Top Investors Behind the AI-Native Wave

CognitionHub's Follow the Money research tracked $4.0 billion raised across 72 AI-native companies in 16 sectors between September 2025 and March 2026. A handful of venture firms appear repeatedly across that data — not in adjacent sectors, but in unrelated ones, simultaneously, within the same six-month window.

The top investors identified across the Follow the Money data:

• Andreessen Horowitz
• Y Combinator
• Sequoia Capital
• Coatue Management
• Index Ventures
• Greylock
• General Catalyst

The most active firms

Andreessen Horowitz appears across seven distinct sectors in the Follow the Money data: legal, accounting and tax, insurance, healthcare, education, real estate, and financial services. No other firm in the report matches that breadth.

Y Combinator is the most numerically active participant, appearing as a seed investor across insurance, customer support, field services, supply chain, and HR. YC operates at pre-revenue stages, which makes it a leading indicator. When a thesis clears YC's bar, it represents early validation before institutional capital has made its call.

Sequoia Capital, Coatue Management, Index Ventures, Greylock, and General Catalyst each have positions in four or more companies across unrelated sectors in the same six-month window. The cohort overlaps on the largest deals: Sequoia co-led Harvey's $200M Series G at an $11B valuation; Coatue led Decagon's $250M Series D at $4.5B; Index led 7AI's $130M Series A in cybersecurity; Greylock backed Nir Zuk's return at Cylake with a $45M seed.

What the cross-sector pattern describes

When the same firm funds legal AI, insurance AI, and healthcare AI within the same six-month window, the thesis is not sector-specific. The bet is on a category-level shift: AI-native architecture replacing the cognitive and decision-making functions currently performed by human professionals across every sector simultaneously.

Three observations follow from this pattern:

Investor pedigree is a validation proxy at early stage. For AI-native companies without significant revenue history, the identity of the lead investor carries information that product metrics cannot yet provide.

Outcome-based pricing is the commercial model this capital is backing. The firms most active across sectors have consistently backed companies that charge for results rather than seats. The pricing model is not incidental to what attracted the capital.

Decision-making within these firms is concentrated. Index, Coatue, Sequoia, and a16z each route investment decisions through a small number of senior partners with sector or thesis mandates. When those partners move across sectors simultaneously, the signal is concentrated conviction, not distributed portfolio construction.

The seed inflation signal

Across the Follow the Money data, seed rounds at $45M, $80M, and $230M closed within the six-month window. Rounds of this size at seed stage were not standard practice five years ago. The window between founding and institutional Series A is compressing. By the time a company reaches Series B, the cap table is typically set.

The cross-border dimension

Three of the five largest rounds in the Follow the Money report came from non-US companies, in Sweden, the UAE, and Israel. The lead investors on those rounds are primarily US-headquartered. They are writing cross-border checks at scale, following founding teams and theses regardless of incorporation geography.

"This is not a purely American phenomenon. Significant AI-native rounds came from Sweden, Switzerland, UK, Germany, France, Finland, Israel, and the UAE."
