How to Start a SaaS Business with No Money: A Step-by-Step Guide
Publié : juin 27, 2025
To start SaaS business with no money, you should rely on your own skills, creativity, and strategic thinking instead of a big bank account. A number of companies started similarly: a strong concept and hard work can be the main gears. Your focus should be to:
- Solve one specific problem with a lean Minimum Viable Product (MVP).
- Compare free-tier tools available for development and marketing.
- Find your first customers through organic outreach and direct community engagement.
This guide breaks the journey down into a practical, step-by-step framework:
Validate Your Idea and Meticulously Define Your Target
Before committing resources, be sure to highly validate your SaaS concept. Your primary task is to identify a specific and well-defined but solvable problem for an identifiable target audience. To begin, ask yourself: “Is this problem urgent and important enough that someone would pay to resolve it?” and “Can I realistically reach and serve this niche with minimal resources?“
Rely heavily on market research. This means analyzing more than just competitors; it means actually speaking to potential users. Methodology:
- Interviews: Conduct 10-15 casual interviews with people in your target niche. Understand their current pain points and how they try to solve them now. Do not pitch your solution at this stage.
- Solution: After determining a core problem, sketch out a possible answer (or a simple landing page) and present it to a different set of 5-10 potential users to test their reaction.
- Landing Page Test: Develop a simple landing page using a free builder (like Carrd, or a template on GitHub Pages). Be sure to articulate the value proposition for your specific niche. Include a call-to-action for an “early access” or “beta interest” signup. Track conversion rates.
Instead of a generic “AI content writer,” a validated idea might be an “AI-powered tool that generates hyper-niche industry jargon for B2B marketing emails in the renewable energy sector.” This is very specific and solves a distinct pain point for a target group.
Nick from Writify AI found success by targeting a niche user group: high school and college students needing an AI essay writer.
Try to solve one tiny problem exceptionally well for your initial MVP. This reduces scope and makes validation easier. Many successful SaaS products started by resolving a very narrow problem.

Execute a Service-Based Offering
Execute a Service-Based Offering to generate immediate cash flow and gain market intelligence, which are required when developing your SaaS product.
TK, founder of ToutApp, advocates for differentiating between a SaaS company (a complex “apartment building”) and a services business (a simple “lemonade stand”). If you possess relevant skills—such as software development, graphic design, digital marketing, or content creation—offer these as a direct service to your intended SaaS target market. This matches with Rob Walling’s “Stair Step Approach.”
Identify a service that directly relates to the problem your future SaaS will solve.
dentification et validation de votre marché cible sont essentielles :f your SaaS premise is a project management tool for small agencies, start by offering freelance project management consulting or setup services for existing tools. This will take care of several critical objectives:
- Generates immediate cash flow: These funds can be earmarked for future SaaS development costs, however minimal.
- Provides deep market immersion: Direct client work offers insight into customer workflows, pain points, and desired outcomes which is valuable data. TK leveraged this to build ToutApp.
- Builds relationships: Your service clients can become your first SaaS beta testers or paying customers.
This phase is less about maximizing revenue and more about deep learning and customer discovery. Document all feedback and recurring challenges your clients face.

Develop a Focused Minimum Viable Product (MVP)
Construct an MVP that includes only the absolute essential core feature(s) necessary to solve the primary validated problem for your initial users. The goal is to launch quickly to get real-world feedback, not to build a perfect, feature-rich product.
- If you are a developer: Dedicate focused time to build this. Simplicity is key.
- If you are not a developer:
- Seek a technical co-founder: Clearly articulate the value you bring (market validation data, an email list from your service business, UI/UX mockups, initial customer commitments).
- Utilize No-Code/Low-Code Platforms: Tools like Bubble.io, Softr.io, or an integrated stack (e.g., Airtable/Baserow for database, Pably Connect/n8n for automation) can create functional MVPs. Example: For an “AI-powered social media post generator,” the MVP might only support plain text generation for one platform based on 2-3 user-defined keywords, with no image capabilities or scheduling.
Consider different MVP approaches:
- Manual-First (Concierge/Wizard of Oz MVP): Before writing any significant code, try to deliver the core value of your SaaS manually. If you’re building a report generation tool, initially create the reports by hand for your first few “users.” This tests the value proposition and helps you understand the process deeply. Only automate what you’ve proven valuable manually.
- Single-Feature MVP: A product that does only one thing but does it very well for your specific niche.
Use UI/UX design tools like Figma ou Penpot (open source) to create interactive mockups. Test these with real users before development to determine usability issues early on. This feedback loop is really important.

Recommended Tools (Free Tiers/Open Source) |
Key Consideration |
|
Website/Front-end Hosting |
GitHub Pages, Cloudflare Pages |
Bandwidth limits, custom domain support, ease of deploy |
|
Back-end/App Hosting |
Heroku (free tier), Fly.io (free allowances), Digital Ocean (initial credit), Coolify (self-hosted) |
Scalability of free tier, database options, learning curve |
|
Database & Auth |
Supabase (PostgreSQL), Firebase (NoSQL) |
Data storage limits, concurrent connections, ease of SDK use |
|
Email Sending |
AWS SES (free tier), Mailgun (free tier) |
Send volume limits, deliverability, setup complexity |
|
automatisation |
Pably Connect (LTD often available), n8n (self-hosted) |
Number of tasks/integrations in free plan |
|
Service client |
Crisp (free tier), Tawk.to |
Number of agents, chat features |
|
Analytics |
Google Analytics, Plausible (if budget allows for paid after free trial) |
Simplicity vs. depth of data, privacy focus |
|
Payments/ Billing/ Subscription Management |
PayPro Global (often as Merchant of Record – MoR) |
Purely commission-based (percentage of sales), no fixed monthly/setup fees. MoRs handle sales tax/VAT. |
When self-hosting with tools like Coolify on a budget server (e.g., Hetzner), you are responsible for server maintenance and security, but gain more control and potentially lower long-term costs compared to managed platforms once you scale beyond free tiers. Be mindful of egress costs on major cloud providers like AWS.

Execute Lean Marketing Strategies
With no budget for paid advertising, your marketing must be organic, consistent, and value-driven.
- Marketing de contenu : Create truly helpful content (blog posts, guides, short videos) that addresses your target audience’s specific problems. Use Google’s “People also ask,” AnswerThePublic (free searches), or forum discussions to find relevant topics.
- SEO (Search Engine Optimization): Focus on long-tail keywords and niche-specific terms.
- Engineering as Marketing: As Simon Høiberg suggests, build small, free micro-tools or calculators that solve a tiny piece of your audience’s problem. These can drive organic traffic and act as lead magnets.
- Direct Outreach & Genuine Engagement: Participate authentically in online communities (niche subreddits, LinkedIn groups, industry forums). Offer help, share insights, and only mention your product when it’s a natural fit to solve a discussed problem. Avoid spamming.
- Community-Led Growth: Build your own small community from day one. Consider a simple Discord server, a private Facebook group, or an engaged email list. Build discussions, look for direct feedback, and make your early adopters feel like insiders since they often become your biggest advocates.
Self-assessment for marketing: “Where does my ideal customer spend their time learning and discussing their problems?” and “How can I provide significant value before asking for anything in return?“

Systematically Acquire Your First Users
Acquiring initial users without a marketing budget requires persistence, direct engagement, and a willingness to build based on their insights. Focus on getting first 100 customers:
- Leverage your service business network: Your existing service clients are your warmest leads.
- Structured Early Adopter Program: Offer a compelling incentive (e.g., 50-75% lifetime discount, extended free premium access) to a small, defined cohort of users (e.g., 10-20) in exchange for structured feedback (e.g., weekly calls, detailed surveys).
- Manual, Personalized Outreach: Find your ideal potential users on platforms like LinkedIn and send personalized invitations to try your MVP.
- Focus on Qualitative Feedback: When creating your business, engage in deep conversations with a few loyal users more than analyzing superficial metrics from many disengaged ones. Understand their “why.”
Finding the first paying customers is hard. Rob Walling emphasizes this. It will take time and direct effort. Keep asking for feedback and be prepared to pivot or adjust your product based on what you learn. Also, track simple metrics like activation rate (users completing a key action) and retention for your early cohort.

Reinvest Profits and Scale Methodically
As your service business or early SaaS MVP starts to create revenue, reinvest it with carefully into product improvement or low-cost growth initiatives. Adopt Rob Walling’s “Stair Step Approach“:
- Fondation: Your initial service business or a very simple, monetized product (e.g., a niche digital template, a small open-source project with a paid support tier).
- Croissance: Use profits and insights to methodically improve your MVP or expand your service to validate further SaaS features.
- SaaS Enhancement: With experience, a small cash buffer, and a validated customer base, enhance your SaaS product based on user feedback and data.
If your service business generates $200/month profit, you might reinvest $50 into a better analytics tool (once you outgrow free tiers) or $100 into a highly targeted, small-scale content promotion experiment.
Embrace all data from day one. Track user sign-ups, which features are used most/least, and why users churn. This information is key for prioritizing development and ensuring you’re building something people genuinely need and will pay for. The global SaaS market’s growth ($232 billion projected by 2025 by Gartner) shows opportunity, but success hinges on solving real problems effectively.
Conclusion
Successfully launching a SaaS business without money or financial backing is a marathon, not a sprint. It demands resourcefulness, a relentless focus on customer value, and the discipline to iterate based on real-world feedback. By validating rigorously, starting with service-based revenue if possible, building an ultra-lean MVP, utilizing free and commission-based tools, and focusing on organic growth and community, you can build a solid foundation for a sustainable SaaS business.
FAQ
-
Yes, if you use your own time and skills, utilize free and open-source tools, focus on organic marketing, and implement commission-based payment solutions. It does require resourcefulness and a lean approach with a focus on prioritizing validation and an MVP.
-
Vigourously validate your idea with real potential users to be certain you’re solving a genuine, urgent problem they’d be willing to pay for. This prevents wasting time on building something nobody needs.
-
You can use no-code/low-code platforms (such as Bubble, Softr) to build an MVP, or partner with a technical co-founder who is willing to work for equity. Or, start with a “manual-first” or “concierge” MVP where you offer the service manually before automating it.
-
Plan for organic methods such as content marketing (blogging, videos), SEO targeting keywords, direct outreach, community engagement in relevant online spaces, and building small, free “engineering as marketing” tools. Building genuine relationships and providing value upfront is necessary.
-
Use a Merchant of Record (MoR) service (like PayPro Global) that charge on a commission-only basis. MoR’s manage payments, subscriptions, and sales tax for a percentage of your sales, so there are no upfront or fixed monthly costs.
-
An MVP is the simplest version of your product with enough basic features to resolve a problem for early users from which to gather feedback. It’s necessary for no-money startups because it enables you to launch quickly, validate your core assumptions with little development effort, and expand based on real user data.
-
Many founders start as a sole proprietorship (or the equivalent in their country) which usually doesn’t require any upfront filing costs. Establish a formal company entity (like an LLC or corporation) once you begin generating revenue, have paying customers, or plan to take on partners or investment, since this often involves costs and administrative effort.
