Episode notes
MSP Market Size And Treeline's Hybrid Vision
- The MSP market is huge but misunderstood, spanning IT, security, and compliance for SMBs.
- Peter Doyle says Treeline aims to combine modern software, automation, and AI with human technicians to reinvent that service model.
Why Pure SaaS Fails In MSPs
- SaaS proliferation hasn't solved messy operational realities inside MSPs that run 30–35 point tools.
- Doyle found selling a 36th tool wouldn't fix half-configured systems, so Treeline started as a services company to rebuild workflows.
Do Question Legacy Processes Before Selling Software
- Don't assume customers will configure new software correctly; change management is the real barrier.
- Doyle advises analyzing legacy processes, asking why they exist, and not expecting instant adoption just because you ship a tool.
