The man who sold a $3.2B company, looked at planet Earth, and said: "We can fix this."
CEO & Co-Founder of Charm Industrial. Former CEO of Segment. MIT aerospace engineer. He converts farm waste into a thick dark liquid, injects it into the earth, and calls it barbecue sauce.
Charm Industrial
Profile
Peter Reinhardt has now built two companies from scratch. The first one tracked customers. The second one is trying to track carbon - and then bury it permanently underground.
Most people who sell a company for $3.2 billion go buy a boat. Reinhardt started reading papers on pyrolysis. The pivot from Segment to Charm Industrial is not a story about a founder who ran out of problems to solve. It's the story of a founder who encountered a problem he couldn't delegate to someone else.
The origin moment is embarrassingly specific. In 2016, Reinhardt purchased carbon offsets on behalf of Segment. Then he looked into what he'd actually bought. "Crap, pretty sure we got scammed," he wrote later. That feeling - the gut punch of paying for something that didn't exist - stayed with him. By 2018, he'd co-founded Charm Industrial with two engineers he knew from Planet Labs connections: Shaun and Kelly Kinetic.
The business they built is genuinely strange and genuinely hard. Charm designs and operates a fleet of truck-mounted fast pyrolyzers - essentially mobile kilns that heat agricultural waste (corn stover, wheat straw, forest slash) to extreme temperatures in the absence of oxygen. The result: a dense, dark liquid that Reinhardt calls "barbecue sauce." It's carbon-rich, it's stable, and unlike a tree or a forest, it doesn't decompose and release CO2 back into the atmosphere when something goes wrong.
The bio-oil gets injected into underground geological formations. It stays there. Permanently. That's the whole idea: take carbon that plants pulled out of the air, turn it into something that won't off-gas for geological timescales, and put it back underground near where fossil fuels came from.
What makes Charm's approach different from the crowded field of carbon offset products isn't just the permanence - it's the receipts. The company has delivered 6,200+ verified tons of removal. Stripe signed a $53 million agreement for 112,000 tons. JPMorgan Chase committed to 28,000+ tons. Meta and Microsoft are in the customer list. These are not promises. These are contracts backed by measured, third-party-verified deliveries.
Reinhardt is not the kind of founder who describes what he does in abstract terms. He describes it as pumping barbecue sauce underground. He says his mission is to return the atmosphere to 280 parts per million CO2 - the pre-industrial baseline. That number appears in nearly every interview. It is not a target the world has agreed to hit. It is the target he has decided to aim at.
To understand where Reinhardt is now, it helps to know how Segment actually started. He and his MIT dormitory neighbors - Calvin French-Owen, Ilya Volodarsky, Jean Lafleur, and Ian Taylor - applied to Y Combinator in 2011 with an idea for classroom lecture software. It failed. Nobody wanted it. But while they were building the thing nobody wanted, they created an internal analytics library that developers kept asking about. That library - Analytics.js - became Segment. The company grew to 600+ employees, $200M+ ARR, and a $3.2 billion acquisition by Twilio in 2020.
The path from MIT aerospace engineering to software infrastructure to industrial climate technology is not an obvious one. But Reinhardt describes his decision-making through a consistent lens: identify the hardest, most important problem, and run directly at it. He credits Y Combinator for the advice: "Run straight at problems." He has applied it literally.
"Our mission is to return the atmosphere to pre-industrial carbon dioxide levels of 280 parts per million CO2. And the way we do that is we pump barbecue sauce underground."- Peter Reinhardt, CEO & Co-Founder, Charm Industrial

Fun Facts
Charm's original technology pitch uses food language deliberately. "Barbecue sauce" is sticky, dark, and permanent - much more intuitive than "carbon-rich bio-oil pyrolysis product."
Reinhardt's personal domain is rein.pk - a domain hack using Pakistan's country code. His Twitter handle is @reinpk. Same logic. He registered it years before it was cool.
Charm's mobile pyrolyzers are truck-mounted because the biomass is heavy and dispersed. The machines travel to the fields - corn stover, wheat straw, forest slash - not the other way around.
He chairs Revoy - a company that converts diesel semi trucks into 80-95% cleaner vehicles using electric trailer add-ons. The efficiency goes from ~7 mpg to the equivalent of 120 mpg.
Segment started as a failed classroom lecture tool for Y Combinator. The actual product emerged from an internal analytics library that developers kept asking about while the main product flopped.
Charm is also developing a pathway for fossil-free steelmaking using bio-oil as a hydrogen carrier. Steel is one of the hardest industries to decarbonize - Reinhardt is working on it in parallel.
