Lead Enrichment
Articles and playbooks.

Every Zrevick article tagged Lead Enrichment — how founders turn AI-built products into companies that sell, market and support at scale.

Enrichment decides whether your outreach opens with insight or with a guess, and most teams overpay for data they never verify. This article reviews five Clay alternatives for teams that want the workflow without the credit-burning pricing, and along the way teaches the evaluation method that outlasts any vendor list: sample twenty records, count how many emails, titles and company sizes are still correct, and divide the cost by the contacts that survived. You will also see where enrichment quietly gets expensive, including credits burned on stale records, charges per field, and plans priced against volumes a small team will never reach. The deeper point: your own activity data (who visited, who replied, who opened) is often the richest signal you own, and the best systems combine it with third-party data instead of replacing it. Buy data you can verify.

Every article in this section is written for the same reader: a technical founder running sales, marketing and support with a team of one to ten, usually while Claude Code or Codex ships the product. New guides are filed under their topic as they publish, so this page grows rather than ages. If you are mid-decision, start with the most recent article; if you are new to the topic, start with the overview and work forward. Skim the summaries first, then commit to the pieces that match the workflow you are fixing this quarter.
