Zendo is a white-label client portal where agencies and service businesses manage the entire client relationship — from the first intake form to the final invoice — under their own brand.
Most client portals do one or two things well. Zendo handles the full workflow: intake → communication → delivery → billing, with everything connected so nothing falls between the cracks. The platform also supports selling services — productized packages, subscriptions, and custom quotes — though not every customer uses this.
Service businesses that work directly with clients and deliver work in projects or ongoing retainers. Three main segments based on real usage data:
Team size ranges from solo freelancers to agencies with 50+ staff. What they share: they deliver a service, manage it through a client-facing workflow, and need one place for all of it.
Kuba Gaj co-founded WP Kraken — a WordPress agency in Katowice — as part of Massive Pixel Creation. By 2016 the team was handling hundreds of client requests per month across email threads, spreadsheets, and disconnected billing tools.
Nobody knew where anything was. Clients asked the same questions twice. Invoicing alone took hours a week. So the team built their own internal platform — and it changed everything.

Clients started asking to use the same system. Due to technical limitations, sharing it wasn't possible — so the team rebuilt it from the ground up. That became Zendo. MVP launched September 2021.
After analyzing how paying customers use the platform, one pattern was clear: most people buy Zendo as a client portal — for onboarding, communication, file delivery, and billing — regardless of whether they use the sales features. This shaped how we describe the product.
Simple tools that reduce cognitive load are harder to build — but far more valuable to use. Software should disappear into the workflow.
Functionality comes first. But a clean interface your clients enjoy using is part of the product, not decoration.
No consultants. No onboarding workshops. If you can run a service business, you should be up in Zendo the same day.
Technology should reduce the mental load of running a business. When a client pays, you know. When work needs attention, you see it.
