MediaJel

MediaJel builds and operates a programmatic advertising platform focused on regulated industries such as cannabis, alcohol, gaming, politics, and sexual wellness. The company was founded in Walnut Creek, California, though the founding year and names of founders are not publicly disclosed. The platform enables advertisers to buy compliant media across display, CTV, digital out-of-home, native, search, and SEO — all coordinated through a single attribution dashboard. The firm's asset-class mix includes programmatic display, CTV, DOOH, native advertising, and search. MediaJel offers three engagement models: self-serve, full-service, and white-label for agencies. The company targets audiences using a proprietary DemoGraph audience builder that accesses 196M+ verified profiles, and incorporates attention-based performance metrics from Adelaide's AU insights. Geographic footprint is primarily North America, with a focus on US state-by-state compliance. Named portfolio companies or co-investors are not disclosed. MediaJel's team size and total professionals are not publicly available. The firm has no disclosed additional offices beyond Walnut Creek. No adjacent vehicles — such as philanthropic foundations or operating companies — are publicly associated with the firm. Recent activity is not available. MediaJel's structural differentiator is its regulatory compliance automation. The platform automatically implements age-gating, creative restrictions, and state-by-state policy adherence — a feature set that competing generalist ad platforms rarely offer. This compliance-first architecture allows advertisers in restricted verticals to access mainstream premium inventory that would otherwise be blocked.
