How HeyGen Scaled Their Dev Team with 9 Senior Engineers in Under 60 Days
HeyGen’s AI video generation platform was growing faster than their engineering team could support. Traditional hiring pipelines could not keep pace. Odesa placed 9 senior engineers from Eastern Europe and Latin America across frontend, backend, and ML engineering roles within 8 weeks, saving HeyGen over $800,000Â in annualized hiring costs while maintaining full US timezone overlap.
The Challenge
HeyGen ($60M Series A) is an AI-powered video generation platform that enables businesses to create professional-quality videos using AI avatars and voice synthesis. As demand for their product surged, HeyGen’s engineering team was stretched thin. They needed senior developers across multiple disciplines — React frontend engineers to build new UI features, Python backend engineers to scale their infrastructure, and ML engineers to improve their core AI models.
The problem was speed. HeyGen’s existing recruiting channels were producing 1-2 hires per month at best, and each hire cost $25-30K in agency fees. At that pace, they were looking at 4-6 months to build the team they needed. In a market where AI competitors were launching new features weekly, that timeline was unacceptable.
Why HeyGen Chose Odesa
HeyGen evaluated several staffing providers including TopTal and freelancer marketplaces. The key differentiators that led them to choose Odesa were placement speed, vetting quality, and the founder-led concierge model. Val personally conducted the discovery call, understood HeyGen’s technical requirements in detail, and committed to delivering matched profiles within 48 hours.
The concierge model meant HeyGen’s engineering leadership did not have to sift through hundreds of resumes or conduct dozens of screening calls. Odesa pre-vetted every candidate against HeyGen’s specific tech stack requirements, coding standards, and communication expectations before presenting them. This saved HeyGen’s VP of Engineering an estimated 60+ hours of screening time across the 8 placements.
Val and his team delivered senior developers faster than our internal recruiting team could schedule first-round interviews. The quality of talent and the speed of placement had considerably higher benchmarks than traditional hiring avenues.
The Solution: 9 Senior Developers in 8 Weeks
Odesa deployed a phased approach to fill HeyGen’s engineering needs. The first two developers — a senior React engineer and a senior Python backend engineer — were placed within 3 days of the initial discovery call. Both started their 2-week risk-free trials immediately and were onboarded into HeyGen’s development workflows within the first week.
Over the following 6 weeks, Odesa placed an additional 6 developers across frontend, backend, DevOps, and ML specializations. Each placement followed the same process: Val matched candidates from Odesa’s pre-vetted network, HeyGen conducted a single technical interview, and onboarding began within 24 hours of acceptance.
| Role | Experience | Tech Stack | Days to Place |
|---|---|---|---|
| Senior Frontend Engineer | 8 years | React, TypeScript, Next.js | 3 days |
| Senior Backend Engineer | 10 years | Python, FastAPI, PostgreSQL | 8 days |
| Senior Frontend Engineer | 7 years | React, Redux, WebSockets | 4 days |
| ML Engineer | 6 years | Python, PyTorch, TensorFlow | 10 days |
| Senior Backend Engineer | 9 years | Python, Django, Redis | 6 days |
| DevOps Engineer | 8 years | AWS, Kubernetes, Terraform | 9 days |
| Senior Full-Stack Developer | 11 years | React, Node.js, PostgreSQL | 4 days |
| ML Engineer | 7 years | Python, PyTorch, MLOps | 4 days |
| Sanity CMS Engineer | 6 years | Sanity CMS, TypeScript, React | 10 days |
The Results
Within 60 days of the initial discovery call, HeyGen had 9 senior developers fully integrated into their engineering workflows. All 9 developers passed their 2-week risk-free trials and continued their engagements past the initial period. As of the time of writing, 8 remain actively engaged with HeyGen – 88% retention rate.
The financial impact was significant. HeyGen’s average cost per developer through Odesa was $45-70/hr, compared to an estimated $140-190K annual salary plus 30% benefits overhead for equivalent US-based hires. Across 9 developers, this translated to approximately $800K in annualized savings.
Beyond cost savings, the speed of deployment allowed HeyGen to ship features ahead of their original roadmap. The additional engineering capacity meant they could pursue parallel workstreams that would have been impossible with their previous team size.
Key Takeaways
HeyGen’s engagement with Odesa demonstrates several principles that apply to any growth-stage company looking to scale engineering quickly. First, the founder-led concierge model eliminates the friction of traditional recruiting — no resume floods, no endless screening calls, no mismatched candidates. Second, pre-vetted Eastern European developers with US timezone overlap deliver the same quality of work at 40-60% lower cost.
