Remote-first. Locally rooted.
Genuine local presence
The engineer running Champlin Enterprises lives in Gurnee — not "serves Gurnee," not "has clients in" Gurnee. On-site workshops, architecture reviews, and standing working sessions across Lake County and the North Shore are the default, not a premium add-on.
No agency layers
A Chicago Loop agency layers project managers, account executives, and junior engineers between you and the work. Champlin Enterprises is one senior engineer with 28 years of production experience writing every line. The same person who hears your problem on Tuesday ships the solution on Thursday.
AI-native, not AI-added
Every engagement is built with AI in the architecture from day one — not bolted on after the fact. Document automation, intake processing, customer support intelligence, operations compression. Real production AI, not demo-ware.
Care Plan stack included
Every build ships with the Care Plan infrastructure: Client Portal for visibility, BugHive for error monitoring, CE Support for direct access, and Pulse for SEO and performance tracking. You stay informed without having to ask.
The model
What this actually looks like
Most software projects fail because the architecture was decided by someone three layers removed from the business. Champlin Enterprises removes those layers. One senior engineer talks to your team, writes the code, reviews it in production, and stays accountable for the outcome.
The engagement starts with a free 30-minute AI Opportunity Audit — three concrete places AI quietly pays for itself in your business, a one-page plan emailed within 48 hours, no pitch. Whether the next step is a Sprint, a full build, or a Care Plan, you keep the plan either way.
Sprint engagements start at $10,000. Full builds scale with the problem. Care Plans carry their own public pricing.

Whether you are in Libertyville, Lake Forest, Waukegan, or anywhere across the Chicagoland corridor — start with a 30-minute conversation. On-site is always available.
30-minute call. One-page plan within 48 hours. No pitch deck.
