Webhook latency is the difference between a useful signal and a dead alert. The engineering behind sub-second delivery: hot path, retries, slow endpoints.
The architecture behind 280M profiles, 60B signals, 5M sites, and 24-hour refresh: ingest, hot-path serve, decay, and the tradeoffs.
A field guide to reading the Orbit intent score from 1 to 100, what each band represents, and how to set thresholds that surface real buyers.
Suppression lists are how visitor ID respects opt-outs, customer exclusions, and compliance flags. Why they belong at the graph layer.
How a cross-site pixel network produces person-level intent: pixel observation, identity join, scoring, and why this beats licensed bid-stream feeds.
A week-by-week look at how Orbit catches buyers in the research phase, how early signals appear, and what thresholds surface genuine intent vs noise.
Intent decays in days, not weeks. A look at why Orbit runs a 24-hour refresh cycle, how the pipeline actually works, and what weekly refresh costs you.
A field-level teardown of how Orbit builds an intent topic, what a person-level signal contains, and what a score of 80 actually represents.
Accuracy, match rate, and completeness are different things. The methodology, failure modes, and how Leadpipe scored 8.7/10 in an independent test.
Intent from last quarter tells you nothing about today. Here is why Leadpipe refreshes every record every 24 hours, and what weekly and monthly refreshes miss.
The principles behind 280M verified profiles and 30-40%+ match rates: deterministic matching, first-party signals, daily refresh, build vs license.
What an MCP server is, why it matters for sales data, and how the Leadpipe MCP gives agents direct access to 27 tools across intent, visitor, and pixel data.
Most of the modern web renders via JavaScript. How a serious intent pipeline parses SPA pages, headless rendering tradeoffs, and what naive crawlers miss.
