Three agent companies raised money on November 4, and the sizes couldn’t be further apart. Nooks took $500 million for AI that works alongside salespeople. Phaze raised an $8.75 million seed to give agents their own computers. Shackleton AI raised $5 million to put agents on construction sites. What ties them together is the question each one answers differently: where does an agent actually do its work?
Nooks and money that doesn’t cost equity
The Nooks round isn’t a normal venture round. The $500 million comes from General Catalyst’s Customer Value Fund, which gives growth capital to companies whose unit economics are predictable enough to lend against, and it doesn’t take ownership. Nooks says it qualified on 3x year-over-year growth and 135% net revenue retention. Those are its own numbers, but the fund only writes checks like this when the payback math works.
The product launched with it is Node, which Nooks calls an AI personal assistant for sales. Each seller sets a goal, such as hitting quota or breaking into an account, and Node decides which deals and steps move it forward. It then does the work or brings it to the rep for approval. Every person on a deal gets their own Node, and the Nodes share what works, so a manager’s Node can be asked to help multi-thread an account. General availability is planned for early 2027.
Underneath sits what Nooks now calls its Revenue Agent Platform: deal, outbound, expansion and coaching agents, with inbound agents due in the first quarter. It runs on Nooks’ own dialing and email infrastructure, which is the moat. More than 2,000 companies use it, including Glean, Notion, Deel and Replit. Nooks says 96% of emails its agents write are sent without edits.
Phaze gives agents a desktop
Phaze comes from the founders of Parsec, the remote desktop company Unity bought in 2021. The seed round was led by a16z, with Indie, NextView, Makers Fund and Lerer Hippeau. The core product is high-performance remote access for workstations, built for CAD, 3D and design work, with machine pooling so a company can hand out powerful computers as demand changes.
The agent part runs through a local MCP server, still labeled experimental, that lets an agent operate a remote machine by its desktop or command line. Agents inherit the access of the user they work for. One example: an IT support bot connects to an employee’s laptop, tries a fix, and pulls in a human who can enter credentials and hand control back. Phaze supplies the access and leaves the reasoning to the agent.
Shackleton AI works the paperwork between plans and payments
Shackleton AI came out of stealth in New York with $5 million led by Battery Ventures, plus Brick and Mortar Ventures, Trust Ventures and others. The founders previously built Ernest, a tech-heavy general contractor that reached $35 million in revenue in the Southeast. They know where the hours go.
Shackleton’s agents draft requests for information, chase overdue submittals, flag budget variances before pay applications reach approval and turn field notes into daily reports. They work across linked project records, bids, budgets, change orders and field reports, instead of inside one app. The platform launched in June and says it already manages more than $1 billion of project value in over 15 states, for midsize general contractors and chains such as Red Lobster and Dog Haus. It connects to QuickBooks, Sage and the usual office suites. People approve what goes out.
Where the money is going
The gap between $500 million and $5 million says less about the ideas than about proof. Nooks has years of revenue data. Phaze and Shackleton have a working product and a thesis. All three keep a human approving the final action, which is where every enterprise agent product stands in late 2026.
The number to watch is Node’s general release in early 2027. If reps hand it whole deals and the 135% retention holds, sales will be the first white-collar job where agents carry real quota.
