Most web shops show you a portfolio. Here's what's behind this one.
Nathan M. Thornhill, Founder & Technology Expert
Nathan Thornhill created CiteStamp, a citation-verification tool that catches references AI made up. Point it at an AI-written bibliography and it checks every entry against the published record, then shows who actually said what, with a receipt. It runs in Overleaf, Word, Zotero, and the browser.
See it at citestamp.com.
He founded ICSAC, the Institute for Complexity Science and Advanced Computing, and built its editorial infrastructure end to end: ORCID-verified submissions, double-blind review, and an open review stack where authors can read the exact rubrics that evaluated their work.
The institute lives at icsacinstitute.org.
The research behind both spans information theory, complexity, artificial intelligence, and the dynamics of consciousness: how information behaves in computer systems, in AI models, and in brains. The newest work sets a brain and an AI model side by side and asks whether the internal motion that carries each to a decision is the same. Most of it comes down to one question: when does a single summary number carry what matters, and when does it quietly throw the answer away.
A scholarly book, Foundations of the Existence Threshold. Seven publications. Four provisional patent applications. A poster at The Science of Consciousness 2026, the world's longest-running consciousness conference, organized by UC San Diego. Presenting a five-minute talk at AIMOS 2026, the Association for Interdisciplinary Meta-Research and Open Science annual conference in Wellington, New Zealand, with the data behind it published openly at Harvard Dataverse.
TechPoint, Indiana's tech industry organization, ran a piece on the research and the San Diego trip in August 2026: Fort Wayne Small Business Owner's AI, Neuroscience Research Heads to UC San Diego Conference.

3Rivers WebTech is where that engineering meets Fort Wayne business. Websites, point-of-sale systems, AI automation, custom software: built with the same discipline that keeps research infrastructure running for months without anyone touching it.
The philosophy transfers too. CiteStamp doesn't rent its infrastructure, and neither should you. Every 3Rivers WebTech build is custom-coded and owned outright: your domain, your code, your hosting account, documented and portable. No platform fees, no subscription treadmill, nothing you can be locked out of.
And there's no layer between you and the engineering. No account manager, no sales rep translating your problem. You talk to the person who builds the thing.
Client work funds the research. The research raises the bar for the client work. Fort Wayne businesses get systems built to a standard most agencies never have a reason to reach.
Nathan was born and raised in Fort Wayne. 3Rivers WebTech exists because the businesses he grew up around deserve better technology than what has been sold to them.
Family-owned businesses. Startups running out of a spare bedroom. Contractors, restaurants, and one-person operations doing real work. The ones that get quoted five figures by an agency, or handed a monthly platform bill that never ends and never actually becomes theirs.
When those businesses grow, Fort Wayne grows. That is the point of the work.
Estimates are free, and the number comes before the work does. No surprise charges, no scope that quietly doubles, no invoice you did not see coming. Project pricing or hourly, whichever actually fits the job. And if the work is not sized for us, you get told that instead of sold something.
No maintenance contract. No software to update. No security patches you have to install. No renewal that bills you whether you used it or not. You pay one time and the thing keeps running for years with nothing from you, not as a promotion, but because that is how it is built.
A site that looks good and does nothing is a failed build. The standard here is whether the phone rings more, quotes go out faster, and the work you hate takes less of your week. Quality is the floor, not the pitch. The job is to leave your business measurably better off than it was.
