Agency Growth & Transformation Specialist

Nick Constantinou

About

Professional Background: 20+ years scaling creative and digital agencies from £5M to £40M+ revenue. Led AKQA London to £40M with 18% EBITDA, tripled AKQA New York to £10.5M, and engineered turnarounds for Collective and Monstarlab EMEA. Built world-class teams across 5 geographies, delivered 100+ major awards including 12 Cannes Lions. Expert in commercial strategy, new business development, client portfolio growth, and operational excellence for agencies navigating disruption. Specialist Role: I help creative, digital, and production agencies break free from the project treadmill and build sustainable growth engines. I specialise in reducing client concentration, diversifying revenue streams, and installing commercial frameworks that drive profitability without sacrificing quality. Specific Problems I Solve: Agencies trapped on the project treadmill with dangerous client concentration, eroding profitability, threat of in-housing, and no clear path to sustainable growth. The Approach I Use: I don't just audit - I embed. I work alongside leadership teams to install commercial frameworks, diversify revenue, and build cultures focused on both delivery excellence and profitable growth. I've been in the chair, scaled the business, and know what actually works. Results Clients Can Expect: Diversified revenue streams, improved profitability (targeting 15-20% EBITDA), repeatable new business process, stronger client retention, and a commercial framework that scales.

Role

COMMERCIAL GROWTH & GTM STRATEGIST

Nick brings more than 20 years of experience building commercial strategies and go-to-market models for agencies, consultancies, and tech businesses. He has scaled operations from £5M to £40M+ through client portfolio growth, new business wins, and C-level partnerships, with deep expertise in revenue forecasting, deal construction, sales enablement, and building scalable commercial engines. He has also advised startups and mid-sized businesses on growth strategy, product-market fit, and commercial models built to scale. Nick helps professional services firms, consultancies, and post-Series A tech companies break through growth plateaus. He specialises in scalable GTM strategies, diversifying revenue beyond billable hours, and constructing commercial frameworks that drive predictable growth. The problems he solves are familiar ones: firms stuck billing hours, missing a scalable route to market, exposed by client concentration, or unable to translate product-market fit into execution-ready commercial models. His approach favours practical, executable plans over 100-page decks, with clear priorities, accountability, and metrics. Having scaled businesses from both sides, agency and in-house, Nick knows what actually drives sustainable revenue.
