Automated Asset Formatting

Directories have strict, varying image requirements. We auto-resize logos, crop screenshots, and generate pixel-perfect banners for ProductHunt, Twitter, and LinkedIn so you don't have to open Figma.

Headless Submission Engine

Our fleet of headless browsers navigates the submission forms for you. We handle the login, the extensive questionnaires, and the captcha solving. You just watch the green checks appear.

Competitor Intelligence

See exactly where they get their traffic.

Don't launch blindly. Our competitor search engine reverse-engineers their exact directory footprint, backlink strategy, and SEO gaps so you can outrank them on day one.

The Old Way

Without SignalScan: You launch with a broken OpenGraph image and then spend 40 hours manually filling out 100 identical forms on directory sites. You forget half of them.

ERROR: 404 Submission Failed

The SignalScan Way

With SignalScan: You know 100% certainly that your tech is flawless. Then our bot does the submission work for you. You focus on the users.
