One Stack, Zero Middleware Dependencies

The Situation

A funded B2B SaaS startup had grown quickly — and so had their tech stack. By the time we engaged, they were running a CRM, a separate email service provider, a customer data platform, and Zapier middleware holding it all together. Custom code patched the gaps that Zapier couldn’t handle.

Every new campaign required a developer. Every data sync had a failure rate. The marketing team was operating in constant firefighting mode.

Which Pillars We Engaged

Technical — stack rationalization and systems integration Analytical — data flow architecture and unified reporting

What We Built

We started with a full audit of every tool in the stack: what it did, what it cost, what it integrated with natively, and whether its function overlapped with another tool.

The diagnosis: three of the five platforms had significant feature overlap. The middleware existed entirely to compensate for tools that weren’t designed to work together.

Our approach:

• Stack rationalization — consolidated five tools into two, with native integration between them
• Eliminated all middleware — direct API connections replaced Zapier and custom code
• Unified data layer — single source of truth for customer data, syncing bidirectionally between CRM and marketing platform
• Reporting rebuild — one dashboard showing the full customer journey, from acquisition to expansion

The Result

The team went from needing developer support for every campaign to running independently. The stack scaled to 3x their subscriber volume without a single integration failure. And the marketing team finally had reporting they could trust.
