Let me tell you a story I have seen play out a dozen times. A venture fund manager launches Fund I with $30 million. It performs well. She raises Fund II at $60 million. Also performs well. Now she is raising Fund III, targeting $80 million, and the LP interest is strong. When Fund III closes, her total assets under management will cross $150 million. And that is when everything breaks.
At $150 million in AUM, a fund manager transitions from exempt reporting adviser status to full registration as an investment adviser under the Investment Advisers Act. The ERA regime is light. The annual IARD filing fee is $150. The compliance obligations are manageable. The RIA regime is not. Full registration triggers a cascade of requirements: PCAOB-registered audits for every fund, a qualified custodian arrangement, appointment of a chief compliance officer, enhanced marketing restrictions, and the near certainty of an SEC examination within 12 to 18 months of registration.
For a large, established firm, these are table stakes. For an emerging manager who just proved herself with two small funds and a third on the way, they are a trap.
The Retroactivity Problem
The core issue is not that RIA requirements are unreasonable in the abstract. It is that they apply retroactively to funds that were raised and operated under a different regulatory framework. When our hypothetical manager crosses the $150 million threshold with Fund III, she does not merely owe compliance for Fund III going forward. She owes PCAOB-registered audits for Fund I and Fund II — funds that are fully invested in illiquid startup equity, funds that were raised and structured under the ERA exemption, funds whose LPs knew they were investing with an exempt reporting adviser.
The audit fees compound quickly. A PCAOB audit for a single venture fund can run $30,000 to $75,000 or more, depending on the fund's structure and portfolio. Multiply that by two legacy funds plus the new fund, and the manager is suddenly facing $100,000 to $200,000 in unexpected annual compliance costs — costs that must be borne by the funds themselves or absorbed by a management company that was sized for ERA-level overhead.
For a venture fund, this creates a particularly cruel cash flow problem. The assets in Fund I and Fund II are illiquid. They are equity stakes in startups that may not generate a liquidity event for years. The audit fees are due now. The management fee on a $30 million fund generates roughly $600,000 per year at a standard two percent rate, and a significant portion of that is already allocated to operations, legal, and administration. Adding $50,000 to $75,000 in audit costs per fund puts real pressure on an already thin margin. In the worst case, it creates incentives to push for premature exits from portfolio companies — selling startup equity at disadvantageous prices to cover compliance costs. The regulation designed to protect LPs ends up hurting them.
A Familiar Pattern in Regulatory Design
This is a common failure mode in securities regulation: a bright-line threshold that creates a cliff effect rather than a gradual transition. Below $150 million, you are essentially unregulated. Above it, you owe full compliance, including retroactive obligations. There is no ramp, no transition period, no proportionality.
Congress has noticed. HR 3673, the Small Business Investor Capital Access Act introduced in June 2025, would raise the ERA threshold from $150 million to $175 million and index it to CPI, which addresses the nominal erosion problem but does nothing about the structural cliff. Meanwhile, the Fifth Circuit's June 2024 decision vacating the SEC's private fund adviser rules removed another layer of prospective regulation but left the basic ERA-to-RIA transition mechanics untouched.
The SEC's examination program compounds the pressure. New RIAs face an initial examination within 12 to 18 months of registration, which is entirely appropriate for investor protection but creates additional operational burden during the period when the manager is least equipped to handle it. The manager is simultaneously onboarding new compliance systems, conducting retroactive audits, integrating a CCO function, and preparing for an SEC exam. Something gives, and it is usually the quality of attention to the manager's actual job — making good investments.
The Fix Is Simple
The solution is a grandfathering mechanism for pre-existing funds when an adviser transitions from ERA to RIA status. Under this approach, when a manager crosses the $150 million threshold, all funds raised after the transition date would be subject to full RIA compliance requirements — PCAOB audits, qualified custodian, the whole framework. But funds raised and operated under the ERA exemption prior to the transition would be exempt from retroactive audit requirements for their remaining term.
This is not a loophole. It is a principle of regulatory fairness that is well established in other contexts. When Congress enacts new tax rules, it routinely grandfathers existing arrangements. When the SEC adopts new disclosure requirements, it provides transition periods. The idea that regulatory obligations should apply prospectively, not retroactively, is foundational to administrative law. The ERA-to-RIA transition is an anomaly in that it disregards this principle entirely.
The investor protection argument for retroactive audits is weak. LPs in Fund I and Fund II made their investment decisions knowing the manager was operating under the ERA exemption. They received the fund's financial statements. They accepted the risk profile of an emerging manager with a lighter compliance framework. Imposing PCAOB audits on those funds after the fact does not give the LPs information they bargained for — it gives them information they didn't ask for, paid for out of the fund's already limited resources.
A grandfathering mechanism would preserve the investor protection rationale of RIA registration for all new funds while eliminating the perverse incentive structure that punishes managers for growing. It would require no legislation — the SEC has ample authority to implement this through rulemaking or interpretive guidance. And it would send a signal that the regulatory framework supports the growth of emerging managers rather than penalizing it.
Why This Matters for the Ecosystem
The venture ecosystem depends on new manager formation. First-time and emerging managers generate outsized returns in part because they are hungry, focused, and investing at a scale where individual conviction matters. The funds that discover the next generation of important companies are often Fund I and Fund II vehicles run by managers who left larger firms or came from operating roles. Anything that makes it harder for those managers to grow — anything that creates a tax on success at the precise moment a manager is proving herself — is bad for the venture ecosystem and bad for the founders who depend on it for capital.
The audit trap is one of those structural disincentives. It is not dramatic enough to generate headlines. It does not affect large, established firms. But it affects the exact category of manager whose growth we should be encouraging, and the fix is straightforward enough that the only excuse for inaction is inattention. A grandfathering mechanism for pre-existing funds. Full compliance for new funds. Prospective application of regulatory obligations. This is not radical. It is how regulation is supposed to work.
