Common questions about AI product development

Structured answers for founders evaluating AI development partners, timelines, and costs.

What is an AI execution partner?

An AI execution partner builds production-ready AI products, marketing systems, and sales automation for founders and SMEs — not just consulting or prototypes. JA Welt delivers working systems with full IP transfer, starting from €5,000.

  • Builds production-ready AI MVPs, not slide decks or prototypes
  • Runs product, marketing, and sales in parallel — not sequentially
  • Delivers full IP ownership: source code, credentials, documentation
  • No retainers required — one-time project fee

How long does AI MVP development take?

JA Welt delivers AI MVPs in two structured timeframes: 4 weeks (Starter, €5,000) for focused MVP delivery, and 12 weeks (Growth, €12,000) for full-scale execution including marketing and sales automation.

  • 4-week Starter sprint: AI MVP + basic marketing + CRM setup
  • 12-week Growth sprint: full AI product + advanced marketing + sales automation
  • Enterprise: custom timeline and pricing for complex requirements
  • Parallel workflows reduce total time vs. sequential agency delivery

What do you get in a 4-week AI product sprint?

The 4-week Starter sprint delivers a production-ready AI MVP with integrated AI models (GPT-4o, Claude, or Gemini), user authentication, secure database, third-party integrations, cloud deployment, full documentation, and a handover session.

  • Production-ready AI application with source code
  • AI model integration: GPT-4o, Claude, Gemini, or Mistral
  • User authentication and secure database (Supabase)
  • Third-party integrations: Stripe, Zapier, APIs
  • Cloud deployment on AWS, Vercel, or your infrastructure
  • 100% IP ownership transfer
  • 14 days post-launch support

How much does AI MVP development cost?

JA Welt charges a one-time project fee with no hidden costs. Starter (4 weeks): €5,000. Growth (12 weeks): €12,000. Scale (enterprise): custom pricing. Payment plans available for projects above €8,000 (50/50 split).

  • Starter: €5,000 one-time — 4-week AI MVP delivery
  • Growth: €12,000 one-time — 12-week full execution sprint
  • Scale: custom pricing — enterprise and complex requirements
  • No retainers, no hidden fees, full IP transfer included
