How HP scaled its Workforce Experience Platform with embedded integrations

Challenge

HP's Workforce Experience Platform processes data from billions of devices and apps to resolve employee issues in real time. But connecting all those apps and tools was slow and complex - every new system or vendor meant custom work, delays, and cross-team coordination.

How fastn helps

HP embedded fastn as a centralized integration layer inside the platform - secure, flexible, and reusable. HP now launches app integrations faster with less manual coordination, manages data flows with more visibility and control, and gives every team a standardized way to connect to any customer environment, with a foundation for AI-powered agents that assist admins and customers.

Result

  • •~75% shorter customer onboarding cycle time
  • •~30% increase in team capacity
  • •~85% of integrations reused across teams
  • •Passed internal security and compliance reviews with no rework
  • •Scalable foundation across 50+ apps and tools

From email-only alerts to 14 delivery destinations

Challenge

Perigon's Signals product detects real-time events for customers, but it could only deliver those alerts by email. Customers wanted alerts in the tools their teams already use, and Perigon's lean team couldn't build and maintain a library of integrations on their own.

How fastn helps

fastn took on the integration layer end to end, designing and building a custom SDK embedded directly in Perigon's product. Customers can now route Signals alerts into Slack, Salesforce, HubSpot, Notion, Snowflake, and more, while Perigon's engineers stay focused on the core product.

Result

  • •From 1 channel (email) to 14 live delivery destinations
  • •Alerts route into Slack, Salesforce, HubSpot, Google Sheets, Notion, Snowflake, and more
  • •Integration layer built and maintained by fastn - no build work from Perigon's team
  • •~40% of active customers adopted a non-email destination

Stop building plumbing: how Four13 builds client integrations 60% faster on fastn

Challenge

Every Four13 integration used to be its own small software project: a dedicated backend per client, dozens of endpoints, scheduled jobs and queues to monitor. One B2B client alone ran 54 endpoints and 55 scheduled jobs across its US and Canadian stores. The work was solid, but it didn't compound. Each new client meant more infrastructure to own, and patterns the team had already proven had to be rebuilt by hand.

How fastn helps

Four13 made fastn the execution layer for TranZetta, its integration platform. Connections, scheduling, auth and observability live on fastn, while Four13's engineers own the logic: mapping, validation, sequencing and the edge cases that make an integration actually work in the real world. Shared flows are configured per tenant instead of copied per client.

Result

  • •60%+ faster to build a new client integration than on Four13's previous code-first stack
  • •About five days to take a new SFTP-to-Cin7 supplier feed from scratch to validated
  • •25+ merchants live on 3PL Connect's shared fastn flows, with dozens more onboarding
  • •Every new Four13 client integration is now built on fastn

In their words

“fastn enables us to move faster and smarter. By embedding their infrastructure directly into our platform, we can now offer secure, observable, and extensible integrations at scale, with less effort and more control. It's helping us evolve from reactive support to proactive intelligence.”
HPWorkforce Experience Platform team
“Our customers wanted alerts delivered where they already work, not just through email. With fastn, we were able to add those delivery options without having to build and maintain each integration ourselves, while staying focused on our core product.”
PerigonJoshua Dziabiak
“We used to start every client integration from scratch, then spend the next year keeping its servers, cron jobs and queues alive. With fastn, the plumbing isn't our problem anymore. My team spends its time on the logic that's actually different for each client, and every new integration starts from what we've already built.”
Four13Greg Flint, Founder & CEO
“With fastn, we went from needing a HubSpot integration to having one up and running in less than a day. What could have required weeks of engineering effort turned out to be incredibly simple.”
