AI Product Building Timelines & Costs — Transparent Pricing Guide

Timeline depends on scope and complexity: Simple AI MVP (chatbot, content generator) = 4 weeks; Medium complexity (AI-powered SaaS with integrations) = 8-12 weeks; Complex system (multi-model AI with custom infrastructure) = 12-16 weeks. JA Welt delivers in 4 weeks (Starter) or 12 weeks (Growth). Timeline includes: Week 1 — Discovery and architecture; Week 2-3 — Core development; Week 4 — Testing and launch. All deliverables are production-ready and revenue-generating from day one.

Key factors that impact timeline: (1) Scope — number of features and integrations; (2) AI model complexity — simple models (GPT-4o for chat) vs. custom models; (3) Data requirements — training data preparation and processing; (4) Integrations — third-party APIs (Stripe, Zapier, CRM); (5) Infrastructure — cloud setup and deployment; (6) Team alignment — clear requirements and decision-making speed. JA Welt compresses timelines through parallel workflows and ruthless scoping focused on revenue-generating features.

JA Welt pricing: Starter package (4 weeks, AI MVP + basic marketing + CRM) = €5,000; Growth package (12 weeks, full execution with advanced marketing and sales automation) = €12,000; Scale package (enterprise custom pricing). For projects above €8,000, we offer 50/50 payment split (50% upfront, 50% at launch). Costs include development, deployment, documentation, and 14-30 days support. No hidden fees. You own 100% of the code.

Included in every package: (1) AI model integration and optimisation; (2) User interface design and development; (3) Database architecture and security; (4) Third-party API integrations (Stripe, Zapier, etc.); (5) Cloud deployment (AWS, Vercel, or your infrastructure); (6) Full source code and technical documentation; (7) Security audits and testing; (8) Handover session and team training; (9) 14-30 days post-launch support. Not included: ongoing hosting costs (minimal, typically €50-200/month), third-party API fees (Stripe, OpenAI, etc.), custom domain registration.

Traditional software development: 6+ months, €50,000-150,000+, sequential workflows, often requires ongoing retainers. JA Welt AI product development: 4-12 weeks, €5,000-12,000, parallel workflows, one-time fee. Cost difference: JA Welt is significantly cheaper and faster. Key reasons: (1) AI-first architecture reduces complexity; (2) Parallel workflows compress timelines; (3) Proven framework eliminates rework; (4) No retainers or ongoing costs.

Cost drivers: (1) Feature scope — more features = higher cost; (2) AI model selection — frontier models (GPT-4o) vs. open-source models; (3) Data requirements — training data preparation; (4) Integrations — number and complexity of third-party connections; (5) Infrastructure — custom vs. standard deployment; (6) Timeline — faster delivery may require more resources. JA Welt uses ruthless scoping to keep costs low while delivering revenue-generating features.

Yes. For projects above €8,000, we offer a 50/50 payment split: 50% upfront to start development, 50% at launch. This allows you to manage cash flow while we deliver. No interest charges or hidden fees. Payment is due before deployment. For enterprise projects (Scale package), we can discuss custom payment arrangements.

You own 100% of the code, so you can: (1) Make changes independently using our documentation; (2) Hire your own team to maintain and extend; (3) Engage JA Welt for follow-up sprints to add features or new AI models. Follow-up sprints are priced separately based on scope. We provide 14-30 days of post-launch support included in your package. Your AI product is built for scalability and modification from day one.

Start with these questions: (1) What is your core AI use case? (2) How many features do you need at launch? (3) What third-party integrations are required? (4) Do you have existing data or APIs to integrate? (5) What is your launch deadline? Based on your answers: Simple MVP = Starter package (4 weeks, €5,000); Medium complexity = Growth package (12 weeks, €12,000); Complex system = Scale package (custom pricing). Schedule a discovery call to get a precise estimate.

Three key advantages: (1) Parallel execution — product, marketing, and sales build simultaneously, not sequentially; (2) AI-first architecture — frontier AI models (GPT-4o, Claude, Gemini) reduce development complexity and time; (3) Proven sprint framework — refined across real client projects, eliminating rework and delays. Result: 4-12 weeks delivery at €5,000-12,000 vs. 6+ months at €50,000+ with traditional agencies.
