Pros

Solid benefits, finally started giving cost of living adjustments — though they still don’t really match actual inflation. Free snacks and lunch are legit. The real gems here are the coworkers — absolute 'superstars.' You learn so much from the team because most people are insanely hardworking and talented. Management in the lab seems to be improving, especially with more transparency lately — something we've been pushing for forever.

Cons

The favoritism is wild. CLS staff (especially certain ones) get special treatment, while CLA's often take the fall for mistakes. It’s frustrating to see some CLS taking long breaks or not pulling their weight, but still getting a free pass. Meanwhile, CLA's mess up once and are shown the door. What’s worse is the attitude from senior leadership. We've literally been told in company-wide meetings to suck it up because we “signed up” for a chaotic work environment. The CEO even said in a podcast that the extar workload burden (aka burnout) people feel is by design — like, why brag about expecting people to do 2-5x the work they would at another company for the same (or less) pay? It’s giving we don't care about work-life balance...which they do NOT! Literally, heard a senior staff member talking about this in the halls, if work-life balance is important to someone then BTO is not for them. At the end of the day, this isn’t a pro-employee company — not that many are — but to openly say they want you to grind yourself into the ground for "big impact" or leave? It’s a choice. What’s even more frustrating is that these high expectations don’t apply to everyone — some people just coast by, doing the bare minimum and agreeing with whatever leadership says. Total waste of resources.

Pros

A truly well-rounded, ambitious, kind, and supportive leadership team. There’s a strong balance of vision, intellectual curiosity, calmness, ethics, and thoughtful decision-making — all grounded in a genuine commitment to culture and values. The technology is incredible, but what really stands out are the people behind it — talented, driven, and hardworking individuals who care deeply about innovating with purpose and always keeping the patient at the center of everything. The culture is transparent, collaborative, and performance-driven, with strong communication and accountability from leadership. It genuinely feels like one cohesive team, 20-mile-marching forward together towards ambitious, shared goals. Expectations are clear, support is always available, and there’s a real sense that everyone wants each other to succeed.

Cons

BillionToOne offers so much — meaningful work, incredible teammates, strong support, great compensation, and endless opportunities to grow. But it’s also a place where you need to be all in. Success here takes focus, commitment, and genuine passion for what you do. I don’t see that as a negative at all — it’s part of what makes BTO such a special place. The bar is incredibly high for everything we do, and there’s an unwavering commitment to doing things not just the right way, but in ways that were once thought impossible. You’re constantly encouraged to challenge your own limits, think creatively, and find innovative ways to solve complex problems. It’s demanding — but it’s also deeply rewarding.
