Porter-Smith joins Inflectiv following the successful exit of his Toronto-based agency, Utopiads.
He has invested personally into Inflectiv as part of this minority partnership, and is an active senior member of his £100 M+ Family Office.
The appointment reflects Inflectiv's focus on disciplined, founder-aligned growth as it continues to build a collaborative network of the top 1% of independent agencies. Inflectiv's model centres on minority equity investment, structured operational support and intelligent shared scale, enabling agencies to accelerate growth while retaining autonomy and control.
Founder and CEO James Rose said:
“As Inflectiv grows, strengthening leadership across the Group is essential. Jack brings first-hand experience of building and exiting an agency, alongside a strong understanding of performance, governance and long-term value creation. His investment and partnership enhance our ability to support ambitious founders with both capital and operational depth, while preserving what makes independent agencies distinctive.”
Porter-Smith will work closely with Group CFO Kevin Steel and agency leadership teams to embed Inflectiv's operating framework across the Group, enhancing performance visibility, financial discipline and strategic alignment. The focus is on equipping agencies with the structure, reporting standards and growth planning tools required to scale sustainably. Rose will continue to lead strategy and M&A activity as Inflectiv expands into new sectors and markets.
The appointment comes at a time when many brands are reassessing legacy holding company structures and increasingly favour specialist independent agencies. Inflectiv's platform combines minority capital, strategic M&A support and structured operational enablement, giving agencies the resources to grow at pace while remaining fully independent.
Inflectiv Group continues to expand selectively, partnering with high-quality independent agencies where there is strong alignment on leadership, ambition and long-term growth potential.
Reflecting on the partnership,
Porter-Smith said:
“What attracted me to Inflectiv was its belief that independence and collective strength can coexist. The minority investment model provides access to capital, shared expertise and operational support, without compromising founder control or culture.”
