How we built Becker PM/Kalshi Orderbook Feed (and why we shipped it externally)
The internal-tool phase
Becker PM/Kalshi Orderbook Feed didn't start as a product. It started as Empire internal data pipeline — an internal tool we built for our own customer apps. We needed it. We built it. It worked.
The "wait, others might want this" phase
After running Becker PM/Kalshi Orderbook Feed in production for months across multiple internal apps, the pattern became obvious: every team building similar workloads hits the same wall. The build-it-yourself path is 4-12 weeks of plumbing. The buy-it path costs 5-10x more than it should.
We had the engine. We had the runbook. We had the bug-fixes. The only step left was wrapping it in pricing pages and signup forms.
What changes when you ship externally
Three things changed when we exposed Becker PM/Kalshi Orderbook Feed as a product:
- Documentation got real. Internal Slack threads don't count as docs.
- Edge cases got prioritized. Single-tenant code makes assumptions that break the moment a second tenant arrives.
- Pricing got honest. No more "free internally" hand-waving.
What stayed the same
The engine. The code path that handles your request is the exact same code path serving our own apps. We don't ship a stripped-down "public" version. We ship the one we use.
