Mainspring Energy Reviews

Pros

facilities, some of the greatest and most knowledgeable people

Cons

The manager of the team was too involved in how employees interacted and was generally was incompetent

Some of the most intelligent yet humble coworkers, great work culture, latte machine, and incredibly transparent CEO.

Cons

In the most expensive area of CA.

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.

Pros

The engineers at Mainspring are not only some of the smartest I've met, but they are also very thoughtful, which makes work enjoyable. The technical work is very interesting (both what I do and what I see others do) and keeps me engaged. Timelines are optimistic as expected for a startup, but it's enforced in a reasonable way such that work/life balance is respected and expected.

Cons

None that I can think of.

Pros

Mainspring is an exciting, quickly growing startup with a truly innovative product. It's full of smart and passionate people who care about solving energy issues through cutting-edge technology. Everyone is generally good to work with, and willing to work hard to support each other. Since it's still a small company, the culture is relatively non-bureaucratic and transparent; everyone has the chance to learn about the high-level company goals, schedules, trajectory, and challenges. I've also had highly positive experiences with management and general company leadership. I've been truly grateful to work at Mainspring, where I'm engaged and challenged in new ways every day. I'd definitely recommend to anyone who cares about alternative energy tech and is willing to work hard to help develop a product with immense potential.

Cons

There have been no major cons for me working at Mainspring. Certainly everyone is expected to work hard and be a team player, and put in extra hours when necessary. The workload can be challenging, as there's always a lot to do. That said, I've been able to achieve a very reasonable "work-life balance."

Pros

Smart and fun people. Transparent culture and management. Lots of genuine passion for the company's clean energy mission. Exciting and challenging work. Great career opportunities. Safety and employee well-being is taken seriously, and I've been impressed with how the company has handled operations during the pandemic. Growing fast and has great vision.

Cons

Hoping to see more women and minorities in senior roles soon. It's a start-up so of course there is lots of work to do - That being said I think that we could be even more proactive about hiring.
