Each short-stay property analysed inside its own regional micro-market, turning the benchmark into a prioritised action list — with the payment infrastructure fully migrated to Stripe.
FAQ
Frequently asked questions
How much does it cost to build a professional website?
It depends on scope. Landing pages start at USD 800, business websites from USD 2,000, and custom SaaS platforms are quoted after a free discovery call.
How long does it take to develop a SaaS?
An MVP takes 8 to 16 weeks depending on complexity. Business websites ship in 3-5 weeks and landing pages in 1-2 weeks. We work in two-week sprints with incremental deliveries.
Do you work with international clients?
Yes. We are based in Jacareí (São Paulo, Brazil) but serve clients across Brazil, the US, and Europe remotely. All meetings over Google Meet, deliverables via Git.
Can you integrate AI into my existing product?
Absolutely. We integrate OpenAI (ChatGPT), Anthropic (Claude), and other AI APIs into websites, SaaS apps, and legacy systems. We also build custom chatbots, autonomous agents, and n8n workflows.
Do I own the source code?
Always. You own the Git repository from the first commit. No black boxes — you get well-written, tested, documented code with CI/CD set up on your preferred provider.
What tech stack do you use?
Frontend: React, Next.js 15, TypeScript, Tailwind CSS, GSAP, Three.js. Backend: Node.js, Python, Django, FastAPI, PostgreSQL, Supabase. AI: OpenAI, Anthropic, LangChain, n8n. Deploy: Vercel, Railway, AWS.
