ISG Case Study: Scaling CRM Across 17+ Manufacturing Companies with HubSpot

Mar 31, 2026 | HubSpot Case Studies

How a Private Equity-Backed Manufacturer Unified Sales, Increased Visibility, and Enabled Revenue Growth


Overview

Industrial Service Group (ISG), a rapidly growing private equity-backed manufacturing platform, partnered with digitalJ2 to implement a scalable HubSpot CRM solution for manufacturing companies.

Facing fragmented systems, inconsistent sales processes, and limited visibility across 17+ acquired businesses, ISG needed a centralized platform to support growth, improve sales performance, and unlock cross-sell opportunities.


Challenge: Scaling CRM Across Multiple Manufacturing Entities

As ISG expanded through acquisition, it encountered common challenges seen in manufacturing CRM implementations, especially within private equity roll-ups:

1. Disconnected Systems Across Acquisitions

  • No standardized CRM across entities
  • Mix of spreadsheets, legacy CRMs, and manual processes
  • No unified reporting or data structure

2. Lack of Sales and Revenue Visibility

Leadership lacked insight into:

  • Sales activity across teams
  • Quote volume and pipeline health
  • Win rates and revenue performance

3. Complex Multi-Entity Data Structure

  • 17+ companies operating independently
  • Some were former competitors, requiring strict data permissions
  • Need for both data separation and shared visibility

4. Inefficient Quote-to-Close Process

  • No visibility into quote turnaround time
  • Misalignment between outside and inside sales teams
  • No tracking of quote approvals or stalled deals

5. Missed Cross-Sell Opportunities

  • Multiple verticals with overlapping customers
  • No structured way to identify or act on upsell/cross-sell opportunities

These challenges are highly representative of digital transformation in the manufacturing industry, particularly for organizations scaling through acquisition.
