Professional Journey

Glueck’s first company was site59.com, a last-minute travel deals site. It grew past $100 million in sales and was acquired by Travelocity. He stayed on, and a 2003 Travelocity release filed by its parent Sabre quotes him as vice president of packaging, promoting trips bundled from several parts. He went on to serve as Travelocity’s Chief Marketing Officer for six years, during which, by Salvo’s account, the company’s global sales rose from $3.5 billion to $11 billion.

He then became Chief Executive Officer of Skyfire, which worked on improving video on mobile networks. In 2014 he joined Foursquare as Chief Operating Officer, and in early 2016 he succeeded its founder, Dennis Crowley, as chief executive. Glueck signed Foursquare’s January 2016 Form D in that capacity. His tenure covered the company’s turn from a consumer check-in app to a business selling location data and context-aware software to retailers, restaurant chains and other large brands. In 2019 Foursquare acquired Placed, and that December the company announced that Placed’s founder, David Shim, would succeed Glueck as CEO at the end of the year.

Salvo Health grew out of a personal loss. His company biography says that after he and his wife lost a pregnancy late in term, he saw how slowly medicine adopts advanced and genetic diagnostics, and he had wanted to build a data-driven healthcare company ever since. The pandemic shift in how patients expected to receive care gave him the opening. Salvo was incorporated in 2021 and launched with gastrointestinal conditions first.

The model changed as the company grew. Salvo now describes itself as a hybrid platform that partners with independent gastroenterologists rather than competing with them. The practice keeps the in-person visit, and Salvo supplies a care team, an app, monthly virtual visits and adherence data fed back into the practice’s records. Most of its patients are women. Salvo raised a $4 million extension in June 2025, when it had 700 GI physicians signed. In January 2026 it announced an $8.5 million Series A with about 800 gastroenterologists under agreement, roughly 16% of the independent GIs in the US, and access to more than 1.1 million patients across ten states. The company said the money would go to AI engineering and to national hiring of dietitians, behavioral health staff and nurses.

He lives in Westchester, New York.
