Pros

A lot of really helpful, hard working coworkers! Complex product is interesting to work on

Cons

I exclusively talked about climate motivations when interviewing and also mentioned some reservations I had about the mission. I was repeatedly reassured and ended up joining. Unfortunately, I ultimately chose to leave Mainspring as I struggled to see any true climate mission or positive impact within Mainspring. I found that they went against genuine climate progress both on a large scale in their disappointing technology and on a small day-to-day scale. I also struggled to feel there was a genuine commitment to diversity as management told us to park in handicapped spots and I was denied a small desk accommodation for a medically documented disability. Also very poor benefits and pay, but this could have been overlooked for a genuine mission.

Pros

The people are some of the brightest, most well-rounded human beings I've ever met. The problems being worked on are extremely interesting technically, and they'll have a huge impact on making energy clean and affordable. The product is fascinating to learn about, and there's really no shortage of ways to make it better. Despite being a small startup with lots of potential, Mainspring's culture is not toxic at all: there's no pressure to sacrifice your mental and physical wellbeing in order to crank out more work to one-up coworkers. In fact, the core cultural values are clearly stated and are designed to maximize longevity and general satisfaction at work, while moving the company's goals forward. Employees seem happy and have families/a multitude of hobbies outside work. The leadership is excellent, and super down-to-earth. There is a lot of trust built between the difference layers of the organization. Everything is very transparent, and I can tell we are on a positive trajectory.

Cons

There are no major drawbacks that I can tell. Of course, every startup is going to have a bit more work (on occasion) than the usual 9-5, more architecture churn than established companies as requirements/priorities change, and a bit less "predicability" in roles/responsibilities. However, Mainspring manages it well. It feels like there is just enough support to make things work, and teams are continuing to grow.
