I build focused, profitable SaaS products for solo founders and small teams. One problem, one solution, one subscription -- live and earning within 4-6 weeks.
Micro-SaaS is a small software product that solves one specific problem for a niche audience. Unlike enterprise SaaS that takes 12-18 months and EUR 100,000+ to build, a micro-SaaS can launch in 4-6 weeks for EUR 1,500-7,000 and reach profitability with just 50-200 paying customers.
The economics are simple: a product charging EUR 29/month needs only 70 customers to generate EUR 2,000/month in recurring revenue. With low hosting costs (EUR 20-50/month) and zero employee overhead, micro-SaaS products deliver exceptional margins.
I am Kirill Strelnikov, a freelance SaaS developer based in Barcelona. I have built micro-SaaS products including a multi-tenant time-tracking platform for HoReCa, AI-powered analytics tools, and e-commerce platforms. I focus on getting your product to the first paying customer as fast as possible -- not building features nobody asked for.
Scheduling for specific industries, invoice generators, project trackers, review management, inventory tools. Focused on one vertical, solving one pain point better than horizontal tools.
Content generators, data analyzers, document processors, chatbot builders. Add AI to a niche workflow and charge a premium for it. LLM costs are your moat -- custom beats generic.
Connect two tools that do not talk to each other. Sync data between platforms. Automate a manual process. If people use spreadsheets and Zapier for it, you can build a SaaS for it.
Every micro-SaaS I build includes the foundational infrastructure that takes months to build from scratch:
Why Django? Django is the fastest framework for building SaaS products. Built-in auth, admin, ORM, and security save 4-6 weeks of development compared to Node.js or Rails. Django powers Instagram, Pinterest, and Disqus -- it scales to millions of users. For a micro-SaaS, it is overkill in the best possible way.
Why not no-code? No-code tools (Bubble, Softr) work for prototypes but hit walls at scale: slow performance, limited customization, vendor lock-in, and monthly costs that eat your margins. A custom Django SaaS costs EUR 20-50/month to host, never limits your features, and you own the code.
Before writing code, we validate demand. I build a landing page with waitlist signup and help you run a small test. If people sign up, we build. If not, you saved thousands. This phase is optional but recommended for first-time founders.
I define the minimum viable product: which features make the cut, which wait for v2. We agree on deliverables, timeline, and fixed price. I push back on feature creep -- shipping fast matters more than shipping perfect.
Weekly demos so you see progress. Core product first, then billing, then landing page. You can start inviting beta users by week 3. Changes and feedback are incorporated in real-time.
I deploy to production, set up monitoring, and help with your launch strategy. After launch, I offer monthly retainer for bug fixes, feature additions, and scaling. Most micro-SaaS products need 2-3 months of iteration after launch to find product-market fit.
