How to Find US Investors for European Pre-Seed Startups in 2026

Quick Answer: The fastest way to find US investors for European pre‑seed startups is Origami — describe your ICP in one prompt (e.g., “US micro‑VCs and angels who have funded European pre‑seed SaaS companies in the last 18 months”) and the AI agent searches the live web, enriches contacts, and verifies emails, giving you an outreach‑ready list in minutes. No more manual cross‑referencing between Crunchbase, LinkedIn, and AngelList.

If you’ve ever spent a Sunday evening clicking through Crunchbase profiles, scrolling AngelList, and then trying to find the email address of a partner who hasn’t updated their LinkedIn in years, you know the exact pain we’re talking about.

One fintech founder told us: “I keep getting lists full of generic ‘investors’ who turn out to be wealth managers or public‑market guys. They don’t write pre‑seed checks.” And when you’re building a startup, that kind of wasted outreach time isn’t just frustrating — it means you’re not actually talking to the 5 or 10 angels who could change your trajectory.

The problem is structural. Most databases (Apollo, ZoomInfo) categorize investors by firm, not by investment stage, geography, or recent activity. LinkedIn Sales Navigator can surface VCs, but it won’t tell you if they’ve ever funded a European startup — and it certainly doesn’t give you a verified email. So you end up using 3–4 tools, copying and pasting into spreadsheets, and still guessing whether the contact is relevant.

Why Are US Investors Interested in European Pre‑Seed?

US investors have been increasing their allocations to European pre‑seed for good reason: lower valuations, strong technical talent, and regulatory tailwinds in AI, climate, and deep tech. A 2025 report from Atomico found that US‑based funds participated in over 40% of European pre‑seed and seed rounds, up from 25% in 2021. This means your target list isn’t some obscure niche — it’s a large, addressable market of investors who actively want European deals.

But simply searching for “US VC” returns thousands of irrelevant results. You need to find the subset that: (a) invests at pre‑seed, (b) has explicitly funded European companies, (c) is still active, and (d) can be reached with a direct email, not just a general contact form.

Our customers in fundraising services report that traditional investor databases miss over half of the active angels they actually meet at pitch events. The data is stale because an angel’s focus changes every 6 months, and no static database can keep up.

The Tools Most Founders Use (and Where They Fall Short)

Most founders start with a combination of Crunchbase, AngelList, LinkedIn, and a spreadsheet. Here’s why that stack breaks down when you’re targeting US investors for European pre‑seed:

• Crunchbase lets you filter by investor type and location, but filtering by “pre‑seed” or “Europe” often pulls in funds that haven’t deployed capital in years. Contact data is limited to generic firm emails.
• AngelList is great for US‑based startups to connect with angels, but its European coverage is sparse, and you can’t export a list with verified personal emails.
• LinkedIn Sales Navigator excels at finding individual partners, but it doesn’t tell you their investment stage focus or portfolio geography. You’d still need to enrich the contacts manually.
• Apollo/ZoomInfo are built for sales, not fundraising. They’ll give you contacts at Andreessen Horowitz, but not the two‑person micro‑fund in Austin that backed three European SaaS startups in 2025.

A healthcare startup founder told us: “Apollo gave me contacts, but there was no way to bulk‑filter for investors who’d actually done a pre‑seed deal in Europe. I ended up with a list of managing directors at growth funds — completely useless.”

A head of partnerships at a European fintech described the manual gap: “We use Dripify for LinkedIn campaigns, but even that’s not tailored. If I want to find US investors who understand European embedded finance, I have to spend 20 minutes researching each one.”

How to Build a List That Actually Converts

Instead of starting with a broad database, you want to start with a precise description of your ideal investor and let the tool search the live web. The best results come when you specify:

• Investment stage: pre‑seed, seed, first‑check, etc.
• Geography focus: Europe, with a preference for US‑based investors.
• Sector: your exact niche (e.g., B2B marketplaces, developer tools, climate hardware).
• Recent activity: funded at least one European pre‑seed in the last 2 years.
• Firm type: micro‑VC, solo GP, angel syndicate, scout, or seed‑stage fund.

When you feed that into an AI‑native tool like Origami, the agent searches the live web for portfolio pages, news articles, SEC filings (for US firms), Crunchbase tables, and even Twitter/X bios to find investors who actually match. It then enriches each person with a verified email and LinkedIn profile, and lets you send personalized outreach from the same platform.

One of our users in proptech ran a prompt: “US‑based angels and micro‑VCs who have funded European pre‑seed climate tech startups.” In under an hour, Origami returned 80+ investors, each with a direct email and a note on which European startup they backed and when. “This would have taken me two weeks by hand,” he said.

5 Tools for Finding US Investors in European Pre‑Seed

Here’s a comparison of the most common approaches, including the AI‑first option that handles the entire workflow from search to verified contact list.

Tool	Free Plan	Starting Price	Best For	Main Limitation
Origami	Yes (1,000 credits, no CC)	Free, then $29/mo	AI‑powered search with live web crawling; builds a verified contact list + sequences from a single prompt.	Not a full CRM; you export to your own system.
LinkedIn Sales Navigator	No	$79.99/mo (annual)	Finding individual partners at VC firms; good for browsing portfolios.	No investment stage filter; no email enrichment. Requires manual research for each contact.
Crunchbase	Yes (basic)	$29/mo (Pro)	Firmographic data: funding rounds, investors, and portfolio companies.	Contact data is limited to firm‑wide emails; European pre‑seed filtering is blunt.
AngelList	Yes	Free for startups	Connecting with angels and syndicates. Good for warm intros.	Poor export capabilities; little European investor coverage outside major hubs.
Apollo	Yes (free credits)	$49/mo	Large B2B contact database; sequences for email outreach.	Designed for sales, not fundraising; struggles to identify micro‑funds and active angels.

Why Origami Is the Fastest Way to Build This List

Traditional databases are static; they record what an investor did at the last funding round announcement, which might be 6–12 months old. When a new angel syndicate launches in Austin or a solo GP in New York starts writing pre‑seed checks to European AI startups, that appears in blog posts, Twitter threads, and press releases weeks before any database is updated.

Origami’s live web crawling catches these signals in real time. In a single prompt, you can combine filters that would require 5 Clay workflows or an entire morning of manual scraping. The output is a target list with:

• Verified email addresses and phone numbers.
• LinkedIn profiles for each investor.
• Notes on why they match (e.g., “Funded [European startup] in March 2026”).

And because Origami includes a built‑in sequencer, you can send multi‑step email and LinkedIn outreach from the same place — no more hopping between Instantly and Sales Navigator. One SDR manager at a fundraising advisory firm put it this way: “It’s like soup to nuts. I don’t need to build anything. I just describe my perfect investor and hit go.”

A founder of a data pipeline company told us: “I don’t care about the how, I just have a number to hit and I want to hit it.” That’s exactly the ethos behind Origami — you give it the ICP, and the AI handles the complex data orchestration that other tools demand you build manually.

How a European Fintech Found 80+ US Angels in Two Hours

We worked with a European fintech that had raised a pre‑seed round and was looking to bring on a small group of US‑based angels with fintech expertise. They had tried a combination of LinkedIn Sales Navigator and a VA, but the VA couldn’t distinguish between a partner at a growth fund and an active angel.

Using Origami, they entered: “US‑based angel investors and solo GPs who have written pre‑seed checks into European open banking or embedded finance startups in the last three years. Exclude people who work at growth‑stage funds.”

The AI search returned 105 profiles. After automated enrichment, 92 had verified emails. The founder then used Origami’s built‑in sequencer to send a personalized email referencing the specific European company each investor had backed. Within 10 days, they had 7 meetings booked and 2 soft commitments.

That’s the difference between a generic lead list and a high‑signal prospect list — you’re not guessing who might be interested; you’re reaching out to people who have already signaled interest through their actual behavior.

Make Your Investor List Work for You

Finding US investors who are actually writing pre‑seed checks to European startups isn’t a database problem — it’s a research problem. The signal exists in real‑time web content, not in a static CRM. Start with a tool that does the research for you, and you’ll spend your time on outreach, not list scrubbing.
