Every Day Matters

Delivering on our vision is a team effort and together we’re undaunted by the challenge. Using our expertise in synthetic biology, we’re developing a novel pipeline of TIL therapies in oncology, with our first product due to advance into patients in 2022 and a focused pipeline of therapeutics in preclinical development.

Through our collaborations with BMS and Vertex, we’re applying our cytoDRiVE® platform technology to enable discovery of novel therapies with the potential to expand our impact and reach a wider range of patients.

Our Culture

We know that patients are waiting, and we’re fiercely committed to delivering transformative therapies as fast as we responsibly can. We act with integrity and challenge ourselves and each other to bring our best every day.

We’re constantly questioning our assumptions, expanding our knowledge, generating and testing new ideas and approaches. Our curiosity drives our innovation.

We don’t believe in silos or hierarchies. We share ideas, strive and learn together, trust each other, and appreciate the value that every member of our team contributes.

We believe that healthy relationships and high performing teams develop when we can be our whole selves. We make time to connect, have fun, and get to know each other’s stories and interests.

Like the diversity of obsidian sources, our team brings varied backgrounds, identities, and experiences. Our collective knowledge, intellect, and energy is our greatest source of strength.
