SignalStack CF is a data clearinghouse that verifies and standardizes traction signals for crowdfunded startups across multiple platforms. Investors on SeedInvest, Wefunder, StartEngine, and Republic complain on Reddit and X that issuers’ self-reported traction is inconsistent, cherry-picked, or unauditable. SignalStack CF ingests read-only connections from Stripe, Shopify, app stores, Mixpanel, and accounting tools and outputs a canonical “Traction Factsheet” with cross-checked, anomaly-scored metrics. - Cross-platform verification (does revenue in bank feeds match claims in offering docs?). - Fraud/anomaly scoring using historical benchmarks for similar-stage crowdfunded companies. - Standardized metric taxonomy (ARR, GMV, NPS, CAC) so portals and aggregators can rank deals apples-to-apples. - An API+widget that portals embed to show “Verified by SignalStack” badges and drill-down charts. Revenue: B2B licensing to portals (per-listed-issuer) plus premium issuer plans that unlock deeper benchmarking and investor-facing narratives.
