AI-powered engineers
We are AI-powered engineers.
Senior engineers from day one. No subcontractors. No turnover. The team you meet is the team that writes your code.
What we do
Two ways we work with you.
Staff Augmentation
Need extra firepower?
We integrate seamlessly with your existing team. Same quality, same stability, no ramp-up time. Our senior engineers hit the ground running.
End-to-End Delivery
From concept to deployment.
We handle architecture, development, AI integration, and DevOps. You get a production-ready product built by the same team from day one.
Why Yellowspot
Built different, on purpose.
All in. Always.
Our co-founders have 15+ years of experience each, and every engineer on the team is senior. No juniors. No freelancers. No subcontractors.
Zero turnover.
The team you meet in the kickoff is the exact same team that delivers the final deploy. We're small by design—you get consistency, not a revolving door.
AI-powered, not AI-replaced.
We use AI to accelerate our senior workflow—boilerplate, testing, refactoring. Never to replace architectural thinking. This gives you enterprise speed with the quality of a dedicated, experienced team.
Our Team
Meet the co-founders.
They work alongside our senior developers, leading by example and writing code every day. We’re a small, focused team, and we bring that collective experience to every project.
