Atlas Venture
Boston-based firm focused exclusively on early-stage biotech and therapeutics company creation.
Atlas is old-school VC done right in biotech — they actually understand the science and have the patience for long development cycles. Bruce Booth is genuinely one of the smartest biotech investors out there, but he's also quite opinionated and will push his views hard. They're great for founders who want strategic guidance and industry connections, less great if you want to be left alone to execute. Their digital health practice is newer and still finding its footing compared to their biotech chops. They move deliberately (sometimes too slowly for Silicon Valley standards) but when they commit, they really commit with follow-on capital and extensive support.
- —Best for: Biotech founders who want strategic, science-savvy investors
- —Watch out for: Slow decision-making and very hands-on management style
- —Known for: Deep life sciences expertise and strong follow-on support
