Valor Atomic sues Day One over pro rata rights

Valor Atomic, a nuclear startup, is seeking a declaratory judgment against its pre-seed investor, Day One Ventures, regarding pro rata rights in its $1 billion Series B round led by Sequoia at a $6 billion valuation. Day One, which invested $1 million in seed and $15 million in Series A, holds approximately 5% of the company. The dispute centers on Sequoia's requirement that all major investors waive their pro rata rights to allow the lead investor to reach its ownership target. Day One asserted springback rights, arguing it was unfair for other investors to waive rights while a strategic investor was allowed to participate.

The CEO of Valor Atomic reportedly expressed frustration with Day One's stance. The case highlights a broader debate in venture capital about whether pro rata rights are outdated, with some seed investors arguing they are essential for protecting ownership, while larger funds often waive them to secure larger positions in late-stage rounds. Jason Lemkin argued that Day One was wrong to sue, as the founders are not obligated to accommodate individual investor grievances, and that picking a fight with a founder is a pragmatic mistake.
