Lisa Burton O'Toole brings an unusual combination of PhD-level engineering expertise from MIT and hands-on founder experience to her role as a venture investor at HearstLab, having previously co-founded a marketing technology startup that HearstLab itself funded before she joined as an investor. She approaches investing in women-led teams as a data-driven market opportunity rather than purely a social mission, while actively architecting HearstLab's mentor network of 100+ women leaders at Hearst who provide hands-on support to portfolio companies.
