Founded by Builders,
Run by Engineers
DemanualAI exists because the AI market has too many consultants and not enough builders. We're engineers who turned technical expertise into a product development company.
Our Philosophy
Build Products, Not Presentations
We don't make slide decks about AI—we write code, train models, and deploy systems. Every product we showcase is live, working, and processing real data.
Open-Source First
70% of our solutions use battle-tested open-source frameworks. Cost-efficient, transparent, and fully customizable. Proprietary tech only when it genuinely adds value.
Ship MVPs Fast, Scale Smart
90-day timeline from concept to production isn't aspirational—it's proven. Focus on core value first, optimize based on real usage, not assumptions.
Maintain What We Build
Most agencies disappear after launch. We provide ongoing maintenance, monitoring, and evolution. 18-month partnership track record proves we're in it for the long term.

How We Work
We're a lean team of specialized engineers. No account managers, no sales layer, no junior developers learning on your project. You work directly with the people building your product.
What makes us different:
- • Technical depth: Custom ML models, not just API integration
- • Full-stack capability: We handle everything from models to deployment
- • Maintenance commitment: 99.7% uptime across systems we maintain
- • Cost consciousness: Open-source first approach saves clients 85% on average
