About Sumo

Free Tools to Automate Your Site Growth.

We've spent over 4 years building these tools internally to grow our AppSumo Newsletter. They helped us grow to over a million subscribers.

We've noticed lots of people struggle to collect emails because the tools just aren't available or are too expensive. So we thought, why not make our tools available for you?

Our goal, plain and simple, is to help you grow your website.
