About Us

“Most business disputes are not simply legal problems. They are situations where value, relationships, and long-term outcomes are at risk.”

— Jonny Lach

Experience That Reflects Real-World Complexity

When founders, owners, investors, or partners enter into conflict, the consequences often extend far beyond the immediate issue:

  • Enterprise value can begin to erode

  • Leadership focus shifts away from growth

  • Relationships fracture

  • Sensitive matters risk becoming public

Jonny Lach founded Dispute Resolute to provide a more thoughtful and effective path to resolve complex disputes before they escalate into more costly and disruptive outcomes.

In addition to his legal background, Jonny brings extensive experience as:

  • Chief Investment Officer

  • Investment consultant

  • Portfolio manager and founder

  • Family office and corporate executive

  • Investment banker

  • Governance and investment committee member

  • Board member

A Different Perspective on Disputes

Having spent his career working with investors, boards, and complex business structures, Jonny understands that disputes are not abstract.

They directly impact:

  • Capital

  • Control

  • Reputation

  • Long-term business outcomes

This perspective allows him to approach mediation not just as a legal process, but as a business-critical decision-making process.
