We believe that there is a science to building high-growth products.
We often hear people say it’s luck or intuition, but we think it’s more than that. We believe the startup founders and product leaders who have a good intuition are applying principles that everyone can learn. So we’re on a mission to spread the knowledge to innovators and entrepreneurs everywhere.

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.
Continuous Discovery & Delivery
Work in small, cross-functional teams using design thinking, lean startup, and agile software development. Focus on outcomes, not output.
Set the vision. Communicate the values. Then empower autonomous teams with the context and authority to make great decisions quickly.

What Our Clients Say
As a senior product designer who was consulting on a project with H2R, I joined one of Holly's workshops to better understand her methodology. The workshop developed on the knowledge I was exposed to through seeing Holly work and ended up being an absolute career-changer. Through everything I learned about product discovery, I've been able to bring a unique skillset to the teams I've joined since, resulting in higher pay, more responsibility, more consciousness, and an all-around better professional experience.
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.
I was ready to move forward with what I thought was going to be a really stellar product hire. Thankfully, Holly advised me in that decision before I extended an offer to that candidate. She confirmed that I actually needed a product manager with significantly more experience than the candidate who I was considering. Had I moved forward with that hire without Holly's counsel, not only would I have wasted a lot of time and money, but I also would have created a really negative experience for that candidate. Holly saved me and that candidate. Holly will save you.
A few months ago I was lucky enough to sit in on Holly Hester-Reilly's Data Driven Product Decisions workshop, and I just HAVE to spread the word about this! Every company wants to be "customer driven" but it's easier said than done. Holly and her team have created a fool-proof system for building great products and working with stakeholders. I left the workshop energized and full of ideas and new perspectives, which has helped my business grow exponentially. This workshop will pay for itself.
I appreciated the small group dialogue, and the content around influencing stakeholders, which took the course beyond the typical product dev frameworks. Holly’s personal examples affirmed her credibility and added to the course.
I met Holly when I was seeking a product management job. Holly's insights helped me to land a Technical PM position this year. Big thank you to her for being a true product leader!
Holly spoke to the students in my Design of Business class at Parsons School of Design - The New School. The students loved her, in fact a few of them used that word. The exercises and stories really helped them to put some things in perspective and to further bridge the gap between design and business. She really helped to situate our learnings in the real world.
I really enjoyed the Data-Driven Product Decisions workshop - the topic was one I feel like I am faced with more and more these days. I liked the way Holly did the product opportunity assessment, so I walked my team through some of the exercises to apply to a project we're working on now. It helped us to focus our experimentation.
I especially liked how Holly broke the guidelines of her product opportunity assessment process down into digestible chunks for the break out sessions and built them back up together in the discussion with the other workshop attendees. I also liked the format of a case study with her work at Shutterstock as examples. Felt free but not scary!
Data-Driven Product Decisions is the kind of workshop I’d do on my own, even if my company doesn’t sponsor me. The workshop was structured well, dividing us into groups, having us work silently and then collaboratively. We were constantly building on top of the previous work. I found it very useful! I think it would also be beneficial for strategists and product marketing managers.
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.
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.
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.
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.
The impact Holly and H2R had on our company cannot be overstated. I'm trying to use everything Holly taught me - including doing frequent user interviews to get feedback. We did four interviews or so in the last two weeks.
