Custom software development benefits


Retain clients

We have slowed down client attrition and helped grow the platforms’ client bases, leading to product acquisition by one of the leading industry players.


Improve performance

We have reduced response time and improved system reliability of our partners' products through implementing a serverless architecture and tripled their growth speed.


Unlock new opportunities

We brought an IoT hardware kit and software with zero experience to product release and 15+ team members within one year, which helped partners save hundreds of thousands of dollars annually.


Iterate fast
