We grade SEC filings in public, and evaluation work for the teams who build on them.
AITrailblazer runs DeltaSignal, a public SEC filing intelligence practice whose calls are graded on a public scoreboard, and an evaluation services practice that audits and builds benchmarks for SI systems that read financial documents.
Led by Constantine Vassilev, founder, who has built on neural networks and markets for three decades, with Rada Vassileva.
DeltaSignal Radar

Free. No paid tiers. No credit card. Watchlists and alerts are set up with our team after you reach out. Analytical content only, not investment advice. (c) 2026 AITrailblazer
