I lead consumer subscription and mobile products. I pair big bets drawn from user insight with fast experiments drawn from behavioral science, and I measure both against the numbers that run the business.

Approach

How I lead product

A two-pronged strategy

User insights define the few high-priority features worth building to drive real value. At the same time, I use behavioral science to run rapid experiments on smaller things, so the team learns quickly and iterates fast.

Big bets

Built from user insight. One larger feature or improvement per team each quarter.

Fast experiments

Built from behavioral science. Small tests that teach us something every week.

What we learn from the experiments feeds the next big bets, alongside fresh user insight.

Clarity plus ownership

Everyone knows the goals, and we check in on them weekly. Within those goals, product managers have the freedom to build their own roadmaps.

Wins and learnings

No launch is too small to celebrate, and no A/B test is too disappointing to learn something from.

Goal-centric teams

I set a small number of clear metrics that reflect a healthy business, and every team's goals ladder up to them. This is how it worked at Butternut Box.

How the teams worked

Each team paired one larger feature or improvement per quarter with rapid experimentation. Twice a year we ran a deep roadmapping process: interviewing users, pulling together past test results, talking to stakeholders, and working through the top bets for each team's metrics.

Acquisition team

Ran 20+ A/B tests that used behavioral science: better price framing, labor illusion screens, more personalization, and adding and removing steps in the funnel. The goal was to lift the share of users who get through sign-up and subscribe.

Retention team

Launched two major features. One let subscribers reduce their cost in exchange for less value. The other was a new reactivation campaign dashboard with urgency-based UI to bring lapsed users back to renew. Rapid UX and pricing experiments ran alongside both.

From the sign-up funnel

Pick your breedAsking for the dog's breed instead of showing a simple call to action personalized the very first step. It lifted conversion through that step by over 10%.

Fresh facts and discount pillsA fresh fact on each funnel step communicated the value of the product and lifted conversion through the whole funnel by 2%. The discount pills showed users the discount is always applied, which also lifted conversion.

VPN is now among the features users cite most, and is coming to Opera for iOS

The strategy

It rested on user insights and on commercial partnership opportunities for revenue. It doubled revenue from the VPN product inside the browsers in one year and led to the launch of eSIM, a second subscription product.

  • A new team built for the metric. I created a cross-product team focused on moving the key subscription metrics, and empowered them to own how.
  • A weekly rhythm. A weekly check-in on how we were moving the target subscriber numbers, with a report on what we learned from our tests.
  • Rapid experimentation. Fast A/B tests on UX, messaging and pricing.
  • Marketing partnership. Close work with the marketing team to point paid digital marketing at subscription users.
  • Renewal and churn. Tuning the always-on renewal and churn-prevention levers.

VPN Pro

A paid VPN built into the Opera browser. It protects the whole device, not only browser traffic, with no-log servers and a 30-day money-back guarantee.

See VPN Pro

A second feature: eSIM

Launched in Opera for Android on 29 September 2026. People buy a travel data plan inside the browser, with 3GB of free data to try it in selected markets.

I led this launch in the same way as the VPN work: a cross-product team that owned the target metric, a weekly check-in on the numbers, and rapid experiments on UX, messaging and pricing.

Why we built it

My co-founder and I had both been through big career shifts and knew how hard it is to upskill and reframe yourself to stand out in a new field. In the fastest skill shift in history, that has only gotten harder.

I led the interviews and used them to build an MVP. I vibe coded the frontend while my co-founder built the data structure and backend. I then set the roadmap and priorities from what users wanted.

What users told us

They wanted very clear guidance and still wanted room to be flexible. So the coach suggests a roadmap based on deep market intelligence about which skills are in demand, then lets people go back and forth about how they like to learn and with what materials, and adjust the roadmap as their goals and time constraints change.

Every day, users get one achievable learning step in a well-structured roadmap, followed by a moment of delight, so they feel progress and build a habit.

Why frictionless is overrated

In my talk The Psychology of Friction, I took common beliefs about conversion and showed the behavioral science, and the tests, that challenge them. These are the test designs from the deck.

Slide showing an A/B test on sign-up flow length: 24 short-question steps against 5 steps with grouped fields
Myth: fewer steps always winEndowment effectSign-up flow length. Variant A: 24 steps with one quick question per screen. Variant B: 5 steps with several related fields per screen. The more people put in, the more they own the outcome.
Slide comparing a two minute loading screen with going directly to the roadmap in Aurora
Myth: speed is the only metric that mattersLabor illusionAurora roadmap generation. A two-minute loading screen that shows the work being done, against going directly to the roadmap. People value a result more when they believe work was done to get it. I used the same idea at Butternut Box, where it lifted checkout conversion by 5%.
Slide showing an A/B test on role selection: ten generic options against three tailored matches
Myth: users want more control and choiceParadox of choiceRole selection. Variant A: ten generic options. Variant B: three matches tailored to the user's profile. Fewer, personalized options take less mental effort to understand.
Slide showing an A/B/C test on pricing page design: coffee anchoring, decoy effect and plain pricing
Myth: users always choose the lowest priceAnchoring and the decoy effectPricing page, three variants. A: price framed as a daily cost, less than a coffee a day. B: a premium tier priced to make Pro look like the best value. C: plain pricing with no framing. A reference point makes the final price feel like a better deal.

Friction can help

The belief that UI should just get out of the way is also overrated. A deliberate action, like dragging money into a wallet, gives people a moment to take in what they are doing while staying easy and satisfying. I call this positive friction, and I use it alongside moments of delight.

Bringing Circle Sportswear to Oslo

Oslo only had expensive, non-sustainable running brands. So I emailed my favorite running brand, which uses fully sustainable materials and is produced in Europe, and offered to help them launch here.

I worked closely with the run club to learn which items people like, hosted events like pastry runs and bring-a-friend challenges, and used social platforms, including Strava, to spread the word.

Partner

Met the head of Hakone Coffee and set up an initial partnership to test whether selling the gear in a café was viable.

Soft launch

A small selection at the run club. A good portion of the items sold out that day.

Full launch

A full set-up at one of the cafés. Most of the merchandise sold through and we placed a second order.

Expansion

Hakone now sells the brand in all six of its Oslo locations, and I'm in discussions with two premium sports retailers.

Up next

A holiday challenge where members earn stones for coming to run club, bringing a friend, buying gear or coffee, or wearing something festive. The top three stone holders win Circle Sportswear gear a couple of weeks before Christmas.
