Business Outlook

Pros

Leadership is flexible and supportive. Everybody wants to do a great job, and they do well incentivizing us.

Cons

It is somewhat difficult to move up there. Not necessarily a bad thing, but I do think people should be moved up when they exceed expectations or gain additional certifications, regardless of tenure.

Pros

Working in Client Services at a startup has been both challenging and rewarding. The pace is fast and no two days are the same, which means there’s constant opportunity to learn and stretch outside of a traditional job description. Leadership is visible and approachable, and ideas from the frontline are taken seriously—there’s real room to influence process and product direction. Because the company is growing quickly, there are plenty of chances to step up, take ownership of projects, and build skills that might take years to access in a larger, more rigid organization.

Cons

Honestly, the challenges here are the same as in any startup: things move quickly, priorities can shift, and sometimes processes aren’t fully built yet. For some, that can feel unstructured or overwhelming, but for others, it’s the most exciting part of the role. If you thrive on growth, problem-solving, and being part of building something from the ground up, then it doesn’t feel like a “con” at all.

Fantastic company - all that it appears

Business Outlook

Pros

While the interview process took some time, the company has a really warm and collaborative culture now that I'm inside. Really cutting edge products and the CEO believes in the science but also wants the company to run well. They are investing ahead of what they need with people and space etc. Financially, they are performing ahead of targets which is great.

Cons

Half in office and half remote has its challenges sometimes...
