A Chicago-based startup called AeroVenture announced Wednesday that it has raised $200 million in Series B funding to develop technology that will “harvest, bottle, and monetize” the city’s legendary wind, which the company’s founders describe as “the most underutilized natural resource in the American Midwest.” According to the company’s own projections — which were presented on a slide titled “The Airconomy” — Chicago’s wind represents a $14.3 trillion “total addressable market,” a figure arrived at by multiplying the city’s average wind speed by the current price of Bitcoin and then, presumably, believing very hard.

The round was led by Lakefront Capital Partners, with participation from Windward Growth Equity, Prairie Ventures, and what the company described only as “a consortium of very windy investors.” AeroVenture’s valuation now stands at $1.4 billion, making it the first Chicago startup to achieve unicorn status based entirely on moving air. A venture analytics firm notes this places AeroVenture’s per-gust valuation at roughly $4,200, or approximately 11 times the cost of a deep-dish pizza, adjusted for wind chill.

“For over a century, Chicago has been called the Windy City, and for over a century, that wind has just been blowing around for free like some kind of atmospheric freeloader,” said CEO and co-founder Derek Lundquist, 29, during a press event on the rooftop of the company’s West Loop headquarters, where three attendees lost their hats. “We’re going to change that. We’re building the end-to-end vertical platform for atmospheric asset monetization.” He then paused, visibly pleased with himself, and added, “We’re disrupting air.”

AeroVenture’s proprietary technology, which Lundquist calls the “AeroMesh,” is a network of lightweight capture panels that the company plans to install on buildings throughout the Loop. The panels allegedly trap and compress wind into portable canisters, which can then be sold for various applications including “artisanal air experiences,” “premium ventilation services,” and what the company’s 83-page pitch deck — subtitled “Series B: A Breath of Fresh Capital” — describes as “luxury breathing.” A supplemental appendix outlines plans for a subscription tier called “AeroVenture Platinum,” which offers customers “curated seasonal wind profiles” for $29.99 a month.

Skeptics in the scientific community have been vocal. “This is, and I cannot stress this enough, not how wind works,” said Dr. Michael Prentiss, a professor of atmospheric science at Northwestern University. “You cannot ‘bottle’ wind any more than you can bottle disappointment — though I suppose watching this company’s investors try will come close.” He noted that AeroVenture’s core technology appears to be “a net and a jar,” and that their white paper contained the phrase “paradigm-shifting air capture synergy” fourteen times and zero peer-reviewed citations. “I’ve been studying atmospheric dynamics for thirty years,” he added. “This is the first time I’ve wanted to retire.”

Despite the criticism, AeroVenture says it has already secured pilot partnerships with several major Loop office buildings and has begun pre-sales of its flagship consumer product, “Chicago Breeze,” a canister of compressed Lake Michigan air priced at $47.99. “We sold out our first run of 10,000 units in 48 hours,” Lundquist said. “Mostly to people in Los Angeles.” Internal company metrics obtained by this publication show that AeroVenture tracks customer engagement using a proprietary KPI it calls “Breaths Per User Per Quarter,” or BPUPQ, which it reports has grown 340% month-over-month, a statistic that appears to measure how often people open the canister and inhale.

The company plans to begin full-scale wind harvesting operations by fall 2026, pending approval from the city’s Department of Planning and Development, which sources say is still trying to determine whether wind is technically a zoning issue. In the meantime, AeroVenture has posted 17 open positions on LinkedIn, including “VP of Wind Strategy,” “Chief Breeze Officer,” and “Senior Director of Atmospheric Stakeholder Alignment.” All require a minimum of eight years of experience in wind.
