Nooks Raises $500M in Growth Capital and Launches Node AI Sales Assistant

Nooks has announced Node, which it calls the first AI personal assistant for sales, alongside a Revenue Agent Platform and $500 million in growth capital from General Catalyst's Customer Value Fund. The number needs unpacking: this is not an equity round. The Customer Value Fund pays up front for sales and marketing at companies with predictable customer economics and is repaid from the customer value that spending creates — Nooks pays when it is paid.

What does the $500M actually buy?

The financing rests on figures Nooks supplies itself: more than 2,000 companies run on the platform, including Glean, Notion, Deel, Factory and Replit. The company reports net revenue retention of 135%, year-over-year growth of roughly 3x, and claims customers typically build 3x more pipeline. More than half of customers use more than one product. None of these figures comes with an independent audit or methodology note, so treat them as vendor-reported until verified. Nooks says its own go-to-market runs on Nooks, which it argues means it knows what every dollar turns into.

General Catalyst partner Pranav Singhvi said AI changed how software gets built and Nooks is changing how it gets sold. Dan Lee is CEO; Nikhil Cheerla is cofounder and CTO. The money funds new products, enterprise and international expansion, and hiring — more than 100 open roles.

How does the Revenue Agent Platform work?

Nooks defines a true revenue agent by three properties. It is goal-oriented, owning an outcome such as moving a deal to its next stage rather than finishing one task and waiting for a prompt. It has durable context, remembering every call, email, stakeholder and objection over months or years. And it is self-learning, improving with each interaction. The company concedes most AI tools in sales have only one or two of these properties, and that the third is the hardest.

The infrastructure claim is central. Nooks says any AI tool can generate an email, but its agents make calls and send email on Nooks' own infrastructure, so they see the reply, the meeting and the closed deal. Nooks Research trains agents on real sales interactions, and each agent rehearses against a simulated buyer before it reaches a real one. Deal, Outbound, Expansion and Coaching Agents run today; Inbound Agents are due in the first quarter of 2027 — a wait measured in years, not quarters, for that piece.

What changes for the rep?

Node inverts the standard relationship: for years people prompted AI; with Node, the AI prompts you. Nooks calls it the "EA for the AE," an executive assistant for the account executive. It works deals in the background and comes to the rep first.

Its deal-management functions are concrete:

• It remembers what was promised on last week's call, drafts the follow-up, and sends it once the rep approves.
• It notices when a buying-committee member goes quiet and flags the risk before the deal stalls.
• When a deal slows, it drafts the move most likely to restart it, based on similar deals.

Every member of a deal team gets a Node, and the Nodes share what is working. Reps approve every send — yet Nooks reports 96% of agent-drafted emails go out without edits. That 96% is the most interesting number in the announcement, and the one most in need of a stated denominator: over what period, across how many customers, measured how? Node is currently waitlist-only, which limits independent verification.

Lee argues AI will push companies to want more salespeople, not fewer, saying Node made Nooks' own sales team productive enough that it is accelerating hiring. Agents take follow-ups and admin, in his framing, while reps handle strategy, creativity and earning a buyer's trust. The claim runs against the common expectation of headcount reduction; Nooks' own hiring is the offered evidence, a single-company sample.

Who is Nooks up against?

The AI sales market is crowded across data, content, execution, deal intelligence and agents. Nooks bundles execution, deal management and coaching in one platform.

Its most direct rivals are outbound AI SDRs: Artisan's agent Ava finds leads and handles email follow-ups, while 11x.ai runs outbound across email, LinkedIn and voice. Notably, many companies that tried fully autonomous AI SDRs have reportedly moved back to hybrid models with human review — which makes Nooks' rep-approves-every-send design look aimed squarely at that gap, though it also caps how autonomous the product can honestly claim to be.

Elsewhere, 1mind uses a face-and-voice AI agent to greet website visitors and announced $40 million in funding. Letter AI puts an AI coach on live deals and raised a $40 million Series B. Gong pioneered deal intelligence and has passed $300 million in ARR. In execution, Clari and Salesloft have merged to combine forecasting and execution tooling. Against both, Nooks pitches agents that go beyond analysis and take the follow-up action themselves.

The differentiator, if it holds, is closed-loop infrastructure plus self-learning. The test will arrive when Inbound Agents ship in 2027 and when the 96% unedited-send figure faces outside scrutiny.
