About Rethink Capital Partners
Sources give two founding dates. Investorlist ties the firm, formerly Seavest Investment Group, to 1981 and names Richard D. Segal, Chairman and CEO, as a co-founder. Its venture platform, Rethink Education, launched in 2012. Michael Walden is listed as President and Chief Operating and Compliance Officer, Amy Nelson as Managing Partner of Rethink Education, and Jonathan Winer as Senior Managing Director. Rethink Education IV has raised $48.9M at initial close toward a $150M target, according to ConnectLab. ConnectLab also reports that Rethink Education Fund III closed on $120.5M in 2021. Rethink Impact III closed in February 2025, but its size is not public. SEC Form ADV data cited by Premier Alternatives shows $212.1M in regulatory assets across 27 private funds, 12 venture and 15 real estate.
The firm describes itself as a purpose-driven manager of real estate and venture capital, with impact as its core. Its venture work runs largely through Rethink Education, which invests in early-stage education technology. Several companies in that portfolio are described as AI-enabled. Teal, an AI-powered career platform, raised a $7.5M Series A that Rethink joined alongside CityLight Capital and Flybridge. RYDES, a manufacturing AI company, received a $3.8M Seed round with Rethink as an investor. Edexia, Scout EDU and Edapt Schools appear in Rethink Education's 2025 activity as AI-powered tools for schools and educators. No partner is publicly named as the lead for AI deals.
Rethink Education typically enters at Seed and Series A, occasionally at Pre-Seed or Series B. F4 reports checks of about $500K to $3M, with typical early-stage checks of $1M to $2M. ConnectLab lists the firm's checks at $2M to $10M across Pre-seed, Seed and Series A. Tracxn counts 26 Seed investments and 30 Series A investments, with average round sizes of $2.61M and $11.8M.
