Chang Xu brings deep operator-founder experience from co-founding Onion Math, a China-based edtech company that raised around $90M, and serving as the first product manager at Minerva Project, giving her hands-on experience scaling venture-backed startups internationally before becoming a full-time investor. At Basis Set Ventures, she has developed a systematic thesis around infrastructure investing with four specific themes—"raise the ceiling," "lower the floor," "open space," and "data privacy"—and focuses on developer-led products where engineers drive adoption from the bottom up rather than through top-down sales.
