Why Law Firms Mostly Can't Use Pulley or Carta at All

If your firm is a traditional partnership or professional corporation owned entirely by licensed attorneys, you generally don't have the problem these tools solve: there's typically no outside investor cap table to manage, no 409A valuation to run, and no stock option pool to model, because the firm usually isn't structured to issue any of those things. Partnership equity in most firms moves through partner buy-ins and profit-sharing formulas, governed by the partnership agreement itself, not software.

Don't force a mismatch here. A well-drafted partnership agreement, maintained by your firm's own counsel, does the job that a cap table tool does for a venture-backed startup.

The exception shows up when a law firm builds a separate legal technology product or a client-facing tool alongside its practice, spins it out as its own C-corp, and wants to raise outside capital or grant equity to non-lawyer engineers building it. That entity is a startup like any other, and Pulley or Carta work exactly as designed for it.

Keep that entity's cap table entirely separate from the firm's own partnership structure, both for regulatory clarity and because mixing the two invites exactly the kind of scrutiny that triggers a bar inquiry.

Most firms bring in new partners through a buy-in, where an associate purchases a capital stake over a period of years, combined with a profit-sharing formula tied to origination credit, billable hours, or a hybrid of both. None of this needs a cap table tool; it needs a clear, well-drafted partnership agreement and a managing partner or committee that actually enforces it consistently.

Where firms run into trouble isn't the mechanics, it's inconsistency: one partner's buy-in terms differing meaningfully from another's without a documented reason invites exactly the kind of internal dispute that dissolves partnerships.

In the small number of states currently allowing non-lawyer ownership under an alternative business structure framework, a firm choosing to bring in outside capital would face a genuinely different situation, closer to a traditional startup cap table, though still layered with legal-ethics compliance requirements specific to that framework. This is a significant, firm-defining decision that needs your state bar's guidance and specialized counsel, not a product comparison article.

If you're in this position, the cap table tool is the least complicated part of the decision.

• Confirm your state's current rule on law firm ownership with your state bar, since rules in this area are shifting in a handful of jurisdictions.
• If you're spinning out a separate legal tech product, keep its cap table and entity structure fully separate from the firm.
• Have your firm's partnership agreement reviewed by outside counsel if buy-in terms haven't been updated in several years.
• Don't sign up for either platform before confirming there's an actual structure it would track.

For most firms, the honest conclusion is that the right next step is a conversation with your firm's own counsel about the partnership agreement, not a decision between these two products.

Since most associates and non-partner attorneys aren't eligible for equity at all under a traditional structure, the retention lever firms actually have is a clear, well-documented path to partnership: transparent origination and billable-hour criteria, a realistic timeline, and consistent application of both across associates rather than case-by-case favoritism. Write this down in the same way you'd document a vesting schedule, since ambiguity about the path to partnership is one of the more common reasons strong associates leave for a competing firm.

A documented path costs nothing to maintain and does more for retention at most firms than any equity structure would, given how few firms can actually offer equity to non-partners in the first place.
