Stackpack, the first intelligent Vendor Stack Management platform helping companies regain control over their growing network of third-party vendors, has raised $6.3 million. Freestyle Capital led the investment, with additional participation from Elefund, Upside Partnership, Nomad Ventures, Layout Ventures, MSIV Fund and strategic angels from Intuit, Workday, Affirm, Snapdocs and xAI.
Modern businesses are powered by a vast web of third-party providers — AI tools, SaaS platforms, contractors, and managed services. Yet most teams still manage these critical partnerships with spreadsheets, scattered documents, and crossed fingers. Stackpack is changing that.
Founded in 2023 by Sara Wyman, a veteran of Etsy and Affirm, Stackpack emerged from firsthand experience with the chaos and cost of unmanaged vendors. Wyman saw how missed renewals, redundant tools, and growing compliance risks could quietly drain budgets and introduce operational risk — and recognized that the vendors powering a business were as essential to its success as its internal team.
With Stackpack, finance and IT teams get a single source of truth for all third-party vendors – automatically surfacing renewal dates, contract owners, shadow IT, compliance gaps, and savings opportunities. The platform uses AI to not only uncover blind spots, but also acts on behalf of customers as an agent to ensure nothing falls through the cracks. Ultimately, Stackpack turns vendor sprawl into strategic advantage.
The early team behind Stackpack includes early leaders from PayPal, eBay, Adobe, Asana, Twilio, and Google — operators uniquely positioned to build a networked platform and scale it from early stage to market leadership.
Stackpack enters the market at a critical moment: Over $475 billion is spent annually on third-party software and services in the U.S. alone, with an estimated 25% of it going unused. Payroll budgets are shifting to outsourced contractors and AI expense. Compliance risks are multiplying as third-party vendors handle sensitive data. A lack of transparency in renewal dates and pricing are wrecking budgets and forecasts. Today’s finance and IT teams need real-time visibility, automated guardrails, and tighter controls more than ever, and Stackpack is building the platform for this new era.
Just months after launch, Stackpack is already managing over 10,500 vendors and $510 million in spend across more than 50 customers, including Every Man Jack, Rho, Density, HouseRx, Fexa, and ZeroEyes.
Alongside its core Stack Management platform, Stackpack is now expanding beyond visibility with a second product: Requests & Approvals, currently in beta. Designed as a lightweight, affordable alternative to platforms like Zip and Coupa, it gives teams a faster way to evaluate and approve vendor requests. Over time, Stackpack also plans to help customers discover and evaluate new partners.
Looking ahead, Stackpack’s mission is to help companies connect with the right partners, at the right time, on the right terms – transforming vendor management into a strategic capability.
