Mobile Engineer at Triplespeed in Bengaluru

About Triplespeed

We incubate viral consumer brands for the US and EU markets and scale them until they become independent companies.

In the last 14 months, we took three apps, across three unrelated verticals, from zero to over $70M in combined annual run rate. We did this bootstrapped, with no outside capital. We’re one of the fastest-growing bootstrapped companies in the world.
