Quasinfalível is a consulting, auditing and training company specialised in software process quality and business-critical certifications.
Founded in 2010 and based in Lisbon, Portugal, we support organisations in building robust, adaptable and high-performing teams through international standards and modern methodologies. Our key areas of expertise include CMMI, ISO 9001, ISO 27001, ISO 22301, ISO 20000, ISO 42001, NP 4457, and Agile Leadership.
We believe that organisations deliver better value to their clients when they operate with clarity, structure and collaboration. That’s why we work side by side with our clients, not just for them, helping them evolve their practices, systems and people.

Our approach
At Quasinfalível, we combine technical rigour with a human-centred approach.
We work on-site whenever possible to stay close to teams and real challenges.
We engage stakeholders directly, managing resistance and supporting sustainable change.
We rely on a network of trusted partners and subject matter experts, ensuring the right mix of skills and cultural fit for every project.
We also maintain active ties with academia, innovation hubs and professional networks — contributing to project management education, mentoring thesis work, and co-developing MOOCs on Agile Leadership with leading institutions like Técnico Lisboa.
