Unifying Data from 12 Tools into a Single Dashboard

#data #full-stack #case-study

A Series B MarTech startup had a common problem: their data lived in 12 different tools — HubSpot, Salesforce, Stripe, Intercom, and more. Nobody had a single source of truth.

The Problem

Every Monday morning, the leadership team spent 2 hours pulling reports from different tools and trying to reconcile numbers. Marketing said one thing, sales said another, finance had a third version.

The Solution

I built a unified data platform that:

  • Connects to 12 data sources via APIs and webhooks
  • Normalizes and deduplicates data in real-time
  • Powers a single dashboard with AI-generated insights
  • Alerts on anomalies using statistical models

Tech Stack

  • Next.js for the dashboard frontend
  • Node.js for API integrations and data pipelines
  • GCP for infrastructure
  • BigQuery for the data warehouse
  • dbt for data transformations

Results

  • 5 hours/week saved per team member
  • MRR increased by 35% through data-driven decisions
  • Leadership has instant access to unified business metrics
  • Monday morning report meetings eliminated entirely

The takeaway: most companies don’t need a fancy AI solution — they need their existing data connected and accessible in one place.
