For AI indie founders

Make the call, on the record — evidence for and against, side by side.

Enter the decision you're weighing, your evidence, and where your product stands. Get back a saved brief that names the decision, separates supporting from opposing evidence, states your confidence and unknowns, and gives you a bounded 7-day test with continue / watch / stop thresholds.

How it works

01

Submit the decision

Product URL, the decision you're weighing, your deadline, up to five evidence links, and your current users, revenue, and channels.

02

Get an inspectable brief

A fixed rubric — not an outside model call — organizes what you gave it: a decision statement, evidence for and against, confidence, and named unknowns.

03

Run the bounded test

A 7-day test with explicit continue, watch, and stop thresholds tied to your own numbers, so the next step is obvious either way.

Evidence — for

2

3 of the last 5 paying users specifically mentioned using it to log daily build progress, unprompted.
https://example.com/evidence/support-thread-1
Two customer calls this week said they'd pay more for a public build-log template.

Evidence — against

1

Exit survey shows 4 churned users wanted general-purpose notes, not a build-log-specific tool.
https://example.com/evidence/churn-survey

Mixed / unclear signal

1

A support thread requests both broader and narrower templates in the same conversation — mixed signal.
https://example.com/evidence/support-thread-2

Confidence — High

Both sides are represented: 2 supporting and 1 opposing item(s).
4 evidence item(s) were reviewed, giving more than a single data point.
Live usage or revenue data is present, grounding this in real traction rather than intent alone.

Unknowns

1 item(s) were marked mixed or unclear and were not counted for either side.
This brief only reflects what you entered — Soloop does not fetch, crawl, or independently verify the linked pages.

7-day test

For 7 days, route new signups or outreach through X / Twitter into the single ICP or workflow you're testing, and measure conversion only within that segment.

Continue / watch / stop thresholds

Continue

6+ distinct users take the test action within 7 days (~15% of your 42 current users). Continue as planned.

Watch

Between 2 and 5 users take the test action. Extend the test one more week before deciding.

Stop

Fewer than 2 user(s) take the test action, or you see explicit negative signal (churn, refund request, or direct "not for me" feedback). Stop or pivot rather than keep building.
