Our History

Our Story.

Why SJS Impact was founded — to meet a gap between high-level strategy firms and hands-on operational leadership.

Mission

Carla Stockton-Jones

Partner – Strategy & Transformation

Am an experienced Managing Director and COO who specialises in transforming complex, multi-site organisations and accelerating value creation for FTSE 250 and private equity–backed businesses.

Over the last 20+ years, I’ve led P&Ls of more than £1.4B, turned around underperforming operations, integrated acquisitions, delivered multi-million-pound revenue growth, and built high-performing cultures at pace. My background spans transport, energy, telecoms, field operations, infrastructure and consumer services — with a strong reputation for operational rigour, commercial mindset and transparent, people-first leadership.

I co-lead SJS Impact Consulting, a boutique transformation and interim leadership practice focused on FTSE350 and PE-backed organisations. We help CEOs, investors and boards achieve rapid, measurable improvement — combining strategic clarity with hands-on delivery.

If your organisation or portfolio company requires transformation, turnaround support, or interim executive leadership (MD/COO/Transformation Director), I’d be happy to connect.

Janine

Partner – Strategy & Transformation

I am a commercially focused Managing Director and senior transformation leader specialising in operational turnaround, customer experience uplift and commercial growth in complex national organisations.

Over the last two decades, I’ve led multi-region and multi-discipline businesses across energy services, housing, transport, telecoms and consumer sectors — consistently delivering performance recovery, revenue growth and cultural renewal in fast-moving or highly regulated environments. My experience spans portfolios from £90M to £500M, with full P&L accountability and leadership of workforce populations exceeding 8,000 people.

Alongside my business partner, I co-lead SJS Impact Consulting, supporting FTSE 350 and PE-backed organisations to accelerate impact and deliver measurable improvements. We combine board-level experience with pragmatic, hands-on execution — the kind of transformation that changes numbers, systems and behaviours.
