In a significant move, Henry Ellenbogen's Durable Capital disclosed a new $380.92 million position in communications software company Twilio (TWLO). The stake, comprising 1.85 million shares, was established during the second quarter of 2026, as revealed in a quarterly 13F filing with the SEC. These filings are released with a delay, so the trades occurred between March 31 and June 30, 2026.
This investment marks a notable return to Twilio for Ellenbogen, who previously led a private market investment round in the company before founding Durable Capital. His firm focuses on identifying and holding what it believes are long-term compounders, often investing in both private and public stages of a company's growth. The new stake gives Durable a 3.70% weight in its reported portfolio.
