How to Build a $10K/mo One-Man SaaS in 90 Days

90-Day $10K SaaS Roadmap

Solo founders are hitting $10K MRR with lean SaaS builds using no-code tools and AI in 2025, proving one person can scale without teams or VC. This step-by-step guide breaks down the exact roadmap, tools, and tactics from real success stories like AutoShorts.ai ($113K MRR) and supastarter ($10K MRR). Optimized for “build SaaS solo 2025,” “one man $10K MRR,” and “no code SaaS ideas,” follow this to launch, validate, and monetize in 90 days.

Days 1-7: Idea Validation and Niche Selection

Pinpoint a painful problem in a niche you know, like marketers needing AI video shorts or devs seeking starter kits—avoid broad markets. Conduct 20 user interviews via Reddit, Twitter DMs, or LinkedIn: “What’s your biggest workflow frustration?” Use Typeform for surveys targeting 30% activation intent.

  • Validate with a one-page landing page on Carrd ($19/yr) promising your solution; aim for 1% trial signups via Indie Hackers/Reddit posts.
  • Top 2025 micro-SaaS ideas: AI content repurposers, privacy analytics (e.g., Seline.so at $600 MRR in 6 months), or no-code CRM automators.
  • Success metric: 50 visitors, 5 pre-signups—pivot if under 10% interest.

Real example: Eric Smith’s AutoShorts.ai targeted video creation pain, validating via marketer forums before coding.

Days 8-30: Build MVP with No-Code Stack

Ship a laser-focused MVP solving one core problem using no-code for speed—no devs needed. Core stack: Bubble.io or Webflow for frontend, Supabase/Xano for backend/database, Stripe for payments, Zapier for automations.

  • Build workflow: Day 8-15 core feature (e.g., AI prompt → video export); integrate Stripe for tiers.
  • Test internally: Aim for 80% user completion rate on key action.
  • Deploy on Vercel/Netlify for $0-20/mo with auto-scaling.

Solo devs like Jonathan Wilke built supastarter’s kit in weeks, hitting $10K MRR via community feedback.

Days 31-60: Launch, Acquire First 10 Customers

Launch lean on Product Hunt, Indie Hackers, and niche subreddits (e.g., r/SaaS)—record a 45s demo video with Flowjam. DM 100 prospects personally: “Saw your tweet on X pain—try my free trial?” Close manually via Zoom, no ads yet.

  • Pricing: Tiered model—Free ($0), Starter ($19/mo), Pro ($49/mo), Enterprise ($99/mo)—annual discounts cut churn 10%.
  • Growth hacks: Build in public (Twitter threads), referral incentives (1 mo free), beta discounts for testimonials.
  • Metrics dashboard: Track CAC (<$50), LTV (>3x CAC), activation (>30%) with Baremetrics/PostHog.

One founder hit paying customer in 24hrs via targeted Reddit launch; aim for $1K MRR by day 60.

Days 61-90: Optimize to $10K MRR

Automate onboarding/support with Zapier + AI chatbots; outsource content (Upwork, $10/hr) to free 10+ hrs/week. A/B test pricing/emails for 20% conversion uplift; engage community for organic shares.

  • Retention: Personalized AI emails, feedback loops—target <5% churn.
  • Scale tactics: Partnerships (e.g., Slack integrations), SEO content (“best AI tool for Y”), upsell via in-app prompts.
  • Weekly review: MRR growth >20%; if stalled, iterate top feature from user data.

Examples: Solo founder crossed $10K MRR solo via niche focus; Eric Smith automated to $113K.

Essential Tools and Costs Under $200/Mo

Run lean: Total stack ~$150/mo scaling to enterprise. Add Plausible for analytics ($9/mo), Sentry for errors (free tier).

Common Pitfalls and Fixes

Avoid scope creep—stick to 1 workflow; perfectionism kills launches. Burnout? Time-block (4 hrs build, 2 hrs sales); join Indie Hackers for support. No traffic? Niche forums over broad ads.
