Sharp bettors don't lose from a shortage of picks.
They lose from a shortage of time.
Twelve browser tabs of research collapsed into a 90-second morning brief is a different product than another tipster account. Closeline is the harder one.
Who we are
Six operators out of NYC and Chicago. Two ex-traders, two quants, one designer, one platform engineer. We run books, we log CLV, we argue about Kelly sizing at dinner. Closeline is the product we wanted and couldn't buy.
What we built
A real-time signal engine (36 types, sub-200ms across 48 books), a drag-drop methodology canvas that runs your rules against our stream, and a bet log that grades every call against Pinnacle close. No picks. No locks. No confidence scores we invented.
Why we built it
Because every good bettor we know is one tool short of being a great one. The edge is real — the friction is the problem. We wired the tools together and got out of the way.
Built by people who track CLV.
