What does this ranking show about seed AI investing in 2026?

This ranking highlights two different models of seed-stage AI investing. Some investors combine high activity with frequent lead positions, indicating a willingness to set terms and take concentrated early ownership. Others appear more participation-oriented, building exposure across emerging AI companies without necessarily leading the round.

At the top, Andreessen Horowitz stands out because its 6 AI deals are matched by 6 lead deals. That means every listed AI seed deal for the firm is also counted as a lead deal. Khosla Ventures, General Catalyst, and Kleiner Perkins also show meaningful lead activity, while Y Combinator and BoxGroup demonstrate how accelerator or network-driven models can create broad access even when lead counts are lower.

How is this ranking calculated?

The ranking is based on disclosed seed-stage AI deal activity and uses three core fields: AI Deals, Lead Deals, and Representative Portfolio. AI Deals reflect the number of qualifying seed AI investments attributed to each investor. Lead Deals identify how many of those investments the investor led. Representative Portfolio lists example companies associated with the investor’s activity in the ranking.

The order is final and should be read as an activity ranking, not a performance ranking. It does not measure returns, ownership percentage, follow-on participation, valuation, or company outcomes.

Why does lead-deal count matter?

Lead-deal count helps distinguish investors that primarily participate in rounds from those that often define the round. A lead investor typically plays a larger role in pricing, diligence, allocation, governance expectations, and syndicate formation.

In this ranking, the difference is visible. Andreessen Horowitz has 6 AI deals and 6 lead deals, while BoxGroup has 3 AI deals and 0 lead deals. Both are active, but the nature of their activity is different. One reflects lead-heavy deployment; the other reflects participation across multiple seed AI companies.

Investor Analysis

[Andreessen Horowitz](/investors/andreessen-horowitz)

Andreessen Horowitz ranks first with 6 AI deals and 6 lead deals. Its position is driven by both the highest AI deal count in the ranking, but also by the fact that every listed deal is a lead deal. Representative companies include Replit, Pillar, Pit, Thinking Machines Lab, and Probably. The mix suggests a broad AI seed thesis spanning developer platforms, frontier-model activity, and application-layer companies, with a clear preference for taking lead positions rather than passive exposure.

[Khosla Ventures](/investors/khosla-ventures)

Khosla Ventures ranks second with 5 AI deals and 3 lead deals. Its representative portfolio includes Sakana AI, Synthetic, Pramaana Labs, Clair Health, and Genesis AI. The firm’s ranking reflects both volume and selectivity in leading rounds. The portfolio mix points to a thesis that includes advanced AI research, synthetic data or simulation-oriented approaches, healthcare AI, and applied automation. With 3 lead deals, Khosla Ventures shows a meaningful but not exclusive focus on leading seed-stage AI rounds.

[General Catalyst](/investors/general-catalyst)

General Catalyst ranks third with 4 AI deals and 3 lead deals. Representative companies include AgentMail, Thinking Machines Lab, Autoscience, and Status AI. The firm’s high lead ratio indicates that its seed AI activity is weighted toward conviction-based positions. The presence of companies such as Thinking Machines Lab and Autoscience suggests interest in technically ambitious AI categories, while AgentMail and Status AI point toward workflow and application-layer opportunities.

[Y Combinator](/investors/y-combinator)

Y Combinator ranks fourth with 4 AI deals and 1 lead deal. Its representative portfolio includes AgentMail, Leadbay, Status AI, and Proception. The ranking reflects Y Combinator’s role as a high-access seed-stage platform rather than a traditional lead investor in every round. Its 4 AI deals show continued relevance in early AI company formation, while the single lead deal differentiates it from firms such as General Catalyst, which has the same AI deal count but 3 lead deals.

[Kleiner Perkins](/investors/kleiner-perkins)

Kleiner Perkins ranks fifth with 3 AI deals and 3 lead deals. Its representative portfolio includes Health Universe, Harvey, and Mirendil. Although its AI deal count is lower than the top four investors, its lead-deal count matches its total deal count, indicating a concentrated and lead-oriented seed AI approach. The companies listed point to interest in enterprise, healthcare, and professional workflow AI, with Harvey standing out as a notable example of AI applied to knowledge work.

[Index Ventures](/investors/index-ventures)

Index Ventures ranks sixth with 3 AI deals and 2 lead deals. Representative companies include Uncovr, NewCore, and Build. The firm’s position reflects a balanced approach: active enough to place among the top seed AI investors, but somewhat less lead-heavy than Andreessen Horowitz or Kleiner Perkins. With 2 lead deals out of 3 AI deals, Index Ventures appears to combine direct conviction with selective syndicate participation.

[Seedcamp](/investors/seedcamp)

Seedcamp ranks seventh with 3 AI deals and 2 lead deals. Its representative portfolio includes Omniscient, Uncovr, and Waniwani. Seedcamp’s ranking reflects active early-stage AI participation with a relatively strong lead component. The firm’s profile is consistent with a seed-focused investor building exposure to emerging AI startups while still taking lead positions in selected rounds.

Neo

Neo ranks eighth with 3 AI deals and 1 lead deal. Representative companies include Bluesky, Miravoice, and Altara. Neo’s ranking is driven by deal activity rather than lead frequency. With 3 AI deals, it matches Index Ventures, Seedcamp, and BoxGroup on count, but its 1 lead deal places it below Index Ventures and Seedcamp. The portfolio suggests a strategy of backing early AI-enabled products and teams while selectively leading.

[BoxGroup](/investors/boxgroup)

BoxGroup ranks ninth with 3 AI deals and 0 lead deals. Representative companies include Era, Altara, and Proception. Its placement shows meaningful seed AI participation, but the absence of lead deals distinguishes it from the other investors with 3 AI deals. BoxGroup’s role in this ranking is best understood as access-driven participation across early AI companies rather than lead-led round formation.

[a16z Speedrun](/investors/a16z-speedrun)

a16z Speedrun ranks tenth with 2 AI deals and 2 lead deals. Its representative portfolio includes ZeroDrift and Orbital. Although it has the lowest AI deal count among the ranked investors, both listed deals are lead deals. That makes a16z Speedrun a smaller but highly lead-oriented participant in seed AI investing, especially within early company formation and accelerator-style venture activity.

Which investors show the strongest lead orientation?

Andreessen Horowitz, Kleiner Perkins, and a16z Speedrun show the clearest lead orientation because their lead-deal counts equal their AI deal counts. Andreessen Horowitz has 6 AI deals and 6 lead deals, Kleiner Perkins has 3 AI deals and 3 lead deals, and a16z Speedrun has 2 AI deals and 2 lead deals.

This matters because lead-oriented investors often play a more central role in shaping early financing terms and syndicates. By contrast, investors such as BoxGroup, with 3 AI deals and 0 lead deals, still show meaningful activity but appear in this ranking as participants rather than lead investors.

What should founders take from this ranking?

For AI founders raising seed capital, the ranking suggests that investor fit depends on more than deal count. A firm with many AI deals may offer broad category familiarity, while a firm with many lead deals may be more likely to anchor a round.

Founders seeking a lead seed investor may focus on firms with higher lead-deal counts, such as Andreessen Horowitz, Khosla Ventures, General Catalyst, Kleiner Perkins, Index Ventures, Seedcamp, and a16z Speedrun. Founders seeking syndicate depth, network access, or additional early-stage participation may also find relevance in investors such as Y Combinator, Neo, and BoxGroup.
