Sean Turner

Co-Founder and CTO Swiftly

Last Reviewed: September 19, 2026

Executive Summary

Sean Turner is co-founder and chief technology officer of Swiftly, a retail technology company built around a specific asymmetry: online retailers know exactly who bought what, when and after seeing which advertisement, while physical grocery chains — which still account for the overwhelming majority of grocery spending — largely do not. Swiftly’s platform closes that loop for brick-and-mortar retailers, wholesalers and consumer brands, unifying transaction and product data, automating merchandising workflows, and running measurable retail media campaigns against it. Turner co-founded the company with Henry Kim and Karen Ho, and came to it from Symphony Commerce, where he led product for a direct-to-consumer e-commerce platform, and before that from Microsoft, where he spent years in search advertising, speech recognition and mobile payments.

Career Highlights

• Co-founded Swiftly with Henry Kim, now chief executive, and Karen Ho, now VP of Engineering, and has served as chief technology officer since.
• Swiftly reached unicorn valuation in 2022 on the back of a $100 million round, and has raised roughly $220 million in total from investors including BRV Capital Management and Wormhole Capital.
• Built the technical foundation for what the company describes as the industry’s largest proprietary retail dataset: live transactions, nine million products, and closed-loop campaign outcomes across 33,000 stores.
• As Head of Product at Symphony Commerce, built the e-commerce platform that let major consumer-packaged-goods brands run direct-to-consumer businesses, and drove the company’s move upmarket into enterprise accounts.
• At Microsoft, worked as a technology lead on Bing Product Ads, Cortana’s speech recognition, the Windows 8 News app, and the Starbucks mobile payment experience on Windows Phone.

Professional Journey

Turner studied computer engineering and computer science at the University of Southern California and began his career at Microsoft, where the range of what he worked on is more interesting than any single product. Bing Product Ads is an advertising auction and relevance problem; Cortana’s speech recognition is a machine-learning and latency problem; the Starbucks payment experience on Windows Phone is a transaction and retail-integration problem. Taken together they map fairly precisely onto the three things Swiftly would later have to do at once — target advertising, make sense of messy retail data, and sit inside a merchant’s actual payment and loyalty flow.

He moved from Microsoft to Symphony Commerce as Head of Product. Symphony built the commerce platform that let large consumer-packaged-goods brands stand up their own direct-to-consumer channels, and Turner was responsible for taking the product to enterprise-scale customers. That work put him on the brand side of the same question Swiftly now answers from the retailer side: a CPG brand selling direct gets full visibility into its customers, while the same brand selling through a supermarket gets almost none.

Swiftly was founded to import that visibility into physical retail. Sources disagree on the year — commonly cited dates are 2017 and 2018 — but the founding team is clear: Turner, Henry Kim as chief executive, and Karen Ho leading engineering, all with commerce-platform backgrounds. The product began as a way of giving supermarkets the digital capabilities of an online retailer, in the form of a shopper app, digital circulars and loyalty, and evolved into a retail media network: once a chain’s transaction data, product catalogue and shopper identity sit in one place, brands can buy targeted campaigns against it and see what those campaigns actually caused at the till.

The commercial trajectory reflected that broadening. Swiftly raised a $100 million round in 2022 that made it a Seattle unicorn, with total funding of roughly $220 million from investors including BRV Capital Management and Wormhole Capital, and expanded out of grocery into home goods, electronics, fashion and sporting goods. More recently the company has repositioned around artificial intelligence, describing itself as an AI platform purpose-built for retail — a framing that rests on the dataset Turner’s team assembled rather than on a change of business.
