High performance consultancy with Heather Agan de Visser.

The high-performance consultant dedicated to helping founders, leaders & their teams deliver their mission.

Because meaningful ambitions aren’t achieved by strategy alone. They depend on people who are connected to the mission, confident in their contribution and able to perform through growth, pressure and change. I work alongside ambitious leaders and their teams to create the clarity, connection and momentum that turn important intentions into meaningful progress.

BecauseHigh Performance is Human.


You know where you want to go.

But delivering it has become more complicated.

Do any of these feel familiar?

  • The business is keeping you busy, but its not growing the way you want it to, and you can’t duplicate yourself or create more hours in the day.

  • You are deeply connected to your mission, but often get stuck in the weeds for weeks or months at a time, then surface confused about what to do next.

  • You’re worried about making the ‘wrong’ next move, and feel stuck.

  • The business is growing, but its people and ways of working have not fully caught up with that growth.

  • Your people are busy, but important priorities are not moving quickly enough, and you’re seeing a stop / start cycle.

  • Everything comes back to you - still - decisions repeatedly return to the founder or senior leader.

  • Ownership is uneven and your strongest people are carrying too much all the time.

  • The strategy is clear at the top but becomes diluted or confused across the organisation.

  • Important conversations aren’t happening - they are being lost beneath daily delivery.

Unclear priorities, slow decisions and weak ownership eventually become missed opportunities, lost talent and poorer results.

Disconnection from the mission stops you from delivering it.

The 'high performance is human' philosophy.

Organisations don’t deliver missions. People do.

Strategy sets the direction. Technology creates capability. Process brings structure and consistency. But people make the decisions, have the conversations, solve the problems and take the action that turns them into performance. This becomes even more important as an organisation grows.

A founder or senior leader can no longer hold all the context, make every decision or personally protect every standard. The mission must become shared & held. Ownership must spread. Leadership capability must deepen. People throughout the organisation need the clarity and confidence to act without everything returning to the top.

High Performance is Human is the belief that sustainable growth is created when people have the clarity, connection, authority and trust they need to contribute fully. It creates the conditions for founders to step into the work only they can lead, leadership teams to take genuine ownership and organisations to grow without losing the mission, culture or human qualities that made them successful.

The ‘High Performance is Human’ Transformation Pathway.

Growth changes what an organisation needs from its founder, its leaders and its people. The ‘High Performance is Human’ Transformation Pathway helps organisations see what is restricting performance, strengthen connection to the mission, align people around what matters, distribute ownership and build the capacity to sustain growth.

See clearly.

Connect meaningfully.

Align purposefully.

Own the outcome.

Sustain the momentum. 

Together, these stages move a business from founder or leader-dependent and reactive to clear, connected and collectively capable of delivering what comes next.


Ways to work together

Every mission, leader and organisation is different. The right support depends on where you are now, what you are working towards and what may be getting in the way.

Whether you need a focused intervention, an ongoing organisational partnership or trusted support for the person carrying the mission, together we will shape the work around what meaningful progress requires.

One mission. Three forms of support.

You may already know what you need. You may need a blend of all three. Or you may simply know that the current way of working will not take you where you want to go next. Wherever you see yourself, let’s begin the conversation.

What I make possible for you.

I come into your business as a trusted advisor and working consultant.

I bring the space, perspective, challenge and practical support that are difficult to create from inside the business.

I help you step out of the weeds, see the bigger picture and reconnect with your mission and the work only you can lead.

I help your people reconnect with that mission too: understanding what matters, recognising their contribution and taking greater ownership for bringing it to life.

I create the conversations that need to happen but can be difficult to hold within the everyday rhythm of the business.

There is space for the challenges, frustrations, doubts and mistakes — without losing sight of the ambition or what is possible.

I help you see that your spark is still there. That the mission still matters. And that yes, you can deliver it.

Together, we work out the path back to where you want to be — and forward into what comes next.

I identify the areas that need attention and create bespoke support to address them. I help turn insight into decisions, decisions into action and action into meaningful progress.

The result is greater clarity, stronger connection, better alignment and renewed momentum — with leaders and teams better equipped to continue the work long after I have stepped away.
