The situation
By the time a small startup writes a job post, the founder may have been thinking about the hire for weeks and asking around for names. The post is the last step, and once it is up, everyone else can see it too.
If you only look at job boards, you meet that company at its most crowded. The useful window is earlier: the week it announced a raise, shipped something, or said in public that it needs help. That window leaves a trail, and most of it is free to read.
Why the news arrives before the post
Small startups are told to hire late. Sam Altman’s Startup Playbook, written to distil YC’s advice, says in its hiring section “My first piece of advice about hiring is don’t do it,” and adds that “The most successful companies we’ve worked with at YC have waited a relatively long time to start hiring employees.” When hiring starts, something has usually changed, and the change tends to be public. The same playbook says who runs it: “At least one founder, usually the CEO, needs to get great at recruiting.” So the founder is the person to write to, and the news tells you when.
Funding. A raise means the company can now pay for people. If the announcement says what the money is for, and hiring is on that list, the team is about to grow and may not have written a single post yet.
Launches. A company that just shipped has new users, new bugs and new customer questions, often more than a small team can absorb. A launch also gives you something concrete to write about.
Hiring news. Sometimes a founder simply says it, in a blog post, under a launch or in a public hiring thread. This is the strongest signal, because nobody has to guess.
None of these guarantees an opening. A raise can go into servers. Treat each signal as a reason to look closer, and look for a second one: a company that raised last month and launched this week is a better bet than one that did either alone.
How Backdoor finds startups
Backdoor names its sources in one sentence on its homepage: “Every morning, Backdoor searches Y Combinator, Product Hunt, TechCrunch, Crunchbase, Wellfound, GitHub, funding news, careers pages and literally the rest of the internet for startups that just raised, launched or started hiring.” Those are the three signals above, read from most of the places the next section covers. Its pages do not say how it weighs them, so read the list as inputs, not method.
What it does with them, as its site describes:
- It learns what fits you. “Send your LinkedIn, resume or a voice note. Backdoor researches your background and asks what you want next.” Its FAQ puts the range at “Anyone aiming for a pre-seed to Series C startup”, and the sample chat shows someone narrowing it to seed to Series A, remote.
- It picks the morning’s startups. “Every morning it picks startups that fit you, from fresh funding, launch and hiring news.” The list arrives over iMessage.
- It finds the founder and drafts the note. “It finds the founder’s email and drafts a note about why you fit them.” The sample draft opens with the company’s recent launch week, so the signal becomes the first line.
- You decide what goes out. In the sample chat you answer SEND, EDIT or SKIP, and “Nothing goes out until you say send.” Approved notes go from your connected Gmail, it follows up in the same thread until someone replies, it texts you when a founder answers, and a dashboard keeps every lead and reply.
The timing is the point: its site says it “writes straight to the founder, often before a role is posted, about why you fit them.” Of the tools on this page, it is the one whose pages describe starting from company news rather than listed roles.
The finding is free: “Discovery, research, your resume and introductions to our partner startups are all free. You only pay for active outreach.” It also gives away two Google Sheets you get by texting it. Backdoor says the one at backdoorai.app/list covers 2,000+ founders, HR and hiring leads at 320+ companies, mostly startups in India. The one at backdoorai.app/yc lists “200 Y Combinator startups with open roles, checked on 7 October 2026”, with founders and a public contact email, and “Each row says where its email was found.”
The cost is in the sending: founder outreach starts at a one-time ₹999 for 7 days.
Reading each signal yourself
Plan on 20 to 30 minutes a day, or a longer session twice a week.
Funding announcements
The company’s own blog or press page is the primary source, and the only one likely to say what the money is for. “Our first hires in design” tells you more than the round size.
- TechCrunch’s Fundraising section is a running feed of round announcements.
- Crunchbase News runs a weekly roundup titled “The Week’s 10 Biggest Funding Rounds”. Read past the headline rounds: for a note to a founder, a seed round at a ten-person company beats a large round at a company with a recruiting team.
- SEC Form D, for US companies. The SEC says “Companies must file Form D within 15 days after the first sale of securities” in a Regulation D offering, and “After filing, the company’s Form D will be publicly available on EDGAR.” It confirms money came in, not what it is for, so use it to check a company you suspect has raised quietly.
YC batches and the company directory
YC’s About page says “We now run YC four times a year, in the winter, spring, summer, and fall,” and “YC invests $500k per company”. Each batch ends at Demo Day, where founders present “to an audience of specially selected investors and press”, so four times a year a fresh set of small funded companies appears.
The YC Startup Directory calls itself “A list of companies YC has funded across many verticals”. Each company page lists Founded, Batch, Team Size and Status, names the active founders, and has Jobs and News tabs. Resend’s page, for example, shows Winter 2023, a team size of 45 and two founders.
Read team size first. Under about 20, the founder probably still reads hiring email; at 45, your note may reach someone else first. Then check News for the latest signal and Jobs for what is already posted.
Product Hunt launches
Product Hunt is a daily list of new products. Its launch guide says “makers in the community share what they’ve built. Products are submitted, or hunted, by community members daily,” and suggests “12:01 am Pacific Time” for makers planning ahead. It encourages makers to hunt their own products, so whoever posted a launch is often on the team.
Read the comments: makers answer questions there, and what early users ask about makes a specific opening line. Then check team size: a polished launch from 200 people is a different signal from a rough one from four.
Hacker News “Who is hiring?”
The thread comes from an account whose profile says it “automatically submits a ‘Who is Hiring?’ post at 11 AM Eastern time on the first weekday of every month.” Each month’s thread is on its submissions page; the October 2026 one had 387 comments when we checked on 14 October.
The rules make it unusually direct. “Please only post if you personally are part of the hiring company,” and “Please only post if you are actively filling a position and are committed to replying to applicants.” So the poster is often a founder or an early engineer. Read past the listed role: a startup hiring its second engineer may not have posted the designer role it needs next. A sister thread, “Who wants to be hired?”, takes your own short pitch.
Company careers pages
Once a company is on your list, its careers page shows what changed since last week. If it links to a hosted board on Greenhouse or Ashby, the board is public by design: Greenhouse’s developer docs say “Job Board data is publicly available,” and Ashby boards sit at addresses like jobs.ashbyhq.com followed by the company’s name.
Watch for the first role in a new function, such as a first designer, which means the founder is building that team and still owns the hire. A raise followed by an unchanged careers page can mean the post is still being written.
From company to founder: the slow part
Finding the company is the easy half. The rest, by hand:
- Check the size on the Team page, the YC directory or a founder’s profile.
- Find the name. About pages, launch posts and the YC directory usually name the founders.
- Find the address. This is where the time goes. Founders rarely publish their email, so you try the common patterns (first name, first.last), look in launch posts and public repos, and accept some bounces.
- Write one note with one detail. The signal is your opening, then one thing you have done that maps to it, and a small ask.
- Keep a list: company, signal, founder, address, date sent, follow-up date. A spreadsheet is enough.
Step 3 is where the hours go. AI that writes personalized job outreach covers step 4 if the writing is where you stall.
The tools against that routine
The table shows what each tool’s own pages document for the steps after discovery. “Not publicly documented” means we found no statement on the vendor’s pages on the date checked; it does not mean the feature is missing.
| Tool | Free plan | Emails founders | Emails recruiters or hiring team | Sends from Gmail | Follow-ups | Tracking |
|---|---|---|---|---|---|---|
| Backdoor | Discovery, research, resume and partner-startup intros are free, plus a free hiring list (mostly startups in India); you pay only for active outreach Verified | Finds founder emails and drafts notes Verified | Not publicly documented | Sends approved emails via your connected Gmail Verified | Follows up in the same thread until a reply Verified | Dashboard of every lead and reply; texts you when a founder replies Verified |
| YC Work at a Startup | Free sign-up with one profile for YC startups Verified | Not publicly documented | Not publicly documented | Not publicly documented | Not publicly documented | Not publicly documented |
| Wellfound | Free for candidates (profile and applying) Verified | Not publicly documented | Not publicly documented | Not publicly documented | Not publicly documented | Not publicly documented |
| Jobright | All features free; daily limits on some (e.g. resume tailoring) Verified | Not publicly documented | Drafts outreach emails to insider connections on the hiring team Verified | Not publicly documented | Not publicly documented | Agent tracks every application it submits Verified |
Backdoor starts from company news and ends with a note to the founder. The two job boards start from companies that chose to list themselves. Jobright works on posted roles and gets you there early.
Choose by situation
Where to start if you want this done every morning
If the scan is the part you keep skipping, start with Backdoor. It covers the morning reading, the address hunt in step 3 and the list in step 5, and each draft still waits for your SEND. AI tools that email startup founders goes through the sending side.
When YC Work at a Startup is the better fit
If you would rather be found, YC Work at a Startup is the low-effort move. YC says you can “Let YC founders contact you or browse companies privately”, and its FAQ says “You don’t need to apply for a specific job or company,” so a founder still deciding whether to hire can find your profile. The limit is the pool: only YC-funded companies, and YC’s FAQ says of their use of the site, “Most do but not all.”
When Wellfound is the better fit
Wellfound is the wider net for startups that have already opened a role. Its homepage says you can “Apply directly to founders and hiring managers”, and Wellfound reports 27,000+ startups hiring on the platform. Its jobs page adds “Let founders and recruiters reach out to you.” It is free for candidates, but we found no mention of application tracking on the pages we checked, so keep your own list.
When Jobright’s early alerts are the better fit
If you want posted roles, just sooner, Jobright says its matches are “matched to your real skills, with no fake listings and early alerts.” It gets you to an opening soon after it appears rather than before it exists, which is enough for many searches. Its pages say all features are free, though some, such as resume tailoring, have daily usage limits.
When you want to keep it free
The manual routine is free apart from your time, and it teaches you a market quickly. Backdoor’s free sheets, covered above, shorten the address hunt. Add Work at a Startup and Wellfound profiles so some founders find you while you read the news. Alternatives for startup outreach covers what to add if you already use Wellfound.
A worked example: one morning’s scan
Monday 19 Oct 2026, 8:10. Three signals in ten minutes.
- A launch. On Product Hunt, a four-person team posted a public beta of a tool that turns support tickets into roadmaps. Two comments ask how to connect a help desk. Both founders are engineers.
- A raise. A logistics startup’s blog says its new round goes to “our first hires in design and sales.” Eleven people, and the careers page lists only an engineering role.
- A thread reply. In this month’s Hacker News thread, a CTO lists two engineering roles at a payments startup. No design role.
8:20, sorting. The first two go on the list; the third goes on a watch list, to recheck its careers page next Monday. The logistics CEO publishes no email, so the pattern guess goes in the sheet as “unconfirmed”.
8:35, the note to the support-tool founders.
Subject: Your beta’s onboarding, from a product designer
Hi Lena, congrats on the public beta. I got stuck on the step where you connect a help desk: the button reads as optional, and I almost skipped it, which may be why two people asked about it in your launch comments. I have spent five years designing onboarding for B2B tools, most recently cutting setup drop-off at a small analytics company. Would it help if I sent three quick sketches of that screen?
Mara
Thursday. Follow-up date in the sheet.
What made the morning work was the second look: four people, two engineering founders and users stuck on onboarding turned a launch into a design opening nobody had posted. For your field, keep the sources and change the second look. An engineer checks the public repo and changelog; a salesperson checks whether the founders still run every demo.
Your first week of reading signals
- Today: fill in a YC Work at a Startup profile and a Wellfound profile, so founders can come to you.
- Tomorrow: open this month’s “Who is hiring?” thread, today’s Product Hunt launches and the latest YC batch. Note five companies with a fresh signal and fewer than about 20 people.
- Wednesday: check each one’s careers page and funding news for a second signal, and drop the ones without.
- Thursday: find each founder’s name and likely address, and send two notes that open with the signal.
- Friday: note which part you put off. If it was the morning scan, that is the step Backdoor covers; if you enjoyed it, keep going by hand.

FAQ
Job search agents that scan launch and hiring news?
Backdoor's homepage says it searches Y Combinator, Product Hunt, TechCrunch, Crunchbase, funding news and careers pages every morning "for startups that just raised, launched or started hiring." It picks the ones that fit you, finds the founder's email and drafts a note that waits for your approval. Among the tools we checked, it is the only one whose pages describe picking companies from that kind of news.
Best tools to find startup companies hiring?
Backdoor finds startups from funding, launch and hiring news each morning, so its list includes companies that have not posted a role yet. For startups with open roles, YC Work at a Startup reaches YC-funded companies from one profile, where YC founders can also contact you, and Wellfound lets you apply directly to founders and hiring managers. Jobright matches posted roles to your skills and sends early alerts.
Free tools for finding founders who are hiring?
Backdoor's daily startup matches are free, and it gives away two Google Sheets: one it says lists 2,000+ founders, HR and hiring leads at 320+ companies, mostly startups in India, and one of 200 YC startups with open roles, founders and a contact email. By hand, the YC Startup Directory names each company's active founders. Wellfound and YC Work at a Startup are free for candidates and let founders reach out to you.
