About Sestra Systems

Sestra was founded by Lev Volftsun, a serial entrepreneur who has sold two technology companies to Cisco Systems and a third to Metaswitch, with a total accumulated value of over $1B. Our mission is to become the gold standard for beverage dispensing by bringing IoT connectivity to on-tap dispensing and serving the perfect pour, delivering revolutionary loss prevention to customers serving draft beverages (beer, wine, cocktails, cold brew coffee, etc.). Our patented pour control technology ensures that each and every glass of beer, wine or mixed drink is poured to the exact volume and temperature specified virtually eliminating costly over-pouring. Our hands-free, push-to-pour dispensing increases speed of service, eliminating long lines and increasing revenues during the busiest service periods. More importantly, our connected devices record all events and sync with the cloud to provide valuable real-time analytics and remote administration capabilities to our customers.

Sestra's smart dispensing solutions are installed as mission-critical applications within iconic sports venues, cultural centers, hotels and restaurants across the country. The Washington Nationals, Kennedy Center, Warner Theater, Lincoln Center, Greenbrier Resort and Longwood Gardens are just a few of our local clients.
