Waterdrop Digital

What Waterdrop Digital does

Waterdrop Digital is a digital advertising brand and operating division of Amaturo Sonoma Media Group (ASMG), a privately held local media company based in Santa Rosa, California. Founded in 2015 and employing 51–100 people, it provides custom digital advertising services — including paid social, paid search, display, streaming audio, and creative/analytics — to local businesses in the North Bay and Sonoma County region. Its core platform supports location-based and behavioral targeting, enabling advertisers to reach audiences based on geography and buying habits across social media, streaming audio, and thousands of display websites.

The company's principal structural asset is its integration with ASMG's media portfolio: eight radio stations (KZST, KSRO, Froggy 92.9, Hot 101.7, 99.1 The Bull, 97.7 The River, 102.7 The Wolf, 93.7 Jazzy) reaching 250,000 weekly listeners, plus associated station websites, mobile app inventory, and social media channels. This allows Waterdrop Digital to bundle broadcast and digital inventory into multi-channel campaigns for SMB advertisers. Distribution is direct via ASMG's sales team; no self-serve portal, public API, mobile app, or disclosed pricing exists.

Waterdrop Digital operates as a non-listed, privately held division of ASMG. There is no disclosed separate funding, capitalization, or independent financial reporting; revenue, headcount trends, and customer-level data are not publicly available. The business is geographically constrained to the North Bay/Sonoma County region and serves a fragmented SMB client base with no named enterprise logos.
