Motivated team but constant chaos

Anonymous employee

Recommend

CEO approval

Business Outlook

Pros

Full of very motivated people who truly want the company to succeed. Science can be sometimes exciting, and funding is in a better place than many. Salaries are competitive.

Cons

Chaotic, whole approach changes every couple of years so uncertainty is constant. Much of the core business is dependent on the CEO's whims, and everyone under is fighting eachother for his attention. Heavy workload, plus long term incentives are essentially imaginary. Company values those who can pitch over those who can deliver, and speed over quality.

Interesting science, poor communication for small startup

Anonymous employee

CEO approval

Business Outlook

Pros

- Science is often really cool, lots of smart people - Perks of a big company at a tiny startup (snacks/free food, internal Flagship resources). Better runway than at many companies of similar size due to the Flagship ecosystem. - Good pay and benefits

Cons

- FL company employees are second-class citizens compared to Flagship associates/employees. Communication is gatekept between Flagship leadership and Flagship associates. Dissatisfied with communication and growth opportunities as a mid-career employee - Sometimes apparent lack of drug discovery experience in early FL companies
