Readiness — reflects technical quality, deployment requirements, operational autonomy, and available evidence. Bars show each score.
Product maturity — Prototype → Deployment-tested → Production-ready → Proven in use. Assigned from objective criteria; deployment method is shown separately.
Maintenance — the plan recommended after the 30-day defect coverage. Maintenance risk — estimated exposure to third-party API, platform, and infrastructure changes.
+ GTM — includes a go-to-market playbook for the niche. The playbook opens after purchase.

What “verified” means here
Every card separates three kinds of information. You always see which is which.Independently verifiedChecked by BigFish: the software deploys from a clean environment, the license and rights allow commercial use, and the capabilities on the card run as described.
Seller-provided evidenceLogs, invoices, recordings and usage history the seller submitted. Reviewed for consistency, not reproduced by BigFish.
BigFish estimateReadiness scores, operating cost, maintenance risk and time to deploy. Expert estimates based on the evidence above — not guarantees.
Am I buying an existing business?No. You're licensing software that can power a new business or improve an existing one. Customers, revenue, and business results are not included unless explicitly stated.
Do I own the software after purchase?You receive a perpetual, non-exclusive commercial license and the included source code. The original rights holder retains ownership and may license the same software to other buyers.
