Spangle, a Seattle-based artificial intelligence startup has completed a fifteen million dollar Series A funding round, elevating its post-money valuation to one hundred million dollars. The company, founded by former technology executives from Amazon and Bolt, specialises in developing what it describes as an agentic infrastructure layer for the digital retail sector. According to a report by TechCrunch, the all-equity investment was led by NewRoad Capital Partners, with continued participation from several venture capital firms including Madrona and Streamlined Ventures. This latest influx of capital brings the total funding for the venture to twenty-one million dollars, following an initial seed round concluded in early 2025.
The platform is designed to address a fundamental shift in how consumers discover products online, moving away from traditional search engines toward conversational AI tools and autonomous shopping agents. Since emerging from its stealth phase, the company has secured nine enterprise clients in the high-end fashion industry, including prominent brands such as Steve Madden and Alexander Wang. As reported by Digital Commerce 360, these clients collectively manage approximately three point eight billion dollars in annual online sales. The startup’s software facilitates real-time personalisation by routing incoming web traffic through a proprietary reasoning engine that adapts to individual visitor behaviour.
Central to the company’s technical advantage is its ProductGPT model, a large-scale artificial intelligence system trained specifically on merchant data and consumer interactions. Rather than relying on static website layouts, the platform populates dynamic pages in real time based on signals such as referral sources and search intent. According to an analysis by IndexBox, traffic flowing through this system increased by an average of fifty-seven per cent month-on-month throughout late 2025. This rapid adoption has allowed the startup to quadruple its revenue run rate in the final quarter of the year, demonstrating a strong market fit for AI-native commerce infrastructure.Retailers utilising the technology have documented significant improvements in their primary performance metrics, particularly regarding the efficiency of paid advertising. Reports indicate that brands have achieved up to a fifty per cent increase in revenue per visit and a doubling of their return on ad spend. By bypassing traditional cookie-based tracking in favour of real-time contextual relevance, the platform provides a privacy-compliant method for improving average order values. This level of automation allows lean engineering teams to manage complex merchandising tasks that previously required extensive manual oversight, reflecting a broader trend toward operational efficiency.
The success of the venture coincides with a structural reset in the global e-commerce market, which is projected to approach nearly seven trillion dollars by the end of 2026. Industry strategists suggest that competitiveness is increasingly defined by the speed at which companies can integrate autonomous digital workers into their existing network stacks. As reported by Cisco, the transition from simple AI operations to fully agentic systems is expected to be a defining characteristic of the current fiscal year. This shift allows retailers to maintain brand consistency while delivering the hyper-personalised experiences that modern shoppers have come to expect from digital interfaces.
With a current staff of approximately six full-time employees, the startup plans to use its new capital to scale its engineering and sales organisations. The investment will primarily fuel research and development aimed at enhancing the reasoning capabilities of its AI models and expanding its agentic infrastructure. This focus on research is intended to keep the company at the forefront of the emerging agentic commerce sector, where autonomous agents may soon influence hundreds of billions in consumer spending. The lean nature of the organization highlights how advanced automation allows software companies to achieve significant enterprise scale with a fraction of the traditional headcount.
