SquarePeg gives your ATS superpowers.

SquarePeg logo - a square peg dropping into a square hole beside the SquarePeg wordmark

The logo is the whole thesis in one image: a square peg finding its square hole. No forcing. No round-hole compromises. Just fit - measured, scored, and explained.

An AI-native recruiting platform that reads past the resume. SquarePeg enriches, evaluates and scores every candidate inside the tools recruiters already use - so lean teams can hire with confidence instead of keyword luck.

The Front Page

The reject pile was never a graveyard. It was a warehouse.

It is 9:14 on a Tuesday and a recruiter at a growth-stage company opens an inbox with 2,000 applicants in it. Somewhere in that pile is the person they will hire. Also in that pile: a few hundred keyword-perfect resumes that mean nothing, a handful of fabricated ones, and dozens of quietly excellent candidates whose resumes happen not to say the magic words. The old move is to skim, to filter, to trust the keyword search and hope. SquarePeg's move is different - it reads all 2,000 before the coffee cools, scores each one on genuine fit, and hands back a shortlist with the reasons attached.

That is the whole pitch, and it is refreshingly small. SquarePeg does not want to replace your applicant tracking system. It wants to sit on top of it and make it smarter overnight. Recruiters already live inside Greenhouse, Ashby, Lever, Workday. SquarePeg meets them there, as a single agent you can talk to, and quietly does the screening work that no human should have to do by hand.

Turn noisy, unstructured applicant data into recruiting intelligence that saves time and improves hiring outcomes.
SquarePeg - Company Mission

Founder and CEO Claire McTaggart did not arrive at this idea by accident. She spent years watching good candidates fall through the cracks of keyword filters - the square pegs that never found their square holes because a matching algorithm was looking for the wrong shape. SquarePeg began life as a two-sided job-matching marketplace measuring hundreds of signals beyond the resume: soft skills, behavior, preferences, incentives. The market taught a lesson, the product pivoted, and what survived is sharper: an intelligence layer that recruiters adopt because it lives where they already work.

What It Actually Does

Six jobs. One agent. Zero migration.

Ask it in plain language. It answers with scored candidates and the reasoning behind them.

01

Applicant Screening

Score unlimited applicants with confidence - surfacing top talent that keyword matching misses entirely.

02

Talent Rediscovery

Mine the candidates already sitting in your ATS to hire faster and cheaper, with no new sourcing spend.

03

Passive Sourcing

Reach passive candidates across 500M+ profiles using adaptable, role-specific criteria.

04

Fraud Detection

Filter fraudulent and ineligible applicants before they ever reach a recruiter's desk.

05

Data Enrichment

Infer skills and enrich resumes with company research for scalable, contextual evaluations.

06

Outcome Intelligence

Refine job requirements and predict hiring timelines using real data from your funnel.

Where the Hours Go

Screening is the tax lean teams pay to hire.

An illustrative look at how the work redistributes when an intelligence layer handles the grunt work. Directional, not audited.

Manual resume screening72%
Rediscovering past candidates9%
Sourcing passive talent14%
Actually talking to humans5%

The point of SquarePeg is to invert that top bar. When the machine reads the 2,000, the recruiter gets the 5% back - and the 5% is the part that only a human can do.

The Glass Box

A score you can't explain is a score nobody should trust.

Most AI in hiring is a black box: it says "yes" or "no" and dares you to argue. SquarePeg took the opposite bet. Every score arrives with the reasoning that produced it - what the model saw, what it inferred, why it ranked the way it did. The company calls it a glass box, and it backs the claim with continuous, independent assurance from Warden AI, which audits the models for bias on an ongoing basis rather than once at launch.

This is not a compliance footnote. In hiring, the whole game is trust - a recruiter has to defend a shortlist to a hiring manager, and a company has to defend its process to a regulator. Transparency is the feature that makes all the other features usable.

SquarePeg always provides strong candidates.

Marginalia

Things worth knowing.

The name

"Square peg in a round hole" - flipped. The logo is literally a square peg dropping into a square hole. Fit, not force.

The pivot

It began as a two-sided job-matching marketplace before becoming the AI layer that sits on top of the ATS.

The trial

The free trial hands you 2,000 credits - enough to score a full job's worth of applicants before paying a cent.

The interface

It's one chat-based agent, living inside the ATS you already open every morning. No new tab to forget about.
