Chris Welker

Chris Welker has spent two decades building the systems that sit underneath products people use — the infrastructure, the pipelines, the architecture that makes delivery possible at scale. At LegalZoom he led engineering across a $2B platform, built the API infrastructure serving hundreds of thousands of businesses every year, and used machine learning to automate work that used to require surge staffing and months of delay. At Kaplan he built architecture teams from scratch and secured funding to modernize systems serving over 100,000 students. The technical depth was never the point — it was always in service of getting something to work better for the people depending on it.

He started Plaincheck because of something he kept running into: businesses with real traffic potential sitting on sites that were quietly working against them. Broken structure, missing content, no visibility into what was actually costing them. Agencies would run an audit, hand over a deck, and disappear. The problems would compound. He wanted to build something that stayed — that found the gaps continuously, built the strategy to close them, and delivered the work without requiring the client to become an SEO expert.

To do that, he built the platform himself. The crawler that maps a site and surfaces what's broken. The content pipeline that researches, writes, and delivers optimized content. The observability layer that catches drift before it compounds. It runs quietly behind every Plaincheck engagement — clients see the output, not the machinery. That's the point.

Plaincheck is the managed service built on top of what he built. The model is simple: find what's missing, fix it, keep it fixed.
