How would you measure the success of Curve's "Go Back in Time" feature?

Introduction

Measuring the success of Curve's "Go Back in Time" feature requires a comprehensive approach to product success metrics. This innovative functionality allows users to switch payments between cards after a transaction has occurred, providing flexibility and potential financial benefits. To effectively evaluate its performance, I'll follow a structured framework covering core metrics, supporting indicators, and risk factors while considering all key stakeholders.

Step 1

Product Context

Curve's "Go Back in Time" feature is a unique offering in the fintech space, allowing users to retroactively change the payment card used for a transaction up to 14 days after it occurred. This feature is part of Curve's broader strategy to simplify personal finance management and provide users with greater control over their spending.

Key stakeholders include:

1. Users: Seeking flexibility and optimal use of their various payment cards
2. Curve: Aiming to increase user engagement and differentiate from competitors
3. Partner banks: Interested in transaction volume and user loyalty
4. Merchants: Concerned about potential chargebacks or disputes

User flow:

1. User makes a purchase using their Curve card
2. Within 14 days, user decides to change the payment source
3. User selects the transaction in the Curve app and chooses "Go Back in Time"
4. User selects the new payment card and confirms the change
5. Curve processes the change, refunding the original card and charging the new one

This feature sets Curve apart from traditional card issuers and other fintech companies. While some competitors offer similar functionalities (e.g., Monzo's "Undo" feature for splitting transactions), Curve's offering is more comprehensive and flexible.

Product Lifecycle Stage: Growth - The feature has been launched and is gaining traction, but there's still significant room for user adoption and refinement based on user feedback and usage patterns.
