The story behind Alloy

Simon co-founded the company with Christian after their time working at Canva and Atlassian. They founded the company with one mission: give product leaders new superpowers.

Initially, they focused on the workflow of planning and prioritization. But with AI, they started to notice PMs could finally do the work, rather than just plan it. They completely re-oriented the company to build a dedicated tool for this new PM workflow.

The problem is that even with new AI app builder tools, PMs are struggling with off-brand prototypes. Using chat to prototype is powerful, but the outputs didn’t look anything like their existing app.

They felt that your prototypes should look like your actual product.

So starting today, they actually can.
