Piston Raises $15M Series A Led by FPV Ventures to Scale Cardless Fleet Payments Network

Piston Closes $15M Series A

Piston, a cardless payments network connecting commercial fleets with gas stations and convenience stores across the United States, has raised a $15 million Series A round. The funding was led by FPV Ventures, with participation from Pear VC and Spark Capital.

The round was announced on September 10, 2026, and brings Piston's total disclosed funding to the Series A stage.

What Piston Does

Piston operates a cardless payments network purpose-built for commercial fleets. Its mobile authorization technology is embedded directly into the point of sale, tying every fuel purchase to a specific driver and vehicle in real time.

That architecture addresses two persistent problems in fleet fueling:

• Card skimming fraud. Because transactions are authorized through mobile technology rather than physical cards, the card-skimming vector that plagues traditional fleet cards is eliminated.
• Transaction costs. By connecting fleets and merchants directly through the point of sale, Piston aims to cut costs on both sides of the transaction.

The company was founded by former fleet operators, a background that shaped a product designed around the operational realities of running commercial vehicles rather than retrofitting consumer payment rails.

Traction and Footprint

Piston says its network is live at more than 2,000 stations across 48 states. That footprint gives the company a meaningful presence in the U.S. fueling market while leaving room for further station-level expansion.

The company is also extending beyond fuel into broader logistics payments infrastructure, signaling an ambition to become a wider payments layer for commercial fleets rather than a single-purpose fueling tool.

Why This Round Matters

The Series A gives Piston capital to pursue several fronts simultaneously: deepening its station network, expanding into adjacent logistics payments categories, and competing for merchant and fleet relationships in a market where incumbents rely on legacy card infrastructure.

The investor syndicate reflects a mix of early-stage and growth-oriented backers. FPV Ventures led the round, with Pear VC and Spark Capital participating.

Acquisition Angle

For acquirers, Piston sits at an interesting intersection:

• Closed-loop payments infrastructure. The network connects two distinct constituencies — fleets and fuel merchants — through proprietary authorization technology embedded at the point of sale.
• Real-time data linkage. Every transaction is tied to a specific driver and vehicle, producing a structured data asset that generic payment processors do not capture.
• Geographic reach. Live coverage across 48 states and more than 2,000 stations represents a distribution footprint that would be costly to replicate from scratch.
• Expansion vector. The stated move into broader logistics payments suggests a platform trajectory rather than a point solution.

Payments networks with two-sided merchant and enterprise relationships are frequently strategic acquisition targets for processors, fuel card issuers, and logistics software platforms seeking to own the transaction layer.

Company Snapshot
