Phase 2 Health | About

Phase2 Health


We founded Phase2 on the premise that many promising technology companies fail prematurely due to the complexity and cycle time inherent in healthcare enterprise sales.

Healthcare has some of the most passionate and capable entrepreneurs in the world who are determined to change healthcare for the better. Phase2 was founded to give those entrepreneurs support where it matters most, acquiring customers and generating revenue.



Dan Baker - Managing Partner

Dan Baker has spent 17 years on the front lines of the largest industry transformation in history, the digitization of healthcare. As an Enterprise Sales Executive, he continuously shattered sales records and was top rep out of 100 for seven of eight years while at NextGen Healthcare. As a sales leader, he has built world-class sales organizations from the ground up to achieve dramatic growth while defining new product segments.

Dan most recently served as the Senior Vice President of Sales for Syapse, a venture-backed, provider-driven, Precision Medicine network and solutions provider based out of San Francisco, CA. He has grown the commercial organization from the ground up to deliver 40x bookings growth, assisted in two rounds of fundraising totaling $70m., and has secured Enterprise-wide contracts with some of the worlds leading community and academic health systems such as Catholic Health Initiatives, Dignity Health, University of Miami, Henry Ford Health System, Aurora Healthcare, Providence Health and Services and Seoul National University Hospital.

Mark Kaiser - Partner

A common thread in Mark’s 11 year healthcare sales career is his affinity for being a “builder”. During his 9 years in the medical device industry, Mark conducted three million-dollar-plus territory turnarounds by implementing creative customer development tactics and time-tested sales processes. Throughout that time, he was recognized for his ability to coach others toward success which underpinned his interest in founding Phase2 Health.

The desire to work closer to the ground floor of healthcare innovation brought Mark to MATTER as Head of Business Development. He worked alongside MATTER’s CEO and other leadership to focus MATTER’s strategic direction, refine the product offering, and implement a partnership development process; securing partnerships with Baxter, Johnson and Johnson, and the American Hospital Association.

After MATTER, Mark co-founded Phase2 Health to address something he learned first-hand from many of MATTER’s healthcare startups – that they needed help in customer acquisition but didn’t have the experience to do so efficiently and were uncertain if they were ready for a full-time senior commercial hire.

Mark is an active member in the healthcare entrepreneurship community and applies a hands-on approach to helping Founders/CEOs build their sales capability.
