EXUMA LABS — Venture studio & dev shop
Factslane, Checker, PT Builder — our own products live in production and the App Store. The same engine builds yours.
01 — Our bets
We don't have a case-study slideshow. We have URLs you can open right now, and an app on the App Store you can install in two taps. Below: the bets we made on ourselves.
Web platform
A news reader engineered around credibility and signal. Multiple fetchers, evaluator pipelines, an idempotent backfill, and a turbulence index that flags volatile stories before humans do.
AI product
A claim-verification tool that walks an assertion back to its sources. Built on the same backbone that powers Factslane; tuned for journalists and researchers who'd rather see receipts than promises.
02 — Also built
Shorter bets, same engineering.
Native companion app. Push notifications, offline reads, the same feed in your pocket.
Open
A presentation-template builder for Sciencecast. Researchers compose, the platform renders.
Open
A focused GPT that demonstrates how a single, well-tuned prompt beats a sprawling chatbot.
Open
A no-nonsense domain lookup tool. A small thing done with care, kept up since 2024.
Open03 — What we do
Evaluator pipelines, fetcher provenance, cost guardrails, fallbacks for when the model is down. The boring engineering around the impressive demo.
Native and cross-platform. Push, offline, deep links, App Store review survival. Shipped Factslane iOS ourselves — id6749233867 if you want proof.
Rails, Node, the boring choices. Background jobs, idempotent backfills, deployments you can revert without panic. Docker Swarm in prod since day one.
Chat, voice, custom GPTs. Wired to outcomes — tickets resolved, leads qualified, hours saved — not to vibes or vanity uptime.
04 — How we work
We don't write thirty-page proposals. We write code. By the end of week three you have a working slice in your hands, and we have an honest answer about whether to keep going.
A clickable demo of the riskiest screen, plus a one-page architecture sketch. You see direction before you sign anything bigger.
Deliverable: clickable demo + arch sketch
One real feature, end to end, in production. Auth, data, deploy, the parts that bite. If we can ship one slice cleanly, we can ship the rest.
Deliverable: one feature live in prod
A written plan for the rest, or an honest no-go. We've turned down work because the fit wasn't there — we'd rather do that in week three than month nine.
Deliverable: ship plan or honest no-go
