Throne Labs develops smart, accessible restrooms for public spaces. These advanced units integrate multiple sensors, running water, and real-time user cleanliness ratings to deliver a superior public sanitation experience. The company establishes a distributed network of these technologically enhanced portable facilities, aiming to elevate the standard of public hygiene infrastructure.
Founded in 2020 by Jessica Heinzelman and Fletcher Wilson, Throne Labs emerged from a shared recognition of the pervasive issues plaguing public restrooms. Their core insight was that modern technology could fundamentally transform these essential facilities, making them significantly cleaner, more accessible, and economically viable for a wide range of applications.
Throne's product serves a broad spectrum of public space operators and their constituents, addressing a critical societal need for dignified and reliable public hygiene options. The company's long-term vision centers on reimagining the public restroom infrastructure, establishing a new standard for quality and availability that leverages innovation to enhance urban living and public health.

# High-Level Overview
Throne Labs is a venture-backed startup that designs and operates smart, prefabricated public restrooms to address America's critical shortage of clean, accessible bathroom facilities.[1][2] Founded in 2020, the company has raised $15.98M to date and operates "Thrones"—technology-enabled restrooms equipped with real toilets, sinks, climate control, and sensor networks—deployed across U.S. cities, parks, and transit stations.[1] The company solves a universal but overlooked problem: the difficulty of finding dignified, sanitary public restrooms when needed. Rather than selling hardware, Throne operates on a "bathroom as a service" model, contracting with municipalities and transit authorities to manage restroom operations end-to-end, handling maintenance, cleaning, and user accountability.[4]
The problem Throne addresses is substantial. The U.S. ranks 30th globally in public restroom availability, with only 8 toilets per 100,000 people, creating public health challenges and operational burdens for cities.[4] Throne's approach combines modern technology—solar power, off-grid capability, real-time sensors, and app-based access—with intentional design to make public restrooms cost-effective, scalable, and genuinely pleasant to use. The company launched its first permanent installation in March 2023 in Washington, D.C.'s Capitol Riverfront neighborhood and has since expanded across the country.[2]
# Origin Story
Throne Labs was founded in 2020 by co-founder and CEO Fletcher Wilson, whose personal experience with digestive health challenges sparked curiosity about public restroom access in America.[2] Rather than dismissing the problem as trivial, Wilson investigated and discovered the issue was far more universal than he initially realized—affecting delivery drivers, runners, parents, and countless others navigating daily life without reliable access to clean facilities.[2]
The founding team brought complementary expertise in engineering, entrepreneurship, and social impact.[2] After several years of iteration and testing, they launched their first permanent Throne in March 2023, validating the market and proving the concept could work at scale.[2] Today, the company has grown to over 100 employees and operates across multiple U.S. markets.[2]
# Core Differentiators
# Role in the Broader Tech Landscape
Throne Labs exemplifies a growing trend of technology solving unglamorous but essential infrastructure problems. While venture capital typically gravitates toward software and consumer apps, Throne demonstrates that hardware + software + service integration can address decades-old civic failures. The company rides several favorable trends: increasing urbanization creating density-driven demand, growing awareness of public health equity, municipal budget constraints driving outsourcing, and IoT maturation making sensor networks economically viable.[4]
The timing is critical. U.S. cities face mounting pressure to address homelessness, public health, and quality-of-life issues—all exacerbated by restroom scarcity. Throne's model offers municipalities a turnkey solution without massive capital expenditure, making it politically and fiscally attractive. The company also influences the broader startup ecosystem by proving that "boring" infrastructure problems can attract serious venture funding and that solving them at scale requires blending hardware, software, and operational expertise.
# Quick Take & Future Outlook
Throne Labs is positioned to become the dominant operator of public restrooms in America, much as private waste management companies transformed sanitation. The company's $15.98M in funding and recent $9.83M raise (five months prior to December 2025) signal investor confidence in the model's scalability.[1] Key challenges ahead include expanding beyond major urban centers, managing unit economics as deployment scales, and navigating municipal procurement cycles.
The company's trajectory will likely be shaped by three forces: continued urbanization and density, growing municipal willingness to outsource non-core services, and potential policy tailwinds (e.g., federal infrastructure funding for public amenities). If Throne can replicate its Washington, D.C. success across 50+ U.S. cities, it could fundamentally reshape how Americans experience public spaces—transforming a chronic quality-of-life problem into a solved one. In doing so, Throne demonstrates that the most impactful startups don't always disrupt; sometimes they simply solve what everyone has learned to live without.
