Our product

Metered billing for an AI blog engine

Blogger Dog auto-writes and publishes SEO posts straight into a GitHub repo. The prototype worked, but it couldn't charge a cent and the GitHub tokens lived in plain config.

Hardening a delivery marketplace for scale

A delivery-marketplace flow that strained under real traffic. We reworked the data flows, added observability, and stabilised the realtime layer so it held up under load.

Credit billing & guardrails for an AI tool

The humanizer worked, but every request cost money and nothing metered it. We shipped a credit system, Stripe checkout, and rate limits to keep usage sustainable.
