An Israeli entrepreneur with a background in the IDF's special forces and a summa cum laude degree in law and business from IDC Herzliya, he founded Vim in 2015 with Sequoia Israel as founding investor and has since raised over $100 million from investors including Optum Ventures, Anthem, Walgreens Boots Alliance, and Frist Cressey Ventures.

Grant Walter
Grant Walter is the Chairman, CEO and President of KoreLock, a Denver-based IoT technology company that sells turnkey embedded smart lock platforms to the lock and access-control industry.

Its patent-protected, gateway-free Wi-Fi direct technology sits inside tens of thousands of locking devices across 65+ countries. In 2023 Walter was named a Security Industry Innovator for that WiFi-ready platform.

A structural engineer turned quant turned operator, he spent three decades managing risk at Merrill Lynch, Goldman Sachs, and the $14 billion hedge fund allocator Arden Asset Management before founding Everysk in 2013. He holds a PhD in Computer Aided Engineering from MIT and argues that cloud computing, open APIs, and agentic AI are quietly dismantling the spreadsheets and data silos that have governed investment management for decades.
Mazy Dar
Mazy Dar is the CEO and co-founder of Here (formerly OpenFin), a New York workspace-software company that grew out of Wall Street trading floors into an enterprise browser used to fight the 'toggle tax' - the four hours a week knowledge workers lose flipping between apps. A Cornell computer-science and French-literature grad who started as a UBS programmer, Dar built and sold the electronic credit-derivatives business at Creditex (a $625M sale to ICE) before founding OpenFin in 2010 to modernize how applications reach enterprise desktops. In 2024 he rebranded the company to Here, launched an enterprise browser built on Chromium, and raised a $35M Series D to take the technology beyond finance.
Priyanka Agarwal
Priyanka Agarwal is a physician-turned-founder building HealthEx, an AI-powered patient consent and data-rights platform she started in 2022. A practicing UCSF telehealth physician with an MD from Harvard Medical School and an MBA from Harvard Business School, she is rebuilding how patients grant, revoke, and direct access to their own medical records. HealthEx raised $14M led by General Catalyst, connected to national networks through TEFCA, and partnered with MD Anderson, Epic, CLEAR, and athenahealth to make patient-controlled data the default rather than the exception.

A 20-year veteran of healthcare technology, Waller co-founded VisiQuate - a healthcare revenue cycle analytics company - before joining WellStack to lead its expansion into enterprise healthcare data infrastructure. He is known for his client-centered philosophy and belief that growth strategy is a team sport.
