Questions

Frequently Asked

Everything you need to know before we start working together.

How much does a project cost?
+
Project costs vary based on scope, team size, and timeline. We offer both fixed-price and time & materials engagements. After a free discovery call we'll provide a detailed estimate within 48 hours — no commitment required.
How fast can you build an MVP?
+
Most MVPs are delivered in 8–12 weeks depending on complexity. We use a lean sprint model — you get a working, deployable product with core features, not a prototype. We can start within 1–2 weeks of signing.
Do you work with startups?
+
Absolutely. About 60% of our clients are early-stage startups. We understand the need to move fast, stay lean, and build something investors can evaluate. We also have experience working with equity-based or deferred payment models for seed-stage companies.
What engagement models do you offer?
+
We offer three models: Managed Project Delivery (outsourcing — we own the delivery), Dedicated Team Extension (outstaffing — your engineers, our talent), and Tech Talent Acquisition (recruitment into your own team). Most clients start with outsourcing and transition to outstaffing as they scale.
Who owns the code and IP?
+
You do — 100%, from day one. We sign IP assignment agreements as part of our standard contract. There is no vendor lock-in, no licensing fees, and no restrictions on how you use, modify, or sell the product we build for you.
How do you handle time zone differences?
+
Our teams operate in CET and US Eastern time zones, giving us real daily overlap with clients across Europe and North America. We maintain async-first communication with synchronous standups and weekly demos scheduled at your convenience.
Are you GDPR compliant?
+
Yes. GDPR compliance is built into our delivery processes by default — data handling, storage architecture, consent flows, and DPA agreements are all standard parts of how we work with EU and UK clients.
How much does it cost to build an AI SaaS product?
+
A typical AI-powered SaaS MVP ranges from $40,000 to $120,000 depending on the complexity of the AI pipeline, number of integrations, and required infrastructure. We provide a detailed breakdown after a free discovery call — usually within 48 hours.
Can you integrate GPT-4, Claude, or other LLMs into my product?
+
Yes. We work with all major LLM providers — OpenAI (GPT-4, GPT-4o), Anthropic (Claude), Google (Gemini), and open-source models via Hugging Face or self-hosted Ollama. We also build RAG pipelines, fine-tuning workflows, and agentic systems using LangChain and LlamaIndex.
What is the difference between outsourcing and outstaffing?
+
Outsourcing means Yarvixo owns the delivery — we provide a full team, manage the process, and deliver the product. Outstaffing means you hire individual engineers from our talent pool who work as an extension of your own team under your management. Both models are available and can be combined.
How long does it take to build a Web3 application?
+
A basic smart contract with a frontend dApp takes 4–8 weeks. A full NFT marketplace or DeFi protocol with audited contracts, multi-chain support, and a polished UI typically takes 12–20 weeks. Timeline depends heavily on audit requirements and the number of supported chains.
Do you provide smart contract audits?
+
We perform internal security reviews as part of every Web3 engagement. For production-grade contracts handling significant value, we recommend and facilitate third-party audits from specialist firms. We can help you select and coordinate with an auditor as part of the project.
What does a dedicated team engagement look like?
+
You get a pre-vetted team of 2–8 engineers, a tech lead, and optionally a QA engineer — fully integrated into your workflow, tools, and rituals. The team operates on your schedule, uses your project management tools, and reports directly to you. Minimum engagement is 3 months.
How do you ensure code quality?
+
Every project includes mandatory code reviews, automated testing (unit, integration, and E2E), CI/CD pipelines, and architecture review checkpoints. We follow OWASP security guidelines, enforce linting and type safety, and deliver full documentation alongside the codebase.
Do you sign an NDA before starting?
+
Yes. We sign an NDA at the start of any substantive pre-sales conversation where confidential information is shared. This is standard practice and requires no negotiation on your end — we use a straightforward mutual NDA that can be signed within 24 hours.
What industries do you specialise in?
+
Our strongest domain expertise is in SaaS, AI startups, Web3 / DeFi, gaming and full-cycle game development, fintech, and HealthTech. We also have experience in logistics automation and e-commerce infrastructure. We choose projects where we can bring genuine technical depth, not just execution capacity.
Can you help after the MVP is launched?
+
Yes. Most of our client relationships extend well beyond the initial MVP. We offer post-launch support packages covering monitoring, incident response, feature development, performance optimisation, and scaling. We can also transition the codebase to your in-house team with full handover documentation.
What tech stack do you use for SaaS products?
+
Our default SaaS stack is React or Next.js on the frontend, Node.js or Python on the backend, PostgreSQL or MongoDB for data storage, and AWS or GCP for infrastructure. We use Docker and Kubernetes for containerisation and Terraform for infrastructure as code. We adapt the stack to your requirements — we are not dogmatic about tooling.
How do I get started?
+
The fastest path is to book a free 30-minute discovery call via our Calendly link or fill in the contact form below. We will review your project brief within one business day and come prepared with initial thoughts, relevant case studies, and a proposed next step — no commitment required.
Do you work with non-technical founders?
+
Absolutely. Many of our clients are business founders or domain experts without a technical background. In these cases we take on a stronger advisory role — helping define the architecture, select the right tools, and translate business requirements into technical specifications. You do not need to know how to code to work with us effectively.
