Ep 59: Why Your Spreadsheet Is the Most Expensive Tool in Your Tech Stack
You’re probably paying for a dozen software tools, but the most expensive one might be the spreadsheet everyone keeps going back to. In this episode, Jay Feitlinger and Sarah Shepard talk about how messy “Frankenstack” systems waste money, create reporting chaos, and make teams rely on people instead of processes. If your numbers never match and no one fully trusts the data, this conversation will feel very familiar.
Key Takeaways:
* Your spreadsheet isn't free. When you're already paying for tools that could do the job, defaulting to Excel means you're doubling your costs without realizing it.
* Tribal knowledge walks out with your employees. When the one person who built your tech stack leaves, so does every password, integration, and workaround they knew by heart.
* Your data is speaking two different languages. Even tools from the same company, like Google Ads and Google Analytics, can report completely different numbers, and that's costing you the wrong decisions.
* A "good enough" source of truth beats a perfect one you'll never have. Chasing 100% data accuracy is a trap. What you actually need is a reliable enough signal to guide your next move.
* You don't need a new tool. You need a champion and a process. Someone has to own the tech stack, document it, and do a quarterly gut-check before you add another subscription you'll forget about in six months.
