About CoreTeam.io

CoreTeam.io sets up and runs engineering teams for GenAI and deep-tech startups, based in Serbia and Bulgaria. Each engagement starts with a senior lead engineer who delivers from the first day, and the team then grows around the founder's own product and culture, with the client owning the result.

What CoreTeam.io offers

  • Dedicated engineering teams — engineers who work only on one client's product.
  • Lead engineer from day one — a senior engineer who ships code while the team is being hired.
  • GenAI engineering — AI infrastructure, features built on large language models, and model training and tuning.
  • Performance and scaling — fixing infrastructure bottlenecks and performance problems across the stack.
  • Full-stack and DevOps — front-end, back-end and DevOps work in Python, Node, React, Vue and Java.

Who it works with

CoreTeam.io works with GenAI and deep-tech startups and their founders, and earlier worked with enterprises and startups more broadly.

Key facts

  • Locations: Serbia and Bulgaria
  • Model: three-step process, with the team fully owned by the client
