How to Get Your First 100 Customers

A practical plan for your first 100 customers: pick a narrow audience, sell by hand, use your network and communities, and learn from every early user.

Your first 100 customers almost always come from doing things that don't scale: choosing one narrow group of people, contacting them personally, selling to them one by one, and fixing whatever stops them from buying. Start with your own network and the communities where your audience already gathers, charge early, and treat every customer as a source of the words and channels that will bring the next ones.

The goal of the first 100 isn't growth for its own sake. It's learning who buys, why, and how to reach more of them.

Why the first 100 are different

Later, you'll have channels that bring customers without your personal effort: search, referrals, content, maybe ads. At the start you have none of that. What you do have is time and the ability to talk to people directly, which big companies can't do.

It helps to split the goal into stages:

Step 1: Pick one narrow audience

"Small businesses" is not an audience. "Independent physiotherapy clinics with two to five staff" is. A narrow group:

• shares the same problem, so one message works for all of them;
• gathers in the same places, so you can find them;
• talks to each other, so referrals spread.

Write down who they are, where they spend time online and offline, and what they use today. If you've done customer interviews, you already have most of this. You can widen later; starting wide makes every message weaker.

Step 2: Make the offer concrete

Before outreach, be able to say in one or two sentences what you do, for whom, and what it costs. For example: "A booking page and reminder system for small physio clinics. Set up in a day, founding price of [X] per month for the first year."

Make it easy to say yes:

• A clear price, even if it's a discounted founding price. See how to price a SaaS product.
• A low-risk start: a trial, a money-back promise, or you setting it up for them.
• A page to send people to. It doesn't need to be elaborate; it needs a headline in the customer's words and one call to action. How to write a landing page headline helps with the first line.

Step 3: Start with people you can reach

List everyone who might be a customer or know one: former colleagues, clients, friends in the industry, people who joined your waitlist. Contact them personally — not a mass email.

A simple outreach message:

Hi [name] — I'm building [product] for [audience] because [problem you saw]. You mentioned [relevant thing] a while ago, so I thought of you. Would you be up for a 15-minute call this week? I'd like to show you what it does and hear whether it would help.

Then follow up once, politely, if they don't reply. Most people are busy, not uninterested.

Ask everyone who says no: "Who else do you know who deals with this?" Introductions from a mutual contact get far more replies than cold messages.

Step 4: Go where your audience already is

Communities are the next source once your network runs dry.

• Online communities: subreddits, industry forums, Slack and Discord groups, LinkedIn groups, Facebook groups for specific trades or professions.
• Offline groups: local business associations, trade shows, meetups, professional bodies.
• Newsletters and podcasts your audience follows — some take sponsorships or guest posts.

How to show up without being the spammer:

1. Read the rules. Many communities ban self-promotion outside specific threads.
2. Contribute first: answer questions in your area of expertise.
3. When you do share, describe the problem and what you learned, and mention the product as part of that — not as an ad.
4. Reply to every comment.

Step 5: Do direct outreach to strangers

When warm contacts run out, reach out to people you don't know — by email, LinkedIn or a phone call, depending on the audience. Keep it short and specific:

• Mention something real about them (their business, a post they wrote).
• State the problem you solve in one sentence.
• Ask for something small: a reply, a short call, feedback.

Send a manageable number each day and track results in a simple spreadsheet: who, when, channel, response, next step. Check the rules for commercial email in your country and your customers' countries before sending cold email at any volume.

Step 6: Sell by hand, onboard by hand

For early customers, you are part of the product.

• Set it up for them. Import their data, configure their account, walk them through it on a call.
• Check in after the first week. "Did you use it? What was confusing?"
• Fix what blocks them quickly. An early customer who sees their feedback shipped in days often becomes your best advocate.

This is slow, and that's fine. Hand-holding shows you exactly where the product is confusing, which is what you'll need to fix before you can grow without it.

Step 7: Turn customers into your next customers

Once some people are happy:

• Ask for referrals directly. "Who else do you know who'd find this useful?" works better than a referral button nobody sees.
• Ask for a short review or testimonial — and only publish real ones, with permission.
• Write about what you learned. A short case study or post about the problem attracts people with the same problem.
• Keep a changelog so users see the product is moving.

Step 8: Find the channel that repeats

Somewhere between customer 30 and customer 100, look at your spreadsheet. Where did paying customers come from? Which message got replies? Double down on the one or two channels that work and drop the rest.

Mistakes that slow down the first 100

• Building for months before talking to anyone. Start conversations while you build.
• Targeting everyone. A message for everyone persuades no one.
• Staying free too long. You can't learn willingness to pay without asking for payment.
• Treating sign-ups as customers. Count people who pay or use the product every week.
• Quitting a channel after one try. Most channels need several attempts with a better message before they work — or clearly don't.

A weekly routine

• Contact a set number of new prospects every day.
• Hold a few customer calls each week.
• Ship at least one improvement customers asked for.
• Review your tracking sheet on Friday: what worked, what to drop.

Where Mythex fits

Early customers often need small things fast: a landing page with a sign-up form, an onboarding checklist, a feature a prospect asked for on a call. With Mythex you describe the change in chat and an AI agent builds it into a working web app with a database, which you can publish on a public link. That makes it practical to ship feedback within days. The landing page walkthrough is a good place to start.
