Bucky Moore on Lightspeed: seed ownership compression, ghost ship acquisitions, and neo-lab funding dynamics
Mar 20, 2026 with Bucky Moore
Key Points
- Seed funds are losing ownership faster than they gain it, with typical positions compressed from 10% at seed to mid-teens after Series A, crippling single-name fund returns.
- Frontier AI companies face a capital trap where their Series B requires proof of cutting-edge capability, which demands expensive compute infrastructure that the seed round rarely covers.
- Larger acquirers are doing 'ghost ship' deals that integrate technology and talent while leaving companies operationally separate, replacing traditional M&A structures.
Summary
Bucky Moore, Lightspeed Venture Partners
The structural problem in seed investing right now is ownership compression. Moore describes a pattern where a fund takes roughly 10% at seed, then watches the company price its Series A somewhere between $150M and $300M post-money. To maintain a meaningful position, the fund tries to co-lead that round and ends up in the low-to-mid teens on ownership — not where it started, and not where it needs to be to return a fund on a single name.
The compression is worse at the frontier AI layer. The neo-labs — the new wave of foundation model companies — face a much higher bar for their second raise than the first. The initial round often gets done on narrative and team. The second requires evidence of frontier capability, which means compute, which means capital, which creates a circular dependency. If a neo-lab can't go big on compute, Moore argues, it simply can't stay on the frontier, and without frontier positioning, the second round doesn't happen on favorable terms.
The acquisition dynamic is also shifting. Moore points to what he calls ghost ship acquisitions — deals where a company is technically acquired but operates with little integration, often structured more to retain talent and technology than to build a coherent combined product. These are becoming more common as larger players look to absorb frontier capability without the messiness of full M&A.
Takeaway: Seed ownership is getting squeezed at exactly the moment when frontier AI companies need the most capital to stay competitive. The funds that win will be those that can commit meaningful dollars at the Series A and beyond — not just plant a flag at seed.
