John Backus took PROOF Acquisition Corp I public as a $276M enterprise SPAC in 2021, merging with drone operator Volatus Aerospace in 2023.
PROOF Acquisition Corp I
PROOF Acquisition Corp I formed in 2021 as a special purpose acquisition company sponsored by an affiliate of PROOF.vc, the early-stage venture firm John Backus co-founded. The vehicle raised $276 million in its December 2021 initial public offering, pricing 24 million units at $10 each with an additional 3.6-million-unit overallotment option. Backus, who previously held senior roles at Atlantic Capital Group and founded the Draper Atlantic venture fund, served as Chairman and CEO. The SPAC's board included former executives from SAP NS2, Palantir, and the CIA's venture arm In-Q-Tel. The SPAC targeted enterprise technology companies with demonstrated revenue, specifically those enabling digital transformation across sectors that included cybersecurity, artificial intelligence, financial technology, and aerospace. In April 2023, PROOF Acquisition Corp I announced a definitive business combination agreement with Volatus Aerospace Corp., a Canadian commercial drone services and equipment provider. Volatus operated divisions serving infrastructure inspection, public safety, and defense logistics, with a fleet of over 300 aircraft and training programs certified by Transport Canada. The deal valued Volatus at approximately $200 million and included a concurrent PIPE financing. Shareholders approved the merger in August 2023, and the combined entity began trading as Volatus Aerospace on the OTC Markets under ticker TAKOF. The pre-merger SPAC was managed by a lean structure: Backus and CFO Todd Kline anchored the sponsor entity, PROOF Acquisition Sponsor I LLC. PROOF.vc itself, the underlying venture franchise, managed roughly $150 million across early-stage enterprise and deep-tech investments (per SEC Form ADV, 2021) from offices in Reston, Virginia and San Francisco. August 2023: Shareholders approved the merger with Volatus Aerospace, completing the de-SPAC process (per the firm's official communications, August 2023). The firm's post-merger focus shifted entirely to operating Volatus, effectively ending the SPAC's standalone vehicle lifecycle. PROOF Acquisition Corp I distinguished itself from other 2021-vintage enterprise SPACs through its sponsor's operating pedigree in government technology. Backus and his network had spent decades inside the national-security technology ecosystem — Draper Atlantic's portfolio included Palantir and In-Q-Tel alumni — which shaped a sourcing funnel tilted toward dual-use technology companies with existing government revenue. Board member Michael Basla, a retired Air Force major general and former SAP NS2 executive, reinforced the defense-contracting expertise embedded in the sponsor group.

Frequently asked questions
What transaction did PROOF Acquisition Corp I ultimately complete?
The SPAC merged with Volatus Aerospace Corp., a Canadian commercial drone services company, in August 2023. Volatus operates drone fleets for infrastructure inspection, public safety, and defense logistics. The combined entity trades on OTC Markets under the ticker TAKOF.
Who ran investment decisions at PROOF Acquisition Corp I?
John Backus served as Chairman and CEO, leading the sponsor entity alongside CFO Todd Kline. Backus brought venture experience from PROOF.vc and the Draper Atlantic fund. The board included technology and defense-sector veterans, but Backus held final decision-making authority on the target selection.
How is PROOF Acquisition Corp I related to PROOF.vc?
The SPAC was sponsored by an affiliate of PROOF.vc, the early-stage venture firm Backus co-founded. The sponsor entity, PROOF Acquisition Sponsor I LLC, was distinct from the venture fund's limited partnership structure. PROOF.vc itself managed approximately $150 million across enterprise and deep-tech startup investments as of 2021.
What was the SPAC's original investment thesis?
The SPAC targeted enterprise technology companies with proven revenue in sectors including cybersecurity, artificial intelligence, fintech, and aerospace. The sponsor's defense and government-technology network oriented the search toward companies serving dual-use markets — those with both commercial and government contracts.
Does the firm still operate as a SPAC sponsor today?
No. Following the August 2023 merger with Volatus Aerospace, the vehicle completed its lifecycle. The sponsor group has not filed for a subsequent SPAC as of early 2026. The operational focus is now entirely on Volatus Aerospace's drone services business.
