Resonate launches Ignition to help independent agencies compete with $50B holding companies using AI and predictive data

Resonate has launched Ignition, a programme designed to help independent and mid-sized agencies compete with larger holding companies through AI-powered consumer intelligence and activation capabilities. The platform provides agencies with agentic workflows, first-party data solutions, proprietary audience products and end-to-end intelligence tools. The programme addresses the structural disadvantage independent agencies face against holding companies that have invested billions in proprietary data infrastructure. Ignition enables agencies to move from consumer research to media activation and campaign measurement in days rather than months. Early results show agency partners achieving a 50% increase in return on ad spend and a 23% decrease in cost per conversion compared to other third-party data sources. The platform aims to help agencies open new revenue streams whilst reducing operational overhead.

Resonate and New Blue Interactive win Best Use of Analytics and machine Learning in Online Fundraising at annual Reed awards.

Resonate and New Blue Interactive win Best Use of Analytics and machine Learning in Online Fundraising at annual Reed awards. GlobeNewswire | Resonate Today at 9:20am PDT RESTON, Va., March 17, 2026 (GLOBE NEWSWIRE) - Resonate, the leading provider of predictive consumer intelligence, today announced it has been honored alongside New Blue Interactive (NBI) with the Reed Award for Best Use of Data Analytics/Machine Learning in Online Fundraising. The award recognizes Resonate's approach to applying political intelligence to reach the right audiences with precision messaging and drive exceptional results raising donor money in the political and advocacy space. Resonate revolutionized email fundraising for NBI's client by deploying a custom predictive model for identifying its next-best donors. This solution moved the needle from volume-based outreach to probability-based precision, delivering a 277% lift in targeting accuracy. The initiative expanded the client's email universe by 68.9%, while keeping unsubscribe rates stable, ultimately driving a 64% increase in the average dollars raised per email. "Most donor modeling is just simple look-alikes. It's backward-looking by design. Resonate's predictive modeling is forward-looking at its core with data that told us who was ready to give next, based on what people believe and care about right now," said Taryn Rosenkranz, CEO & President, New Blue Interactive. "This depth of identifying and connecting to donors expanded our email universe, increased revenue, and produced the best fundraising results of the cycle. After more than 20 years in digital fundraising, this is the first time I've seen a model become the competitive advantage." "These honors reflect our commitment to giving advocacy and political leaders the precision they need to cut through the noise with meaningful impact," said Bryan Gernert, CEO of Resonate. "Our work with New Blue Interactive exemplifies the value we place on deep client collaboration and success.
