Tank Utility

Tank Utility is a Boston-based IoT and software company that builds remote propane and fuel tank monitoring hardware and analytics to optimize last-mile fuel delivery for homeowners and fuel marketers; it was founded in 2014 and was acquired by Generac in 2021.[2][1]

High-Level Overview

• Mission: Tank Utility uses IoT and software analytics to bring transparency and better decision-making to last-mile fuel delivery, improving the delivered-fuel experience for both propane homeowners and fuel-marketing businesses.[2]
• Product / who it serves: The company builds an LTE-enabled propane tank level monitor and companion mobile/web software that provides real-time tank level data and alerts to homeowners and fuel delivery companies (fuel marketers).[3][2]
• Problem solved: Tank Utility prevents out-of-fuel events, reduces unnecessary deliveries, and enables more efficient routing and scheduling for small-to-mid-size delivered-fuel businesses by supplying reliable remote level data and analytics.[2][3]
• Growth momentum / corporate event: Tank Utility raised venture capital (total disclosed ~$10.8M) and developed patents for tank-level monitoring, and the business was acquired by Generac Holdings in September 2021[1][1].

Origin Story

• Founders and genesis: The idea began after a weekend at a ski house where EnerNOC employees (members of the founding team) discovered an empty propane tank, inspiring a solution to avoid such outages; the team leaned on IoT and analytics to tackle the “last-mile” delivery problem.[2]
• Founding year and early evolution: Tank Utility was founded in 2014 and initially focused on providing homeowners with wireless tank monitors and apps before expanding its offering to fuel marketers and enterprise delivery optimization.[1][2]
• Early traction / milestones: The company developed multiple patents related to tank-level sensing, raised roughly $10.8M in outside capital, scaled deployments with delivered-fuel customers, and was acquired by Generac in 2021.[1][1][2]

Core Differentiators

• Data + IoT focus: Combines LTE-enabled hardware sensors with analytics and software to convert raw tank-level signals into actionable delivery decisions for carriers and homeowners.[3][2]
• Product simplicity and mobile UX: A consumer-facing monitor and smartphone app that alerts users before runouts—positioned to reduce unnecessary truck rolls and improve customer experience.[3]
• Fuel-marketer orientation: Expanded beyond homeowner devices to provide operational tools and analytics tailored to fuel marketers (route optimization, refill thresholds, forecasting).[2]
• Intellectual property: Holds patents for monitoring and reporting liquid levels in tanks, supporting a defensible technology position in tank sensing.[1]

Role in the Broader Tech Landscape

• Riding the IoT + edge-sensor trend: Tank Utility operates at the intersection of IoT sensors, low-power cellular connectivity (LTE), and cloud analytics—a matured stack for remote-asset monitoring that reduces manual checks and enables predictive operations.[3][2]
• Timing and market forces: Demand is driven by continued interest in operational efficiency, rising logistics costs, and the need to serve dispersed, connectivity-challenged customers (rural propane users) more reliably.[2]
• Influence on the delivered-fuel ecosystem: By providing telemetry and analytics, Tank Utility helps traditional fuel-marketers modernize operations, reduce costs, and improve consumer experience—accelerating digital transformation in an industry that has been slow to adopt connected solutions.[2]

Quick Take & Future Outlook

• Near-term: Under Generac ownership, Tank Utility’s technology is positioned to integrate with a broader set of home-energy and backup-power offerings—potentially expanding use cases beyond propane to other liquid fuels and fuel-adjacent services given Generac’s product footprint.[1]
• Medium-term trends that will shape trajectory: Continued decline in the cost of cellular IoT, improvements in rural connectivity, and greater expectations for predictive and automated service will favor companies that can reliably deliver sensor-to-software solutions for decentralized assets.[3][2]
• Potential impact: If Tank Utility’s telemetry and analytics scale across more fuel-marketer customers and tie into broader home-energy platforms, it can materially reduce runouts and delivery inefficiency across millions of locations served by delivered fuels.[2][1]

Quick take: Tank Utility is a focused IoT/software player that turned a simple, high-value consumer pain (running out of propane) into an operations product for fuel distributors; acquisition by Generac gives it a stronger channel and product integration runway to extend its impact across home and fuel-energy markets.[2][1]
