Who is RK?
These two letters are everywhere on Proof — replying on entries, answering in the FAQ, signing the bottom of pages. An engineer finally asked, right from his log: “who is RK? I feel maybe I missed somewhere.” Fair question. This page is the answer.

RK is Radhakrishnan Selvaraj. He built Proof and runs it — the product, the reading, the replies. Proof is built by Candor and Innovation.
“A human reads it.”
He is that human.
Not a metaphor, not a model, not a screening pipeline. The same person who built the app reads what you wrote in it.
Live from the database, this minute — not marketing numbers.
What he does with your words.
Every line below is a promise the app already keeps — this page just puts a name to who keeps it.
- Reads every engineer who writesNot a sample, not a dashboard — the entries themselves. Ten structured days read in minutes.
- Writes back on your entryAsk him a question when you log and the answer appears on that entry, where you wrote it.
- Curates the standoutsThe entries on /sample are his picks — and your name appears only with your explicit yes.
- Keeps your private notes privateA note to RK is read by RK. It never reaches your team, your founder, or anyone else.
- Never edits your wordsNobody can — entries lock the next morning. He reads the record; he doesn't touch it.
Why Proof works this way.
He wrote the books on this.
Not a side project — two published books on why teams where people speak up win, built into a product.
Can one person read everyone?
Today, yes — the ten-day filter does most of the work (most signups never cross it), and structured entries read in minutes. He isn’t the only reader either: founders and engineering leaders read the pool directly when hiring. If one reader ever isn’t enough, the answer is more human readers — never an AI screen.
The fastest way: ask on any entry when you log — he writes back there. Or email rk@candorandinnovation.com. Good questions end up on /faq — including the one that created this page.
