Pros

- Product makes a ton of sense - Generally smart and kind coworkers - Stock will almost certainly be worth a lot - Basically the forefront of ai pilled work, which is the future

Cons

Pretty broken in terms of amount of work particularly in agent dev. We talk about intensity being a good thing across the company, but we're all barely holding on in agent dev even if people don't say that publicly. I easily work at least 75 hours a week and I know many more working more than me. I've heard of people crying in the office. Like what how is that okay. The work is fun but this kind of working isn't sustainable. If the tech industry weren't cooked attrition would definitely be higher. I think basically every AI company is like this unfortunately and Sierra is probably the most reasonable of all the ai companies in terms of workload.

Pros

I’ve had a fantastic experience so far. The company combines an very impressive, high-profile leadership team with a sophisticated product that’s well ahead of what most startups achieve this early in their journey. The interview process was smooth, streamlined, and thoughtfully designed, making a strong impression from the start. The company culture is highly collaborative and supportive, with a close-knit team that values productivity and rapid innovation. Working here feels like being part of something genuinely elevated. Everyone shares a commitment to pushing boundaries in developing bleeding-edge enterprise AI applications.

Cons

Given the rapid growth and fast-paced environment, it can sometimes feel like there’s a lot to keep up with. Those who thrive here are typically energized by ambitious goals and able to adapt quickly to new challenges.

Pros

Incredible product-market fit, phenomenal leadership, killer momentum. Customers are very, very happy. It feels great to be on a winning team.

Cons

Honestly, no cons to speak of, IMO. It's fast paced, the expectations are very high, and the team is excellent.
