The Rise of the Reverse Acqui-Hire and What It Means for Your Business

“Our people are our greatest asset” is a long-in-the-tooth corporate cliché. Many startups—particularly those in AI—however, are finding it to be true. With an AI talent war underway, AI heavyweights are seeking new points of leverage. One strategy is the “reverse acqui-hire.” A ‘traditional’ acqui-hire involves an established company acquiring a target outright for access to its employees, who then join the established company. The reverse acqui-hire, by contrast, lets the established company invest in the target for access to both its products and personnel.

Below, I break down the reverse acqui-hire process and a few legal issues for both the established, acquiring company (the “Hirer”) and the target (the “Hiree”):

What to know:

1. Ownership. A typical reverse acqui-hire deal, such as Meta’s investment in ScaleAI involves the Hirer taking a substantial, but not complete, stake in the Hiree (Meta’s stake in ScaleAI is 49%). This is substantial, but isn’t full ownership or control. In theory, such a Hiree could seek additional investment to dilute the Hirer’s stake, seek better licensing terms elsewhere (and terminate the license), or develop additional, non-licensed technology. This is unlikely, however, because of personnel and their incentives.
2. Personnel. The key to the reverse acqui-hire is the Hirer’s access to the Hiree’s talent. With Meta’s $15B investment in ScaleAI, for example, Alexandr Wang, ScaleAI’s CEO, became Meta’s AI chief. Other Hiree employees, including engineers, may similarly be employed by the Hirer. This cross-employment creates a strong disincentive for Hiree personnel—including board members—to take actions adverse to the Hirer.
3. Intellectual Property Ownership. One of the main reverse acqui-hire questions is who owns the intellectual property (IP). As a separate entity (often with majority third-party ownership), the Hiree still owns all of its pre-existing IP rights. The Hiree’s existing IP is typically licensed to the Hirer on favorable terms as part of the investment. Given the sharing of personnel between the Hiree and Hirer, however, there is a substantial question of who owns new IP rights. Good reverse acqui-hire agreements spell out ownership (and any exclusivity) clearly. Failure to do so can create a world of hurt.
4. Confidential Information. Collaboration between the Hirer and Hiree involves substantial sharing of information and know-how, not all of it IP. While confidentiality is covered thoroughly in any agreement, ownership of trade secrets is less easily defined. For example, if the Hiree’s employees develop a methodology for classifying data and this is taught to the Hirer’s employees through cross-employment, does this methodology now also belong to the Hirer? How does the Hirer’s knowledge of this technique affect the valuation of the remaining stake in the Hiree?
5. Regulatory Scrutiny. Much like the special purpose acquisition company (SPAC), which became popular during Covid, the reverse acqui-hire bypasses a substantial regulatory review process. Given that Hirers have often faced antitrust scrutiny in the past, this has obvious advantages. With no full acquisition—only a minority investment—Hirers generally need not seek regulatory approval. There are signs, however, that regulators and politicians are waking up the reverse acqui-hire; additional scrutiny could be applied.

Practice Notes:

1. Ownership & Dilution. Hirers should include anti‑dilution protections or consent rights for new equity issuances so the Hirer’s stake isn’t unexpectedly watered down. Hirers can also seek board observer rights or veto powers alongside these anti‑dilution protections. Hirees should be understand the implications of these provisions before agreeing to them.
2. Address Personnel Conflicts Upfront. If employees hold roles in both the Hiree and the Hirer, the parties should document reporting lines and fiduciary duties to avoid conflicts of interest. The parties should address board composition, observer rights, and compensation that ensure that Hirer and Hiree’s strategic objectives are aligned.
3. Define IP Ownership Clearly. Parties should clearly spell out in the agreement who owns existing IP, who will own newly created IP, and whether any exclusivity applies. Ambiguity here is a recipe for disputes.
4. Strengthen Confidentiality Provisions. Go beyond boilerplate NDAs. Parties should specify how trade secrets, know‑how, and methods shared through cross‑employment will be treated—who owns it, who has access to it, and how it can be used.
5. Anticipate Regulatory Review. Even if regulatory approval isn’t currently required, the parties should plan for contingencies—including exit options or outright acquisition—if the regulatory scrutiny (including by the FTD and DOJ) toward reverse acqi-hires becomes more stringent.

We are still in the early innings of the AI talent war. Much could change as both the technologies and the companies developing them mature. Businesses—Hirees, Hirers, and their competitors—should approach reverse acqui-hires with caution, as there is substantial strategic, IP, and regulatory risk. The AI talent pool is finite and every business wants its share. Reverse acqui‑hires may offer a shortcut, but the risks are real.
