Turning Manual Lead Research into a Working Tool

A working internal MVP. No usage data yet.

Product Engineer  Optifeed  Ruby on Rails, Anthropic API  Built with Claude Code and Codex  2026

Problem

  • Lead research was manual. Finding companies, judging fit, and preparing first-outreach context took repeated effort.
  • Optifeed relied on inbound, founder-led sales, or manual research to find ICP-fit e-commerce brands.
  • Marketing needed a repeatable loop: create a project, run a search, get explainable candidates, and review them before any outreach.

The smallest useful loop

Not a GTM automation platform. Just this:

  1. Create. A project or campaign.
  2. Search. Run a lead-research search.
  3. Generate. Claude returns explainable company candidates.
  4. Review. Results are saved to the project page for marketing to review before any next step.

The project page: saved, explainable candidates, reviewed by people before any outreach.

What I did

  • Found the marketing problem, formed the hypothesis, and mapped the UX flow in Miro.
  • Scoped the direction with the CTO before committing to the MVP shape.
  • Built the MVP in Rails with the Anthropic API: project and search structure, saved results, and project-page views.
  • Used Claude Code and Codex for UI work and build support. How I use AI →

Four decisions

One project per campaign.

A repeatable structure, not one-off searches.

Explain every candidate.

Not a raw company list.

Keep the results.

Saved, not a temporary AI response.

People decide.

Marketing reviews before any automated action.

Where it stands

When my engagement ended, OptiGTM was a working internal MVP. I have no usage or adoption data.
