You've sent polished files to big companies and heard nothing back. YC-backed teams aren't grading on pedigree or logo density on your header. They're grading on whether bullet one proves you ship when the playbook doesn't exist yet.
Check your resume for free with the posting pasted in. You'll often see Python, React, or Postgres flagged as matched while shipped features and user outcomes never appear under a dated role. The fix isn't another Skills row. It's rewriting so founders see scope and proof in the first eight words under your current job.
Below is a six-step pass built for early teams: what they scan for, ordered edits, before/after pairs you can paste, two edge cases, and a copy-paste bullet skeleton. Job searching is draining. This page is about changing lines on the page, not pep talks.
Quick Wins
- Highlight three must-haves from the posting before you touch formatting.
- Rewrite bullet one so scope, stack, and outcome share one line.
- Move your strongest side project into a dated block with two bullets.
- Export a single-column PDF and read it in Notepad before you upload.
What founders scan for on a YC startup resume
Most generic advice tells you to list every tool you've touched. Early hiring managers and parsers in Greenhouse, Lever, and Ashby weight dated Experience bullets higher than a Skills cloud. They search for proof you changed a product surface, not that you once opened a repo.
The bar your file is scored against: bullet one names scope (users, services, or revenue band), names the stack when the posting asks for it, and ends with an outcome a founder can ctrl-f: activation, retention, latency, cycle time, or support volume.
A composite engineer whose top bullet still reads worked on backend features loses to a file that opens with shipped billing webhooks on Node and Postgres, cutting failed payments 22% in six weeks for a 4k-user B2B SaaS. Same person. Different emphasis order.
Product and growth reqs search activation and experiment velocity. Platform reqs search reliability and deploy safety. Operator reqs search process you built from zero. Pull phrases from the specific ad tonight, not a generic startup word cloud.
I've screened YC and seed-stage files in Greenhouse where every tool from the posting sat in Skills while bullet one still said supported product development. The parser sometimes matched. The founder never saw proof you owned a shipped outcome end to end.
Keep the file to one page when you can. Founders often read between standups. If your strongest shipped win sits on page two, it might as well not exist. When in doubt, cut an older employer to a single title line and give the space to bullet one on your current role.
Read impact-first resume bullets US hiring teams prefer for the general placement rule. This page applies it to early-stage teams that hire fast and read on phones.
How to write a resume for YC startups in six steps
Work the steps in order. Each one changes what a founder sees in the first pass. Skip ahead to formatting and you'll polish a file that still hides the metric in bullet four.
Step 1: Pull scope from the posting and product page
Open the job ad and the startup's landing page in two tabs. Highlight three must-have skills and one outcome phrase: activation, infra scale, sales pipeline, or support load. Write those four items at the top of a scratch doc. Every edit tonight serves that list.
Note whether the team sells to developers, operators, or consumers. That choice changes which metric belongs in bullet one. Dev tools lead with integration count or API traffic. Consumer apps lead with retention or conversion. B2B leads with pipeline or logo count you can defend.
Step 2: Write a headline that mirrors the role
Replace a bare name header with role plus scope. Full-Stack Engineer, B2B SaaS, payments and onboarding beats Software Engineer with no context. Founders ctrl-f the role string from the posting. Give them an exact match without inventing a title you never held.
Before: Jane Doe, Software Engineer.
After: Jane Doe · Full-Stack Engineer (B2B SaaS, onboarding and billing) · San Francisco, CA · [email protected]
Step 3: Rewrite bullet one under each recent job
List roles in reverse chronological order. Under your current job, rewrite bullet one so the first eight words carry scope and outcome. Use four to six bullets on the current role and three to four on older ones. Lead with shipped work, not duties.
Before: Worked on backend services using Python and PostgreSQL.
After: Built Stripe webhook handlers in Python and PostgreSQL for a 4k-seat B2B app; cut failed renewals 22% in six weeks by idempotent retry logic and dead-letter queues.
Before: Managed marketing campaigns across channels.
After: Ran paid and lifecycle tests for a seed-stage fintech; lifted trial-to-paid conversion from 11% to 16% in eight weeks using onboarding email splits and in-app nudges tracked in Mixpanel.
Step 4: Move side projects into dated lines
If you built a tool, app, or open-source library that proves the posting skill, give it a title line and Month Year dates. Two bullets. Parsers and founders treat it like Experience when dates and outcomes are present.
Before: Side projects listed under Skills: personal SaaS, CLI tool.
After: Founder, Invoice CLI (Side Project) · Jan 2024 to Present · Shipped a Stripe-backed invoicing CLI used by 140 freelancers; reduced average invoice send time from 12 minutes to under 90 seconds via templated PDF generation.
Step 5: Format as a single-column PDF
Export one column, 11-point Calibri or Arial, Month Year dates, standard headers. No icons, no tables, no text boxes. Two-column templates scramble employer order in Greenhouse imports so your best bullet lands under Education.
Save as PDF unless the posting requests DOCX. Some portals re-parse DOCX more cleanly, but PDF is the safe default for founder-forward roles when the posting is silent.
Step 6: Verify keywords land in Experience
Paste the exported PDF text into Notepad or Preview search. Posting terms should appear inside dated bullets, not only in Skills. If Postgres only lives in Skills, move it into the bullet where you changed query latency or data model shape.
Read resume keyword placement skills vs experience when the checker flags matches that never show up under a job title.
Copy-paste YC startup bullet skeleton
"[Verb] [scope: users, seats, or services] with [stack from posting]; [outcome metric: activation, retention, latency, revenue proxy, or cycle time] by [specific change you shipped]."
Example fill: "Shipped onboarding checklist in React and Node for a 2k-user dev-tool beta; raised week-one activation from 34% to 51% by cutting setup steps from nine to four and adding in-app sample data."
Edge case: enterprise background moving into a YC startup
You don't need to hide the big-company logo. You need to translate scope into startup units. Replace internal program names with user or revenue proxies you can explain on a call. Show you operated with small teams and short cycles, not only governance committees.
Before: Led cross-functional initiative for internal tooling platform.
After: Led a six-person squad shipping internal API gateway features used by 800 engineers; cut partner onboarding time from three weeks to four days by replacing ticket-driven config with self-serve Terraform modules.
Edge case: new grad or bootcamp with thin paid history
Stack internships, contract work, and relevant projects as dated blocks. One strong project with users beats three course assignments with no outcome. Put the project with traction in bullet one on the page, not at the bottom of Skills.
Before: Relevant coursework: algorithms, databases, web development.
After: Software Engineering Intern, Harbor Analytics · Jun 2025 to Aug 2025 · Built Flask ETL jobs ingesting 2M rows nightly; reduced manual CSV uploads 90% for a three-person analytics team.
Lines that die before the founder reaches bullet two
Skills clouds without shipped proof. React, Node, Postgres, Docker, AWS stacked in Skills while Experience only says contributed to platform features is the most common gap on seed screens. Scanners sometimes pass. Founders ctrl-f for users and find nothing.
Buzzword summaries. Passionate engineer excited about fast-paced environments tells me you read a template. One line with role, scope, and a metric beats a paragraph of adjectives.
Responsibility verbs without numbers. Responsible for, assisted with, and helped with hide ownership. Founders hire people who ship. Write built, shipped, reduced, or grew with a scope noun and a defensible metric.
Logo padding unrelated to the role. Every brand on the page should connect to a bullet that maps to this posting. A famous employer name with no relevant outcome wastes the first screen.
Two-page files with no reason. Under ten years of relevant shipped work, page two rarely gets read on a phone screen between investor calls. Cut older roles to title-only lines if you need room.
Identical bullets sent to every startup. Founders can tell when bullet one ignores their product surface. Swap the metric emphasis and stack echo to match each posting, even when your history is unchanged.
AI-generated walls of text. Uniform bullet length, perfect grammar, and no rough edges can read synthetic on a founder screen. Keep your voice plain. Short sentences mixed with longer ones. Numbers you can defend on a reference call.
Missing link or GitHub when the posting asks. Engineers and designers should put one link near the header when the ad requests work samples. Don't bury it in Skills. Founders click when the rest of the file already shows shipped scope.
Run your YC resume against the posting
After the six steps, paste the same PDF against the req on your screen. You're checking whether activation, Postgres, or experiment language appears inside dated bullets, not only in Skills. Must-haves from the posting should match parsed Experience text.
When a stack term still misses, add it to the role where you shipped the feature, not as a twelfth Skills comma. When the portal marks cover letter optional, skip it unless the founder asked for one. When they ask, generate a cover letter that repeats the same shipped metric from bullet one.
Run a free ATS check with the description pasted before you upload to Greenhouse or Lever tonight.
Ship the one-page file tonight
When you need to know how to write a resume for YC startups, the sequence is simple: pull three must-haves from the posting, rewrite bullet one with scope and a metric, date your side projects, export a single-column PDF, and verify keywords sit in Experience.
Open the req tonight. Change bullet one first. Move stack terms out of Skills-only rows. Run a free ATS check before you upload again. This won't fix applying to staff roles when your scope was intern-level. It does stop qualified builders from losing to a footer full of tools while the shipped feature sat in bullet five.
And if you're targeting both platform and product reqs this week, fork the file. Latency and deploy safety lead for infra ads. Activation and experiment velocity lead for growth ads. Same history, different bullet one.

Frequently asked questions
Default to one page unless you have ten or more years of directly relevant shipped work. Founders and early hiring managers read on phones between meetings. A dense one-page file with four strong bullets per recent role beats a two-page timeline where bullet five finally shows the metric. If you must use two pages, page one must carry every outcome you'd want a founder to see without scrolling.
Many early teams skip them when Greenhouse or Lever marks the field optional. When a founder asks for one, keep it to three short paragraphs and repeat the same shipped metric from bullet one on your resume. Never paste a generic letter that could apply to any seed company. Match the product surface and the ambiguity level in the posting.
Treat real side projects like jobs when they prove the skill the posting needs. Give each project a title line, Month Year dates, and two bullets with scope and outcome. Do not bury a live SaaS with paying users under a Skills comma. Founders hire people who ship outside the job description when the work is relevant.
List only tools you can defend in a dated bullet. Eight languages in Skills with no repo, feature, or user outcome in Experience reads like a tutorial list. Put the stack inside bullet one first, then echo it once in Skills after it appears under a role. Parsers and founders both weight Experience lines higher than a footer cloud.
No for most YC applications that route through Greenhouse, Lever, or Ashby. Sidebars scramble employer order on import so your best shipped bullet lands under Education. Use a single-column PDF, 11-point Calibri or Arial, Month Year dates, and standard section headers. Save design energy for the words, not the layout.
