About Tamarisc

We are a team of scientists, engineers, enetrepreneurs, and strategists distributed between Boston and Los Angeles.

We believe that the built environment is the fabric of our human world, that innovation can enable a better human existence, and that technology+capital are agnostic tools that help good ideas achieve scale and sustainable impact. We believe that technology--at its highest and best use--should shape a physical habitat that informs, supports, and elevates our human experience.

We founded Tamarisc in 2013 to help entrepreneurs create a more beautiful, human-centric world.
