At Kraftful, we're building the AI Co-Pilot for product managers and other product builders. Our mission is to help product folks leverage GPT-4 and ChatGPT API to listen to users at scale and actively involve them in the development process.

Since our beta launch, we've seen tremendous growth, with thousands of users joining our platform (30% WoW growth). Kraftful is now used by product builders from major tech companies (Meta, Google, Netflix, Atlassian, Canva, Dropbox, etc.), global retail brands (Gap, 7-Eleven, J&J), car manufacturers (Ford, Volvo), public agencies (London Tube, National Art Gallery), financial institutions (Banco de Brazil), and even the City of Philadelphia! We're now expanding our small but mighty engineering team to keep up with demand. This is a unique opportunity to become an early employee at a rocketship.

We’re a team that puts users first. We make hard, pragmatic decisions. Constant iteration is at the core of our product and company. Empathy is our superpower.
