The problem

When a founder asks r/SaaS 'what's the cheapest way to do email validation' or 'who has good DMARC reports,' three things happen: the top reply gets the click, the post gets indexed by Google, and the asker quietly signs up for whatever the top reply recommended. If you're not in that thread within 2 hours, you lose.

Manually polling Reddit for these threads is unsustainable. They surface at random hours. Mentionly watches the subreddits 24/7 and pings you when one of your keywords lands in a thread, with the OP karma and the comment count so you can triage.

How Mentionly solves it

Add your category keywords (e.g., 'DMARC parser,' 'email validator,' your competitor names).

We watch r/SaaS, r/Entrepreneur, r/sysadmin, r/cybersecurity, and your other ICP subreddits in real time.

Reply within 2 hours with the helpful answer — usually wins the thread, the click, and the signup.

Frequently asked questions

How fast do you surface a match?

Most matches land in the inbox within 5-10 minutes of posting. Reddit indexes our queries every few minutes.

Will I get reported as spam?

If you write a useful reply that says what you built and why it fits, no. If you copy/paste the same reply, yes. Mentionly is a tool, not a permission slip.
