We run it on ourselves first.
We build and run our own software, on our own servers. The engineering, search and answer-engine work we sell is the work these products run on. Each one has a public site, so you can check it for yourself.

Fax for Agents
A fax API, a hosted MCP server and SDKs so AI agents can send and receive faxes. Each send is quoted and authorized first, and every job ends with a receipt.
Live Tennis API
Professional tennis data for developers. ATP, WTA, Challenger and ITF over REST and WebSocket. There is a free plan, client libraries and an MCP server.
Synapse built each product listed here. JSB Holdings LLC, a Delaware company, sells them, and each product's own site names that company.
Why this is the portfolio
- Same stack
- What we recommend is what we run. The bill for a bad decision lands on us first.
- Same measurement
- First-party event data on our own servers, not a number a third-party script decided to report.
- No handover
- The people who wrote the software are the people who make it findable. Nothing crosses a wall.
And for clients
Client work is anonymised, and no client of ours is named on this site. References are available privately, with the client's agreement. How an engagement works.
