Who is Ambibma?

Their strategic focus on proprietary format support and advanced typography suggests a commitment to power users who manage their own digital libraries rather than relying on mainstream bookstore ecosystems. The primary tension in their portfolio is the transition from legacy 2-series applications to the newer X-series, which appears to be their current vehicle for modernizing the user experience.
