What is user activation? Six growth teams on how they actually define the aha moment.

Hila Qu spent years leading growth at GitLab and now teaches it at Reforge, and she starts everyone in the same place: define the aha moment before you touch a funnel. The aha moment is the point where a user experiences your product's core value for the first time, the flash where they get why it exists. It is not a signup, a tutorial completed, or a box checked. At GitLab, Hila's team defined it concretely: two users leveraging two distinct features within the first 14 days of signup.

That specificity is the point. A vague aha, the user is engaged, cannot be measured, targeted, or improved. A precise one becomes the north star every onboarding decision serves. Before you optimize a single screen, write down the exact moment your product's value lands, in the plainest words you can, and make sure everyone on the team would recognize it in the data.

Once you can describe the aha moment in words, Hila Qu's next move is to find its measurable proxy with data rather than opinion. The process is concrete. Brainstorm the high-value behaviors a new user could take early on, the actions that plausibly signal they got value. Then run a correlation analysis: which of those early behaviors most strongly predicts long-term retention and conversion? The winner is your candidate activation metric.

Finally, validate it through experimentation, actively pushing users toward that behavior and confirming that reaching it really does lift retention. This is what separates a real activation metric from a vanity one. You are not guessing that created a project matters. You are proving that users who did it in week one stay, and the ones who did not, leave.

Opinion picks the metric that feels important. Data picks the one that predicts the future.

Ben Williams built Snyk's product-led growth engine, and his definition of activation is a lesson in specificity. Snyk defines activation not as a signup or a first scan, but as a team habit: fixing vulnerabilities within 30 days of when they are created. They landed there because that behavior, more than any other, strongly correlates with long-term retention. To find it, the team combined data science, machine learning models, and qualitative research, hunting for the habit moment and the exact setup steps that lead to it.

The lesson for any founder is that activation is a repeated behavior tied to your product's real job, not a one-time event. A user who signs up has done nothing. A user who has built the habit your product exists to create is the one who stays. Define activation as the smallest recurring action that proves the habit has taken hold.

Georgiana Laudi advises SaaS companies on customer-led growth, and her rule for activation metrics is to tie them to the specific product features that deliver the most value, not to generic engagement. For SparkToro, that meant measuring the search functionality coupled with list creation and exporting, the combination of actions that actually get a user to a useful result. Notice it is not logged in or ran one search. It is the cluster of two or three features that together represent the product doing its real job.

Most activation metrics fail because they measure motion instead of value. A user can click around all day without ever reaching the thing that makes your product worth paying for. Laudi's fix is to identify the handful of features that carry your value, and define activation as the user reaching all of them, so the metric can only rise when real value has been delivered.

Lauryn Isford ran growth at Airtable, and her team made a deliberate, contrarian choice: define activation on a long window, not an immediate one. Airtable's activation metric is week-four multi-user active, a user still actively collaborating with others four weeks after signup. They chose a high bar on purpose, prioritizing behaviors that correlate with sustained product value over the flattering, easy-to-hit signals of day one. The temptation is always to measure the first session, because the numbers are bigger and the feedback is faster.

Isford's team resisted it. A metric that celebrates a first-day click tells you nothing about whether the user got real value or ever came back. By setting the bar at week four and requiring multi-user activity, Airtable made its activation number mean something. It can only rise when users are genuinely, durably getting value, which is the only kind of activation worth optimizing.

Defining the metric is half the job. The other half is redesigning onboarding to reach it, and Airtable's numbers show the payoff. By moving away from a reliance on simple tooltips and building a guided onboarding wizard, personalized use-case flows, and ongoing education, Lauryn Isford's team achieved a 20 percent lift in activation. The principle underneath is that once you know the exact moment a user gets value, onboarding has exactly one job, which is to get them there as fast as possible with as little friction as possible.

Tooltips scattered over a complex interface do not do that. They explain features without leading anyone to value. A guided flow tailored to why this specific user showed up does. Map the shortest path from signup to your activation moment, then build onboarding as that path, and measure it by how many users reach the moment, not how many finish the tour.

Scott Belsky built Behance and led product at Adobe, and he calls the opening stretch of any product the first mile: the onboarding, the orientation, and crucially the defaults a new user lands in. He argues the first mile is critical for retention, and that it gets more important, not less, as a product matures. Early adopters forgive a rough start because they are motivated to figure it out. The more skeptical, mainstream users who arrive later will not.

They stall at the first point of confusion and leave. The defaults matter most because most users never change them, so whatever state you drop someone into is the product they actually experience. The takeaway is to treat the first run as a designed experience, not an afterthought. Audit exactly what a brand-new user sees, does, and decides in their first few minutes, and remove every step between arrival and the moment value lands.

Elena Verna leads growth at Lovable, and she offers the contrarian, forward-looking view: as AI agents get better, the growth team spends less time on traditional activation. The reason is that the core product agents are increasingly designed to bridge the gap to the aha moment themselves, integrating the activation experience into the company's DNA rather than bolting it on as a separate onboarding campaign. In an agent-native product, the user does not have to be walked to value through a wizard. The product does the work and delivers the result.

Verna's point is not that activation stops mattering, it is that where activation lives is shifting, out of the growth team's onboarding flows and into the product's core behavior. For founders building with AI now, the lesson is to ask whether your product can simply produce the aha, rather than teaching the user how to reach it. The best onboarding is the one you did not need.
