Underserved SaaS Consulting-to-Product Studio
Identify a large but underserved enterprise SaaS platform (e.g., Sage 100/300 for construction), build an agency around it, then productize workflows, templates, and plugins into a scalable software business.

Massive enterprise SaaS platforms used in specific industries—like Sage (QuickBooks for construction companies) with tens of thousands of 'how to XYZ in Sage 100' longtail searches—are chronically underserved by specialized consultants and tool-builders. The playbook: (1) start as a consulting agency for that platform's specific industry vertical, (2) identify the recurring workflow problems across 10+ clients, (3) productize those solutions as templates and digital assets at 90%+ margin, (4) build plugins or lightweight SaaS on top of the platform API, (5) potentially sell to the platform or a PE firm.
This mirrors the HubSpot and Salesforce consulting ecosystems but in overlooked niches where competition is minimal. The key insight is that the consulting business funds R&D, validates product-market fit, and builds API expertise faster than any other path. The endgame is either a recurring SaaS product or an acquisition by the platform vendor who wants to show their users get more value.

03 THE VERDICT
This is a capital-efficient, validated playbook used by thousands of successful HubSpot and Salesforce partners, just applied to neglected platforms where competition is thin. The consulting-first model de-risks product development completely. For someone with the right industry background, this is one of the most reliable paths to a $1M+ ARR business with a clear acquisition exit. The main risk is platform obsolescence, mitigated by picking platforms with sticky, slow-moving user bases.
