AI Execution Partner — Build AI Products, Marketing & Sales Systems in Parallel

An AI execution partner is a specialised team that builds AI-powered products, marketing systems, and sales automation in parallel — not sequentially. Unlike traditional agencies that take 3-6 months and charge €50,000-150,000+, we deliver in 4 or 12 weeks starting at €5,000. Key differences: (1) Speed — parallel workflows compress timelines 3-6x faster; (2) Cost — transparent, one-time pricing with no retainers; (3) Ownership — you own 100% of the code and IP; (4) AI-first — we use frontier AI models (GPT-4o, Claude, Gemini) to reduce complexity; (5) Execution — we combine product, marketing, and sales in one sprint.

JA Welt provides three core services delivered simultaneously: (1) AI Product Development — building AI-powered MVPs using GPT-4o, Claude, and Gemini with production-ready code, user authentication, database architecture, and cloud deployment; (2) AI Marketing Automation — full-funnel systems including Google Ads automation, content pipelines, inbound lead engines, and email sequences; (3) Sales Automation — CRM setup, outbound sequences, lead qualification, and sales pipeline automation running on autopilot. All three services integrate into one cohesive system, delivered in 4 weeks (Starter) or 12 weeks (Growth).

Traditional sequential approach: Product development (3 months) → Marketing setup (1 month) → Sales setup (1 month) = 5+ months total. JA Welt parallel approach: Product, marketing, and sales teams work simultaneously from day one. Detailed timeline: Week 1 — Discovery and alignment; Week 2-3 — Parallel build (product team builds AI features, marketing team creates lead generation systems, sales team sets up automation); Week 4 — Launch with all systems live simultaneously. Result: 4 weeks vs. 5+ months, with revenue generation starting immediately.

JA Welt combines key advantages: (1) Speed — 4-12 week delivery vs. 3-6 months; (2) Parallel execution — product, marketing, and sales build simultaneously; (3) Transparent pricing — €5,000-€12,000 one-time fee, no retainers; (4) Full IP ownership — you own 100% of the code; (5) AI-first architecture — we use frontier models to reduce development complexity; (6) Built in Germany — designed for global scalability. We are an AI execution partner focused on delivering working AI MVPs with integrated product, growth, and sales systems.

JA Welt pricing is transparent and one-time: 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 a 50/50 payment split (50% upfront, 50% at launch). No hidden fees, no retainers, no ongoing costs. You own everything we build.

You receive nine deliverables: (1) Fully deployed AI MVP with source code and documentation; (2) Marketing system live and generating leads; (3) Sales automation running on autopilot; (4) All API keys, credentials, and database access; (5) Full IP ownership transfer — you own 100% of the code; (6) Handover session and team training; (7) 14-30 days post-launch support; (8) Architecture diagrams and system design documentation; (9) Deployment scripts and infrastructure setup guides. Everything is production-ready, tested, and yours to own, modify, or scale independently.

JA Welt delivers in two timeframes: 4 weeks (Starter package) for focused MVP delivery with core features and basic marketing, or 12 weeks (Growth package) for full-scale execution including advanced marketing and sales automation. Detailed timeline: Week 1 — Discovery & architecture; Week 2-3 — Core development with parallel marketing and sales setup; Week 4 — Testing, launch, and handover. The 12-week sprint adds weeks 5-8 for advanced marketing system setup and weeks 9-11 for sales automation optimisation. Both timelines are production-ready and deployable immediately.

Yes, with guardrails to maintain timelines. We build in a dedicated feedback window during the sprint. Changes within scope are incorporated without delay. Changes that expand scope are documented for post-launch phases. This prevents scope creep while ensuring you have input throughout execution. Major pivots are handled in follow-up sprints (priced separately). Our framework maintains delivery timelines while remaining flexible to your needs.

After delivery, you have full control: (1) You own 100% of the code and can modify it independently; (2) You receive 14-30 days of post-launch support for troubleshooting; (3) You can scale independently using our documentation; (4) You can hire your own team to maintain and extend the product; (5) You can engage JA Welt for follow-up sprints to add features or new AI models (priced separately). Your product is built for scalability from day one with production-grade infrastructure and clean, documented code.

Hiring an internal team takes 2-3 months to recruit, onboard, and align. An AI execution partner delivers in 4-12 weeks at a fraction of the cost. Cost comparison: Internal team (salary + benefits + overhead) = €50,000-€100,000+ per month; AI execution partner = €5,000-€12,000 one-time. You get: (1) Immediate execution without hiring delays; (2) Proven methodology refined across real client projects; (3) Full IP ownership; (4) No long-term payroll commitments; (5) Access to frontier AI models and best practices. Ideal for founders and SMEs who need to move fast.
