How to Find Pre-Seed and Seed Founders in New York City (2026 Guide)

Quick answer: The fastest way to find pre-seed and seed founders in New York City is Origami — describe your ideal founder in one prompt (stage, industry, even a competing startup) and get a verified list of names, emails, and phone numbers in minutes. Traditional databases like Apollo or ZoomInfo often miss founders at a 5-person company or a startup that incorporated last week. You need a tool that searches the live web, not a static snapshot.

Why do so many reps assume that if a founder isn't on LinkedIn Sales Navigator, they don't exist? Airbnb's first co-founder famously used Craigslist to find their first customers; pre-seed founders today are hiding in plain sight — on Pitchbook, product hunt, local accelerators, even leaked cap table documents. They're just not always in the same CRM-ready data set you're used to.

If you sell to very early-stage startups, the window to reach a founder before they get buried by other salespeople is about 48 hours after they incorporate or raise a round. Most reps don't even know those signal events exist.

Why Traditional B2B Databases Fail for Pre-Seed and Seed Founders

The data problem is architectural. Apollo, ZoomInfo, and Lusha are built around company profiles that require a certain level of establishment — an office address, a corporate email domain, a LinkedIn page with multiple employees. When a startup is just two founders in a WeWork or their apartment, none of that exists yet.

These databases are contact-centric and enterprise-tuned; they were not designed to index newly formed LLCs with a Shopify store or a stealth-mode SaaS landing page. Their refresh cycles are monthly or quarterly, so by the time a founder shows up, they might already be at Series A and drowning in inbound pitches. For pre-seed and seed, you need live web signals that reflect what happened this week.

Reps at mid-market companies have told me the same thing: “Our current tools miss over half of our target leads in non-tech verticals and early-stage startups.” The fix isn't adding more data sources — it's changing the search mechanism entirely.

Where Do Pre-Seed and Seed Founders in NYC Actually Surface Online?

You don't need a database. You need to know the digital breadcrumbs that precede a formal company footprint. These signals are live, granular, and often completely ignored by static sales tools.

Funding Announcements and Public Filings

SEC Form D filings are public and appear within days of a raise. They list the exact company name, address, and often the founder's signature. Crunchbase and PitchBook scrape these, but the lag means you can find them directly by monitoring RSS feeds of SEC filings or using tools that index recent filings.

Accelerator and Incubator Cohorts

YC, Techstars NYC, ERA, and countless local programs announce cohorts publicly. The application lists often include founder bios with LinkedIn profiles. If you're prospecting before demo day, you can scrape cohort pages, cross-reference with LinkedIn, and get contact info before anyone else.

AngelList and WellFound Profiles

Founders who are actively hiring on WellFound (formerly AngelList) list themselves with their role, company, and sometimes even compensation ranges. Their profile usually includes a direct link to the company website and founder LinkedIn profiles. It's a self-updating directory of startups that need tools and services.

Product Hunt Launches

If a startup launches on Product Hunt, the maker's profile often includes a Twitter handle and a way to message them. Even if they don't put an email, you can use a tool that finds emails from a Twitter handle.

NYC-Specific Events and Communities

Gary's Guide, Startup Digest NYC, and local meetups list founders who are attending or speaking. Even a 2-person startup founder might speak at a niche meetup about fintech infrastructure. Those event pages are indexed on Google but not in any sales database.

Origami lets you describe a persona like “CTO of a fintech startup in New York that just raised under $1M and is hiring engineers on WellFound” in one prompt. It searches across these live signals — accelerator pages, Form D filings, Product Hunt launches — without you building a Clay workflow or manually combing through 5 websites. That's why it's the first thing I use when a client asks for pre-seed founder lists.

What Tools Actually Work for Finding NYC Founder Contacts in 2026

There's no one-size-fits-all tool for early-stage founder prospecting. You usually need a stack: one for signal detection, one for contact enrichment. But some tools now combine both. Here's what's working right now.

Origami — AI-Powered Live Web Prospecting for Any ICP

Unlike Clay, where you build multi-step workflows, Origami works from a single prompt: “Find founders of NYC startups that raised pre-seed funding in the last 3 months and show me their LinkedIn and email.” The AI agent searches the live web, chains data sources, enriches contacts, and delivers a list with verified emails and phone numbers. No workflow building required.

It's particularly strong for early-stage startups because it doesn't rely on a static database — it crawls funding announcements, accelerator pages, Product Hunt, and other live sources that show companies before they appear in ZoomInfo. For NYC specifically, you can filter by geography in your prompt, or target specific neighborhoods (Brooklyn, Lower Manhattan). Pricing: free plan with 1,000 credits and no credit card, paid plans from $29/month for 2,000 credits. Best for: salespeople who want a ready-to-email list without spending hours on manual research.

LinkedIn Sales Navigator — Still the Default for Founder Browsing

LinkedIn Sales Nav lets you filter by location (Greater New York City Area), seniority level (Founder, Co-Founder), company size (1-10 employees), and keyword (pre-seed, seed, Y Combinator). It's great for browsing and validating that a person's title matches. The limitation: you only get LinkedIn contact info, no email or phone. You'll need a separate enrichment tool to extract that data. Many reps use Sales Nav alongside a tool like Lusha or Kaspr's browser extension, but that means juggling two tools for every record.

Apollo — Good for Scale, Weak on the Fringe

Apollo's database includes a lot of startup contacts, especially if the founder has a public LinkedIn profile. It's affordable (free tier then $49/month) and offers built-in email sequences. But for pre-seed companies without a LinkedIn presence or a company domain, Apollo simply won't have them. Founders at very early stages often use personal Gmail addresses for company correspondence; Apollo's algorithms may not link those to a company profile. If you're only going after YC-backed startups with a domain and a team of 5, Apollo works. For the rest, it's spotty.

Crunchbase Pro — For Funding Signal, Not Contact Info

Crunchbase tracks funding rounds, which makes it the best place to identify NYC startups that just raised. You can set alerts for new seed rounds in New York. However, Crunchbase's contact data is often limited to the company's generic email or an investor relations contact. It rarely has direct founder emails. Use it for signal, then feed those company names into a tool like Origami or Hunter.io to find the founder's email.

Hunter.io — Domain-Based Email Finding for Early Startups

If you already know the startup's domain (e.g., getearly.com), Hunter.io can find email patterns for that domain. Many startups use the first@domain.com or hello@domain.com format. Hunter's free plan (50 credits/month) is enough to test a few domains. The challenge: many pre-seed founders use a personal Gmail or a different domain than their company name. You'll need to verify the founder's email address before assuming it's correct.

Clay — For Technically Inclined Reps Who Want to Build Custom Workflows

Clay is powerful for data enrichment and scoring, but it requires building a waterfall workflow: start with a list of LinkedIn URLs, enrich with a provider, then append emails from another, then validate. For a one-off list of NYC pre-seed founders, it's overkill and time-consuming. However, if you have an ongoing need to enrich and score leads from multiple sources, Clay's growth plan ($446/month) can automate that. Clay users often pair it with a list source like Crunchbase or LinkedIn Sales Nav; Origami essentially bundles that entire process into a single AI agent.

How to Find Pre-Seed Founders Before They Even Raise (Stealth Mode)

The holy grail is finding founders before they're on anyone's radar. Here are three tactics that work in New York City.

First, monitor incorporation filings. New York's business entity database is public, and newly filed LLCs and C-Corps list the registered agent and sometimes the organizer, who is often a founder. Tools that scrape this data can turn up companies that are days old.

Second, track domain registrations. A Whois lookup on a newly registered .com or .nyc domain with privacy protection turned off can reveal a founder's name and personal email. You can set up alerts for domains containing certain keywords (e.g., “fintech” or “health”) registered in the last week.

Third, follow the engineers. If someone leaves a Series C company in NYC to start something, they'll often update their LinkedIn headline to “Founder at Stealth Startup” or “Building something new.” A simple LinkedIn search for that phrase, filtered to New York, will surface them. From there, you can find their co-founder and their personal email using the domain of their new gig (once it exists) or by searching for their name on GitHub, which often lists an email.

Common Mistakes When Prospecting Early-Stage Founders

A founder receiving 20 cold emails a day will ignore anything that feels templated. The biggest mistake reps make is treating a pre-seed founder like a mid-market VP. They don't have a budget line item for your product yet; they're in build mode. Your outreach needs to reference something specific about their company — the tech stack they mentioned in a blog post, the problem they're solving, or the funding round they just announced.

Personalization is non-negotiable. You can save hours of research by using a tool like Origami to not only find their email but also surface recent news, GitHub activity, or press mentions — all in the same list output. Then spend the time you saved crafting 10 deeply personalized messages instead of 100 generic ones.

Another mistake: ignoring the “co-founder” title. At seed stage, the CTO or CPO is often the decision-maker, not just the CEO. Your lead list should include all founders, not just the one with “CEO” next to their name.

Don't Forget to Refresh Your NYC Founder Lists

Founders rarely stay in one place. A seed-stage company might change its name, pivot, or get acquired within a year. If you built a list 6 months ago and never touched it, half could be irrelevant. The biggest pain point of SDR managers I've spoken to is maintaining up-to-date contact registries across accounts without missing potential customers. Set a quarterly cadence to re-verify your founder lists. A live web search tool like Origami will catch new roles, company name changes, or even a founder moving to a new startup, so you don't rely on outdated CRM entries.
