About
We make reflective, high-altitude, biodegradable clouds that cool the planet. Mimicking natural processes, our "shiny clouds" can prevent catastrophic global warming.
Specifically: we release a natural compound via reusable balloons to create reflective clouds in the stratosphere. They're *really* effective: 1 gram of our clouds offsets the warming that 1 ton of CO₂ emissions creates for a year. After ~2 years, our clouds compost and settle back to Earth.
Because we will deliver our clouds via reusable balloons, we'll be able to offset warming at <1% of the cost of other solutions. Uniquely, we can also scale to offset *all* of global warming.
We can offset warming from all new global annual CO₂ emissions with ~$30 million of our clouds per year, and every $1 billion of our clouds will cool the world by ~0.1°F!
Sounds like sci-fi? It’s not: we’ve already launched our first clouds, and we’ll offset a substantial amount of warming in 2023!
Company Information
Founded in October 2022, Make Sunsets is backed by Boost VC, Pioneer Fund, and other friends.
We have launched 8 balloons and offset 600+ ton-years of warming
Committed to science, biased towards action.
At Make Sunsets, we believe that we have a responsibility to make bold moves to combat climate change. We're not afraid of controversy or challenges, and are passionate about developing innovative solutions to mitigate the worst effects of global warming. The science and math back us up, but we also recognize that there are unknowns and risks associated with stratospheric aerosol injection (SAI). With climate change rapidly transforming our world, it's crucial that we prioritize action over words. We believe the best time to field test and scale SAI is now.

Meet the founders of Make Sunsets:
Luke Iseman and Andrew Song
In 2015, they met in San Francisco, CA through their shared passion for hardware companies and helping entrepreneurs go from 0 to 1, while Luke was Director of Hardware at Y Combinator and Andrew was an Outreach Manager at Indiegogo. Luke and Andrew went on to start separate hardware companies backed by Y Combinator, angel investors, and VCs. Between the two of them they’ve helped sell millions of dollars worth of hardware and software at various venture backed startups. Now they have the privilege to build a company that will help future generations combat the worst effects of climate change.
