Pros
Somehow they manage to attract some talented employees (but ThoughtLab works them to the ground and they leave.)
Cons
First of all, the" management" (or lake thereof) consist of individuals who are incompetent, narcissists, or incompetent narcissists. They are only interested in $$$ and are unwilling to innovate or improve the work culture for the betterment of the business and their employees. The pay is below average, the benefits are terrible (expensive health insurance, no dental, minimal 401k, minimal vacation, no sick days) and the culture couldn't be more nonexistent. The CEO is devoid of actually leading, and has perpetuated an environment lacking of any empathy, where employees are mistreated right under his nose and no one feels comfortable to speak up, for fear of retaliation.
If you're a "billable" employee, (meaning you're the one producing all of the work for the company,) you will be micromanaged and overworked without adequate compensation and with no hope for career advancement. Creatives steer clear, this is where creativity goes to die!
Lastly, ThoughtLab doesn't have an actual office. They pay for space in co-working offices to say they have locations in SLC/SF/NYC/ATL but in actuality, most of the company works remotely in SLC, with maybe 2 employees in ATL? That is only the beginning of the lies they will tell you, as the sales "team" (just one person) will say anything to secure a new client.
