Dilligent explains why moving on from an experiment might cost you

The 'wine effect' and other surprises that reshaped how Box runs e-commerce experiments

Summary In this episode of The Experimentation Edge, host Ashley Stirrup talks with Danielle Oleen, Director of E-commerce at Box, about what it really takes to build a culture of experimentation inside a B2B company. Drawing on 15 years across B2C and B2B at Wayfair, Drizly, Zoom, and now Box, Danielle explains why experimentation belongs to every product team and not just e-commerce, walks through a pricing page saga of one win and two losses that exposed the limits of simplification, and shares the "wine effect" test that won for a reason no one predicted. It's a practical, story rich conversation for product managers, growth leaders, and anyone trying to make better decisions with data. Chapters 00:45 Meet Danielle Oleen and Box's reinvention 02:45 Owning the entire customer life cycle 04:45 Why experimentation matters even without a checkout 07:45 The feature that's used but hidden 11:45 Proving ROI with a scrappy manual test 12:45 Building a culture that shares wins and losses 16:45 The pyramid strategy for prioritizing tests 18:45 The simplification tightrope on the pricing page 24:45 When a test wins for the wrong reason 27:45 Where experimentation at Box goes next Takeaways - Experimentation isn't only for e-commerce. Any product with a funnel, even an AI chatbot, can be measured and improved through testing. - Simplification has a limit. Removing too much can strip away the cues and context buyers actually need to decide. - Share losses as openly as wins. Wins build credibility, and losses build the psychological safety a testing culture runs on. - Prioritize like a pyramid. Fix the widest-impact experiences first, then optimize down into smaller cohorts. - Surprising results are the point. A test can win for a reason you never hypothesized, like the "wine effect," and that's where the real learning lives.

Dilligent explains why moving on from an experiment might cost you

Summary Dan Layfield, Director of Product Management at Diligent, joins host Ashley Stirrup on The Experimentation Edge to trace what fifteen years of A/B testing across Codecademy, Uber Eats, and the Fortune 1000 boardroom actually taught him. He breaks down the Codecademy trial-model rebuild that took four months and several rounds to deliver a 35% conversion lift, why moving on from a losing experiment too early is one of a PM's costliest mistakes, how to escape the B2B feature factory with metrics that genuinely ladder up, why retention should ride a product's natural use case instead of fighting it, and where AI is already replacing weeks of research and analysis. It's a practitioner's guide for product managers, growth leaders, data scientists, and engineers bringing experimentation rigor to both B2C and B2B. Chapters 00:45 Meet Dan Layfield and Diligent 01:45 Two worlds of experimentation, Codecademy and Uber 03:45 The trial model that lifted conversion 35% 06:20 What to do with a losing experiment 08:50 Two flavors of experimentation 09:45 Reading forty metrics at Uber Eats 13:10 Escaping the B2B feature factory 16:45 Anchoring the North Star to real usage 19:15 Where AI fits in research and analysis Takeaways * A losing experiment is often inconclusive, not negative; treat it as a map of the funnel rather than a verdict, and know when a big problem is worth another round. * Persistence paid off at Codecademy: four months and three to four rounds of trial-model testing produced a 35% conversion increase. * Separate your two experimentation modes; high-volume CRO chases many small wins, while big, uncertain bets are worth taking multiple shots to de-risk. * Most B2B product teams are feature factories; the fix is a top-down OKR system, and planning usually breaks in the connections between layers, not inside them. * Anchor retention and engagement to the product's natural use case, and use AI to synthesize research and simple A/B analysis in hours instead of weeks.

The metric Stitch Fix says every experimenter should chase

Summary In this episode of The Experimentation Edge, GrowthBook CMO Ashley Stirrup sits down with Nick Beyler, data science manager at Stitch Fix, where he leads the decision and insights team and owns the company's internal experimentation platform. Nick shares why the metric he most wants is the one he can't measure yet, a North Star that predicts a client's long-term value from their earliest behaviors, and why the most impactful experiment learnings tend to come from adoption friction rather than product bugs. He makes the case that if you're only testing winners you're not taking enough risks, explains how guardrails make that risk safe, and looks ahead to a new in-house platform and the promise of agentic AI. It's a practical, statistician's-eye view of experimentation for product managers, data scientists, and engineers building serious testing programs. Chapters 00:00 Cold open and welcome to the show 01:45 What Stitch Fix actually does 04:15 Balancing AI with the human stylist 05:15 From public policy to the A/B testing adrenaline rush 07:15 Inside the weekly experimentation review group 08:45 The AI style assistant and listening to qualitative feedback 10:45 Why adoption friction beats product bugs 13:45 Testing for losers and building guardrails 15:45 Keep rate, successful fixes, and the holy grail metric 18:15 The new platform and the promise of agentic AI Takeaways * The most impactful experiment learnings usually come from adoption friction, not product bugs. By the time a big feature reaches A/B testing, it's often already a winner, so the open question is how and where to introduce it. * A losing test is a finding, not a failure. If every experiment wins, you're not taking enough risk to learn anything new. * Guardrails and stopping criteria are what make risk-taking safe, especially when the experience is as personal as shopping. * The most valuable North Star metric is the one you can't measure yet, long-term client value, and causal-inference modeling helps predict it from short-term behavior. * Quantitative results are only half the story. Direct, qualitative client feedback inside an experiment often reshapes the rollout more than the numbers do.

What the Expedia Group cannot measure, it cannot ship

Summary Amir Moghaddam, Director of Software Engineering at Expedia Group, joins host Ashley Stirrup on The Experimentation Edge to make the case that measurement is not a reporting step but a gate: what you cannot measure, you cannot ship. Drawing on nearly four years at DoorDash and his current work leading Expedia's air booking platform, Amir explains why he refuses to label experiments winners or losers, how a "failed" pricing test pushed his team toward full personalization, and why a three sided marketplace forces hard trade-offs between competing metrics. The conversation closes on how the same experimentation discipline now applies to shipping and measuring AI. Built for product managers, engineers, data scientists, and growth leaders who care about rigor over opinion. Chapters 00:00 Cold open 00:50 Meet Amir and the air booking platform at Expedia 03:10 DoorDash, growth, and a 70 experiment year 04:20 Three kinds of experimentation at Expedia 06:30 AI velocity and the new frontier model pace 08:30 What you cannot measure, you cannot ship 10:45 The DoorDash carousel and the price experiment 12:45 The three sided marketplace and competing metrics 16:55 There are no losing experiments 20:45 Predictability, LLMs, and Expedia's road ahead Takeaways * "What you cannot measure, you cannot ship" — if you can't measure an outcome, you can't decide whether it's better, so you're just debating opinions. * Measurement spans three live dimensions: spend (more with less), speed (sprints instead of quarters), and quality, with guardrail "do no harm" metrics on top. * There are no losing experiments. A flat result is a signal to either refine the hypothesis or step back and look from a completely different angle. * DoorDash's price experiment proved price by itself doesn't predict orders. Different customers want different things at different times, which pushed the team toward personalization. * A three sided marketplace (buyers, merchants, Dashers) makes metrics compete. Running the test is easy; deciding what to optimize when goals conflict is the real work.

How Fin went from weeks to hours of analysis using AI

Summary In this episode of The Experimentation Edge, host Ashley Stirrup sits down with Raunak Kumar, senior manager of GTM analytics at Fin (formerly Intercom), to unpack how experimentation actually works when the data is messy and the traffic is thin. Drawing on nearly 12 years in marketing analytics across Atlassian, Stripe, and Fin, Raunak explains how AI tools like Claude Code have collapsed analysis from weeks to hours and freed his team to clear its experiment backlog, why declining organic search traffic and a 5x jump in untagged ChatGPT referrals are forcing teams to rethink attribution, and how the most valuable experiments are often the ones that "lose." From a Jira Service Desk bundling test that won on trials but had to be rolled back, to a Stripe contact form that was quietly blocking real buyers, this conversation is a practical guide for product managers, engineers, data scientists, and growth marketers who want to learn more from every test they run. Chapters 0:45 Welcome and what the show is about 1:45 Raunak's role and 12 years in marketing analytics 2:45 How AI and Claude Code changed the analyst's day 4:15 LLMs, declining organic traffic, and the 5x ChatGPT jump 5:15 Two kinds of experiments at Fin: on page and off page 7:15 The Jira Service Desk bundling experiment 10:45 Why the trial winner became a rollback 11:45 Contextual onboarding turns the loser into a winner 14:45 Reading an experiment that loses 18:45 What's next: incrementality, connected TV, and testing creative Takeaways * AI has collapsed marketing analysis from weeks to hours, and the real payoff is a cleared experiment backlog plus analysts who compete on the questions they ask, not the speed they query. * Organic search traffic is declining as ChatGPT, Gemini's AI mode, and Claude answer buyers in place; Fin saw a 5x rise in ChatGPT referrals, but LLMs don't tag that traffic, so attribution has to be proven through experiments. * A guardrail metric saved Atlassian from a costly mistake: bundling Jira Service Desk lifted trials more than 50 percent but tanked activation and paid conversion, forcing a rollback. * A failed test can hold the real winner; contextual onboarding matched to user intent roughly doubled activation and became the default variant after the bundling experiment was rolled back. * In low-volume B2B, read losing experiments for sub-segment signal; a "failed" Stripe form simplification revealed the form was blocking legitimate small-business buyers using Gmail.
