The Subscription Economy has grown dramatically in the past decade, and is anticipated to almost triple again - from $635B to $1.5T - by 2025 [UBS]. But this growth is not just important economically. It is also dramatically changing the way that brands engage with consumers. The Subscription Economy enables brands to untether themselves from the established distribution channels and they have historically been stuck in, and to transcend transactional business models. The opportunity: deep, direct relationships with their customers, based on a long-term allegiance. And for consumers, this translates to much more choice, a dramatically better product experience, and a deeper connection with the brands they love. ‍ The fuel for this new world is data. Brands need to deeply understand consumer behavior to survive and thrive in the Subscription Economy. Enter Antenna. Get to know our data on our https://www.antenna.live/insights.

Vemba is an operating system for video distribution - the most dynamic platform ever introduced to the marketplace - allowing producers and publishers to transact more easily and simplify the complex editorial and business workflows associated with legacy syndication models. Media companies use Vemba to broadly scale their video audience with easy syndication to a multitude of diverse OTT apps and connected platforms. Vemba also powers direct-to-publisher syndication programs for organizations like Vice, Conde Nast and others. Vemba has created the first player agnostic technology solution for the industry, allowing publishers to integrate 3rd-party video content and advertising within their preferred editorial process and existing video workflow. Producers maintain better control of their content with Vemba, and publishers can feature original and complementary video without needing to adjust for unwieldy 3rd-party players or advertising restrictions. With Vemba at the intersection of every transaction, both content owner and publisher receive real-time analytics on the performance of both video and advertising, regardless of OVP, video player, ad server, or CDN. Vemba is HQ’d in Toronto and has an office in New York City.
