What Extend Studio does

Extend Studio is a privately held Romanian software company founded in 2005 that builds WordPress products targeting freelancers, bloggers, entrepreneurs, and small businesses. Originally a developer of extensions for Adobe Flash and Adobe Dreamweaver, the company migrated fully to the WordPress ecosystem and now focuses exclusively on five branded product lines: Colibri (a site builder that re-imagines the WordPress Customizer), Kubio (a Block Editor enhancement tool for pixel-perfect responsive sites), Espresso (an onboarding plugin with a setup wizard for hosting clients and beginners), Extend Themes (drag-and-drop WordPress themes), and One Page Express (a single-page WordPress theme).

The underlying technology is conventional WordPress web stack — PHP, JavaScript, ReactJS, VueJS, MySQL, HTML/CSS — packaged into plugins and themes that operate inside WordPress native surfaces (Customizer and Block Editor) to deliver no-code site-building UX. The company runs a self-serve, product-led growth model distributing products through its own websites (colibriwp.com, kubiobuilder.com, espressowp.com, extendthemes.com, onepageexpress.com) and the WordPress.org repository, with reported reach of approximately 200,000 powered websites.

Revenue mechanics are not publicly disclosed but are described as recurring, driven by WordPress themes and plugins sales and a SaaS-style WordPress design platform layer via Colibri. The team is small — about 12 people — headquartered in Bucharest with a secondary office in Brasov, led by CEO and co-founder Horea and CTO Adrian. The company has received an EU research and development funding grant and shows no external venture capital or institutional investor footprint.
