LaunchCrew turns one product idea into launch content a solo founder can actually trust. The problem: generic AI invents claims, sounds like slop, and acts without approval, while the founder carries the liability for every word. Existing tools solve scheduling; none solve trust.

How it works: the owner confirms the product's facts once, each with a source, and unconfirmed claims cannot enter a draft. Three owner-defined agents then run in sequence on Muse Spark: Scout (skeptical analyst), Maker (brand voice writer), and Checker (strict auditor). The Checker pairs model review with deterministic fact checks, so a claim that conflicts with a confirmed fact is refused with the reason named, with no model involved in the verdict. Approval is bound to the exact reviewed version through a tamper-evident digest; any edit clears the approval and forces a full recheck. Approved content sits behind a Ready gate (approved pack, passing format checks, approved channel variants) before it can publish to a connected Instagram account, and the published result is verified afterward as a separate step. Every run ends in a receipt: model called, call and token counts, claims checked, verdicts.

The live site is public, no login, all features open: https://launchcrew.summitsingh.com. Proven live during the event: real Instagram posts published end to end through the Ready gate (Nov 3 and Nov 4), a Spark proof pass (3 live calls, receipt verified, seeded veto blocked), and a SAM 3.1 segmentation proof pass. All work was built new during the event, October 26 to November 4, 2026.
