What ChangeTower does
ChangeTower is a private Chicago-based software company operating as ChangeTower LLC that provides a cloud-based, AI-assisted website change-monitoring and archiving platform. The product periodically crawls user-specified public-facing web pages, captures visual screenshots, text snapshots, and source code, and alerts users via email, iOS push, Slack, or SMS when monitored criteria (keywords, HTML snippets, visual changes, code edits, or availability status) match detected changes. Specialized monitoring capabilities include partial-page visual monitoring, keyword and code monitoring, Domain Scanner for whole-domain coverage, KW Discovery for keyword scanning across domains, Time Traveler for timestamped historical archives, and AI-Powered Similar Change Detection that groups similar change events for bulk review. The platform is delivered as a web application (app2.changetower.com), an iOS app, and via a Zapier integration exposing the product to 1,500+ downstream applications, with Enterprise SSO (Microsoft Entra ID, Okta, Google Workspace, OneLogin) added in September 2025.
The company runs a hybrid go-to-market combining a freemium self-serve funnel (free tier with 100 credits per month and up to 2 active checks, a 5-day Power User trial) with an enterprise sales motion supported by "Book a Demo" and dedicated U.S.-based support. Revenue derives from tiered subscription plans (Power User, Enterprise) and professional services for setup, configuration, and custom engineering. Target buyers span corporate marketing and strategy teams, compliance officers in regulated industries, IT and security teams, agencies serving multiple clients, recruiters, PR professionals, and individual consumers tracking prices and deals. Founded in 2017 (firmographics also reference 2016) and led by Founder and Executive Chairman Ari Driessen and CTO Sanil Musić, ChangeTower is bootstrapped with no disclosed venture or institutional funding and operates as an independent private LLC.
