200 Satellites, 3 Million Images a Day, and a $9 Billion Valuation
Planet is the most prolific Earth imaging company on the planet. Its fleet of over 200 Dove nanosatellites photographs every square kilometer of land on Earth every single day — more than 300 million square kilometers of imagery captured in natural color, near-infrared, and eight spectral bands. No government agency, no defense contractor, no competitor comes close. Planet’s constellation is ten times larger than the next biggest fleet.
The company’s clients span defense, agriculture, finance, and climate science. NATO, the U.S. Department of Defense, and the NGA rely on Planet for real-time intelligence. Bayer uses it to monitor crop health across millions of hectares. Insurance companies use it to assess disaster damage within hours. At the center of all of it stands Will Marshall, a British physicist who decided that the most important thing you could do with space was point the cameras back at Earth.
An Oxford Physicist Who Studied Quantum Mechanics Under Roger Penrose
Marshall grew up in England with a fascination for both physics and the environment. He earned a master’s in physics with space science from the University of Leicester, then moved to Oxford for his doctorate. His PhD supervisor was Sir Roger Penrose, the Nobel Prize-winning mathematician. The research was esoteric — experiments testing the foundations of quantum mechanics alongside physicist Dirk Bouwmeester. Marshall was operating at the frontier of theoretical physics.
But his interests were never purely abstract. He cared about what science could do for the real world, specifically for the planet. That tension between deep theory and practical urgency would define everything he built next.
NASA Ames: The Youngest Scientist in the Room
Marshall crossed the Atlantic for postdoctoral work at George Washington University and Harvard, then landed at NASA Ames Research Center in Mountain View, California. He was one of the youngest scientists on campus. He joined the science team for LCROSS, the mission that first confirmed large quantities of water on the Moon. He researched orbital debris remediation and co-invented a method for using ground-based lasers to prevent debris collisions in orbit.
Then came PhoneSat — the project that changed his trajectory. Marshall and his colleagues realized that a modern smartphone had more processing power, better sensors, and faster connectivity than most satellites orbiting Earth. They proved it by launching three phone-based satellites for $7,000 each. The insight was devastating in its simplicity: the aerospace industry was spending hundreds of millions of dollars on hardware that a consumer device could outperform.
”What if you could search the surface of the Earth the same way you search the internet?” — Will Marshall
2010: Three NASA Scientists Leave for a Garage in San Francisco
In 2010, Marshall, Chris Boshuizen, and Robbie Schingler quit NASA and founded Planet Labs. The name said everything about the ambition. They set up in a garage in San Francisco and began building the first Dove satellite — a CubeSat the size of a loaf of bread, measuring 10 by 10 by 30 centimeters, equipped with cameras capable of 3-meter resolution.
The aerospace establishment dismissed the idea. Serious satellites weighed thousands of kilograms and cost hundreds of millions. Marshall was building something that weighed four kilograms and cost less than a new car. The bet was not on any single satellite being perfect. The bet was on launching hundreds of them, creating redundancy through volume, and replacing failed units the way a software company pushes updates — continuously.
”The goal is to democratize access to information about our planet.” — Will Marshall
From 28 Doves to the Largest Fleet in History
Planet launched its first two prototype Doves in April 2013. By February 2014, it launched Flock-1 — 28 Doves deployed from the International Space Station in a single release. It was the largest satellite constellation ever launched at the time. The images started flowing. Investors paid attention.
The company raised over $380 million in venture capital from backers including Google, BlackRock, and Marc Benioff’s TIME Ventures. Planet acquired BlackBridge and its RapidEye constellation in 2015, then bought Google’s Terra Bella satellite division in 2017. Each acquisition expanded capability. By 2020, Planet could image every point on Earth’s landmass every single day.
In December 2021, Planet went public through a SPAC merger with dMY Technology Group IV at a $2.8 billion valuation. The stock began trading on the New York Stock Exchange under PL.
Profitability, Defense Contracts, and the AI Inflection
The public market years tested Marshall’s patience. Planet’s stock drifted as investors questioned when daily satellite imagery would translate into consistent profitability. Marshall kept building. Revenue grew to $244 million in fiscal year 2025, up 11% year-over-year. The company secured a $690 million remaining performance obligation backlog, driven by major contracts with NATO, the German government, and multiple U.S. defense agencies. In 2025, Planet achieved its first full year of adjusted EBITDA and free cash flow profitability.
Marshall sees artificial intelligence as the catalyst that transforms Planet from an imagery company into a data platform. He calls the vision “Queryable Earth” — the ability to ask a question about any place on the planet and get an answer derived from daily satellite data and AI analysis. In November 2025, he told Axios that AI will “change the status quo” by “democratizing, scaling, and accelerating the ability to extract information out of satellite data."
"Our purpose is helping us to take care of this spacecraft — one spacecraft — called the Earth.” — Will Marshall
What Comes Next: Searching the Surface of the Earth
Planet launched 72 new SuperDove satellites in 2025 alone, continuing to refresh its constellation with improved sensors and faster revisit rates. The company’s market cap crossed $9 billion in early 2026. Marshall has stated that 2026 is “a critical inflection point in AI for space” — the year when machine learning models become capable of processing planetary-scale imagery in near real time.
Fifteen years after leaving NASA with two colleagues and a garage, Marshall has built the infrastructure to watch the entire Earth change, every day, in granular detail. The kid who studied quantum mechanics under Roger Penrose ended up building something far more tangible — a living, searchable record of the planet’s surface. The cameras never stop.
