Assemble Partners

What Assemble Partners does

Assemble Partners is an independent media services company founded in May 2013 by David B. Heller and Kimberly Bassett in New York City. The firm operates without a proprietary technology platform, deriving its value from senior media expertise, channel relationships, and a productized suite of four offline media offerings — Assemble AUDIO (optimized radio), Assemble MASS (coordinated multi-channel offline media for drive-to-site performance), Assemble PUBLIC (public radio targeting affluent adults 35+), and Assemble MARKET (a disruptive approach to media buying that challenges traditional seller economics). Its clients have historically included Silicon Valley start-ups such as Reputation.com and Pinger, alongside consumer brands seeking affluent audiences and agencies needing white-label media execution.

The business model is a professional services model: Assemble earns fees for media strategy, buying, and execution on behalf of advertisers and agencies, mining the marketplace for cost-efficient inventory and packaging it through its four branded products. Distribution is direct — the firm relies on founder relationships, direct client engagement in the Northeast US, and partnerships with agencies rather than broad marketing campaigns. The company is privately held with no disclosed institutional investors, funding rounds, or parent entity, and operates from a single New York headquarters.

The firm's competitive positioning rests on founder expertise from mcgarrybowen, DentsuNext, Kirshenbaum & Bond, and other agencies, plus established distributor relationships that enable below-market pricing in channels such as public radio. Pricing is quote-based and not publicly disclosed. The company remains small (11–50 employees) with no publicly disclosed revenue, no disclosed AI or technology platform, and no recent strategic signals beyond the 2019 product line launch — leaving its current scale and growth trajectory unclear from available evidence.

Broad incumbents

• PHD Worldwide: Omnicom-owned global media agency focused on strategic media planning and buying. Comparable in service offering to Assemble but operates at vastly larger scale with proprietary planning tools and data partnerships.
• GroupM: WPP-owned media investment arm housing Mindshare, MediaCom, Wavemaker and Essence. Broad incumbent that competes with Assemble for advertiser media budgets across traditional and digital channels; serves as a benchmark for incumbent scale and tool investments.
• MediaCom: GroupM/WPP-owned global media agency with strong performance-marketing orientation. Comparable full-service media planning and buying offering relative to Assemble's offline-heavy bundle approach.
• Mindshare: Global media agency network within GroupM/WPP offering media planning and buying across TV, radio, digital, and emerging channels. Provides direct competitive reference on how scaled media agencies package offline and online media for major brands.
• Initiative: IPG Mediabrands global media agency with cultural and brand-building emphasis. Comparable in service offering across offline and digital channels to Assemble's productized media bundles.
• Wavemaker: GroupM/WPP global media agency formed from the merger of MEC and Maxus. Comparable media planning and buying services across traditional and digital media, serving as another scale benchmark.
• OMD Worldwide: Omnicom's flagship global media agency network. Competes for the same advertiser budgets as Assemble across traditional and digital media channels, with substantially greater scale and international reach.
• Zenith: Publicis-owned global media agency network delivering media planning, buying, and content across traditional and digital platforms. Relevant incumbent comparable for assessing how scale players compete for advertiser budgets.
• Carat: Dentsu's global media agency brand offering media strategy, planning, and buying across offline and digital channels. Comparable service mix with traditional-media-buying heritage similar to Assemble's positioning.

Direct peers
