The situation

Jar is a young consumer fintech product that lets people save in digital gold. The CEO has asked you, the PM for new user growth and activation, to recommend how the next quarter should be spent so the product can grow without depending on heavy paid marketing. Early users understand the idea once it is explained, but many people do not yet have a habit of using an app to save tiny amounts, and repeat behavior is not guaranteed after the first interaction. The team believes the product could appeal to a broad audience, not just experienced investors, but trust, simplicity, and effort are major barriers. Why now: budgets are tight, attention is fragmented, and leadership wants a product-led path that can show clear movement within one quarter. Assume the team can back only one primary go-to-market motion inside the product this quarter, such as onboarding, the first saving experience, repeat-saving triggers, or built-in sharing. Your job is to propose where to focus, why that choice is most likely to create early value for users, and how you would prove it quickly.

What to produce

Write a 1 to 2 page go-to-market strategy memo for the next quarter.

Your answer must

Define the target user segment and the saving job-to-be-done, including why this behavior is hard today.
Recommend one primary product-led growth motion to prioritize this quarter and compare it against at least two plausible alternatives.
Describe the user journey from discovery to first value to second value, and identify the biggest friction or trust points.
Specify 3 to 5 metrics, including one leading indicator, one activation metric, and one repeat-use or retention signal.
Propose an 8 week experiment plan with success criteria, key risks, and what you would do if the test underperforms.

Constraints

Do not change the core product proposition from digital gold savings.
Do not assume a major paid marketing campaign or a large external partnership this quarter.
The plan must be feasible for one quarter and a small cross-functional team.
If you make assumptions, keep them minimal and state them clearly.

Format

Use sections: user and problem, chosen motion, alternatives considered, journey, metrics, experiment plan.
