I think the biggest mistake is trying too many channels at once. Getting the first 100 users is probably more about finding where your actual users already hang out and talking to them consistently. For some products that might be Reddit, for others it could just be direct outreach and referrals.

For me, the interesting part is that the first 100 users usually don’t come from some fancy growth strategy. It’s often a few conversations, a couple of referrals, and people genuinely finding the product useful. Once you know why those early users stayed, growth becomes a lot easier to think about.

The interesting part is that the first 100 users often seem to come from one channel that happens to fit the product, rather than a perfect growth strategy. I have seen founders spend a lot of time trying to optimize SEO, paid ads, and social media when a handful of direct conversations with the right potential customers would have taught them much more.

A great product doesn’t help much if the right people never hear about it. What I would be most interested in is which channel produced users who actually stuck around. Getting 100 signups from a launch is very different from getting 30 users who actively use the product and bring others with them. That retention and referral signal seems much more valuable for deciding where to double down.

There really isn’t a one-size-fits-all playbook for those first 100 users. I love how you highlighted that it often depends on timing and unexpected channels. For me, it was definitely an unplanned community interaction that drove the most early sign-ups, not the big SEO push I spent months on. It’s a humbling but exciting process. I’m really looking forward to reading the comments to see what worked for everyone else.

Most founders get their first 100 users from one channel, not five. It usually matches where they already have credibility or where their audience already hangs out. Reddit for dev tools, SEO when search demand exists, referrals when the product spreads naturally. The real unlock is a message that resonates, not the channel itself. Manual, high touch work beats automation early. What space is your product in?

I’ve noticed referrals can be seriously underrated for early SaaS. One happy customer mentioning the product to a few people can do more than weeks of posting content. The hard part is obviously getting that first customer who actually likes the product enough to recommend it.

Honestly, I’d probably focus less on the fastest channel and more on the channel that gives you useful feedback. The first 100 users are still helping you figure out who the product is really for, so getting them through direct conversations can be more valuable than just chasing a big signup number.

The first 100 always seem harder than the next 1,000. You can’t really hide behind ads or a huge brand at that stage. You have to talk to people, show them the product, hear why they don’t want it, and keep adjusting. Not glamorous, but probably one of the best learning stages.

‎I like the Reddit example because community-driven growth can be surprisingly powerful when the product actually solves a problem people are already talking about. You don’t necessarily need to “market” the product aggressively. Sometimes being genuinely useful in the right conversation is enough to get those first few users.

I think the fastest way to get the first 100 SaaS users is to start with a specific audience rather than trying every growth channel at once. Personally, I would focus on solving a real problem for a small group, engaging with them in communities where they already spend time, and using their feedback to improve the product.<div> Referrals and word of mouth can become powerful once users see real value.</div>

I think timing plays a bigger role than people admit. You can have a solid product and still struggle because you’re talking to the wrong audience or showing up at the wrong time. Then one random post, referral, or conversation suddenly brings in more users than everything you tried before.

The funny thing about early SaaS growth is that the channel you spend the most time planning for isn’t always the one that works. Sometimes it’s one customer, one community post, or one random introduction that starts everything. I’d be really interested to hear how many people here got their first 100 in a way they never expected.

‎My takeaway from most founder stories is that the first 100 users are rarely acquired in a predictable way. It’s usually messy. A few from outreach, some from content, someone shares it, then another person refers a friend. I actually think that’s pretty normal for early stage SaaS.

I think the fastest way to get your first 100 SaaS users is to avoid trying to scale too early. Instead of spending heavily on ads, I’d start with direct outreach and communities where the exact target users are already talking about the problem you’re solving.<div><div>The first 10–20 users can come from personal outreach, LinkedIn, X, Reddit, niche communities, or simply reaching out to people who might benefit from the product. At that stage, the goal isn’t just getting signups. It’s having real conversations and understanding why people use the product, what they struggle with, and what almost makes them leave.</div><div>Once you have a few users getting real value, referrals become much easier.
