PORTOLA VALLEY, Calif., April 3, 2024-- G2 Venture Partners, a venture capital firm investing in transformative technology companies at their inflection points to build a sustainable future, today announced that Ellie McDonald and Jeannine Sargent have joined the firm.

Ellie McDonald joins G2 Venture Partners as an Investor, having spent the past seven years working across investment and engineering disciplines. Ellie will work closely with G2’s investment team to identify the next generation of climate decacorns.

She also holds a Master’s in Systems Engineering from the University of Pennsylvania and an M.B.A. from Wharton.

“I’m thrilled to have the chance to invest in companies driving positive change in the climate and sustainability sectors as a member of the experienced team at G2. I’m a strong believer that amid the growing climate tech landscape, significant room remains for impactful, high-yield investments that will continue to transform traditional industries. I am excited to use my investing and engineering experience to identify and support the disruptive teams who are driving efficiency and sustainability,” said Ellie McDonald.

Jeannine Sargent joins G2 as an Operating Partner, bringing more than 30 years of experience innovating and building technology companies in emerging markets across multiple industries, geographies, and business cycles.
