HeyDev is an AI engineering studio for software companies. We build MCP servers and ChatGPT, Claude and Copilot apps for SaaS products, AI agents and RAG features, and voice AI agents, and we provide dedicated senior AI engineers on a monthly basis.

Who is behind HeyDev?

HeyDev is run by its three co-founders: Mahima Arora (ex-Microsoft, IIT Kanpur), Yatish Goel (IIT Kanpur, US startup engineer) and Akshit Ahuja (previously at Spinny, a $1B+ startup). The team also includes an ex-Google engineer. Clients work directly with the founders.

What is an MCP server and why does my SaaS need one?

MCP (Model Context Protocol) is the open standard that lets AI assistants like ChatGPT, Claude and Copilot call your product securely. An MCP server exposes your product as tools those assistants can use, so your customers can work with your product from inside their AI assistant.

How fast can HeyDev start?

Usually within the same week. Timelines depend on scope, but we are built for speed: senior engineers from day one, no handoffs to junior teams, and weekly demos.
