Battery elevates 11 team members worldwide to bolster its multi-stage investment strategy across software/AI, infrastructure tech and industrial technology
Battery Ventures, a global, technology-focused investment firm, today announced nearly a dozen new internal promotions across four offices, including the elevation of Justin Rosner—a specialist in industrial technology and life-science tools—to partner.
Battery also named four new principals across its venture-capital and private-equity practices, highlighting the firm’s penchant for promoting talent from within the firm. The new principals are Sudheendra Chilappagari in San Francisco; Michael Hoeksema in New York; Lior Mallul in Tel Aviv; and Lauren Wedell in Boston. Wedell and Mallul both joined Battery in 2018, while Hoeksema joined in 2017. Chilappagari, a former founder and technology product executive, joined the firm in 2021.
“These promotions highlight Battery’s continued, global investment focus, even in the face of macroeconomic uncertainty, and our commitment to backing the most innovative companies across the private-equity and venture-capital markets,” said Jesse Feldman, a Battery general partner. “Justin’s elevation to partner also illustrates the importance of our work in the industrial tech and life-science tools markets, which focuses on backing under-the-radar technologies solving emerging global problems in areas such as food and water safety, medical innovation and next-generation, industrial safety.”
Rosner, based in Boston, joined Battery 11 years ago and worked closely with Battery investments Process Sensing Technologies (PST), which makes industrial instruments and analyzers, and SPT Labtech, a producer of critical lab instruments for the research and life-sciences markets. PST was acquired by DwyerOmega last year; Battery previously sold a stake in the company to AEA Investors. Battery sold a portion of its SPT Labtech stake to EQT Private Equity in 2022.
Rosner remains active with a number of other, current Battery investments in the U.S. and Europe, including AnalytiChem, Axiometrix Solutions, Goodfellow, ifp labs, Mobius Institute, Robotiq, Skalar, .steute Technologies and Titian Software. Rosner graduated from Dartmouth College.
Battery also promoted two team members, Olivia Henkoff and Gavin Tasker, to vice president. Henkoff and Tasker are both software investors; Henkoff is based in New York while Tasker works out of San Francisco. Additionally, four Battery team members were promoted to associate: Bridget Bernardo, Noah Spiesz and Matthew Benda in Boston, and Hailey Wilcox in New York.

An ICC Arbitral Tribunal has awarded AOP Orphan Pharmaceuticals GmbH (“AOP Health”) a total of about EUR 112 Mio in a quantum award issued in the ongoing arbitration proceedings with PharmaEssentia Corp. (“PharmaEssentia”) concerning BESREMi® (ropeginterferon alfa-2b). The award quantifies AOP Health’s damage claims for PharmaEssentia’s intentional breaches at ca. EUR 82 Mio. It also awards AOP Health ca. EUR 31 Mio plus interest as reimbursement for AOP Health overpayments made to PharmaEssentia as a result of excessive pricing in the years 2019-2022. The Tribunal thereby confirmed that PharmaEssentia has been overcharging AOP Health by up to 900% over these years.
