AdCellerant, a digital advertising technology and services company backed by Clearview Capital, retained Lantern Partners to recruit its Chief Financial Officer. Based in Denver, AdCellerant partners with media companies, agencies, and brands to plan, deliver, and scale digital marketing programs through a single unified platform. The company’s proprietary AI-enhanced platform, Ui.Marketing, brings media planning, campaign activation, order management, reporting, and training into a single system. Combined with an expert support team, the platform enables more than 400 media partners and agencies to run omnichannel campaigns efficiently while maintaining real-time visibility into performance. Clearview invested in AdCellerant in late 2023, partnering with the company’s founders and management team to support its next phase of growth.
As AdCellerant continues to expand its platform, partner network, and omnichannel capabilities, the company sought a CFO who could bring financial discipline, operational rigor, and strategic partnership to the CEO, Board, and leadership team. We are pleased to announce the appointment of Jonathan Kalstein as Chief Financial Officer.

Kalstein has held CFO and senior finance leadership roles across multiple technology organizations, including Confience, Zenput, and Convercent. In these roles, he guided finance functions through periods of rapid growth, built the reporting and forecasting infrastructure to support scale, and partnered closely with CEOs and investors on strategy and capital decisions. Earlier in his career, he held senior roles at Deloitte and Agilent Technologies.
At AdCellerant, Kalstein will lead the finance organization and serve as a key partner to CEO and co-founder Brock Berry, the Board, and the broader leadership team. He will guide the company’s financial strategy as it invests in its platform, its partners, and the infrastructure needed to make high-quality digital marketing more accessible. He has built finance functions for exactly this kind of growth, and AdCellerant gains a proven partner for its next chapter as a leader in digital advertising technology and services.
