The agency's services include SEO, content marketing, business consulting, and digital strategy. Areas of expertise cover AI content creation, AI digital services, B2B SEO, generative engine optimization, AI market research, managed AI services, AI HR, AI web design, project management, and management accounting. 1Lab focuses on assets that influence AI understanding and comparison, such as decision-stage pages, service pages, pricing pages, FAQs, case studies, entity signals, structured proof, citation coverage, authority building, and AI search monitoring.

1Lab serves clients in the Education, eCommerce, and Corporate Services industries. The agency works with startups, small businesses, medium businesses, and enterprise/corporate clients. It is best suited for B2B SaaS companies, expert service firms, training organizations, and complex offers where buyers compare several options before booking a call.

The agency was founded by Kevin Sauvaget, who leads the team in helping companies improve how they are understood, cited, and recommended across AI answer engines. 1Lab's client roster includes Ravineo, Edreamen, and Veridian. The agency maintains a LinkedIn presence and a YouTube channel.

1Lab's approach is described as precise, anti-hype, and business-oriented. The goal is not only to generate traffic but to help brands become clearer, more credible, and more likely to enter the shortlist when buyers use AI systems to compare solutions. Unlike traditional SEO agencies that add an AI layer afterward, 1Lab was built specifically for the shift from search engines to answer engines.
