How Termina Built the 2026 Seed 100 and Seed 40 Lists: Methodology, Metrics, and What It Means for B2B Founders

If you’re a founder raising your first round or a VC scouting for breakout signals, the Termina Seed 100 and Seed 40 lists are your cheat sheet to the world’s most effective seed investors. But how does Termina—the data engine behind Business Insider’s annual ranking—actually separate the top-tier from the crowded field? In this exclusive deep dive, we reveal the full process used to build the 2026 lists, including the 25 success attributes tracked, the updated weighting of recent investments, and the massive AI tailwind that reshaped this year’s results.

The Big Picture: Six Years of Seed Data, One Clear Trend

This is the sixth year Termina has partnered with Business Insider to produce the Seed 100 and Seed 40 lists. What started as a straightforward ranking of exits and follow-on rounds has evolved into a sophisticated predictive model. The 2026 edition marks a clear inflection point: AI has become the defining characteristic of seed-stage startups, and that shift is now baked into the methodology.

“AI has emerged as a defining characteristic of seed-stage startups today, with results that will likely drive the rankings for years to come,” the Termina team notes in their internal analysis. Investors with a prior AI footprint saw a significant boost in their scores this year—a trend that will only intensify as generative AI startups mature toward liquidity events.

The Candidate Pool: 1,974 Investors, Up 5% YoY

Termina began with raw data on 1,974 seed investors—a 5% increase from last year’s pool. That growth alone signals a booming early-stage market. The candidate universe includes:

• Active investors only – must have made at least five investments between 2011 and 2026.
• Global reach – includes solo VCs and angel investors from anywhere in the world, but assessed specifically on their investments in US companies.
• Diversity uptick – women now represent 11% of all seed investors in scope, an 8% increase since the first Seed 100 was published in 2021.

The Core Methodology: 25 Success Attributes Evaluated

Termina doesn’t rely on a single metric. They statistically analyzed investor performance across 25 distinct attributes using data from Crunchbase and PitchBook—plus direct track record submissions via a public form.

The Three Pillars of the Termina Score

While all 25 attributes feed into the final score, they fall into three critical categories:

1. Exits (Highest Weight) – IPOs and acquisitions are the most powerful differentiators among seed investors. A successful exit isn’t just a liquidation event; Termina requires that exits are “meaningfully above liquidation preference” or that they demonstrate increased company value beyond mere capital raising.

2. Intermediate Success Signals – Seed investments that consistently receive “material sums” of follow-on funding are treated as leading indicators of future success. Importantly, Termina updated its methodology this year to weigh more recent investments more heavily for these intermediate milestones.

3. Continued Activity – Past glory doesn’t cut it. “Great investments 10 years ago will not carry an investor into the list if they are no longer active,” Termina states. Investors must be actively deploying capital to remain eligible.

Why Exits Dominate the Rankings

Exits—whether IPOs or acquisitions—have the strongest statistical correlation with investor differentiation. Think of it as the single best proxy for judgment: an investor who backed a company that eventually went public or was acquired above liquidation preference has demonstrated exceptional pattern recognition.

That’s especially relevant for B2B founders. In our space, a “quiet” acquisition by a strategic buyer (think a CRM platform acquiring a sales intelligence tool) can matter just as much as a blockbuster IPO. Termina’s methodology captures both.

The AI Factor: How It Rewrote the 2026 Rankings

The 2026 list reveals a clear and intentional signal: investors with an existing AI footprint benefited significantly in their rankings this year. This isn’t accidental—it’s a design choice.

“Investors with a previous AI footprint have benefited significantly in their rankings this year,” the methodology paper confirms. That means:

• Founders building AI-native products should prioritize investors who have backed AI companies before—they’re statistically more likely to earn a high Termina score.
• Non-AI investors who want to climb the ranks in future years need to build exposure to AI deals now, given the “results that will likely drive the rankings for years to come.”

What B2B Founders Should Watch

For revenue teams and GTM leaders, this AI tilt matters because it’s reshaping which investors have the most influence at the seed stage. If you’re a sales tech or marketing analytics startup, having a top-ranked AI-savvy investor on your cap table signals to future Series A VCs that your company has high “liquidity potential.”

Who Made the Cut? (And Who Didn’t)

The final 2026 Seed 100 list includes:

• 22 investors who increased their rank from the previous year.
• 30 investors who held the same rank or maintained their position.
• The remaining 48 are either new entrants or moved down in rank.

Why Some Investors Didn’t Make It

Not everyone in the candidate pool qualifies. Key disqualifiers include:

• Insufficient activity – fewer than five total investments in the 2011–2026 window.
• Inactive status – no recent deals or a lack of ongoing portfolio management.
• Weak exit history – exits that were below liquidation preference, or no exits at all despite significant follow-on funding.
• Geographic mismatch – investments made outside the US are not counted in this rank.

How Termina Uses Direct Submissions (and Why You Should Care)

The methodology isn’t purely black-box. Termina accepts direct track record submissions via a public form. This is a smart move for two reasons:

• Data completeness – Crunchbase and PitchBook can miss early-stage deals, especially for solo angels or smaller micro-funds.
• Self-selection – the most confident investors will submit their own data, which often reveals hidden gems.

If you’re an LP or a founder researching potential seed investors, the presence of an investor on the Seed 100 (without needing to submit their own data) suggests their portfolio is strong enough to be picked up by public databases.

Practical Takeaways for B2B GTM Leaders

You’re not just reading this for trivia. Here’s how to use this methodology to your advantage:

For Founders Raising Seed Rounds

• Target AI-experienced seed investors – they’re statistically more likely to rank highly and to have deep networks for follow-on capital.
• Look at the “30 investors who held their rank” – these are steady, consistent performers. In volatile markets, consistency is a signal.
• Ask potential investors about their recent deals – not their 2015 hits. Termina now weighs recent investments more heavily.

For VCs and Angels

• Track your own 25 attributes – even if you don’t appear on the list, understanding what Termina measures helps you refine your thesis.
• Build your AI portfolio now – this year’s methodology already rewards AI exposure. Over the next 2–3 years, the premium will likely grow.
• Submit your own data – if you think your track record is under-represented in Crunchbase, use the form.

For Revenue Teams Pitching to VC-Backed Companies

• Know your investor’s position on the Seed 100 – top-ranked investors often require portfolio companies to hit aggressive ARR milestones.
• Use AI as a wedge – when selling into seed-stage companies backed by top-ranked investors, emphasize how your product aligns with the AI-first trend those investors are betting on.

The Bottom Line

Termina’s 2026 methodology is both backward-looking (exits) and forward-leaning (recent follow-on rounds, AI footprint). For B2B founders and GTM teams, the key insight is simple: exit potential drives ranking, and AI now drives exit potential.

As the seed market grows more competitive—1,974 investors vying for the top spots—the ability to separate signal from noise becomes critical. Termina’s 25-attribute analysis, with its updated weighting of recent activity and explicit AI tilt, is the most rigorous attempt yet to measure what matters in early-stage venture.

Whether you’re on the list or studying it, the takeaway is the same: data-driven judgment beats gut instinct. And in a market where AI is rewriting the rules, that’s the only edge that lasts.
