Getting your first 100 SaaS customers before writing code

Executive overview

Most founders build first, then look for customers. That's backwards. Customer acquisition starts before the first line of code — with audience, network, and a landing page that validates demand.

Start marketing before you start building; your launch day revenue depends on it.

Leverage advantages before choosing an idea

• Audit whether you have an audience or a network before picking a space to build in
• An audience helps but isn't required for SaaS — unlike courses or info products, most SaaS buyers don't need to know you
• A network of founder peers is worth building regardless — communities like IndieHackers, MicroConf Connect, or Dynamite Circle
• If you have neither, don't delay: start marketing before coding, not after

Build an email launch list before writing code

• Put up a landing page early — before mockups, before code, before the idea is fully formed
• Capture emails by offering launch updates or a simple opt-in incentive
• Use the list for customer development: send mockups, ask if the product solves a real problem, ask what they'd pay
• A list of 100–500 people lets you validate willingness to pay before any build investment
• Talk about your idea publicly — ideas aren't stolen; execution is what matters

Launch to your list, then scratch and claw

• Two weeks before launch, tease the product to your email list with screenshots or a short demo video
• Offer something exclusive (free onboarding, migration help) — not necessarily a discount
• The list gets you the first 10–50 customers; use them to fix bugs and prioritise features
• After the list, use unscalable tactics to reach 100:
  • Product Hunt launch
  • Hacker News launch post
  • Reddit launch
  • Quora and Stack Exchange answers (one founder reached $35K MRR almost entirely through these)
  • AppSumo deal
  • Podcast tour

Pricing shapes everything

• Underpricing is a common first-time mistake
• 100 customers at $5/month = $500 MRR — not enough to act on
• 100 customers at $100/month = $10K MRR — enough to quit a day job in most places
• Price point determines which marketing channels are affordable — $5/month locks you out of paid ads; $100+/month opens them

Build a marketing flywheel to close the gap

• If the list and unscalable tactics don't get you to 100, pick one pillar B2B SaaS channel and commit for several months:
  • SEO / content
  • Cold outreach
  • Partnerships or integrations
  • Pay-per-click ads
• Experiment — there's no guaranteed path; use founder intuition alongside data

Retention is the harder problem

• Driving 10 new customers/month while churning 10 nets zero growth
• Building a product people don't cancel can take 6–18 months of iteration
• Finding 100 customers is hard; keeping them is harder
