Named by the founder, without a confirmed workflow.
How it works
How we review tools.
We focus on tools that help earn traffic, produce stronger content, distribute it, or audit performance. Pricing, limitations, and source quality stay visible on every profile.
Three source signals
The source describes a concrete workflow, not just a product name.
The founder connected the workflow to an outcome; causality remains unverified.
How much to trust a source
Every background source carries a weight. Most of this catalog is the vendor talking about itself, and the label says so rather than hiding it.
- Strong.Quantified, and either independently reported or specific enough to check.
- Directional.Quantified, but self-reported or unverified. Useful for direction, not proof.
- Biased but useful.The seller, or someone paid by them, published it. Good for capability and pricing, weak for outcomes.
- Fit signal.Tells you who a tool suits, not what it achieved.
- Opinionated.A review, comparison, or take.
- Anecdotal.A single unverified report with nothing else to lean on.
Source rules
- Use the original.Link the interview and exact timestamp.
- Keep attribution clear.Usage, performance figures, and results remain attributed to their source.
- Preserve context.Record the workflow, its limitation, and any commercial relationship around the source.
- Exclude editorial claims.Sponsor mentions, host narration, and editor overlays do not become founder evidence.
Commercial relationships stay separate
Affiliate, partner, and sponsored labels never increase an evidence status or ranking.
Commercial links receive an adjacent disclosure and rel="sponsored";
normal official links do not.
One source, two useful views
Founder’s List curates founder profiles, interviews, and stacks. cost.tools connects that verified workflow evidence directly to software evaluations and cost comparisons.
