# Launch Cohort > Check a B2B SaaS marketplace's launch and co-marketing program - the operator side. Answer a short interview and > paste the partner roster and the launch claims drafted so far; the browser traces every vetted or curated claim to > the review gate and the apps it vetted, ranks the founding cohort, checks for one canonical embargo with kits before > the lift, and ranks featuring and co-marketing rationing under a published rule. Metered runs write the launch plan, > and the featuring and co-marketing program. Built on the SkillSafe skill @samber/app-marketplace-launch-marketing, > from samber/developer-platform-skills (MIT), by Samuel Berthe. https://launch-cohort.skillsafe.ai/ ## What is free - The cohort: a curated vetted cohort, a design-partner micro-cohort, a catalog migration or staggered waves, ranked by partner supply, the review gate, the date and the effort ceiling, with the moves shown. - The claims: every drafted launch claim marked backed or not - a vetting claim with no live gate, a count above the vetted roster, or a migrated catalog sold as curated fails. - The reveal and the program: one canonical embargo date, time and timezone with kits and pre-approved quotes; featuring (badges, editorial rotation, paid catalog) and rationing (tier ladder, invitation cohorts, priced catalog) ranked; paid placement labelled; a published allocation rule; demand gen for every partner. Plus an embargo notice, a roster CSV, the checks (.csv) and everything (.json). ## The metered lanes Two tasks on gpt-terra, metered per run, routed by `task`. Input string fields: `task` (launch or program), `operator`, `roster`, `carry` (program only: the launch decisions) and `facts`. - `launch` replies with `summary`, `cohort`, `claims`, `reveal`, `kit`, `kpis` and `caveats`. - `program` replies with `summary`, `featuring`, `placement`, `demand_gen`, `rationing`, `figures`, `starved`, `kpis` and `caveats`. The page holds every reply to its own facts: the ranked cohort, every unbacked claim rewritten, a canonical embargo on the flagship anchor, timed social posts and a full kit; the ranked featuring rung with published rules, labelled paid placement, the ranked rationing rule and where it is published, labelled figures and featuring lift baselined against a prior fortnight. ## Links - API tutorial: https://launch-cohort.skillsafe.ai/api.html - Source skill: https://skillsafe.ai/skill/@samber/app-marketplace-launch-marketing
