Tessera - The Signal Foundry for Open Web

The intent-data industry sells $4.5B of signals every year, and only 26% convert — everyone buys from the same wholesalers and sees the same hot lead on the same Tuesday. Tessera flips it: stop buying signals, start building them from the long tail of the open web. Tessera scours eleven sources today and growing — SEC EDGAR, GitHub commit cadence, Wayback pricing-page diffs, podcast transcripts, Polymarket odds, regulator portals, career pages, Blind threads. Five cooperating agents (Collector, Normalizer, Investigator, Writer, Resolver) turn raw observations into time-stamped, citation-grounded events, then compose the brief. The differentiator: same data, any buyer. Pick a persona at the top — sales rep, hedge fund analyst, vendor risk officer — and Tessera re-ranks twenty public companies and rewrites the brief for that lens. Describe a new persona in one sentence and Tessera builds a Tessera-grade prompt around it on the fly. One Snowflake stack of twenty-three events reads as REACH OUT NOW · 91 for the sales rep, CONSTRUCTIVE · 82 for the hedge fund analyst, MONITOR · 62 for vendor risk, PASS · 18 for the VC scout. Same engine. Four decisions. Every brief carries a verdict (label, score, horizon, one-liner) and an executable agent task ready for human approval. Every claim cites the page it came from. Built on Bright Data's full stack: Web Unlocker for protected pages, SERP API for podcast discovery, Scraping Browser for JavaScript-rendered regulators, Web Scraper API as the routing layer, MCP Server as the agent harness — five products, each mapped to a specific job. Tessera doesn't predict the future yet. But it ships the cleanest open-web event substrate anyone has built to predict from.
