50 SaaS founders, business emails only
01
Say who you want
Plain English. How many, what kind of people, how recent. There are no filters to learn and no form to fill in.
Free. Runs in your browser. Read-only.
People leave their email
on Reddit every day.
Lurk finds the ones you want.
Type who you're after. Lurk reads thousands of public posts, pulls out the addresses people shared on purpose, checks each one and hands you a clean list.
No card, no password. One email, and Lurk's own Reddit access.

Who do you want to reach?
A recording of the real thing. The addresses in it are made up.
Measured on live Reddit, not estimated
215
email addresses from 5 Reddit requests in one test run.
84/100
posts matching "at gmail dot com" hide an address a plain scraper can't read.
$0
per run. A pay-per-result scraper charged about $7 for the same list.
0
repeats. An address you already have is never handed to you twice.
How it works
Three steps. One of them is typing.

Why it finds more
Every default was measured on Reddit first.
Most scrapers scroll a subreddit and hope. We tested what actually surfaces addresses, then built the tool around the answers.
It searches. It doesn't scroll.
Reading the newest 100 posts of a big founder subreddit found 0 emails. Eight searches in that same subreddit found 163. So Lurk searches.
It reads disguised addresses
name at gmail dot com is invisible to a normal scraper. Lurk decodes it, along with the spaced-out and spelled-out versions.
Every address gets a grade
A to F, from a mail-server check, the kind of domain, and whether it's a throwaway or a shared inbox. You pick the floor.
ABCDE
Never the same lead twice
It remembers every address it has given you. Run the same search next month and you only get people you haven't seen.
It knows who's who
Each lead is tagged: founder, freelancer, agency, hiring. About half of raw Reddit results aren't your buyer, and those stay out.
A first line, ready to send
Every row comes with the post title, the thread link and a personalization line you can drop straight into a sequence.
What you get
A list you can actually send to.
Not a dump of usernames. Checked addresses, with the context you need to write a first line that doesn't sound like a template.

Questions
The honest answers.
Is it really free?
The free plan is. One search a day with up to 50 leads, on Lurk's own Reddit access and Claude, no card. Pro is $7.99 a month or $59.99 a year for 10 searches a day and up to 100 leads each.
What do I need to start?
An email address. That's it. You type it once and you're in.
Whose emails are these?
Addresses people typed into public Reddit posts themselves, usually because they want to hear from someone: freelancers looking for work, founders asking for feedback, teams that are hiring. Lurk doesn't guess addresses and it doesn't look anyone up elsewhere.
Does it post or message anyone on Reddit?
No. It reads, and that's all. It never logs into your Reddit account, and it has no code for posting, commenting, voting or sending messages.
Where does my data go?
Your leads live in your browser and your exports download to your computer. The only thing we keep is the email you signed in with.
Is this allowed?
Lurk uses Reddit's official API and only reads public posts. What you do with the list is your responsibility: keep to Reddit's terms and to the email laws where you send, such as CAN-SPAM and GDPR. Write to people about what they posted, and make it easy for them to say no.
