Vertex Ventures US is an early-stage venture capital firm dedicated to empowering technical founders building B2B infrastructure and SaaS companies. Founded in 2015, the firm’s mission is to help founders turn innovative products into enduring, high-impact businesses by providing not just capital, but hands-on operational support and strategic guidance. Their investment philosophy centers on deep partnership—leveraging the partners’ own experience as company builders to help startups refine go-to-market strategies, build exceptional teams, and scale efficiently.

Through its close collaboration and global network, Vertex Ventures US has become a trusted partner in the startup ecosystem, helping founders navigate the challenges of early growth and long-term success.
Vertex Ventures US was founded in 2015 by a group of former company builders and operators, including In Sik Rhee, Jonathan Heiliger, Sandeep Bhadra, and Noah Carr. The partners’ shared experience in building and scaling technology companies gave them a unique perspective on the challenges faced by early-stage founders. They created Vertex Ventures US to “pay it forward,” offering the kind of high-conviction, highly present support they wished they’d had when starting their own ventures. Over the years, the firm has evolved its focus to prioritize technical founders and infrastructure/SaaS startups, while expanding its global reach through the Vertex Global Network, which includes affiliates in Israel, China, India, and Southeast Asia. This evolution has allowed Vertex Ventures US to offer founders access to a broader set of resources, talent, and strategic partnerships.
Vertex Ventures US is riding the wave of digital transformation, as enterprises increasingly rely on cloud infrastructure, SaaS solutions, and AI-driven tools to drive efficiency and innovation. The timing is critical—demand for robust, scalable infrastructure and specialized SaaS platforms continues to grow, fueled by remote work, digitalization, and the rise of open-source software. Market forces such as the need for cybersecurity, data management, and vertical-specific solutions are working in Vertex’s favor, positioning the firm at the forefront of these trends. By supporting technical founders and infrastructure innovators, Vertex Ventures US is helping shape the future of enterprise technology and enabling the next generation of industry-defining companies.
Looking ahead, Vertex Ventures US is well-positioned to continue its impact as the demand for B2B infrastructure and SaaS solutions accelerates. The firm’s operator-first approach and global network will remain key differentiators, especially as startups face increasing competition and complexity in scaling. Trends such as AI, open-source, and vertical SaaS will likely shape the next wave of investments, and Vertex’s deep expertise in these areas will enable it to identify and support the most promising founders. As the tech landscape evolves, Vertex Ventures US will likely expand its influence, helping to build the foundational technologies that power the digital economy. Just as the partners once sought the kind of support they now provide, Vertex Ventures US will continue to be a trusted partner for founders building the future.
