The sales automation startup is funding its go-to-market with money that is not equity, in a structure that is becoming a template for AI companies with predictable unit economics.
Nooks has secured a $500 million commitment from General Catalyst's Customer Value Fund, the firm's vehicle for financing sales and marketing at companies whose customer economics are already predictable.
The announcement came alongside the launch of Nooks' Revenue Agent Platform and Node, an AI assistant for sales representatives.
The structure differs from a conventional round. General Catalyst does not buy a stake. It funds customer acquisition and is repaid from the value those customers generate, with its entitlement capped at a fixed amount. Once that cap is reached, the remaining customer value stays with Nooks.
Chief executive Dan Lee declined to disclose the detailed terms. No valuation was announced.
Why the Money Is Not Equity
Growth equity dilutes founders and employees. Debt requires collateral and repayment schedules that can strain a young company. The Customer Value Fund sits between the two: it treats sales and marketing spending as an asset that produces measurable future revenue.
That only works if the company can show what a dollar of acquisition spending returns. Nooks argues it can, partly because it runs its own sales operation on its own product.
The fund is paid only when the portfolio company is paid, and the company does not pay General Catalyst out of pocket. The trade-off is that the arrangement is complex and depends on assumptions about retention and expansion that must hold for years.
Pranav Singhvi, partner and co-head of the fund, framed the bet around how software gets sold: AI changed how software is built, and Nooks is changing how it gets sold.
The Numbers Behind the Commitment
Nooks says more than 2,000 companies use its products, including Cursor, Notion, Replit, Glean, HubSpot, Deel and Factory.
It reports net revenue retention of 135%, meaning existing customers spend 35% more year over year, and expects annual recurring revenue to nearly triple by the end of 2026. It did not disclose the absolute figure.
Those metrics are company-reported and have not been independently audited, but they are the kind of predictable expansion that the fund requires.
Sales as the Next Function Rewritten by AI
The pitch is that coding, legal work and customer support have already been reshaped by agents, and sales is next, delayed because persuasion involves judgment and context rather than a single correct answer.
Nooks describes its agents as goal-oriented, meaning they own an outcome such as moving a deal to its next stage, rather than completing one task and waiting. They retain context across calls, emails and CRM records, and improve as representatives edit their output.
The company plans to use the capital to launch products, move upmarket, expand internationally and hire, with more than 100 open roles.
The risk is the same one that follows every AI sales tool: proving that the pipeline it creates converts at a rate that justifies the spending, and that the gain survives as models commoditise.
For now, the deal is a bet that a company with strong retention can buy growth more cheaply by sharing its future customer value than by selling another slice of itself.
