Winning a pro-rata right is easy. Using it in time is hard. How a pro-rata capture vehicle wires follow-on capital in 72 hours and protects ownership.
Disclosure: PRCV is a mechanism AOS uses across the ventures it builds, including its own. The economics below are AOS's own model; treat the numbers as design parameters, not a track record.
Plenty of funds win the right to follow on. Far fewer can actually move when the round does.
Here's a quiet way to lose ownership in a company you helped build. You negotiate a pro-rata right at seed. The company does well. A Series A comes together quickly. You scramble to assemble a special-purpose vehicle, line up the capital, paper the docs, and by the time you're ready, the round has closed, your allocation got trimmed, and your stake quietly diluted. You had the right. You couldn't use it in time.
PRCV, the Pro-Rata Capture Vehicle, exists to close that gap. The point isn't to grab a bigger share than you negotiated; it's to actually capture the share you already won, before timing erodes it. It's the plumbing that turns a negotiated right into realized ownership, fast, and on terms that favor the people whose capital is at work.
A PRCV is a standing, pre-committed pool of capital that does one thing: exercise pro-rata and super-pro-rata rights in studio-originated companies. The capital is already raised. The documents are already drafted. The mandate is already approved.
A word on the super-pro-rata part, since it cuts both ways. Aggressive super-pro-rata rights can make a company harder to finance later: they crowd the cap table and can deter new or strategic investors who want room to take a meaningful position. So the right is used selectively and sized with restraint, never as a default to maximize ownership at the next round's expense.
What it is not is a scramble. It's not an ad-hoc syndicate spun up per deal, and it's not a deal-by-deal SPV chasing a closing date. Those have their place, for overflow, but they're the thing PRCV is designed to replace at the front of the line.
The difference is timing. A right you can exercise in 72 hours is worth far more than the same right exercised in six weeks, because the round doesn't wait for you.
When a studio company raises a follow-on round, the allocation runs in a fixed order. Order matters more than most people expect, so here it is plainly:
Founders feel this as one decision, not four. They negotiate with one cap-table voice, share one data room, and deal with one investment committee, not a committee of AncoraOak entities arguing among themselves. That single voice is less a courtesy than a reason founders pick up the phone.
This is where the design favors the LP, so here are the specifics.
The Core Fund runs standard terms: a 2% management fee and 20% carry. The PRCV runs deliberately lighter, 1% on invested capital and 10% carry, and, critically, there is no double-carry. If the Core Fund already takes full carry on a position, the PRCV and any overflow SPV cap at 10%. You don't pay carry twice for following your own winner.
Sizing follows the same logic. PRCV is targeted at 35-40% of the Core Fund, with the fund itself holding reserves of 1.5 to 2.0 times the initial check per position. Distributions auto-recycle for 12 to 24 months, so capital returned from one exercise can fund the next.
Put concrete numbers on it. Say a company raises a Series A and the Core Fund holds 12% with a $3M pro-rata right.
The fund deploys $1.5M from its reserves. The PRCV deploys the other $1.5M within 72 hours. Ownership is preserved, the founder makes one decision, and the LP keeps the upside, at 1-and-10 on the PRCV half, not 2-and-20.
That's the entire reason the vehicle exists. Without it, half that allocation either doesn't happen or gets done at a worse fee load through a rushed SPV. With it, the right becomes ownership at the lowest cost layer available.
None of this works retroactively. The rights have to exist on the original term sheet, which is why every studio-originated term sheet carries the same language at seed: assignable pro-rata (explicitly extending to GP-controlled vehicles), a super-pro-rata option up to 1.5-2.0x where the studio is lead, most-favored information rights across all AncoraOak vehicles via a single data-room covenant, and a clean conflict waiver acknowledging that the studio, the fund, and the PRCV share one investment committee.
Governance keeps it honest. One committee, one memo, one vote, one record. A quarterly pro-rata planning session reads the portfolio like a heat map (traction, round timing, reserve need) so capital is staged before it's needed, not begged for after. Every allocation choice leaves an audit trail, so LPs can see the policy applied the same way every round.
There's a sequence here worth naming. A backer joins through a syndicate, gets monthly dealroom access, graduates to a rolling-fund seat, and eventually becomes a Core Fund or PRCV participant. Syndicates are the on-ramp. Committed capital is the flywheel.
PRCV sits at the center of that flywheel for one reason: it converts a right everyone negotiates and few execute into the thing that actually compounds. Ownership, captured on time, at the lowest fee layer, with the founder dealing with a single voice.
If the dual-entity structure is the chassis, and our colleagues covered that in Dual Entity Model, PRCV is the part of the drivetrain that keeps ownership from slipping every time a winner raises again.
