Permira has entered Quadrante’s capital structure, a consulting firm that offers engineering, architecture, environment and sustainability services. The deal places Permira alongside Quadrante’s founders and Henko Partners as major shareholders.

Founded in 1998, Quadrante operates on an asset‑light model, delivering white‑collar engineering expertise without heavy infrastructure. With the new investment, the firm plans an accelerated growth strategy, targeting new market segments and scaling its advisory footprint.

Management will retain control, ensuring continuity of Quadrante’s client relationships and operational culture. The partnership with Henko Partners preserves a familiar investment base while injecting fresh capital and strategic guidance.

For investors, the move signals confidence in the niche consulting sector’s resilience and growth potential. Quadrante’s expanded capacity could raise its market share in sustainability consulting, while the backing from a prominent private‑equity firm may spur further deals in the engineering‑services niche.
