B2B 2015: The Rise of Vertical SaaS and Supply Chain Digitization

What Was B2B in 2015?

In 2015, B2B was moving beyond basic cloud storage into deep vertical integration and the digitization of legacy workflows. The market was defined by the consumerization of the enterprise, where buyers demanded the same UX found in consumer apps for complex tasks like industrial procurement and professional accounting.

Why These 7 Startups Found Traction

These startups succeeded by targeting high-friction, low-transparency sectors like global MRO supply chains and manual bookkeeping. They proved that enterprises were finally ready to move core operational data to the cloud in exchange for automated data entry and centralized vendor management, shifting from fragmented spreadsheets to unified platforms.

What Failed and What to Learn From It

Many 2015 startups eventually struggled because they relied on brute-force manual operations masked as automation or became too dependent on single-platform ecosystems. The assumption that incremental efficiency alone would maintain high margins broke as competition commoditized basic SaaS features and platform owners tightened their APIs.

The Relaunch Opportunity in 2026

The 2026 opportunity lies in Agentic Vertical SaaS—replacing the 2015 "human-in-the-loop" model with autonomous agents that handle procurement and accounting end-to-end. A solo builder can now use LLMs to bridge the unstructured data gap that required massive operations teams a decade ago, creating a leaner, higher-margin wedge.
