A verdict you can defend.
Any AI can make any idea sound viable — that's exactly the problem. Ainna scores against a published methodology with human experts in the loop, so a yes is worth acting on — and a no just saved you three months of building the wrong thing.
The Innovation Mode
Ainna has The Innovation Mode at its core — a methodology shaped by 25 years of innovation work across industries and markets, published by Springer Nature, and now in its 2.0 edition with a strong focus on AI and agentic corporate innovation. Ainna knows which questions to ask, how the dimensional scoring serves as a baseline for improvement, and when human judgment must enter the loop. Ainna is built on agentic technologies — a patent-pending, AI-native system. Anyone can wrap a prompt around a model; Ainna applies published methods with growing university adoption that make the verdict defensible — to you, and to your stakeholders.
