How to get your first 100 users for your SaaS

Every successful pre-seed SaaS reached 100 users through founder-led work — cold DMs, one-to-one intros, community participation, and one well-timed launch. Not through ads. Not through SEO. Not through viral loops. The founders who try to skip this step and buy their first 100 users through ads almost always fail, and usually blame the product.

The reason is simple: paid ads, viral loops, and referral programs amplify signal that already exists. On day one, there is no signal to amplify. You have no audience, no domain authority, no reviews, and no conversion data. Every scalable channel assumes you already have momentum. At zero, you have to build momentum manually.

The good news: getting from 0 to 100 is harder than getting from 100 to 1,000. Once you have 100 users, you have social proof, testimonials, and enough data to know which channels scale. The first 100 are the hardest — and the most important.

The fastest path to your first 20–30 users is direct outreach. Not cold email blasts. Not LinkedIn automation. Genuine, personalized conversations with people who have the problem you solve.

Find people publicly complaining about the problem on Twitter, Reddit, and forums. Find people using cobbled-together workarounds (spreadsheets, manual processes, competing tools duct-taped together). Reach out with a genuine offer to help — not a sales pitch.

Target 20 DMs a day for 10 consecutive days before checking reply rates. Most founders quit at day 3 because they've sent 30 messages and gotten two replies. Day-10 cumulative reply rates look completely different. Volume below 20/day is statistical noise.

Find the 3–5 online communities where your target users spend time: subreddits, Slack groups, Discord servers, Indie Hackers, Hacker News. Become genuinely helpful — answer questions, share knowledge, build a reputation. When you launch or add features, you have an audience with trust.

The rule that keeps you from getting banned: be useful first. Spend a week commenting, answering questions, and giving real advice before you ever mention your product. On Reddit and Hacker News, the posts that survive are teardowns, lessons-learned, and honest 'here's what I built and what broke' stories — not launch announcements.

Directory submissions are the highest-ROI activity in your first 90 days. A single listing on a high-DR directory gives you a permanent backlink, referral traffic, and visibility to people actively searching for tools. Multiply this across multiple directories and your domain rating jumps from 0 to 30+ within weeks.

But here's the problem: most directories are broken. Product Hunt gives you 24 hours of visibility and then you're buried. SaaSHub charges $99/mo for featured placement. BetaList charges $1,499 for a 1-week ad. And most directories have a graveyard problem — thousands of dead listings cluttering the directory and burying your product.

That's why we built OnlyFoundrs. Free to submit. $5/mo for everything: instant launch, dofollow backlink, featured placement, newsletter feature, social shoutout, and analytics. Every listing is verified live — no dead links next to yours. Your listing stays live forever, not for 24 hours.

Write publicly about the problems you're solving. LinkedIn posts, Twitter/X threads, or blog posts from the founder's perspective drive more early users than any ad campaign — because authenticity and specificity attract exactly the right people.

This channel is slow — don't expect signups before week 4 — but it's the only one that keeps producing users after you stop working at it. Every good thread or post you write is a permanent asset that can drive traffic for years.

Don't write about your product. Write about the problem. 'How I cut my client reporting time from 4 hours to 20 minutes.' 'Why every CRM I tried failed for solo consultants.' These are the articles that rank for long-tail searches, get shared in niche communities, and keep sending you warm, high-intent visitors.

Here's a realistic timeline for getting your first 100 users. Not a fantasy. Not a growth hack. Just the sequence that works.

OnlyFoundrs is built specifically for the first-100-users problem. Here's how it fits into the playbook:

First, it's a directory where founders and early adopters actively browse for new tools. Your listing gets discovered by people searching for solutions — not just people who already know about you.

Second, for $5/mo you get a dofollow backlink that boosts your domain rating, helping your own website rank in Google. This is the SEO foundation that compounds over months and years.

Third, the $5/mo plan includes a newsletter feature and social shoutout — putting your product in front of our audience without you having to build one from scratch.

Fourth, your listing is permanent. Unlike Product Hunt's 24-hour window, your OnlyFoundrs listing accumulates upvotes and traffic over time. It's the compounding channel that keeps producing users after you stop working at it.
