3 ways to see (and solve) a user acquisition bottleneck

It is time to put theory into practice. The previous post covered AARRR metrics. Today we will look at a hypothetical, but extremely common, case.

The problem

Marketing launches a campaign and visits go up, but the signup rate stays low. We bring three profiles to the table. Spoiler: all three are right.

The technical view

The flow asks for personal data, username, password, confirmation, and email validation. From an engineer’s perspective it is sound: fewer fake accounts, better data quality, and a predictable system. It is not a technical problem.

The Growth view

Only 60 out of every 100 visitors complete email validation. If the requirement is not instant, we are wasting the marketing investment. The form should be shorter and support Social Login.

The Product view

We are asking for a commitment —personal data— without proving value. Users do not leave because the form is difficult; they leave because they do not yet know whether it is worth completing.

The resolution

All three are right. Unless there is an obvious bug, no business problem is that simple. Someone has to give.

Option A: deferred signup

Let users enter the app and create value. Ask for registration only when they save their progress.

• Pros: zero friction and demonstrated value.
• Cons: anonymous sessions, data migration, and intermediate states make implementation complex.

Option B: Magic Links

Make login and signup email-only, with no passwords.

• Pros: minimal friction and easy implementation.
• Cons: we still ask for an email before showing real value.

Conclusion

This case is hypothetical, but it happens every day. Every perspective is valid. Our job is not to pick a winner; it is to find the balance that solves the problem in front of us.
