Reach - Who We Are

Reach is a pioneer in a new frontier of technology. Born out of MIT, incubated in YC, and developed in an "office space" that was once the oven of a cookie factory, we are a group of curious, passionate, and creative problem solvers, and we approach our work with vigor and humility.

Much has changed since our cookie factory days, but our core philosophies have remained. Decisions are made quickly, meetings and politics are kept to a minimum, and everyone here does high-visibility work that has considerable influence on our product and company. We have weekly team lunches, quarterly offsite company events, and often spend time together outside of work bicycling, rock climbing, playing music, and hosting happy hours.

We highly value diversity at our company - in not only professional capabilities and experience, but also in personal interests, schools of thought, musical tastes, and walks of life. We prioritize inclusivity, and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States.
