How it’s graded

Each check is built on how world-class product and growth leaders do this work, as they’ve described it on Lenny’s Podcast, and names the leader it comes from.

  1. Activation defined by what predicts retention

    Does the review define (or question) the activation event by whether it predicts retention, and judge fixes by their effect on that event rather than on step completion?

    Passes when Names the activation behaviour and its link to retention (from the supplied data, or as an explicit assumption to verify), and ranks fixes by their effect on it.

  2. Gets people to value sooner

    Do the recommended fixes shorten the path to the first moment of value, by removing or deferring steps before it or starting people with templates or sample data, rather than adding tours, tooltips or extra steps?

    Passes when The main fixes cut or defer steps before first value, or give a warm start, and say which steps go.

The brief

You're the PM for onboarding at Tidepool. Omar, our Head of Product, has asked for a review of onboarding (his note is below). Write it in no more than 800 words: what activation should mean for us, the evidence, what to change in onboarding, and what to make of the design team's proposal and next quarter's goal. The files are attached.

What a strong answer doesThe answer key the graders mark against

Works out retention for each first-week behaviour from the file: all sign-ups 28% (1,120 of 4,000); completed the checklist about 30% (barely better than average); connected a bank about 48%; categorised 10+ transactions about 65%; connected a bank and categorised 10+ about 78%, and that group is about three-quarters of everyone retained (842 of 1,120). So the checklist isn't activation and raising its completion to 75% would do little; activation should be connecting a bank and categorising ten transactions in week one. Recommends cutting or deferring checklist steps that sit before that (theme, notifications, savings goal) and getting people to connect a bank and categorise sooner (for example suggested categories to confirm), and resets the goal to the new activation rate (about 27% today, 1,080 of 4,000). Treats the celebration screen and progress bar as polishing the wrong step. Notes that the data shows correlation and proposes a test to confirm that driving the behaviour improves retention.

Executive Summary

Our current activation rate (61%) is flat because we are measuring and optimizing the wrong milestone. Completing our setup checklist barely moves the needle on long-term retention.

To drive retention, we must redefine activation around core product value—connecting a bank and categorising transactions—and reorient our onboarding funnel and quarterly goals to support it.

---

1. What Activation Should Mean (and the Evidence)

Activation should represent the “Aha!” moment: the point where a user experiences Tidepool’s core value proposition and forms a lasting habit.

Currently, we define activation as completing the setup checklist (name account, pick theme, set savings goal, enable notifications). The data shows this is a vanity metric:

  • Baseline Day 60 Retention: 28.0% (1,120 / 4,000 sign-ups)
  • Checklist Completion: 30.4% Day 60 retention (742 / 2,438) — a negligible +2.4 percentage point lift over baseline.

By contrast, actions tied to our core utility (seeing where money goes) dramatically predict retention: * Connected a bank account: 48.2% Day 60 retention (964 / 2,000) * Categorised 10+ transactions: 64.6% Day 60 retention (891 / 1,380) * Connected bank AND categorised 10+ transactions: 78.0% Day 60 retention (842 / 1,080)

Users who complete both core actions retain at nearly triple the baseline rate. In fact, this group accounts for 75.2% of all retained users at Day 60 (842 of 1,120), despite representing only 27% of initial sign-ups.

New Activation Metric: > A user connects a bank account and categorises at least 10 transactions within their first 7 days.

---

2. Design Proposal & Next Quarter’s Goal

#### The Design Proposal (Celebration Screen & Progress Bar) The design team’s proposal is solving the wrong problem. Adding progress bars and celebration screens to cosmetic tasks (picking themes, naming accounts) creates artificial friction before users experience any real value. We are gamifying administrative overhead instead of utility.

Recommendation: Repurpose the design team’s work, but attach it to the real value milestone (e.g., celebrating when their first 10 transactions are imported and categorized).

#### Next Quarter’s Goal (Raise Checklist Completion from 61% to 75%) We should retire this goal immediately.

Even if we hit 75% checklist completion, model projections indicate Day 60 retention would increase by less than 1%. Optimizing an arbitrary checklist delivers zero business impact.

Proposed New Goal for Next Quarter: > Increase the core Activation Rate (Bank Connected + 10 Categorised Transactions) from 27% to 40% of sign-ups.

---

3. What to Change in Onboarding

Our onboarding funnel currently bleeds users before they experience core value: 50% drop off before connecting a bank, and only 34% categorize 10 transactions. We must clear the runway to value:

1. Eliminate the Cosmetic Checklist from First-Run Flow * Move “pick a theme” and “name your account” to Settings/Profile. * Defer “enable notifications” and “set a savings goal” until after the user sees their financial data.

2. Lead with Bank Connection * Prompt bank linking immediately post-registration. * Pre-frame the security and the payoff clearly: “Connect your account to see your last 30 days of spending instantly.”

3. Accelerate Time-to-Value (TTV) on Categorisation * Upon successful bank connection, immediately import transactions and guide the user through a rapid, swipeable 10-transaction categorisation flow (or auto-categorise and prompt a one-tap review). * Conclude with an instant visual breakdown: “Here’s where your money went this month.” This is Tidepool’s true “Aha!” moment.

4. Contextual Budgeting * Only prompt users to create a budget after categorisation. Budgeting retention is low in week one (33.3%) because users cannot budget accurately without understanding their baseline spend.

Next Steps

  1. Align leadership on the new Activation definition.
  2. Re-scope the design sprint from checklist gamification to a streamlined "Connect & Review 10 Transactions" flow.
  3. Update the team OKR dashboard for next quarter.

Output

Onboarding review for Omar

Recommendation

We are measuring setup, not activation. Completing a checklist of preferences does not establish that someone has experienced Tidepool’s value: seeing where their money goes and taking control of it.

Redesign onboarding around that first useful financial insight. Treat the celebration screen and progress bar as supporting elements—not the main fix—and replace next quarter’s checklist-completion goal.

What activation should mean

Use “connected a bank and categorised at least 10 transactions within the first week” as our provisional activation definition.

This combines access to real financial data with an action that helps users understand their spending. It is a stronger approximation of delivered value than naming an account or picking a theme.

The threshold of 10 is a starting hypothesis, not a proven magic number. We should validate whether users actually gain an insight at this point and whether a different threshold or milestone—such as reviewing a spending summary—better predicts durable use. Creating a budget may become a subsequent milestone, but the current evidence does not support making it mandatory for initial activation.

What the evidence says

Among August’s 4,000 sign-ups, overall day-60 retention was 28%.

First-week behaviourUsersDay-60 retention
------:---:
Completed setup checklist2,43830.4%
Connected a bank2,00048.2%
Categorised 10+ transactions1,38064.6%
Connected a bank and categorised 10+1,08078.0%
Created a budget1,23033.3%
Opened the app on 4+ days2,18039.9%

The strongest signal is the combined bank-and-categorisation milestone: 27% of sign-ups reached it, and those users accounted for 842 of our 1,120 retained users. Retention among everyone else was approximately 9.5%.

Checklist completion, by contrast, is associated with retention only slightly above the cohort average. Raising it could improve the reported activation rate without improving users’ outcomes.

These are observational, overlapping groups. Motivated users may both complete meaningful actions and remain active; the data does not prove that pushing everyone through those actions will cause retention. Nor can we infer exact step-by-step drop-off from these aggregates. The CSV also differs slightly from the funnel summary on checklist and categorisation counts; reconcile reporting before setting the baseline.

What to change in onboarding

  1. Lead with the value proposition, then bank connection. Explain what users will get from connecting, how their data is handled, and what happens next. Instrument connection starts, failures, abandonment and successful imports; address reliability and trust barriers.
  1. Replace the upfront preference checklist with a guided first-value journey. Move theme selection and account naming out of the critical path. Ask for notification permission when there is a clear benefit. Keep savings goals optional or introduce them after users understand their finances.
  1. Guide users through real transactions. Provide sensible category suggestions, easy corrections and a short review flow. Then show a useful spending summary—not merely confirmation that ten items were completed.
  1. Offer budgeting as the next step. Help users turn their spending insight into a realistic budget, without making budget creation another prerequisite that delays first value.

Measure the full journey and test changes against the existing experience, including first-week milestone attainment and day-60 retention.

Design proposal and next quarter’s goal

A progress bar is worth testing if it tracks meaningful value steps, not cosmetic setup tasks. A celebration screen belongs after the first useful insight, should be brief, and should not interrupt it. Neither proposal addresses the core problem on its own.

Replace “raise checklist completion from 61% to 75%” with “increase first-week bank-plus-10-transaction activation.” A provisional target of 27% to 35% is reasonable to plan against, subject to baseline reconciliation and experiment sizing—not a forecast supported by this dataset.

Success must also include improved day-60 retention, with bank-connection reliability, privacy complaints and abandonment monitored as guardrails. Keep checklist completion as a diagnostic metric, not the team’s definition of success.
