About
Ciridae builds custom software for mid-market construction, field service and distribution firms, then runs and maintains it with the client. Pods of engineers and deployment strategists start with a three-day prototype on the client's data, then expand one workflow at a time on the firm's own platform, Crucible. Jack Soslow, a former a16z partner, and Jack Weissenberger founded it in January 2025. Fortune reported a $20M seed round led by Accel in May 2026. Named clients include Knight Commercial, Atom and DMD, quoted in one-line testimonials. The two case write-ups use changed names. One reports a 37% cut in days to collect. The firm reports a completed SOC 2 Type II audit.
