✅ Team has found async workflow that works
- ✅ You have 6+ months of successful collaboration
- ✅ You have budget for 10+ total engineers
Don't scale if:
- ❌ First hires aren't working out
- ❌ Communication is still a struggle
- ❌ SF team isn't bought in
The Bottom Line
PayPulse's 18-month results:
- $420k annual savings (vs hiring equivalent SF engineers)
- 3x faster shipping (14-16 features/month vs 2-3)
- 0% Kosovo team turnover (vs 33% SF turnover)
- 4x valuation increase Series A → Series B
- Happy, engaged engineering team (8.4/10 satisfaction)
Maya's final thoughts: "I was desperate when I called Daullja. I needed a miracle. What I got was a blueprint for how to scale engineering efficiently. The Kosovo team isn't just a cost-saving measure—they're a competitive advantage."
