Sensay

What is Sensay?

Sensay is a platform that uses AI to create digital versions of people — digital twins that capture a person’s likeness, memories, stories, and personality. It is designed in part to help people with dementia by letting them interact with digital replicas of loved ones. Beyond that, Sensay aims to make information more accessible through a network of experts who share insights and advice across a range of topics.

The platform is built on blockchain technology, which provides security, transparency, and decentralization, with additional measures to protect user data and assets. Reviewers have praised its approach, ease of use, and potential in areas like customer service, entertainment, and education.

Sensay’s stated goal is to build a digital legacy for everyone: personal digital twins that replicate human knowledge, voice, and image, preserving personal wisdom over time.

Who created Sensay?

Sensay was founded by Dan Thomson, a serial entrepreneur, speaker, and author. The co-founders are Marco Bettiolo (CTO), Roman Shportko (CSO), and Shane Sibley (CBDO), each contributing experience in technology development and strategy. The company also has an advisory board with experts in medical advising, business, management, and AI ethics.

What is Sensay used for?

Sensay’s core applications include:

• Dementia support — creating replicas of familiar people to help preserve memories for individuals with dementia
• Senior care and mental health — supporting well-being through companion-style AI
• Custom replicas — tailoring digital versions of people for specific needs
• Education — sharing knowledge globally, around the clock, in any language
• Fan engagement — increasing interaction between public figures and their audiences

The AI models adapt over time, improving accuracy and interaction quality with use.

Key takeaways

Sensay combines AI replication with blockchain-based security to create digital twins of real people. Its most distinctive use case is dementia support, where replicas of loved ones can help preserve memories, but the platform also serves education, fan engagement, customer service, and long-term digital legacy preservation. An advisory board covering medicine, business, and AI ethics guides its approach to the privacy and philosophical questions raised by digital replicas.
