Mobile fuel delivery and fleet energy services

Frank Mycroft is the co-founder and CEO of Booster, a mobile energy-delivery company that refuels vehicles where they are parked rather than at a filling station, serving commercial fleets and enterprise campuses across the United States. An aerospace engineer by training with earlier stints at Boeing, NASA, McKinsey and the asteroid-mining venture Planetary Resources, he co-founded the company in 2015 with Diego Netto and Tyler Raugh and has positioned it as an on-ramp to lower-carbon fuels for fleet operators.

Executive Summary

Frank Mycroft is the co-founder and CEO of Booster, a mobile energy-delivery company built on the proposition that the filling station is an unnecessary step. Booster’s purple tankers refuel vehicles where they are already parked — commercial fleet yards, enterprise campuses, office lots — so that a fleet driver begins a shift with a full tank rather than losing time to a detour. Mycroft co-founded the company in 2015 with Diego Netto and Tyler Raugh, and has raised more than $200m for it across nine rounds, including a $125m Series D in 2022. His route into fuel logistics was oblique: an engineer trained at Princeton, Stanford and Harvard, he worked at Boeing and NASA and at Planetary Resources, the asteroid-mining venture, as well as at McKinsey, before deciding that the more tractable problem was terrestrial. The company’s strategic argument has shifted with its customer base — originally a commuter convenience, it became a fleet-operations service during the pandemic, and is now positioned as a distribution channel for renewable and lower-carbon fuels that would otherwise have no retail pathway.

Career Highlights

  • Co-founded Booster in 2015 with Diego Netto and Tyler Raugh, and has led it as CEO since.
  • Raised more than $200m across nine rounds, including a $56m Series C in 2019 and a $125m Series D announced in May 2022, led by Rose Park Advisors with Chaac Ventures, Equinor Ventures, Mitsubishi Corporation and Thayer Ventures participating.
  • Delivered over three million gallons of fuel in the company’s first 18 months across the San Francisco Bay Area and Dallas-Fort Worth.
  • Built an enterprise customer base that has included Cisco, Oracle, eBay, PepsiCo and Facebook, and expanded into Seattle, Washington DC and Maryland.
  • Repositioned the company from commuter refueling to commercial fleet refueling during the pandemic, when office parking lots emptied.
  • Previously held engineering, consulting and leadership roles at Boeing, NASA, Planetary Resources and McKinsey & Company.
  • Appeared on CNBC in 2022 on renewable-fuel accessibility and the fleet refueling model, and discussed Booster’s growth-to-profitability transition on the 20VC podcast.

Professional Journey

Mycroft trained as an engineer, taking a Bachelor of Science in Engineering at Princeton in 2007, two master’s degrees at Stanford in 2009 and 2010, and an MBA at Harvard in 2012. His early career was in aerospace and space systems — engineering, consulting and leadership roles at Boeing, work with NASA, and a period at Planetary Resources, the company that set out to mine asteroids for water and metals. He also spent time at McKinsey & Company. The through-line is less about any one industry than about the economics of moving a resource to where it is needed, which is what Planetary Resources was ultimately about and what Booster is about at a much shorter range.

He co-founded Booster in 2015 with Diego Netto and Tyler Raugh. The initial proposition was a consumer-adjacent one: commuters parked their cars at large employer campuses for eight hours a day, and that idle time could absorb a refueling visit that otherwise cost them a detour. Booster built an app, a fleet of branded tankers and the regulatory and safety apparatus needed to dispense fuel outside a retail forecourt. Growth was fast — over three million gallons delivered in the first 18 months across the Bay Area and Dallas-Fort Worth — and the customer list filled with large technology and consumer employers including Cisco, Oracle, eBay, PepsiCo and Facebook. Funding tracked the expansion, from a $3.1m first round in 2015 through a $9m Series A in 2016 backed by Maveron, Madrona, Version One and RRE, $20m in 2017 led by Conversion Capital, and a $56m Series C in 2019.

The pandemic removed the original customer overnight. With offices empty, the commuter parking lot ceased to be a place where cars sat all day, and Mycroft moved the company towards commercial fleets, where the same logic held more strongly and the economics were better: a fleet operator refueling on site avoids sending every vehicle on a round trip, and the value is measured in driver hours rather than personal convenience. That repositioning is what the company raised against in May 2022, when it announced a Series D of more than $125m led by Rose Park Advisors with new investors including Equinor Ventures and Mitsubishi Corporation — both strategic energy participants rather than pure financial backers.

The second half of Booster’s argument under Mycroft is decarbonization. Renewable diesel and other lower-carbon fuels face a distribution problem, because retail forecourts are slow and expensive to convert. A mobile delivery network can in principle carry whatever is in the tanker, which lets a fleet switch fuel without waiting for infrastructure to be rebuilt around it. Mycroft has made this case publicly, including on CNBC in 2022, and has framed the company as an energy-transition business rather than a convenience one. He has also spoken, on the 20VC podcast, about the harder internal transition from growth-at-all-costs to profitability.
