— FROM THE COMMUNITY

Founders who stopped guessing.

★★★★★

I was drowning in Reddit threads and YouTube videos looking for my next idea. SignalIDX is the first thing that actually made me feel like I was doing research, not just browsing.

Marcus T.
Indie hacker, shipped 3 products
IDB-0526
★★★★★

The deep-dive sections are absurdly good. ICP, GTM, moat — it's like having a co-founder who did all the market research before you even had the idea.

Priya S.
Solo founder, B2B SaaS
IDB-0849
★★★★★

Bought lifetime on day 1. The signal data alone is worth it — I stopped guessing which spaces had momentum and started building with actual evidence.

James K.
Developer turned founder
IDB-3395
★★★★★

I filter by TAM > $1B + LOW competition + diff ≤ 3 every Monday morning. It's my weekly ritual for finding what to prototype next.
