Your product isn't the problem.
Your distribution is.
Turn 10 users into 1,000 with referrals that actually work.
No ads. No cold outreach. Just your users.
Each user brings more users. That's the power of referrals.
You shipped. Now what?
You spent 3 months building. Launched on Product Hunt. Posted in 12 Slack communities. Tweeted daily for 2 weeks.
Result? 10 signups. Maybe 15.
The distribution grind hits different:
"Poor sales rather than bad product is the most common cause of failure."
The math is brutal:
Average SaaS CAC increase in 8 years
Spent to acquire $1 revenue (most companies)
Startups die from premature scaling on paid ads
You can't outspend. You need to out-distribute.
Here's what works:
Your users are your best marketers.
Referrals aren't cute. They're THE acquisition channel that compounds:
faster conversion
longer retention
cheaper than ads
It's not linear. It's exponential.
That's how you go from 10 to 1,000 without spending a dollar.

Hey, it's the founder.
I built my first SaaS in 2023. Took 4 months. Launched on Product Hunt. Got 47 upvotes.
Then... 8 signups. Total.
I spent $2,400 on Google Ads over 3 months. Got 23 users. Burned through 40% of my runway.
That's when I realized: I couldn't outspend competitors. I needed my users to bring more users.
So I built Select. A referral system that actually works. No percentage fees. No complicated setup. Just simple referral tracking that turns every user into a marketer.
I used it to grow Select itself. Zero ad spend. 500 users in 12 weeks.
If you're stuck at 10-50 users and can't afford ads, this is for you.
Let's grow together.
