Building Breakout Companies: Plural X Callosum
On Tuesday 28th April, Entrepreneurs First + Plural are teaming up for a conversation with Callosum, one of EF's leading portcos developing systems-level software letting different AI models run collaboratively across diverse chip architectures.
Having done EF in 2024, the team recently raised a $10.25m pre-seed round led by Plural. On the 28th we’ll explore how that idea formed, what it takes to build conviction early, and how breakout companies are built before the market agrees.
Come ready with questions.
