How it happened
Quantum-Si is developing semiconductor-chip-based 'next-generation protein sequencing,' aiming to do for proteins what cheap DNA sequencing did for genomics, and went public in June 2021 via a SPAC merger with HighCape Capital at a $1.46B valuation, backed by an oversubscribed $425M PIPE. Commercial traction came slowly and the market soured on pre-revenue biotech-tools SPACs; the stock fell about 88% to around $180M. Glassdoor reviews across the slide describe the strain internally: employees counted repeated layoff rounds β unusually frequent for a company its size β and pointed to shifting priorities and abandoned projects, with a number describing leadership as insular and slow to set a clear direction.
Employee accounts paraphrase anonymous, unverified reviews posted publicly on Glassdoor β. See our methodology.
