About the position:

Definitive Healthcare is building a market-leading digital audience business that enables healthcare brands, agencies, and platforms to activate high-quality HCP and consumer (DTC) audiences across the AdTech ecosystem. We are hiring a Platform Partnerships Director to own our platform partner relationships and grow the revenue that flows through them.

This role is the bridge between our data and the platforms where it is activated. You will manage and grow relationships with DSPs, SSPs, data marketplaces, curation platforms, and identity providers - keeping our audiences live and performing, signing the right new partners, and collaborating on healthcare solutions (curated deals, packaged offerings, co-developed products) that differentiate Definitive Healthcare in market. You will also be the market's voice back into Product: what partners are asking for, which audiences are being used, and where demand is growing.

Reporting into the AVP, Digital Sales, this is a highly cross-functional role working with Product, Data Science, Data Engineering, Sales, Operations, and external AdTech platform partners.

Own the day-to-day relationship with existing platform partners (e.g. LiveRamp, DSPs, marketplaces, social platforms), maintaining consistent contact and serving as their commercial point of contact.

Identify, evaluate, negotiate, and sign new distribution partners, prioritizing those that expand reach into the audiences buyers actually want.

Resolve partner-facing issues with audience delivery, match rates, and distribution.

Stay current on privacy, regulatory, and platform compliance requirements - healthcare data considerations, platform policies, NAI/DAA frameworks - and advise teams on what is commercially viable.

Integration with Product & Engineering

Oversee the integration process end to end for each partner, from technical specs through to audiences live and performing in market.

Represent commercial and business requirements as Product, Data Engineering, and Operations define onboarding, mapping, and maintenance of audiences across platforms.

Advise on naming conventions and platform mappings so audiences are positioned clearly for buyers.

Revenue & Commercial Performance

Own revenue performance by partner: track what each channel earns, flag underperformance, and act on it.

Drive revenue growth through partner education - training partner seller teams on our audiences, use cases, and differentiation.

Build the positioning, enablement materials, and go-to-market messaging partners need to sell our data, working with marketing and sales.

Monitor partner commercial health and contract terms, escalating risks and surfacing expansion opportunities early.

Market Intelligence into Product
