Welcome to HarpoonRock.

Our clients are entrepreneurs.

They are leaders in all sizes and types of organizations.

We support them to pursue transformative opportunities and drive bold visions.

Entrepreneurship is the pursuit of opportunity beyond the resources you control for economic, social and environmental impact.*

We believe that entrepreneurs are best positioned to address the challenges from unprecedented global change.

This is founded on our experience working with impact and venture funds, cleantech firms, social enterprises, foundations, non-profits, government agencies and large corporations.

Our practice brings expertise and resources together to help entrepreneurs succeed in a reality of high uncertainty, limited capital and rapid change.

*with thanks and apologies to Prof. Howard Stevenson, Harvard Business School for this adaptation of his classic definition.
