Our purpose

Leading a team and a business demands different skills than doing the work itself, and today's leaders have to build them while the world around them changes.

Stepping into a bigger role means navigating two kinds of change at once. We partner with high-performing individuals through that transition, when habits are forming and support makes the biggest difference.

Change within

The personal shift: new habits, a new relationship to authority, and leading through others instead of doing the work yourself.

Change around

The shifting system: new teams and stakeholders, reorganizations, evolving markets and technology that reshapes how work gets done.

Portrait of Isabel Canter

Who we are

Isabel Canter

Executive Coach & Founder

Isabel started her career in finance before moving into operating roles in high-growth tech, where change is a constant. She held operating roles at LinkedIn during its $26B acquisition by Microsoft, at Lemonade during its $1.5B IPO, and at a venture-backed company during a $300M debt and equity raise.

Working alongside leaders through rapid growth, uncertainty and major transitions gave her a close view of what it takes to lead well when the ground is moving. She founded C3 Growth Partners after completing graduate-level executive coach training at Columbia University, and now helps leaders across industries lead effectively through change.

FAQ

Common questions

What does a coaching session look like?

Sessions are typically 50 minutes over video, weekly to every other week. They are shaped around where the leader is and what is happening at work, not a fixed curriculum.

How long do engagements run?

1:1 coaching usually runs about six months. Leadership Intensives are shorter and scoped up front, usually 8–12 weeks around a specific transition.

Is coaching confidential? What does the organization see?

Coaching conversations are confidential. For organization-sponsored engagements, reporting boundaries are agreed with the sponsor up front. Sponsors see progress and themes, never the content of sessions.

Do you coach remotely?

Most coaching happens over video, with clients across time zones.

Do you work with organizations as well as individuals?

Yes. Organizations often bring C3 in for newly promoted leaders, a cohort of first-time managers, or a high-potential leader at a critical moment. The coaching approach is the same; the structure is designed around your people and timing.

How do we get started?
