Media planning, audience development, and ROI analytics built around Agile Mix Modeling

Ars X Machina is an independent, female-founded media and analytics agency based in San Francisco, certified through WBENC as a women-owned business. Its client work spans distinct awareness and growth challenges: Shipt needed to build brand recognition quickly against larger competitors, Glassdoor needed a campaign to attract job seekers, Nutanix lacked a strong brand presence, and Sierra Nevada set out to grow sales among the craft beer audience.

Work centers on media planning and buying, audience development, and budget analysis, supported by an analytics and data science practice built around Agile Mix Modeling™, the agency's approach to tracking return on media investment. Campaigns run through this modeling framework, connecting planning decisions to spend analysis rather than treating the two as separate steps.

Staff experience at Ars X Machina averages 10 years, and client relationships average more than five years in tenure, reflecting an agency structured around ongoing media and analytics work rather than short-term campaigns.
