The human in the loop · Asked by a real engineer
Two letters, all over the app

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.

Radhakrishnan Selvaraj — RK
Radhakrishnan Selvaraj · RK

RK is Radhakrishnan Selvaraj. He built Proof and runs it — the product, the reading, the replies. Proof is built by Candor and Innovation.

The promise, with a face

“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.

The ledger

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.

The spine

Why Proof works this way.

AI screening résumés is the disease.You don't cure it by AI-screening logs. A human reads, or the promise means nothing.
A résumé is a claim. A dated log is proof.AI writes code now — the reasoning behind the work, in your voice, sustained, is the signal that's left.
Honest promises only.Proof gets you read. It never promises selection — anyone who does is selling something.
The books

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.

Silent Nods, Lost DollarsWhat silence costs a company — the felt-but-never-said gap that slips deadlines and loses clients.
Zero Maintenance TeamsThe team this product is named for — one that runs without constant firefighting because people say the real thing early.
The question behind the question

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.

Reach him
