PlanetScale Didn't Say Tin Is Fast. It Said '25× as Many Queries Per Second as ParadeDB' — Name Your Competitor, Publish the Number.

Real example · PlanetScale — Tin
Launched a GA full-text search extension for Postgres with named, checkable benchmarks against named competitors: "25× as many queries per second as ParadeDB" with "p99 latencies 26× lower," plus index build times (TIN "8m10s" vs Postgres GIN "2h09m04s") and concurrent-write throughput (TIN completing "270,279 updates" versus ParadeDB's 185,584 and pg_textsearch's 735)
See it yourself ↗tl;dr
PlanetScale didn't just claim Tin is fast. It named its competitors directly — ParadeDB, pg_textsearch, Postgres GIN — and published exact numbers across build time, queries per second, p99 latency, and concurrent-write throughput, including numbers where Tin didn't win outright.
The Play
PlanetScale didn't launch Tin by claiming it's fast. It launched by naming exactly who it's faster than, and by how much.
Why this matters
Developers have all seen a vendor benchmark that quietly picked the one metric where they won. That history means vague superiority claims get discounted by default, and technical buyers actively look for what's missing from the chart. Naming ParadeDB, pg_textsearch, and Postgres GIN directly — instead of "other solutions" — hands the reader something they can go test themselves. Publishing four separate benchmark dimensions instead of one, and including the dimension where Tin didn't come out ahead, signals the numbers weren't cherry-picked. And explaining the mechanism (using Postgres's own 'ctid' values as native document IDs instead of a separate mapping layer) gives an engineer a reason to believe the gap is real architecture, not a lucky test run.
How to run this play
1. Name your competitors directly in your own launch post instead of vague "other solutions" language — a specific multiplier against a named product is checkable, a superiority adjective is not
2. Benchmark across multiple dimensions, not just the one that flatters you — build time, throughput, latency, and write performance each carry independent weight with a technical buyer
3. Publish the number that doesn't favor you alongside the ones that do — an unflattering stat included on purpose reads as rigor, not as a fumble
4. Explain the actual technical mechanism behind the gap so a skeptical reader can judge plausibility, not just trust the chart
5. Open with the category-wide gap ("none of them met all of those requirements") before the numbers, so the benchmark reads as evidence for an unmet need rather than a comparison shopping page
Bottom line
The most persuasive benchmark isn't the biggest number, it's the one that names its competition, shows its work across more than one dimension, and doesn't hide the stat that didn't go its way.

How to apply this
- 1Name your competitors directly in your own launch post instead of vague "other solutions" language — "25× as many queries per second as ParadeDB" is checkable, "much faster than alternatives" is not
- 2Benchmark across multiple dimensions, not just one flattering number — index build time, queries per second, p99 latency, and concurrent-write throughput each tell a different part of the story
- 3Report the unflattering numbers too — Tin's index came out larger than pg_textsearch's (50.7 GB vs 41.5 GB) but PlanetScale published it anyway, because omitting one stat looks worse to technical readers than including it
- 4Explain the actual mechanism behind the performance gap (using Postgres `ctid` values as native document identifiers instead of a separate mapping structure) so engineers can judge whether the claim is architecturally plausible, not just take the number on faith
- 5Frame the launch around a category-wide gap first — "although there are at least three existing text-search indexes for Postgres already, none of them met all of those requirements" — before presenting your own numbers, so the benchmark reads as evidence for a real gap rather than a sales pitch
