The first meeting is always free - we love hearing your stories and we're happy to share free ideas you can implement yourself. Real human interaction Fish Percolator is a business run by real people with interests beyond the tech sphere. If you think your other suppliers don't come with enough Twin Peaks or Kate Bush references, maybe it's time to look this way. We're passionate about making a difference and so of course accessibility, diversity and inclusivity are core to everything we do. And we're part of the creative community at Duke Studios so we are friends with dozens of small businesses that can cater to all your creative needs.
