FAQ
Frequently asked questions
How Startup OG works, and what to know before you list or buy.
About Startup OGWhat is Startup OG?
Startup OG is a directory of software and tools for startups and small teams. Each product has a profile, and where we have enough information we compare it with its closest alternatives. We also publish free tools and founder guides.
How do I find the right software?
Browse by category, search for the job you need done, or open an alternatives page to compare a product you already know with its competitors. Verified listings are confirmed by their owners.
Is it free to list my product?
Yes. You can list for free by adding the Startup OG badge to your website and completing verification. There is also a $19 one-time option that does not require the badge.
What does the verified badge mean?
It means the owner has completed Startup OG’s listing verification. Verified listings can have a dedicated product page. It is not a rating or an endorsement of product quality.
Can I browse products that haven’t been claimed?
Yes. Unclaimed profiles stay in the directory and link to the product’s own website. Dedicated product pages become available after verification.
Are the free tools really free?
Yes. The calculators, generators and utilities in our free toolkit work in your browser without an account.
