What makes your product unique?

LaunchDirectories's answer

Because finding the right places to launch your startup shouldn’t be a guessing game.

I built LaunchDirectories.com to make it simple - it’s a curated, searchable list of the best startup directories, complete with real data like domain rating, traffic, and link type. No fluff, just the info you need to get seen and grow.

Because it’s not just a list — it’s a smarter, faster way to find where to launch. Real data, no fluff, always up to date. Built by a founder, for founders.

What's the story behind your product?

LaunchDirectories's answer

I shared a simple spreadsheet of launch directories on Reddit — it blew up and got 400+ upvotes. People wanted more: domain ratings, traffic, dofollow links… so I built LaunchDirectories.com. What started as a list became a full tool to help founders launch smarter and save time.

They care about SEO, backlinks, and getting real traction from day one. Most are solo builders or small teams looking for smart, lean ways to grow.

Which are the primary technologies used for building your product?

LaunchDirectories's answer

We use Next.js for a fast, modern React-based frontend, Supabase for backend and database services, and Tally for handling forms and user submissions smoothly.
