What Nelio Software does
Nelio Software is a privately held, bootstrapped software company founded in 2013 in Barcelona, Spain, that develops a portfolio of WordPress-native SaaS plugins. Its flagship product is Nelio A/B Testing, which provides conversion rate optimization capabilities including A/B and multivariate testing, heatmaps, and AI-assisted experiment generation. The portfolio is complemented by Nelio Content (an editorial calendar and social media scheduling tool used by 5,000+ active subscribers), Nelio Session Recordings, Nelio Popups, Nelio Forms, and utility plugins (Translate, Maps, Compare Images). The company holds WordPress VIP Technology Partner status and distributes through the WordPress.org plugin repository, where it has accumulated over 1,000 reviews.
The underlying technology is built around native WordPress and WooCommerce integration, leveraging the WordPress REST API and JavaScript-based rendering for client-side experiment execution. Nelio A/B Testing 8.5 (released July 2026) introduced Nelio AI for test generation and AI-powered homepage analysis, while Nelio Content 4.3 (March 2026) and 4.2 (January 2026) added webhook support, third-party integrations, and link shortener capabilities. The team consists of three co-founders, all PhDs from the Universitat Politècnica de Catalunya (UPC), and the company has not taken any external investment.
Nelio operates a subscription SaaS business model with tiered pricing: Nelio A/B Testing ranges from a free tier up to $449/month, while Nelio Content is priced from $16 to $49/month. The go-to-market is primarily self-serve via WordPress.org discovery and direct subscriptions, augmented by the WordPress VIP partnership for enterprise-tier access. The company reported 24% year-over-year revenue growth in 2025 (exceeding its 20% internal target) alongside 10% subscriber base growth, reflecting durable demand delivered by a three-person, fully self-funded team.
