Who We Are

A Different Kind of Consulting Firm

Permenenttsb Consulting Group was founded on a simple premise: strategy is only valuable when it translates into results. Since 2009, we have helped mid-market and enterprise organizations navigate complex business challenges — from market entry and digital transformation to operational restructuring and M&A integration.

Unlike traditional firms that deliver a report and walk away, our engagement model embeds senior consultants alongside your leadership team to co-develop and execute strategies that deliver quantifiable impact. Every recommendation we make is grounded in rigorous data analysis, deep industry knowledge, and practical implementation experience.

Our team of 87 consultants brings expertise from McKinsey, Bain, BCG, Deloitte, and industry-leading companies across technology, healthcare, financial services, and manufacturing. We combine that institutional knowledge with the agility and accountability of a founder-led firm.
