Pre-Seed Angel Investors by Sector: Global List for Founders

Pre-seed angel investors around the world are individuals who back startups at the earliest fundraising stage, often before major revenue or institutional funding. They usually invest smaller checks, support founders with networks and advice, and focus on sectors they understand, including SaaS, AI, fintech, climate technology, and health.

Evalyze.ai helps founders move from broad investor research to a more focused shortlist using pitch deck analysis, investor discovery, and AI investor matching.

Upload your pitch deck, check your investor readiness, and match with Pre-seed investors.

Why Sector Fit Investors Matter More at Pre-Seed

Pre-seed is not just “early money.” It is usually the round where investors are buying founder-market fit, early product evidence, and a credible path to the next milestone.

That means your list has to be tighter. A fintech angel who writes $25K checks is not the same target as a climate infrastructure advisor connected to $2M+ checks.

Use the table below as a starting shortlist, then qualify each investor by five filters:

Before building your list, use a pre-seed fundraising checklist to check if your startup is ready for investor conversations.

Global Pre-Seed Investors By Sector

Use this sector-by-sector list to find pre-seed investors who match your startup. Each profile includes the investor’s geography, typical check range, and focus area so you can build a tighter shortlist before starting outreach.

AI, SaaS, Enterprise Software, and Developer Tools Pre-Seed Angel Investors

How to use this cluster:
If your startup is AI or SaaS, do not pitch the word “AI” as the edge. Investors now expect a clear answer to what is defensible. Carta reported that AI startups raised about 50% of pre-seed dollars in Q1 2026, making the category attractive but more crowded.

FinTech and Payments Pre-Seed Investors

How to use this cluster:
Fintech investors will look past the deck design quickly. They usually care about regulation, risk, trust, distribution, and who owns the customer relationship. If you are raising pre-seed for a payments product, your list should separate payments operators from general fintech angels.

ClimateTech, CleanTech, EnergyTech, and DeepTech Pre-Seed Investors

How to use this cluster:
Climate and deep tech founders need a different investor list from SaaS founders. The check sizes are often larger, diligence takes longer, and the proof points can include pilots, technical validation, regulatory progress, manufacturing readiness, or infrastructure partnerships.

Carta’s 2025 review also noted that SaaS remained the largest startup industry by cash raised, while hardware and biotech/pharma ranked second and third, respectively, among U.S.-based Carta startups. That supports a clear lesson for founders: investors are not only funding lightweight software at pre-seed.

Consumer Internet, E-commerce, and Marketplace Pre-Seed Angel Investors

How to use this cluster:
Consumer investors usually want proof that users care before the pitch becomes too financial. That can mean retention, repeat usage, marketplace liquidity, waitlist quality, referral behavior, purchase frequency, or a strong founder insight from the category.

Do not send the same email to a Klarna founder, a Slack Fund investor, and a marketplace angel. The thesis overlap may be real, but the reason they care will be different.

Health, Biotech, and Hospital Service Pre-Seed Angel Investors

How to use this cluster:
Health and biotech investors will usually ask harder diligence questions earlier. Expect questions around evidence, clinical workflow, regulation, data quality, reimbursement, procurement, and why the team can sell into a slow-moving system.

Generalist and Multi-Sector Pre-Seed Angel Investors

How to use this cluster:
Generalist investors are useful, but only if your pitch is specific. If an investor backs many categories, your job is to show why your startup fits their personal pattern: operator background, portfolio overlap, geography, check size, or network advantage.

How to Qualify a Pre-Seed Investor Before Outreach

A weak investor list is usually too large and too vague. A better list is smaller, scored, and sequenced.

Use this scoring model before adding an investor to your first outreach batch:

• Score 8-10: add to first outreach batch.

• Score 5-7: keep for second batch or warm intro search.

• Score below 5: save for later unless there is a personal connection.

Investor outreach is not a volume contest. For a serious pre-seed raise, build a working list of around 200 qualified investors, then contact roughly 80-120 during the active raise.

Split the list into dream leads, strong-fit funds, warm angels and operators, and solo GPs or micro-funds so you pitch each group in the right order.

How to use Evalyze Investor Discovery for this workflow

Inside the Evalyze dashboard, use Investor Discovery before you start writing cold emails.

Set these filters first:

1. Stage: Pre-seed

2. Investor type: Angel investor, operator angel, micro-fund, VC, scout, advisor

3. Sector: SaaS, AI, fintech, climate tech, e-commerce, health, biotech, deep tech, consumer internet

4. Geography: Your target market, investor location, or expansion market

5. Check size: Match the investor’s typical range to your round plan

Then build three lists:

A founder raising $750K for a B2B AI infrastructure product should not start with broad “AI investors.” They should filter for pre-seed, AI infrastructure, developer tools, and, if relevant, U.S. or Europe, and check sizes between $100K and $750K. That gives them a workable shortlist instead of a directory dump.

What to Prepare Before You Contact Pre-Seed Investors

A good investor list will not save a weak fundraising package. Before outreach, prepare the basics:

Build Your Pre-Seed Investor List With Evalyze AI

Finding pre-seed angel investors manually can eat days before you even know if they fit your round. Evalyze helps you turn that process into a focused fundraising workflow.

Inside your dashboard, you can use:

• Investor Discovery to filter investors by stage, sector, geography, check size, and investor type.

• AI Investor Matching to find investors who fit your startup profile.

• Pitch Deck Score (Startup Analyzer) to see how prepared your startup looks before outreach.

• AI Pitch Deck Coach to improve your story, ask, market slide, traction slide, and investor narrative.

• Automated Outreach tools to move from the investor list to campaign execution faster.

• Fundraising resources and coaching to help you prepare for meetings, objections, and follow-ups.

A better investor list will not guarantee replies. But it will stop you from wasting your best pitch on the wrong people.
