Bespoke applications, mobile apps, and AI-powered tools — built carefully, launched for real, and designed to hold up.
We take ideas seriously. Then we build them.
Custom software designed around your exact problem. No off-the-shelf compromises, no generic templates. We scope it, build it, and stand behind it.
iOS and Android applications built with React Native. One codebase, both platforms, no shortcuts on quality — from prototype to App Store submission.
Intelligent applications powered by large language models. We build the product layer that makes AI actually useful to the people who need it.
MB & Co Ventures is a boutique software development firm founded by brothers Leib and Avi Menter. Small team, deliberate process, high standards. One of us writes the code. The other one approves it.

"Small team. High output.
Questionable division of labor."
