Summary
Fastgen builds a low-code API and workflow builder with an integrated Postgres database. Founded by repeat founders Mike Mahlkow, David Nordhausen, and Constantin Schreiber, who previously co-founded Blair (YC S19) and raised over $100M, they solve the time-consuming process of building backends and integrating third-party APIs. Users create REST endpoints through a drag-and-drop interface, connect to pre-built integrations like Sendgrid and Slack, and deploy with one click without managing hosting or DevOps.
