These 21 AI startups raised undisclosed rounds between August 2021 and September 2022, with disclosed amounts ranging from $30K (RedFox AI, Madison, Wisconsin) to $60M (Quartet Health, New York). ContextLabs in Cambridge, Massachusetts closed at $28M in February 2022, and Bobble AI in Haryana, India raised $26M in September 2022. Three companies — bitsCrunch in Munich, Nabu in London, and Panintelligence in Leeds — kept amounts fully undisclosed even within this round type.
Geography across the set is notably fragmented: the US leads with seven entries spread across six cities, while Switzerland places two companies (both in Lausanne), and the UK contributes two more. Healthcare-adjacent AI is a recurring vertical — Quartet Health, Sift Healthcare, Hedia, and Alex Therapeutics all appear in this cohort — alongside B2B analytics platforms and natural language tools. Cambridge, Massachusetts alone hosts two entries: ContextLabs and Infinite Analytics.
