Christopher Miller on How HubSpot Built a PLG Empire on Free Software

Steal What Nobody Else Wants

When Christopher Miller joined HubSpot in 2016, the company had just launched a free CRM. It was a bold move, but nobody knew what to do with it. Self-service revenue was a rounding error.

Miller's tiny growth team saw an opening. They walked up to the team nominally responsible for self-service and asked point-blank: are you working on this? The answer was no. So Miller's team took it.

We approached the team who owned it and we were like, are y'all working on this? And they were like, nah, we're working on a bunch of other stuff. We were like, can we take this? And they were like, sure, if you want it. And so we took it and immediately blew it up.

That attitude of radical ownership—treating every problem as your problem—helped the growth team find opportunities the business wasn't explicitly asking them to solve. When you deliver, people keep feeding you bigger challenges.

Relentless Curiosity Beats Formal Training

Miller's number one trait when hiring growth PMs isn't experience. It's relentless curiosity. He wants people with an insatiable desire to understand things and zero fear of admitting when they don't.

His second trait: resilience. If you're doing product-led growth right, 70 to 80% of your experiments will fail. If you can't handle that, you'll start grasping for small wins that don't move the needle.

If your primary modality of product-led growth work is experiment-driven product development and you're hitting more than 30 to 40% of the time, you're thinking too small.

Miller also looks for coachability and creativity. The best growth PMs are ambivalent to solution complexity. They take zero pleasure in building sophisticated widgets. Simple solutions to hard problems win every time.

Scrape Your Knees Early

Miller's path into product management started when he overheard a founder say they needed a PM. He Googled "what is product management" and asked if he could do it. They said yes.

He spent years scraping his knees through trial and error at a B2B2C fitness app. The real inflection came when Fareed Mosavat hired him and taught him to talk directly to users, analyze data at scale, and articulate hypotheses before building.

It was almost like I didn't realize I was blind until—or you didn't realize you weren't seeing in color. I can actually make informed decisions about what I'm shipping.

— Christopher Miller

His advice for breaking into PM: don't optimize for title or company size. Find someone battle-tested who will invest in you. Ask a PM how you can make their day easier. Do volunteer labor. Shadow. Build advocates who will spend professional capital on you.

Crash the Meeting With a Pricing Pitch

Miller wasn't on the guest list for a HubSpot party at the Guinness Storehouse in Dublin. But he got in. So did his designer, Mariah Moscato.

They ran into the COO. He asked what they thought about pricing and packaging. Miller and Mariah pitched a completely different model—right there, pints in hand. The COO invited them to present at the next executive meeting.

They panicked. They weren't ICs who typically got that kind of access. But they showed up and pitched. HubSpot didn't adopt the full plan, but elements of it made their way into pricing over time. More important: Miller earned a seat at the table.

The lesson isn't about parties. It's about doing the work before anyone asks. Miller had a point of view on pricing because he was relentlessly curious about how all the pieces of the business connected. He spent time on the sales floor. He talked to people in other buildings. He understood context most PMs ignored.

Why You Need Sponsors, Not Just Mentors

Miller credits his career inflection to managers who were more than mentors. They were sponsors and advocates—people willing to bet professional capital on him.

Fareed Mosavat was one. Miller thinks he bombed that interview. But Fareed saw something and invested anyway. That investment—time, coaching, hard feedback—changed everything.

Miller's advice: put ego aside. Embrace not knowing things. Embrace not being good at things. Let the desire to be great overpower the fear of being inadequate. Show up coachable.

The best feedback is hard and ugly. Take it. Say thank you. Extract what makes you better. That's what builds bridges with people who don't owe you anything but choose to invest in you anyway.
