This is not a talent roster. It is a working directory of every engineer eligible to staff your next sprint — every GitHub handle, last shipped at, primary stack, and vetting percentile. Filterable. Inspectable. Publicly accountable. The same 140 names backing the first-sprint-or-free guarantee, now legible in plain English.

Pick your engineer before you book the call. The roster updates within an hour of any new contract.

HOW TO READ THIS PAGE →

Twelve cards. Five filters. One short answer per engineer.

Each card is a printed spec sheet, not a marketing blurb. We list what they shipped last, where, and on what commit cadence — because the founders hiring from this bench have already read enough polished resumes to know the difference.

Filter the directory below by stack, by last shipped at, by vetting percentile, by availability window, or by the YC / a16z / Sequoia companies they came from. The cards update live.

PRIMARY STACK → Full-stack TypeScript Go / Postgres Python / ML Swift / Kotlin Rust / Systems DevOps / SRE
LAST SHIPPED AT → Stripe alumni Shopify alumni Linear alumni Notion alumni YC W21–W24 a16z portfolio
VETTING PERCENTILE → Top 1% Top 2% Top 3–4.7% Lead-only
DEFINITION

“Top 4.7% of applicants” means a candidate cleared a four-stage funnel — application (1,200 words, no templates), paid 6-hour take-home on a real client-shaped problem, a live pairing session with a DaWabbit staff engineer, and a reference audit with two prior shipping leads. Of the 3,041 applicants we received in 2024, 143 cleared all four. The current bench holds the top 140.

DIRECTORY — 12 OF 140 →

The working roster.

VETTING FUNNEL — 2024 COHORT →

From 3,041 applicants to 140 names. The math, plainly.

No “world-class” claims. Four stages, four acceptance rates, four auditable numbers.

3,041 Applications received 1,200-word written application, no templates accepted.
418 Cleared the take-home A 6-hour paid build on a real client-shaped problem.
186 Passed live pairing 90-minute session with a DaWabbit staff engineer.
143 Cleared reference audit Two prior shipping leads, signed LoR, no exceptions.
4.7% Final acceptance rate · the active bench holds the top 140 of these 143. Of the 143 who cleared, 3 declined the offer terms. The current bench is the rest.
9.4 Average years of experience Median 9.1 yrs; nobody on the bench has fewer than 5 shipping years.
68% Leads who shipped at a YC / a16z / Sequoia company We don't ask where they interviewed. We ask what shipped.
— FROM THE FOUNDERS —

“We don't take resumes. We take commit graphs. If your last three years of public repos don't show a sustained cadence of merged work — reviewable, refactored, and reverted when wrong — you don't get past the first stage, no matter what you shipped for whom.

We reject three kinds of candidates on sight: the rockstar who can't explain their last outage, the architect who hasn't typed a PR in eighteen months, and the consultant who ships decks instead of artifacts. The bench is small on purpose. We make more money scaling the 140 than we would scaling to 1,400.

What we keep is the engineer who writes the postmortem, ships the rollback, and stays on Slack until the customer's customer is unblocked. The directory above is those people. No aliases, no stock photos, no padding.”

— H. Wong & M. Alvarez, co-founders DaWabbit Labs, Inc. · Founded 2019

— BOOK A SPRINT CALL —

Pick the engineer, not the agency.

You just scrolled twelve of the 140. On a 30-minute scoping call we'll match your stack, your deadline, and your timezone to two or three specific bench members — by name, by GitHub handle, by last shipped at. You pick. They sprint. You ship by day fourteen.

  • First commit in 58h median, verified via time-tracked GitHub audit logs.
  • 14-day artifact or the sprint is free. 312 sprints delivered, zero refund claims.
  • Weekly billing, no minimum. Used by 480+ startups to bridge fundraising gaps.
