Pros

January is one of the rare companies where you can truly be proud of what you build. Its mission is to improve people’s lives by empowering them to understand their bodies—helping them eat better, manage glucose levels, and take control of their health. Today, the company is going far beyond glucose by incorporating blood tests, wearable devices, and other health inputs. Using advanced machine learning and AI, January delivers personalized insights and actionable recommendations that don’t just extend longevity but meaningfully improve healthspan. The team includes some of the brightest minds, united by a deep commitment to this vision. At the center is the CEO, whose relentless dedication ensures that January’s mission can reach and benefit the population at large.

Cons

A startup like this isn’t for everyone—and that’s what makes it special. Success here takes commitment and a true all-in mindset. While we value work-life balance, thriving at January means going beyond “just doing a job” to helping bring a bold vision to life. If you have a startup mindset and a passion for making an impact, this is the place to excel.

Pros

The new CTO is knowledgeable, reasonable, and passionate about the work that January is doing. Engineers enjoy working for him. And he has led the company in new AI directions, So lots of fun work to do. New leaders in product and business development are also highly competent. Excellent press, partnerships, and user growth. So a good time to be at the company.

Cons

As always, it's a startup. So more hat changes than is typical at a big tech company.
