How we calculate Trust Score
Every deal on GrabLTD has a Trust Score from 0 to 100. It's not a vibes-based rating — it's a weighted average of five measurable factors. The weights below are read directly from the algorithm, so this page and the breakdown on every deal card can never disagree.
Retention (our data) — 20%
Internal signalWhat percentage of GrabLTD buyers still have a tool in their vault 30 days after purchase. This is our moat — only we can compute it.
The five per-deal factors add up to 80% of the total weight. The remaining 20% is retention — the share of GrabLTD buyers who kept a tool 30 days after purchase. Today this defaults to 85% because we don't have a full data set yet. Once we do, the breakdown card on every deal will expand to show the real number.
We refresh the dev signals weekly from GitHub (commits in the last 30 days) and Twitter (last public tweet). Other factors (updates, support, refund, uptime) are scraped from changelogs, status pages, and refund policies. If a deal's trust signals are stale, the deal page still shows a useful neutral estimate rather than zero — we'd rather over-trust briefly than scare you away from a good tool.
Trust Score is one of three signals we use to rank deals. The other two are editorial picks (curated by us) and your own vault data (tools you've actually bought and used). When all three agree, the deal surfaces. When they disagree, the deal page shows you the disagreement so you can decide.
