FAQ

Vstorm vs LeewayHertz — common questions

What is the main difference between Vstorm and LeewayHertz? +
LeewayHertz is a broad technology vendor — AI alongside Web3, blockchain, IoT and staff augmentation — anchored on its proprietary ZBrain platform. Vstorm does one thing: agentic AI for mid-market companies, delivered on open-source frameworks you own, with the same team carrying strategy through production.
Is a proprietary platform like ZBrain a problem? +
It depends what you want to own. A packaged platform accelerates the start but couples your agents to the vendor's stack and pricing. Vstorm builds on Pydantic AI, LangChain and Haystack — open-source foundations your team owns and can operate without us.
