Sightivo is an SEO and AI visibility platform for startups that finds and prioritizes the places where they should get mentioned โ€” built for founders, solopreneurs and small marketing teams. Sightivo recommends the opportunities that matter most, ranked by fit, unlike large SEO suites that just give you long lists of sites that mention your competitors.

Start with just your website and Sightivo maps your market, then gives you four ways to get mentioned: get listed on directories with pre-filled submissions, reach out to authors of listicles you belong in with a pitch drafted from their article, answer live threads where your buyers are asking, and publish content targeting keyword gaps your competitors miss.

Sightivo drafts outreach with full context, and enriches contacts with verified emails, LinkedIn profiles and Twitter handles. It also covers the basics: AI visibility tracking across ChatGPT and Claude, keyword and rank tracking, competitor share of voice, backlinks and citations, directory listings, and an outreach CRM.

Questions & Answers

As answered by people managing HTTP Header Analyzer and Sightivo.

What makes your product unique?

Sightivo's answer:

Sightivo covers both halves of getting found: classic SEO signals and AI answer visibility, tracked against the same set of prompts and keywords. Instead of only reporting where you stand, it finds the specific directories, listicles and communities that shape those answers and hands you the ranked list of places worth pursuing.

Why should a person choose your product over its competitors?

Sightivo's answer:

AI-visibility tools stop at measurement โ€” they tell you which answers mention you and leave the next step to you. Sightivo turns each gap into a concrete opportunity with the page, the contact route and the prepared submission details, so a founder without an agency can act on it the same day.

How would you describe the primary audience of your product?

Sightivo's answer:

Founders, solopreneurs and small marketing teams doing their own SEO and visibility work โ€” bootstrapped startups that can't justify agency fees or enterprise SEO tools but still need to be found in search and in AI answers.

What's the story behind your product?

Sightivo's answer:

It started from understanding how founders build amazing products that people can't find, and wanting to solution around that.
