Enrichment That Pays For Itself
Cut the credit cost of a 1,000 row list by an order of magnitude without losing coverage, and diagnose an enrichment that silently returned nothing.
Someone burning credits faster than they expected, on lists that are not obviously better for it.

What this course costs
Work the examples on 100 row samples and the course costs very little. The whole point is that you finish it spending less per list than you do today.
What you will be able to do
- Build a column that only runs on rows meeting a condition, so cost scales with quality rather than volume.
- Write a custom research step in plain English that returns a consistent, filterable value.
- Diagnose an empty column: tell a skip from a miss, and a dependency race from a genuine failure.
Before you start
- Course 1.2. You need a real list with real columns to work on.
- A table of at least 200 rows, ideally one you already think is too expensive to enrich.
The lessons
- 1Website Finder first, always, and why everything depends on it5 min readA flat charge for every row it processes, so run it only on the rows that are missing a website. The figure is on the tool card.
- 2Conditions: run a column only on rows that qualify7 min readscreenshotsFree to set. Conditions are the thing that makes everything else cheap.
- 3The enrichment waterfall, and what charged on success really means6 min readFree to read. The habits it teaches lower every later bill.
- 4Build your own research step in plain English9 min readscreenshotsDepends on the research depth you choose. Preview on five rows before creating the column.
- 5Finding a value versus validating one, and when to reach for QA Agent7 min readCharged for every row it touches, because deciding something is false is the work. A fail costs the same as a pass. The tier you pick sets the price, and both are on the tool card.
- 6Not Found is not empty: the filter mistake that costs the most6 min readscreenshotsFree. This lesson saves credits rather than spending them.
- 7Let a column finish before the next one reads it5 min readFree. This is a sequencing habit, not a tool.
The build that proves it
The same list, an order of magnitude cheaper
Take a 1,000 row list you would previously have enriched flat. Rebuild it with Website Finder first, two conditional columns, a free scoring pass and a threshold, then the expensive enrichment on survivors only. Record the credits spent at each step.
- You have done it when
- Your final spend is under a fifth of the flat cost, and the number of usable rows at the end is the same or higher.
- Credit budget
- Work on a 100 row sample and multiply. Read each tool card before you create the column.
