During my time at Affirm and Etsy, I saw a new kind of operational risk creeping into high-growth companies: vendor chaos. Every new tool or service added speed in the short term—but over time, we lost track of who owned what, which tools were redundant, and when contracts would auto-renew. The vendors powering our business started to feel like a black box.

This isn’t just our story. Modern companies now rely on a vast network of third-party partners—SaaS tools, AI platforms, contractors, agencies, and managed services. Yet most still track these critical relationships with spreadsheets, scattered docs, and crossed fingers. That’s why we started Stackpack: to turn vendor sprawl into strategic advantage.

Today, I’m excited to share that we’ve raised $6.3 million in seed funding, led by Freestyle Capital, with participation from Elefund, Upside Partnership, Nomad Ventures, Layout Ventures, and MSIV Fund. We’re also lucky to be backed by senior operators who helped scale Intuit, Workday, Affirm, Airbnb, Snapdocs and xAI — and who’ve felt this pain firsthand.

Why vendors are the new employees

Most companies think of themselves as people-first. But in reality, they’re becoming vendor-first.

The average company now has 6x more vendors than employees. And that number is only growing, especially as payroll budgets shift toward AI tools and outsourced talent. But unlike employee systems, vendor oversight is fragmented—or worse, nonexistent. If someone leaves, their contracts just float. Renewals get missed. Spend balloons. Compliance risk compounds.

Finance and IT teams are left holding the bag—without the visibility, ownership, or tools to manage this growing web of partnerships.

Automating what used to be manual

Historically, tracking vendor contracts, owners, and renewal dates was a manual, error-prone process. With Stackpack, it’s automated.

Our platform uses AI to extract key terms, flag risks, and—most importantly—act on behalf of our customers. Think of it like an intelligent agent that ensures nothing falls through the cracks. We give finance and IT teams a single source of truth for everything: renewals, owners, shadow IT, compliance gaps, and cost-saving opportunities. No more guessing who owns what or scrambling before quarter close.

In just a few months, we’re already managing 10,500+ vendors and over $510 million in spend across more than 50 companies, including Every Man Jack, Rho, HouseRx, Fexa, and ZeroEyes.

Building the platform for the vendor-first era

This funding will help us expand our core Stack Management platform and roll out our new product, Requests & Approvals, now in beta. Our long-term mission is to help companies connect with the right partners, at the right time, on the right terms. That means visibility, yes—but also smarter discovery, evaluation, and negotiation.

We’re not just building a tool. We’re building the connective tissue between modern companies and the ecosystems that power them.

If that resonates with you—whether you’re a CFO, IT leader, or just someone tired of vendor chaos—we’d love to hear from you.

Thanks to our team, investors, and early customers for believing in this vision. This is just the beginning!

- Sara, Founder & CEO
