An AI platform for companies. The major language models in one interface, connected to the team's knowledge and tools.

It launched as CorporateLLM. It took the name Relationflow when the CRM that used to carry it was retired.

You switch models mid-conversation. The thread and the project's knowledge stay put. Every answer shows which model wrote it.

By default, the managed models run in EU regions and carry an EU mark in the chat. Models outside the EU stay locked until a team admin releases them.

A custom connection adds open-source models such as Llama, Mistral or Qwen, for example from a server in your own building. They sit in the same picker as GPT, Claude and Gemini.

51 tools can be connected, from Gmail to HubSpot. The chat fetches data right away. Anything that changes, sends or deletes something asks first, every time.

Prompts, skills and agents belong to the team. They live in a shared library. Anyone who wants to improve one sends a proposal; once reviewed, it becomes the new version.

Built as a team. As co-founder and CTO, I was responsible for product and engineering.

Most of the code was written by the team. My own parts include the skill library with versions and review, the Atelier for image generation and group access, which controls who sees which projects, agents and skills. Relationflow and Voicely have over 10,000 users combined.

Built with Next.js, Postgres with pgvector and the Vercel AI SDK. The managed models come through Azure, Google Vertex and AWS Bedrock, among others.
