About IntelliVen


IntelliVen Senior Operating Partners work with leaders and their teams to get clear about what they seek to accomplish; aligned on their purpose, roles, processes, and metrics; and on track to perform better and grow faster.

We develop, use, and provide best practice tools, methods, and tutorials, based on what we have learned from running and growing dozens of successful organizations, to make doable the hard-to-implement actions driven by disarmingly simple truths about business and organization development.

Impeccable Track Record


  • We work with leaders and their teams as a collective whole.
  • We cultivate independent competence.
  • Our world-class, system of proprietary tools, templates, and tutorials make doable the hard-to-implement actions driven by disarmingly simple truths.
  • Our content and approach are optimized for online or in-room delivery.
  • Our principals are available by the meeting, hour, project, and as part- or full-time CxOs.
  • Everything we do is distinguished by executive competence in organization development and the practical application of human behavior theory.


  • Perform and grow according to a plan.
  • Identify and realize Value Creation Drivers.
  • Determine and implement Strategic Growth Initiatives.
  • Create sustainable growth and enterprise value.
Representative Example Cases


  • Organization, unit, and function leaders who have a mission to achieve, a point to prove, or a mark to make.
  • Entrepreneurs who want to go from PowerPoint to reality and drive to scale.
  • Baby Boomers who own and run a business out of which they want to transition but that are not transition ready
  • Professionally financed teams that want to create maximal value in minimal time.


  • At a growth inflection point.
  • Rolling out a new product or entering a new market.
  • Reorganizing, merging, divesting, or spinning out.
  • Transitioning, expanding, or culling executive team.
  • Preparing for funding or stepping up after a cash infusion or big win.


  • “What do I most need to do next to achieve breakthrough performance?”
  • "How do we launch, drive, and guide Strategic Initiatives to realize our potential to perform and grow."
  • How do I transition operations to the next generation?”
  • How do I avoid giving up or selling below target valuation?”
