ABOUT

A small senior studio, on purpose.

b7dev has built software for founders since 2011. We are registered in Uruguay and work across Latin America with clients in the US, UK and Europe. Two principal engineers lead every project; a vetted bench of developers builds alongside them. We stay small because senior attention is the product.
