Coaching

Build a product leader who doesn't need you for every decision.

We put a senior CPO alongside your product leader for 3 months. Weekly sessions, real challenges, applied on the spot.

Get started

What you walk away with.

A product leader who makes better decisions, faster
A roadmap aligned with business strategy
A team that operates without constant CEO involvement

The problem it solves

When Coaching is the right move

Four situations where this is the right call.

You're a founder running Product yourself.

You're making product decisions without a strong framework. You need a senior sparring partner who's done it before.

Your product leader is solid but needs to level up fast.

Your Head of Product is execution-strong but strategy-weak. They need to move faster on prioritization, org design, and stakeholder management.

You're navigating a critical transition.

Post-Series A, international expansion, pivot. These moments call for stronger product leadership. Coaching accelerates the learning curve.

You need senior judgment without a full-time hire.

Hiring a CPO takes 6 to 12 months. Coaching gives you access to the same level of judgment in 3 months, at a fraction of the cost.

What changes

Coaching takes 3 months. The impact outlasts the program.

In the first month

Clearer prioritization. Confidence in saying no. Better stakeholder communication.

In the first 3 months

Roadmap aligned with business strategy. Team operating with clearer ownership. Faster decisions on product bets.

After the program

Product leadership that doesn't require constant founder involvement. Systems that hold without you.

Get started

What you get

Stellar doesn’t deliver frameworks or decks that collect dust. We work side-by-side with CEOs to fix what actually blocks Product & Engineering.

We identify what needs to change most."

Deep assessment of your current product challenges
Goal-setting for the 3-month program
First sessions focused on your most urgent priorities

We work through the hard problems together.

Weekly 1-on-1 sessions on roadmap, hiring, prioritization, and org design
Async support between sessions for quick questions
Document reviews: roadmaps, OKRs, org charts, job descriptions

We make sure it sticks without us.

Consolidation of new frameworks and decision-making habits
Preparation for full autonomy after the program ends
Final session with a 6-month action plan

What makes it different

Why this works

Most coaching teaches frameworks. Ours changes how decisions get made. Every session is run by a CPO who's been in your position before.

Led by doers, not teachers.

You're not coached by someone who teaches Product. You're coached by a CPO who's led teams through growth, restructurings, and pivots.

Customized to your context, not a fixed curriculum.

We start with your biggest challenges and adapt every week. If priorities shift, the coaching shifts.

Applied learning, not theory.

Every session ends with actions you implement before the next call. You're not learning frameworks, you're making better decisions in real time.

Real customer reviews, no BS.
