The Upsert covers the layer between enterprise systems: integration, data movement, and the AI that's reshaping both.Written by someone who builds it.
How tools actually perform under load, not the vendor’s demo.
What broke, why, and how it got fixed, from real implementations.
Data nobody else is collecting, published here first.
What’s changing inside Salesforce, NetSuite, SAP, HubSpot, and Dynamics, and what it means for the people who have to keep them running.
Browse RevOps & PlatformsiPaaS, middleware, EDI, APIs. The build-vs-buy decisions nobody explains honestly, and the ones that actually hold up in production.
Browse IntegrationAgents and AI-driven workflows that are supposed to replace integration work. Most demos lie. We test what reaches production.
Real implementations, told straight. What broke, why it broke, and what it actually took to fix. Not the sanitized case study version.
Original data nobody else is collecting. If a claim about this space can’t be backed by a number, we don’t publish it.
Honest comparisons, field-tested notes, and original research. Once a week.
