Tony Castillo

Tony Castillo founded WISLR.ai, which measures how brands show up in AI search and what that traffic is worth. Fifteen brands run on it today. Before that he spent 20 years in enterprise ecommerce analytics, led a 16-person department at Corra, and built a $5MM strategy practice at The Maze Group.

Tony Castillo is the founder of WISLR.ai and Redirects.net, and has spent 20 years in organic growth and user behavior analytics for enterprise ecommerce.

He built WISLR.ai after conventional analytics stopped explaining where traffic was coming from. AI crawlers do not fire JavaScript tags, so the visits and citations produced by ChatGPT, Perplexity, Google AI Overviews, and Claude were landing in direct or in unknown, and brands were reading a growing channel as a rounding error. WISLR.ai reads server logs instead. It classifies AI referrals, verifies bot traffic against the IP ranges the model vendors publish, and attributes the path from crawl through citation to visit, lead, and revenue. 15 publishing and ecommerce brands run on it today across Adobe Commerce, Shopify, and Salesforce Commerce Cloud. One of them now sees 12 percent of total revenue arrive through the AI channel.

Before starting his own practice, Tony was Director of CRO and SEO at The Maze Group, a Shopify Premier Partner, where he grew the client strategy practice from a standing start to $5MM in three years and led organic and conversion work for GNC.com, Toms.com, and MichaelKors.com. Prior to that he was Director of Optimization at Corra, a Shopify Platinum Partner later acquired by Publicis Sapient. There he recruited and led a 16-person department for five years with 90 percent retention, delivered across 24 concurrent enterprise brands, and launched 40 ecommerce sites on Magento Enterprise and Shopify. The largest of those launched without losing organic traffic or revenue, and averaged 15 percent revenue growth in the 90 days after go-live.

He authored a patent-pending algorithm for redirect mapping that uses NLP and vector search to match old URLs to new ones through a site migration. It is the engine behind Redirects.net.

Tony publishes original research on AI crawler behavior at wislr.com/articles and re-tests his findings as the models change. He speaks on how generative surfaces choose their sources, what makes a brand citable, and how to measure a channel that does not report itself.

He received a Coca-Cola Scholarship in 2000 and has served on its selection committee since 2017, mentoring two to three scholars a year through their first year of college. He holds a Bachelor of Science with Honors from Rochester Institute of Technology, where he studied Information Technology and Design. He lives in Atlanta.
