About Pet Harmony AI
Pet Harmony AI sells an app that answers pet owners' health questions. Owners describe what they see in their own words. The app, called Harmony, then explains possible causes and suggests a plan to discuss with their veterinarian. Harmony draws on veterinary research and builds a health profile for each pet. The app does not diagnose and is not a replacement for a vet.
Pet Harmony AI is the brand of Harmony AI, Inc., a company in Santa Clara, California. Its app is on the Apple App Store and Google Play, and there is also a web app. The site lists a free plan and two paid plans, at $7.99 and $13.99 a month. Rogdrick Craig is the founder and chief executive officer. In August 2026, the company and SensTek Diagnostics announced a collaboration to explore a platform that pairs early-warning data with rapid on-site tests.

Why Investors Backed Pet Harmony AI
Pet Harmony AI is building an AI health companion for pets. Pet Harmony AI's case is that, unlike traditional AI tools, Harmony "isn't just guessing based on general data." In a joint release with SensTek Diagnostics, it also describes a connected platform meant to flag health changes between vet visits. The company's website does not name its investors.
The problem it targets
The company's pitch starts with owners who look up their pet's symptoms. Harmony builds a health profile for each pet, so its replies fit that animal's history. The joint release with SensTek adds a second goal. Chief executive Rogdrick Craig says the aim is "visibility into health changes long before they would otherwise be recognized."
What the product does
Owners describe what they see in their own words, such as a dog that limps when it goes outside. Harmony then checks veterinary research and replies with possible causes and a plan to bring to the vet. Harmony searches millions of cases, studies and research. The per-pet profile is called the Learning Fingerprint. The app does not diagnose and is not a replacement for a vet. The free plan limits questions. The two paid plans add unlimited questions and voice mode, and only the top plan covers all species.
Progress so far
The app is on the Apple App Store and Google Play, and there is also a web app. Pet Harmony AI offers a free plan and two paid plans, at $7.99 and $13.99 a month. It invites veterinarians to join a network and plans to follow up on content, clinical review and referrals. On August 24, 2026, Pet Harmony AI and SensTek Diagnostics announced a collaboration to explore a platform that links early-warning data to on-site molecular tests. SensTek's release says the companies expect to evaluate it in veterinary clinics, cattle operations and other animal-care settings.
