Joining a breakout company furthers your career growth.

Joining a climate tech company lets you build stuff that actually matters.

Now you can do both.

Why joining a climate tech breakout company is socially impactful

Each year, the world releases 51 billion tons of greenhouse gasses to the atmosphere, trapping heat and driving up global temperatures. We need to reduce this by half in the next 10 years to avoid catastrophic effects (mass migration from sea level rise, mass famine from crop failures, extreme weather events). 

This is the defining problem of our generation. 

In addition, because climate change threatens to act as a general “stressor” on society, mitigating it might have positive effects on other areas, such as reducing the chance of large scale war.

Reducing our reliance on burning fuels also reduces air pollution, which causes millions of deaths per year. See: "Fossil fuel air pollution responsible for 1 in 5 deaths worldwide" from Harvard School of Public Health, "Air pollution contributes to 11.65% of deaths globally" from Our World In Data, World Health Organization data set

FAQ

Why can’t I just donate to or invest in climate causes? 

In the past several years, numerous companies like Delta Airlines and Microsoft have declared their net-zero goals. Stripe and Shopify have started major investments in decarbonization funds. 163 of Fortune Global 500 companies have set some sort of climate target. Isn’t this great? It’s capitalism doing the hard work of decarbonization that they should have been doing all along, right?

The reality is that most of these companies are offsetting their carbon through carbon credits, which are grossly underpriced, allowing them to underpay for the damage that they inflict on the planet. For them, more growth is usually correlated to more “activity,” which usually requires energy, and generating energy, more likely than not, means releasing more carbon into the atmosphere, exacerbating the climate problem. 

However, now, a new category of REAL climate companies is emerging. All of the companies on our list fall into this category. These climate companies have aligned their incentives around the act of decarbonization. For them, growing the company means LESS, not more, carbon in the atmosphere. For them, success IS decarbonization.

And in many ways, these companies *are* faster growing than traditional software companies. See this thread for more about how Tesla and CATL (battery manufacturer) have been growing relative to their traditional software peers.

We think that’s what makes these companies special. And their aligned incentives also make them more likely to succeed in both business and decarbonization. 

What’s your methodology for this list? 

Besides doing third-hand research, we also talked directly with the engineering leaders of many of the companies on this list to answer the 3 questions above.

The list is not meant to be comprehensive- it will change over time as we learn about more companies, but we believe this is a reasonable overview of companies.

Are you affiliated with breakoutlist.com?

No we are not, although we have personally found the content on Breakout List helpful in thinking about our careers earlier on. We also recommend WealthfrontList.

Who are you?

We are a group of long time software engineers in Silicon Valley who are concerned about climate change and are following the climate tech movement.


The last several years saw a rise of VC funds dedicated to climate change, allocating capital into this space, but we haven’t seen much around directing labor, especially SWE talent, into this space. Various lists of climate companies exist, but don’t focus on SWEs.
