I specialize in
“I help founders raise capital and scale their companies”
Background & Highlights
Early-stage founders (pre-seed to Series A) who are raising capital, scaling their company, or looking for strategic guidance from an investor/operator. I’m a serial entrepreneur, exited founder, and active early-stage investor based in Austin. I co-founded Rallyteam, a venture-backed HR tech company that was acquired by Workday in 2018, and since then I’ve focused on advising and investing in high-potential startups. Through Sher Ventures, I’ve invested in 20+ companies since 2023 across AI, consumer, and deeptech, and I also represent a family office deploying capital into early-stage opportunities. As an angel investor, I’ve backed companies like Calm, Grove Collaborative, BillionToOne, Grin, and 50+ others. I’m especially passionate about helping founders navigate fundraising, growth, and key inflection points while building companies that create real impact. If you’re building and thinking about fundraising, scaling, or navigating key decisions, I’d be glad to connect on Hubble.
