Analysis
Three rounds this month illustrate the same shift: the time between late-stage AI markups is compressing from years to weeks, per TechCrunch's coverage of Higgsfield's round and Pulse's own reporting on the other two:
- Higgsfield -- $400M Series B priced the AI video platform at $5.4B, more than quadrupling its $1.3B Series A from eight months earlier, with annualized revenue jumping from $20M to $700M over the same stretch
- Etched -- doubled its valuation to $21B in under a month without shipping a new product in between; the round itself, not new operating metrics, was the news
- Rillet -- CEO Nicolas Kopp said on X its $100M Series C, valuing the AI-native accounting platform at $1B, "came together in less than 48 hours"
That timeline compression matters because it inverts the traditional diligence process. A round that closes in two days doesn't leave room for the reference calls, cohort-retention analysis and competitive mapping that historically justified a 10-figure valuation. What's replaced it is signal from adjacent rounds -- if ICONIQ, Sequoia and Andreessen Horowitz are all already on the cap table from a prior round, as they were at Rillet, a new lead investor is underwriting the existing syndicate's judgment more than running fresh diligence.
Velaura AI is the clearest example of the pattern reaching earlier stages: the Santa Clara chip designer raised its first priced round -- a Series A -- directly into unicorn territory at over $1 billion, backed by Samsung Catalyst Fund, Mayfield and StepStone Group, skipping the multi-year Series A-to-B-to-unicorn path that used to be the norm. For founders, that's a real opportunity if you can generate genuine multi-investor demand; for LPs, it's a harder set of marks to underwrite, since a valuation set in 48 hours has less institutional memory behind it than one built over three funding cycles.
