TierBoard
Community-ranked tech companies, built from anonymous head-to-head votes.
TierBoard turns an opinion that usually lives in group chats — which tech company carries more prestige? — into a live community ranking. Visitors vote anonymously in head-to-head matchups, and a Bradley-Terry model recomputes an order-independent leaderboard from the aggregate vote data.
The idea
Tech-company rankings are everywhere, but most are editorial lists or anecdotes with no visible method behind them. TierBoard narrows the question to one repeatable choice: given two companies, which one would you pick for prestige?
As more people answer that question, the product turns the crowd signal into a board that can move without anyone manually deciding the order.
How it works
Each anonymous matchup is recorded in Supabase, with shared rate limits protecting the voting endpoints. A Bradley-Terry model fits every company at once so the final ranking depends on the full vote set, not the order in which votes arrived.
The product pairs the voting flow with a searchable leaderboard, company tiers, movement indicators, sector filters, and a methodology page that makes the scoring model inspectable.
Engineering decisions
We kept voting account-free to make participation nearly frictionless, then handled abuse at the API boundary with server-side validation and Upstash-backed rate limiting. Ranking updates run in batches so the same set of votes always produces the same board.
That tradeoff gives up instant score movement in exchange for a result that is reproducible and easier to explain.
