Envie: Envelope Challenge

Rapidly building software and teams...

Digital Product


It took TeamWALT too long to build apps that teach people how to save and build wealth.


TeamWALT paired with Sodium Halogen to build the Envie app, a digitized version of the 100 day envelope challenge. Over the course of 4 months, TeamWALT learned the ins and outs of designing, architecting, developing, and testing their app. TeamWALT imbedded a jr frontend developer in our team to skill up and learn our process for app creation.


TeamWALT was able to develop an app 80% faster than they could before. Their jr frontend developer also saw a 70% improvement in technical proficiency while creating Envie.

Through the training and processes with Sodium Halogen, TeamWALT can now build and maintain mobile apps.

“Working alongside SH has been a great experience. They are efficient, to the point and know what questions to ask and when to ask them. They are great at planning and giving visibility to the plan. Hopefully, this will blend into a future relationship on other projects.”
