John Powell
Founder & SaaS Entrepreneur, PetCare.Software
SaaS entrepreneur and software engineer specializing in vertical market solutions for pet care facilities. With a First Class Honours degree in Software Engineering and proven experience building, growing, and exiting successful businesses in the pet care industry, John applies systematic software development principles to help kennels, daycares, and catteries automate operations, manage bookings, and scale efficiently.
Professional Background
Founder, PetCare.Software
2024 – Present
Founded PetCare.Software to address the operational challenges faced by pet care facility owners—kennels, dog daycares, catteries, and boarding facilities. The platform provides integrated solutions for booking management, pet profiles, vaccination tracking, feeding schedules, payment processing, and automated communications—helping pet care businesses reduce administrative overhead while improving customer satisfaction and business growth.
Senior Project Manager, UK Research and Innovation (UKRI)
2019 – Present
Manages complex technology initiatives on the Technology and Funding Services (TFS) project, including Python-based Jira reporting systems for EPIC status tracking, cross-functional software development teams, and enterprise-grade project management. Experience delivering production systems for a major UK government research organization informs the robust, scalable architecture underlying PetCare products.
Founder, RevelationPets.com
Successful Exit2015 – 2022
Built RevelationPets.com from scratch in 2015 and grew it into a leading pet care management platform, serving facilities across five countries. Over seven years John handled every aspect of the business—building the booking engine, onboarding customers, refining the product based on real operator feedback, and expanding internationally. He sold the business in 2022. That full journey, from first customer to successful exit, is what makes PetCare.Software different: every feature decision comes from lived experience, not theory.
Key achievements: Built from zero to a multi-country platform — custom booking and scheduling engine, automated customer communications, vaccination tracking, online payments, and a responsive support model that earned hundreds of verified 5-star reviews before the successful exit.
Vertical SaaS Portfolio
2024 – Present
Applying the same proven methodologies from RevelationPets to multiple vertical markets including tattoo studios (MyTattoo.Software), driving schools (MyDriveSchool.Software), and martial arts dojos (MyDojo.Software). This cross-industry experience enables rapid identification of common operational patterns and best practices.
Company Information
PetCare.Software is a trading name of LEAVE.REVIEW LTD, a UK-registered software development company established in 2005.
Why This Matters: LEAVE.REVIEW LTD has been in continuous operation since 2005, originally trading as REVELATION MEDIA LTD—the company that built and operated RevelationPets.com. This 20-year track record demonstrates long-term business stability and genuine operational experience in the pet care software industry.
What RevelationPets Customers Said
During RevelationPets' operation from 2015 to 2022, the platform served hundreds of pet care facilities across multiple countries. These verified Capterra reviews reflect the real-world impact of that work — and the same principles now underpin PetCare.Software:
"We have a small but rapidly expanding facility... to have a supported software package that is constantly updated and kept in the cloud is a true asset to our business. Anyone can use the product with ease... Recently I asked for an enhancement and it was acknowledged quickly, developed and presented back to me within a very short time frame."
"After some frustrating conversations with other companies I chose RevelationPets, and I look forward to using it every day! My clients like it as they find it easy to use."
"Saved time. Allows us to track bookings so we can make business decisions. Allows customers to book online instead of calling us. It is amazing all around and has automated many of our processes that took hours in the past."
"All the data is in one place and is accessible to all my staff wherever they are. The fact that my facility has been able to grow with the software makes it very much a partnership."
"We have been able to decrease the amount of time we need to spend in the office by using the automated features, like reminder emails and online booking."
Why This Matters for Pet Care Facilities: These verified reviews were gathered during RevelationPets' seven years of operation (2015–2022). They demonstrate what pet care facility owners actually need from their software — and the same principles that earned those reviews, automated reminders, online booking, efficient scheduling, vaccination tracking, and responsive development, are built into PetCare.Software from day one.
