Senior AI engineers for software companies. You work with the founders, not a sales team.
HeyDev is a small AI engineering studio run by three founders who still write the code. We help SaaS and software companies in Europe, the US and the UAE add AI to their products, and we make sure it holds up once real customers use it. What we do: - MCP servers and AI apps: make your product usable from inside ChatGPT, Claude and Copilot, with proper OAuth and security. - AI agents and RAG: agents that handle real work in your product, grounded in your own data, with evals so they keep working after launch. - Voice AI: phone agents that answer, qualify and book around the clock, connected to your phone system, WhatsApp and CRM. - Senior AI engineers, monthly: one of our engineers joins your team and your repo, overlapping European and US hours. Recent work: an AI tax assistant for US gig workers (LightTaxes), an 11-agent system that tests mobile apps on real devices (Zailens), and a voice AI calling platform we built and still run. The founders come from Microsoft, IIT Kanpur and a $1B+ startup, with an ex-Google engineer on the team. Every project starts with a short call, then a fixed plan, weekly demos, and code you own from day one.

Starting from

  • Description
    We build AI features that actually make it to production. That might be an agent that handles a real workflow inside your product, or a RAG system that answers questions from your own docs and data. We start with a short call to find the one use case worth building first. Then you get a fixed plan, weekly demos, and evals so you know the thing works before your customers touch it. You talk to the founders the whole way through, and you own all the code.

  • Description
    Your customers are starting to work inside ChatGPT, Claude and Copilot. We make your product usable from there. We build MCP servers and AI app integrations with proper OAuth, sensible tool design and security baked in, so the assistant can safely read and act on your product's data. A typical first version ships in three to four weeks, and we stay on to help you roll it out to customers.
