Sources and verification
- Shutdown
- Technical co-founder Chase Adams retrospectively confirms the company officially shut down on October 14, 2025 and Plumb had ended. October14 is the stated formal company ending day, not an independently established last customer-access day. The displayed October17,2025 is an explicitly inferred observation proxy for the co-founder’s dated retrospective confirmation of the end, not an asserted technical cutoff. Exact customer cutoff, hour and timezone are unverified. The technical co-founder’s October13,2025 original retrospective explicitly dates the public shutdown announcement to October8,2025. Its linked X post is inaccessible; the read evidence is the co-founder’s chronology (https://curiouslychase.com/startups/5-years-of-startup-learnings-at-murmur-labs/). The official public-beta post identifies an independent signup at useplumb.com, creators building and monetizing AI workflows, subscriber flow sites and end-user applications. The old Substack announcement now redirects to Substack and is not used as read closure evidence. CEO Aaron Dignan identifies Murmur Labs as the company behind the Plumb agentic workflow platform. The operator profile says Everywhere, US; the founder being based in New York does not prove company headquarters, so no location or coordinates are asserted. The later team move to Rocket Money is separate from the documented Plumb closure. Closure source
