| Threat Group | thegentlemen |
| Summary | auren.es zoominfo.com/c/auren/1115886722 AUREN (founded 1998, Madrid) is Spain's leading home-grown multidisciplinary professional-services firm — audit, legal/tax advisory, consulting and corporate finance — with €104 million revenue in Spain and 1,100+ staff in 15 offices (2,500+ people and 62 offices worldwide). Founded and chaired by Mario Alonso Ayala, it sells an integrated "Big Four-style" service portfolio to mid-market companies with a "humanist, close-to-client" culture, plus standout niches in forensic/expert-witness work, public-sector audit and M&A. In March 2025, Dutch private equity fund Waterland took a 49% stake — the first PE investment in a Spanish professional-services firm — giving it firepower for acquisitions. Revenue is split roughly Legal €42M, Consulting €35M, Audit €24M, Corporate Finance €3.4M, and the firm is now on a buy-and-build spree (15–18 deals planned for 2026, its largest being the absorption of Moore España's Madrid and Barcelona offices). |
