AI Tool Profile
Subgrow
Subgrow opens and runs your own subreddit, writing one Reddit post a day that answers what your buyers search for, so Google and AI search can cite you.
Description of Subgrow
Subgrow is a done-for-you Reddit marketing service for software companies. You give it your website; it looks at your site and your three closest competitors, finds the questions your buyers type into Google, and writes one post a day in your own subreddit to answer them. It opens the subreddit for you if you do not have one, and posts from your brand's own Reddit account, which it sets up and runs as the moderator.
The goal is for Google to show those threads and for AI search such as Gemini, ChatGPT and Perplexity to quote them. The website says it works best for developer tools, AI software and self-serve B2B SaaS, and cites customer results such as AppFollow's subreddit becoming a top source in Gemini answers within three weeks. Pricing is one plan at $99 a month after a 7-day free trial.
Features of Subgrow
- Keyword research done for you: it finds the Google searches your buyers make, starting with your strongest topics, and adds new questions every month.
- 30 posts a month in your own subreddit, as how-to guides, comparisons, top-10 lists or questions, each ready a week early so you can read, edit or skip it.
- Your blog comes too: your 25 newest articles go into the subreddit first and new ones follow, and visits from the posts are tracked in Google Analytics.
Frequently asked questions
How much does Subgrow cost?
There is one plan at $99 a month with everything included: no setup fee, no add-ons and no per-seat charges. It starts with a 7-day free trial, and Stripe emails you 3 days before the first charge. You can cancel during the trial and never be charged.
Do I need my own subreddit or Reddit account?
No. Subgrow suggests a subreddit name from your website and opens it for you, with your brand's own Reddit account as the moderator, which it sets up and runs. You never give it a password, and you do not have to post anything on Reddit yourself.
Can Reddit remove Subgrow posts?
Yes. Reddit's spam filter can remove a post, even in your own subreddit. Subgrow says it never buys upvotes or fake comments, because Reddit bans that and it would put your subreddit at risk.
