Partner Development Manager

Job description

(Senior) Partner Development Manager, Horizontal Platforms, Technology & LLMs New York, Charlotte or Palo Alto hybrid Seize a unique career opportunity. Build and run the hyperscaler, platform, and LLM partnerships that put Intapp at the center of the agentic AI stack for professional firms — designing joint plans with cloud platforms, model providers, and horizontal technology partners that drive measurable impact for clients, partners, and Intapp. Intapp company overview Intapp, Inc. (NASDAQ: INTA) is the governed AI platform for professional firms in highly regulated industries, with more than 2,850 clients and over $600M in annual revenues. Our vertically tailored agentic solutions are built for the specialized workflows, complex relationship networks, and professional compliance requirements of accounting, consulting, investment banking, legal, private capital, and real assets firms. In February 2026 we launched Intapp Celeste, our purpose-built agentic AI platform, alongside expanded collaborations with partners such as Anthropic and Microsoft. By applying Firm AI to firms’ core processes and data, Intapp helps partners, dealmakers, and advisors drive growth, manage compliance, and improve profitability. The Intapp partner ecosystem manifests and completes our vertical AI platform. More than 20 years of focus on professional and financial services has cultivated a growing and unparalleled portfolio of more than 140 data, technology, and services partnerships. Why this role, why now The agentic AI era is reshaping how enterprise software is built, distributed, and trusted. For governed, judgement-heavy industries, the winning vertical AI platform is the one that composes most fluently with the horizontal layer beneath it — frontier models, cloud platforms, identity and security fabrics, and the emerging agent interoperability standards. Intapp Celeste is built to be that platform, and our relationships with horizontal partners are central to making it real. This is a new role built to develop and manage a dedicated partner motion for hyperscalers, LLM providers, and horizontal technology platforms — partners such as Microsoft, Anthropic, and the foundational providers that define how agentic software is engineered, governed, and shipped. These partners extend Intapp's reach into firms' existing IT estates, anchor our governance and safety story, and unlock distribution at the scale of their marketplaces and field organizations. It is a rare opportunity to build at the speed of applied AI — inside a company where the partner ecosystem is a genuine source of competitive advantage — in a market where platform roadmaps, model capabilities, and interoperability standards evolve in weeks, not quarters. What you will do: As (Senior) Partner Development Manager, Horizontal Platforms, Technology & LLMs, you will own and grow a portfolio of Intapp's most strategically important platform, hyperscaler, and LLM partners. You will curate new partners, design and execute partnership plans that deliver growth through co-engineering, co-marketing, co-selling, and marketplace distribution — and help shape Intapp's position in the broader agentic AI stack. The primary initial focus for this role will be running our most strategic partnership with Microsoft, where we have a nine figure commercial agreement and our Cosell motion runs into the tens of millions $ every year. Success requires intellectual curiosity and fluency in our end-markets, our clients' needs, and the combined potential of Intapp and its horizontal partners — then translating that understanding into joint value that reaches clients. The role spans strategy and execution equally, with near-term accountability for pipeline and revenue alongside longer-term ownership of platform positioning. You will report to the Head of Horizontal AI and Platform Partnerships, and work cross-functionally with Product and R&D, Industries, Sales, Marketing, and Services as well as Client Success & Support. The role is highly visible, high-impact, and best suited to an intrapreneurial builder who thrives at the intersection of strategy and execution in a high-velocity environment. Build and execute partner plans (Microsoft focused) aligned to Intapp's growth priorities and the partner program — designing joint value propositions, multi-year collaboration roadmaps, co-engineering agendas, joint go-to-market, and co-selling. Ensure partner plans are embedded in the annual and strategic plans of our business units, R&D teams, and GTM functions. Grow our Microsoft Cosell business globally and also build out our Coinnovation success with them. Translate market and client needs into joint solutions, working with Product, R&D, and Industries teams to identify where deeper integration with horizontal platforms and LLMs makes Intapp solutions, including Celeste, measurably more capable, more governable, and easier to deploy inside our clients' existing IT estates. Drive interoperability and platform motions — embed Intapp into the partner's developer surface, model access layer, identity and security fabric, and emerging agent interoperability standards including MCP and agent-to-agent protocols. Own and grow executive relationships with assigned partners, becoming a trusted advisor and the strategic liaison between them and key stakeholders across Intapp. Drive systematic execution of the partner program across development, co-marketing, co-selling, co-delivery, and co-engineering — and report on progress and results, including partner-sourced, -influenced, and marketplace-transacted revenue, certifications, and joint engineering outcomes. Engage directly in client opportunities and sales cycles where partner involvement strengthens our competitive positioning, completes the solution, or opens access to key stakeholders — including marketplace transactions and platform-led co-sell motions.
