UpYourStack with Railsware's Coupler.io
Every business collects data, but not every business uses it effectively. Messy spreadsheets, disconnected dashboards, and human error can lead to costly mistakes—sometimes in the hundreds of thousands of dollars. That’s exactly what happened to Railsware, a product company that ran into a $150,000 data discrepancy due to a simple Excel formula error. Instead of accepting this as an inevitable part of business, they built Coupler.io—a tool that helps businesses turn scattered data into clean, reliable insights.
 
In this episode of UpYourStack, Noah Berk, Co-CEO of Aptitude 8, sat down with Yaroslav Lazor and Sergiy Korolov, the creators of Coupler.io, to discuss:
  • Why most businesses struggle with data accuracy
  • How Coupler.io eliminates human error in reporting
  • The biggest gaps in HubSpot analytics and how to fix them
  • Why data is useless unless it’s actionable
 

The $150,000 Excel Mistake That Started It All

The idea for Coupler.io was born in the middle of the night when the Railsware team was recalculating revenue for bonuses. They discovered that the revenue in their CRM didn’t match the revenue from their invoices. The culprit? A simple Excel error. Someone had added a row to a spreadsheet but forgot to include it in the sum formula. That one mistake cost them $150,000—a massive amount for a growing company. "This trick alone costs companies around the world trillions of dollars every year," said Yaroslav. They realized there had to be a better way.


What is Coupler.io?

At its core, Coupler.io is a data automation tool that helps businesses pull data from multiple sources—like HubSpot, Google Sheets, and CRMs—and create accurate, real-time reports. Unlike traditional reporting tools, Coupler.io isn’t just about visualizing data—it’s about making it actionable.

Why HubSpot Users Need Coupler.io

HubSpot has built-in reporting, but it has limitations. Many businesses need custom reporting but don’t have the resources to:

  • Clean and structure their data manually
  • Merge multiple data sources into one dashboard
  • Identify trends and correlations across teams
Coupler.io solves these challenges by letting teams:
  • Automate data transfers from HubSpot to other platforms
  • Combine data from different sources, including CRM, sales, marketing, and support
  • Build dashboards that help teams take action

The Real Problem with Dashboards

Most dashboards look impressive, but are they useful? "People love pie charts and bar graphs, but they just scroll through them without knowing what to do next," said Sergiy.

Coupler.io ensures that every dashboard answers one critical question: What action should I take based on this data?

For example, instead of just showing customer churn, Coupler.io’s dashboards show:

  • Which customers are at risk
  • What common pain points they mention in support tickets
  • What proactive steps the team should take to retain them
 

How Data Mistakes Cost Businesses Millions

Many companies think they’re making data-driven decisions, but in reality, they’re running blind.

Sergiy explains: "The majority of businesses—from small startups to enterprises—are completely blind about what’s going on. Wrong decisions are made because the wrong data was in the wrong hands."

Some of the most costly mistakes businesses make with data include:

  • Trusting outdated or incorrect reports
  • Making assumptions instead of analyzing real trends
  • Relying on manual data entry, which is prone to errors

The Future of Data Automation

Looking ahead, Railsware is working to make Coupler.io even smarter. They envision a tool that can:
  • Detect data anomalies automatically
  • Suggest optimizations based on historical trends
  • Auto-update reports in real time
Their goal is to eliminate manual reporting entirely.
 

Final Thoughts

Data is only as valuable as the insights it provides. With Coupler.io, businesses can move beyond messy spreadsheets and create dashboards that drive real decisions. If your business is struggling with messy data, manual reporting, or disconnected systems, it might be time to explore Coupler.io.
