For VPs of Engineering and CTOs growing from 5 to 25 engineers post-Series A or B. Offshore (India, Vietnam) is too slow (4 to 6 months per senior) and too expensive ($350K+ fully-loaded for SF/NYC). Polish nearshore: senior engineers at 30 to 35% of US cost, retention 90%+ at 12 months, EST/CST overlap, EU GDPR jurisdiction, 90-day ramp.
Trusted by teams across Europe
Scaling 5 to 25 engineers in-house in 12 months means hiring ~20 senior engineers in a market with 18-month average vacancy. Even with great recruiter, you pay $400K+ fully-loaded per senior, lose 40% to attrition before they ramp, burn 18 to 24 months of runway. Hybrid: 5 to 8 in-house senior + 12 to 17 nearshore senior, all reporting to your tech lead. 30 to 35% US cost, 90% retention, productivity to par at 90 days. We have done this for 30+ Series A to C clients.
| Option | Time to scale to 20 engineers | Total cost Y1 (20 senior eng) | Retention at 12 months | Risk |
|---|---|---|---|---|
| Hybrid (US + Polish nearshore) | 6 to 9 months | $2.4 to $3.5M Y1 | 90% (we measure) | Low — bench available for surges |
| 100% in-house (US, SF/NYC) | 14 to 22 months | $6.5 to $9M Y1 fully-loaded | 60 to 75% (Big Tech poaching) | High — long unfilled roles, recruiting drain |
| 100% nearshore LatAm (Andela, BairesDev) | 6 to 8 months | $1.9 to $2.8M Y1 | 50 to 65% (junior-heavy retention) | Medium — junior burnout, ramp pain |
| Big Tech recruiting via agency | 8 to 14 months | $7 to $11M Y1 fully-loaded | 40 to 50% (counter-offers) | Medium — payback 3+ years |
| Offshore (India, Vietnam) | 4 to 6 months | $1.4 to $2.2M Y1 | 40 to 55% (timezone burnout) | High — async-only, slow iteration |
| Polish nearshore (full team) | 4 to 6 months | $2.0 to $2.9M Y1 | 90%+ (best in class) | Low — EU jurisdiction, EST overlap |
Honest take: hybrid (US senior leadership + Polish nearshore execution) outperforms pure plays for Series A to C. 100% US is too expensive past Series A. 100% offshore burns out at scale beyond 10 engineers. Polish nearshore: EU jurisdiction, EST overlap, retention near US in-house numbers, at 30 to 35% of US cost. See cost analysis.
Pattern across recent scale-ups: post-Series A teams growing 5 to 15, post-Series B teams 15 to 30, mature SaaS reducing US cost, regulated industries needing EU GDPR, healthcare needing HIPAA-eligible scale.
Tell us what you need →Critical sprint mid-flight, knowledge transfer needed, in-house replacement is 90+ days away. We staff a senior backend engineer in 7 days for 30 to 90 day knowledge-transfer engagement, optionally permanent.
2 to 3 senior React engineers, 60 to 90 day surge to unblock product launch. Pair with your tech lead, ship features, hand off cleanly. No agency overhead, just engineering capacity on tap.
Internal recruiting will take 90 to 120 days. Investors expect velocity now. We staff a full nearshore squad in 7 days, while your in-house recruiter ramps the permanent team in parallel. Bridge the gap.
Code is in disarray, communication broken, deadlines slipping. We do a 5-day code audit, propose stabilization plan, then staff 2 to 4 engineers to take over. Existing engagement transitions cleanly within 30 days.
Compliance audit forced a hard deadline. Specialized engineers (security, infra, audit-trail logging) needed for 60 to 90 days. We have bench engineers with prior SOC 2 Type 2, HIPAA and GDPR audit experience. Day 7: PR review for compliance gaps.
Day 1 to 3: shortlist of 2 to 3 candidates from our pre-screened bench, matching your stack, timezone preference, seniority and domain. Tech profiles, GitHub, prior projects, English level (CEFR scored).
Day 3 to 4: your tech lead does a 60-minute pair-programming or system design interview. We do not skip your screening, we accelerate ours.
Day 5 to 6: standard EU MSA (English law optional, EU GDPR jurisdiction default), 30-day notice, IP assignment to client from day one. No billable hours minimum, no exclusivity, no auto-renew traps.
Day 6: GitHub access, Slack invite, Jira/Linear ticket assignment, dev environment running locally, first PR draft already open. Engineer ready to ship Monday morning your timezone.
From day 7: 15-minute daily standup at your preferred time slot (typically 9 to 10am EST = 3 to 4pm Krakow). Live Slack overlap 4 to 6 hours per day, async covers the rest.
End of week 1: paired commit reviewed by your tech lead, deployed to staging, integrated with your existing CI/CD. We measure success by commits in your repo, not hours billed.
If the engineer is not the right fit by day 30, we replace within 5 business days at no cost. You only pay for hours actually worked. Engineer departures are typically zero (90%+ retention) but the safety net is there.
Every 90 days: written engineer performance review, satisfaction survey, ramp-up plan. You can scale up, scale down or end engagement with 30-day notice. No long-term lock-in.
Hybrid scale: US in-house tech leadership (CTO, VP Eng, staff/principal) + Polish nearshore execution layer. Time and materials on nearshore side, monthly invoicing, scale up/down with 30-day notice. For rate cards, see nearshore rates 2026.
Add 5 to 7 senior nearshore engineers to your existing 5-eng team. Frontend, backend, DevOps mix per roadmap. Your tech lead remains on US side. We provide engagement manager.
Series B scale-up. Build out execution layer of 12 to 15 nearshore engineers reporting to your VP Eng. 1 nearshore engineering manager (we hire) on the ground. 90-day ramp playbook included.
Reduce US fully-loaded cost by 50 to 65% while maintaining velocity. Migrate execution to Polish nearshore over 12 to 18 months while keeping US tech leadership. Rebadging available for partial transitions.
Current team size, attrition rate, hiring funnel, runway, growth target, technical leadership availability. We map current state and propose hybrid model: how many to keep US, how many to add nearshore, where to put the seam. Output: scale-up playbook with milestones.
Start with smallest viable team to validate model. Senior engineers paired with your existing US tech lead. Daily standups, weekly tech reviews, monthly retro. Measure: velocity ramp curve, code review quality, integration friction.
By month 3, first cohort is at 80 to 90% productive. Hire nearshore engineering manager (we recruit) to take 1:1s, performance reviews, mentorship. Your US tech lead transitions from operational to strategic. Velocity stable.
Add 2 to 4 engineers per month based on roadmap. By month 6, full target headcount reached. Promotions: best engineers move into tech lead, staff, principal roles. Career ladder identical to US side.
Quarterly business review with your CTO/VP Eng: velocity metrics, retention, cost trajectory, what to scale up/down. Most clients renew annually with 5 to 15% headcount growth. Some transition engineers to permanent in-house hires (placement fee, no penalty).
Pattern that works for Series A to C: keep US senior leadership (CTO, VP Eng, staff/principal) in-house, build execution layer (senior + mid + DevOps) nearshore. US side does architecture, hiring decisions, customer interactions; nearshore ships code daily.
Result: 30 to 35% of all-US cost, 90%+ retention at 12 months, velocity at par or better. The seam between US and nearshore is engineering management and architecture decisions, not the code itself.
See full case study6 to 9 months for sustainable scale. First 5 nearshore engineers in month 1. Add 2 to 4 per month. By month 6, target reached and engineering manager in place. Compare: 100% in-house US scaling 5 to 20 takes 14 to 22 months due to recruiter throughput and 60% attrition during ramp.
20 senior engineers nearshore: $2.0 to $2.9M Y1. Same 20 in SF/NYC: $6.5 to $9M Y1. Hybrid (5 US senior leadership + 15 nearshore execution): $2.4 to $3.5M Y1. Hybrid is the sweet spot: keep top architecture and customer judgment in US, build execution velocity in nearshore.
Hybrid keeps US tech leadership (CTO, VP Eng, principal) for: customer interactions, fundraising support, architecture, hiring calibration. Nearshore handles: feature development, infrastructure, DevOps. The seam is engineering management. Full offshore breaks down at scale beyond ~10 engineers due to timezone and cultural distance.
Our 12-month retention is 90%+ vs ~75% for typical Polish IT and 60% for offshore Asia. Why: we pay top-quartile of Polish market, career ladder identical to US, US client diversity, conferences and training. When attrition happens, we have bench depth to fill within 5 days, no project disruption.
Two cases: (1) US security clearance for defense AI cannot be done nearshore. (2) $100M+ raised and budget not the constraint, building world-class engineering brand to attract Anthropic/OpenAI alumni is worth the premium. For Series A to mature SaaS ($0 to $50M ARR), hybrid wins on cost, retention, and velocity.
30-day notice. No minimum hours, no minimum months, no auto-renew. You can engage for 4 weeks of surge work and end with 30-day notice. You can scale up from 1 to 5 engineers and back. Most clients stay 6+ months because the model works, not because of contractual lock-in. We measure success by retention and renewal, not by clauses.
