BUILDINGBAD

What turns a side project
into a business?

We're two engineers at multinational companies who have built, launched and monetized two products on our own. Now we build yours.

Anyone can make a mockup. Getting real people to sign up, and then pay, is harder. We've done it twice, with no team, no funding and no agency. Building Bad brings that same end-to-end ownership to your product.
