Proven
Strategy
We invest in early stage, therapeutic-oriented companies across the life science spectrum, as well as opportunistic late-stage companies. Our over-arching goal is to find breakthrough therapies that have the potential to change the practice of medicine. We are thesis-driven and committed to seeking out novel, disruptive and defensible technologies to meet unmet clinical needs.
Proven
Results
We believe that innovation, not incrementalism, drives significant exits and successful financial returns. By using our strong operational skills, we help our portfolio companies execute their business plans and see their visions become a reality. Additionally, our strong ties with key players in major life science companies facilitates strategic partnerships and acquisitions.
Lightstone Ventures was founded in 2012, when the healthcare teams from Advanced Technology Ventures and Morgenthaler Ventures joined forces, to invest in therapeutic-oriented companies across the life sciences sector.
Company Builders
The Lightstone team collectively has over 50 years of experience in the venture capital industry, and nearly 100 years of operational experience including extensive growth company experiences. The team has been part of start-up ventures from inception through liquidity and plays a critical role in helping to source, evaluate, guide and build successful healthcare companies. Along with Operating Partners and Scientific Advisors who provide specific industry and technology experience, we believe the tight link to both industry and academic community creates a competitive advantage.
A Clear Directive
Using a thesis-driven investment strategy, we focus on understanding key market sectors and seeking out disruptive technologies while building and nurturing relationships with key thought leaders. Additionally, our global footprint with offices in US, Ireland and Singapore allows us to build a network with non-US strategic and financial funding sources, as well as exploring novel development and commercialization strategies in these geographies.
Steady, Proven Track Record
We have created a whole that is greater than the sum of our individual successes. Members of the Lightstone team have been involved in several of the largest venture-backed life science exits over the last decade including: Ardian, Acceleron, ALX Oncology, Calithera BioSciences, Claret Medical, Disarm Therapeutics, MicroVention, Nimbus, Plexxikon, Portola Pharmaceuticals, Promedior, Proteolix, Ra Pharma, Tizona Therapeutics, Twelve and Zeltiq.
