Inside Epignosis’ 250-Person AI Agent Rollout with Mindstone

Mindstone has released its AI agent platform Rebel as fair source following the completion of a company-wide deployment at Epignosis, the learning technology company behind TalentLMS.

The announcement comes after all 250 employees at Epignosis were equipped with personalised AI agents connected to a shared organisational memory, enabling staff across engineering, sales, finance, product and customer success to automate work and access company knowledge more effectively.

Developed by Mindstone, Rebel is designed to help organisations move beyond isolated AI experiments by connecting employees to AI agents that draw on shared company memory. The platform integrates with existing business tools, including email, CRM systems, calendars, Slack and documents, while enabling knowledge and workflows created by one employee to be shared across teams.

Mindstone said the system was designed by CTO Greg Detre, co-founder of Memrise and former Chief Data Scientist at Channel 4. Detre’s background in cognitive neuroscience helped shape Rebel’s approach to organisational memory, inspired by how the brain consolidates experiences into long-term memory.

Rebel has already been deployed across organisations including Epignosis, Memrise and YAP Media. According to Mindstone, the recent rollout at Epignosis has generated the equivalent capacity of eight full-time employees within 12 weeks, allowing resources to be redirected towards growth initiatives and competitive advantage.

“One of our employees told their manager at an OKR review that their targets were undeliverable. By the end of the quarter, after Rebel had automated the bulk of the underlying work, they over-delivered. We have seen this across the company. The border between learning and doing is fading out – and that changes everything about how you scale. Just software won’t get you there. You need service, training, transformation and a system that gets smarter the more people use it.” said Dimitris Tsingos, CEO of Epignosis.

The company said adoption spread organically, with employees dubbing the phenomenon the “potatoes effect”, as colleagues sought access after seeing the results achieved by others. Staff across marketing, finance and customer support reportedly began creating automated workflows within days, despite having no engineering background.

Mindstone points to wider industry challenges in AI adoption. An MIT study found that 95% of enterprise AI pilots fail to generate measurable financial impact, largely because organisations struggle to embed AI into everyday workflows.

Rebel has been built to address that challenge through shared organisational memory, portability across AI models and built-in governance controls. Access permissions determine what information employees can access, while actions such as sending emails, updating records or modifying files require explicit user approval. The platform can also operate entirely on-device, ensuring data never leaves a user’s machine.

Joshua Wöhle, CEO and Co-Founder of Mindstone, said many businesses continue to mistake access to AI tools for a coherent AI strategy.

“Many companies are currently thinking that buying 500 ChatGPT licences translates into an AI strategy. It’s not. It’s 500 individual experiments with no memory and no connection to each other. Rebel is the difference between having an assistant and having a chief of staff: it knows your company, it learns from everyone in it, and it gets more useful every day you use it. We’re fair-sourcing it because the benefit of AI should accrue to everyone, not just to whoever can afford the biggest vendor contract.”

Rebel is available from today under a fair-source model. The platform’s personal core is free for individuals and organisations with up to 100 users, with workflows stored in portable file formats. Organisations with more than 100 users can access a Pro tier that includes adoption tracking, ROI measurement and ongoing transformation support.
