Signaly.

Signaly started in February 2026 during the entrepreneurship minor at the HvA. Sales teams usually work from static lead lists. Signaly looks for moments instead: a company that just raised money, is hiring or changed its website is more likely to be open to a conversation.

The backend is a Python API on FastAPI and PostgreSQL that runs every lead through discovery, enrichment and scoring, with OpenAI doing the research and writing. The web app is built in React with TypeScript. Both run on our own TransIP server, and every push to main goes through tests before it is deployed automatically.
