Professional Overview
Spencer Hewett is the Founder and Chief Executive Officer of RADAR, a New York-based startup specializing in advanced retail technology. He launched RADAR in 2017 with the vision to revolutionize inventory management in brick-and-mortar retail through a proprietary hardware and software platform combining RFID (Radio Frequency Identification) and computer vision technologies. Spencer's leadership has been critical in positioning RADAR as a notable innovator in retail tech, with the company now deployed in over 500 American Eagle Outfitters (AEO) stores and expanding partnerships with multiple publicly traded billion-dollar apparel companies.
Educational Background and Early Career
Spencer Hewett initially studied Computer Engineering at Washington University in St. Louis, though he left as a sophomore after being awarded the prestigious Thiel Fellowship in 2012, a $100,000 grant program for young entrepreneurs. This fellowship enabled him to relocate to Palo Alto and focus on developing his vision of automating retail checkout and inventory management.
Hewett’s early entrepreneurial experience includes founding Shopit in 2011, a precursor company that utilized RFID tags to map store layouts. His insights into retail pain points were further shaped during an internship at eBay, where a prolonged checkout line experience inspired the creation of RADAR’s autonomous checkout and inventory tracking technologies.
Company and Technology
RADAR delivers a fully integrated hardware and software system that employs ceiling-mounted proprietary sensors equipped with RFID readers and four-camera arrays to track individual items with unprecedented accuracy. The platform achieves 99% real-time inventory accuracy with location precision down to 10 cm in 3D space, which is significantly more precise than standard industry solutions typically limited to 70-85% accuracy and meter-scale localization.
The system automates inventory cycle counts every 60 seconds, providing store associates near-instant, SKU-level visibility into product location, availability, and movement within a store. This visibility enables:
- Rapid product location for improved customer service.
- Autonomous restocking through real-time monitoring and automatic pick list generation.
- Efficient order fulfillment for omnichannel sales including BOPIS (Buy Online, Pick Up In-Store) and curbside pickup.
- Enhanced labor productivity and inventory accuracy, thereby reducing lost sales and operational costs.
RADAR’s platform reduces the dependency on handheld RFID scanners, which require manual operation and often provide inconsistent data due to human error and physical constraints. Its scalable sensor network covers approximately 500 square feet per device, simplifying deployment and lowering costs compared to dense camera grids used by competitors like Amazon Go.
Funding, Scale, and Strategic Partnerships
- RADAR has raised multiple funding rounds, including a $16 million round in early 2025 and a $30 million Series A round in mid-2023, bringing total funding to approximately $63 million.
- A forthcoming $50 million Series B round was announced in December 2024 to accelerate growth, expand customer deployments, and scale hardware production.
- The company employs approximately 13 employees, with key executives including Michael Murphy (COO), former Head of RFID at Inditex (parent company of Zara), and Adam Blair (CTO), an experienced engineer from Boeing and RFID hardware pioneer.
- RADAR maintains active partnerships with over 40 retailers in backlog and is piloting deployments with two additional Fortune 500 companies beyond American Eagle, targeting large-scale expansions in 2024.
- Investors include traditional venture capital firms and strategic retail ecosystem partners like Align Ventures and RX Ventures, supporting both financial growth and industry alignment.
Innovations, Intellectual Property, and Industry Recognition
- Spencer Hewett has filed for over 20 patents relating to RADAR’s RFID hardware, software algorithms, and integrated computer vision techniques, reflecting a strong emphasis on proprietary technology.
- In 2022, he was named to Forbes 30 Under 30, recognizing his impact on retail technology innovation.
- RADAR was listed among The Information's 50 Most Promising Startups of 2023, indicating recognition for rapid growth and industry influence.
- RADAR’s technology is recognized for facilitating operational resilience, faster store processes, and enhanced customer personalization, where future product scopes include integration with Point of Sale (POS) and Electronic Article Surveillance (EAS) systems, plus advanced just-walk-out checkout capabilities.
Strategic Vision and Market Context
Spencer Hewett envisions RADAR as an enabler of the Internet of Things (IoT) in retail, aiming to index and track every physical object worldwide. With retail inventory distortions causing global losses estimated at $1.9 trillion annually, RADAR addresses the critical need for real-time, actionable data in stores. The platform’s granular inventory data supports retailers’ omnichannel strategies by reducing order cancellations, split shipments, and labor inefficiencies.
Hewett emphasizes that RADAR’s ability to merge AI, RFID, and computer vision will drive the next evolution of retail by:
- Delivering personalized, convenience-driven in-store experiences comparable to online channels.
- Enhancing store security and loss prevention through real-time alerts on theft.
- Providing predictive analytics for inventory demand and sales associate deployment.
Relevant Achievements & Recognitions
- Awarded the Thiel Fellowship (2012), a catalyst for RADAR’s formation.
- Forbes 30 Under 30 honoree (2022).
- Patent portfolio exceeding 20 inventions protects the company’s technological innovations.
- Recognition by industry bodies such as being a semi-finalist for the HardTech Awards (2025).
- RADAR’s scaling efforts resulted in over 500 store deployments within a major retail brand (American Eagle) in under two years.
Summary
Spencer Hewett stands out as a technically proficient and visionary entrepreneur who has successfully combined advanced engineering expertise with pragmatic business execution in the retail technology sector. His leadership at RADAR demonstrates a clear commitment to solving inventory management inefficiencies through patented sensor fusion technologies, driving measurable ROI in major retail environments. With significant funding secured and an expanding footprint among leading retailers, Spencer’s focus on integrating AI and expanding platform capabilities positions RADAR for sustained growth and disruptive impact within the evolving retail landscape.
