As answered by people managing LaunchDirectories and QuantConnect.
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.
LaunchDirectories's answer
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.
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.
LaunchDirectories's answer
Founders, indie hackers, and marketers who are launching new products and want to get visibility fast — without wasting time on low-quality directories. 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.
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.
LaunchDirectories's answer
We serve a wide range of startups, indie founders, and marketing teams — from solo builders launching their first product to fast-growing startups looking for smart ways to get noticed.
