B2D Core
A portfolio of usage-priced SaaS products.
We build small, usage-priced products around a shared philosophy: verify, don't execute. Where a provider promises compliance and the penalty is real, there is room for an independent layer that proves it was actually met.
Products
Messaging Antifraud Gateway
An open-source, self-hosted gateway that sits in front of your messaging API (Twilio today) and stops abusive traffic before it reaches your provider — rate limits, budgets, geoblocking, and signature validation, running entirely on your own infrastructure.
