Equity Tools for AI Agencies: Pulley vs Carta Compared

Many AI automation agencies run a hybrid model: client implementation fees pay the bills while a smaller team builds a reusable product on the side, sometimes with outside capital behind just the product piece. That structure can mean two different equity pools, one for the services company and one for a product subsidiary, which gets confusing fast if you're tracking it by hand.

Pulley's scenario modeling handles a spin-out or a separate cap table for a product entity cleanly, which matters if you're not sure yet whether the product arm stays inside the agency or splits off with its own investors.

Keeping a strong AI engineer once they realize a foundation model company will pay more in cash plus far larger equity is one of the harder retention problems in the industry right now. You won't out-cash those offers, so the case you make has to be about ownership stake, speed of vesting, and how real the exit path actually looks, not just a share count on an offer letter.

Keeping a healthy burn multiple¹ also keeps this conversation honest with your own board or minority investors, since a company burning cash inefficiently has less room to be generous with equity refreshes later.

AI-adjacent agencies get inbound acquisition interest earlier and more often than most services businesses, sometimes from a larger platform company that wants the team more than the client book. That kind of deal moves fast, and a buyer's counsel will want a clean option ledger, signed grant agreements, and clear vesting status for every engineer within days, not weeks.

Carta's format is one a strategic acquirer's diligence team will likely already know how to read, which can shave real time off a deal that's moving on an unusually tight clock.

Because acquisition interest can arrive earlier than in a typical services business, it's worth deciding your position on single-trigger versus double-trigger acceleration before you're negotiating a deal under pressure. A double-trigger clause, vesting acceleration that only fires if both a change of control and a termination happen, protects a buyer from an outcome where the whole team's equity vests immediately regardless of whether anyone stays on.

Write the clause into your standard grant template now, in whichever tool you use, so every future hire gets the same terms instead of a patchwork negotiated deal by deal.

• Ask how each tool prices a smaller team; agency-sized headcount sometimes lands in a different tier than a typical startup.
• Check whether the tool supports a separate cap table for a product subsidiary if you expect to spin one out.
• Confirm 409A turnaround time against your actual fundraising or acquisition timeline, not a marketing claim.
• Ask your outside counsel which format they've seen more often in recent AI-sector deals; that answer changes quickly in a fast-moving market.

Neither tool is wrong here. The better fit depends on whether you're optimizing for fast early turnaround or for a format bigger acquirers already trust.

A 409A valuation for a hybrid agency has to account for lumpy services revenue alongside whatever the product arm is worth, which is harder to model cleanly than a pure-play SaaS company's recurring revenue. Get the valuation firm comfortable with both revenue streams up front, and refresh it after any quarter where services revenue swings sharply, not just after a financing event.

An outdated 409A can surface as an issue in acquisition diligence, and fixing it after the fact can slow the deal down at exactly the moment speed matters most.
