Partner at Pelion Venture Partners
View Live Interactive Profile →Blake Modersitzki is listed as a Partner on Pelion's official team page. He was identified as a Managing Director of Pelion in the firm's May 2013 fifth-fund announcement and is named as a Manager of the General Partner in the Form D filings for Pelion Ventures VIII, L.P. and Pelion Ventures VIII-C, L.P. He served on the board of Weave Communications, Inc. (NYSE: WEAV); the company's proxy statement filed 28 April 2026 records that he was not standing for re-election at the 2026 annual meeting, and that the Pelion funds' Weave shares are attributed to him in the beneficial ownership footnote. Cy4Data Labs' April 2025 funding announcement quotes him as Managing Partner at Pelion, a title that differs from the plain "Partner" shown on Pelion's own team page. No education or prior employment for him could be sourced from Pelion or from another acceptable source.
