Series D

TL;DR

Late-stage funding round, often a final pre-IPO round or a 'bridge to liquidity' for companies that have grown past Series C.

Series D and beyond are typically used to extend runway to IPO, fund acquisitions, or finance growth that the public markets will price more efficiently than later. They're often led by crossover funds, sovereign wealth funds, or strategic investors. Round sizes range from $100M to several hundred million.

Valuations at this stage become increasingly sensitive to public-market comps. A Series D priced ahead of the comp cycle can become a 'down round' if public multiples compress before IPO.

Worked example

At $90M ARR growing 80% YoY, a $150M Series D at $1.4B pre / $1.55B post — pre-IPO crossover round led by a hedge fund and a sovereign wealth fund, with a 1× non-participating preference and IPO-target ratchet.

Common pitfalls

• Pricing Series D off peak comps and then needing to take a down round at IPO.
• Accepting structure (preferences, ratchets) that becomes painful in a tougher market.
• Failing to plan for liquidity events for early employees.
