Coaching, consulting, and workshops for executives and product leaders

Scale Like You've Done It Before

Whether you're getting ready to launch that next product or concerned with your growth rate and keeping investors happy, we've got you covered.

Growth-Stage Startups are Challenging

You’ve worked hard to get your company to the stage it’s at today. You've found your first product-market fit and begun to scale.

But more and more, it seems as if the list of things to do keeps growing, meanwhile product development is slowing.

We will help you get or build the skills you need on your team, now.

  • Your investors are telling you it's time to hire more product talent, whether its a CPO, VP, or a Head of Product

  • You have trusted team members whose jobs have grown faster than they have

  • You've got adoption but growth is slowing

  • That major initiative is pre-launch and it's taking too long to build

  • Everyone’s trying to move fast, but they’re not always headed in the same direction

The Product Science Principles

Over 15+ years in tech companies, founder Holly Hester-Reilly has developed product science, a theory for building high-growth products, teams, and companies.

People have more choices today than ever before, so product science focuses on creating experiences they want to be a part of. Our world changes fast, so product science relies on continuous feedback and rapid learning loops.

At its core, product science is about finding people’s pains and developing effective solutions for their problems – with the products we build, the processes we use, and the organizations we create.

Evidence-Based Product Strategy

Understand your users, your market, the product, and feasibility. Make informed decisions about which growth opportunities to pursue.

What Startups Say About Us

When I was being coached by Holly, I was recently promoted to "SVP of Product: Games" at Arkadium. It was a new position and Arkadium hadn't had a history and process of Product Management. Holly brought specific and actionable experience as well as great tools that I could use to start supporting our growing product team and processes. I was able to instantiate player interview tools and habits that significantly improved the quality of our releases.

Tom Rassweiler
SVP Games and Product

I worked with Holly on bringing a large enterprise web product to market, and the job could not have been completed without Holly's leadership as the product owner. Holly is the rare product leader who is the complete package: empathetic to users, effective and fun for designers and engineers to work with, and trusted by executives to deliver on strategic KPIs and maintain transparency from concept to launch. I give Holly my most enthusiastic recommendation.

Dillon Zhang Forrest
Founder and CEO

Working with Holly gave me a better frame of reference. Both from conversations with her that are validating to experiences I’ve had and then also references she's provided — books, articles, some tools. Just a generally bigger toolkit.

Product Management Director

Data driven, execution oriented, leader, go getter. Those are the words I would use to describe Holly. Holly came in to Shutterstock when we desperately needed business direction for Skillfeed (a Shutterstock company). She conducted one of the best data driven business analyses I have seen. Holly collected a tremendous amount of data by surveying the competitive landscape, comparing various industry pricing models, categorizing thousands of user feedbacks and came up with concrete suggestions that are backed by data. Furthermore, Holly was able to be Product Owners on multiple successful teams. I would recommend Holly without reservation.

Holly worked with FalconX at a time of high growth for the product team and as the company was doubling in size. Holly helped us take on many scaling challenges, and her focus on collaboration, communication, and product research left a positive mark on the team.
