CTO & Board Member · SIMPLITO

Bridging privacy, AI ethics & secure collaboration.

I’m Błażej Zyglarski — technologist, lecturer and maker from Toruń, Poland. I lead a team of around thirty engineers building private AI and end-to-end encryption tools, and I’ve spent two decades teaching the next generation of developers how to build software that respects the people who use it.

What I do

Three threads, one conviction

Everything I build or teach comes back to the same idea: technology should serve people without surveilling them.

01

Private, sovereign AI

At SIMPLITO I direct the development of DeepFellow — a complete, self-hosted AI system for organisations in regulated sectors that cannot ship their data to someone else’s cloud. Full data sovereignty, compliance support and an OpenAI-compatible API, on infrastructure you control.

02

End-to-end encrypted collaboration

PrivMX is a stack-agnostic platform for implementing cryptography in universal environments — web, native, mobile, IoT, VR. It lets developers add end-to-end encrypted communication and storage to any product without becoming cryptographers.

03

Teaching & community

Since 2009 I have lectured at the Faculty of Mathematics and Computer Science of Nicolaus Copernicus University, served as Vice-Dean for Computer Science, and helped grow the local tech community through meetit.live. More about my mission →

Selected work

Products built on privacy by design

Two product lines from SIMPLITO — one for encrypting what people share, one for keeping AI inside the organisation that uses it.

End-to-end encryption platform

PrivMX

Developer-friendly, end-to-end encryption for any digital environment. Build and integrate apps with secure communication and storage across web, mobile, AR, VR, IoT and more — with the keys staying with the users.

  • Stack-agnostic SDKs: web, native, mobile and embedded
  • Encrypted threads, stores, inboxes and streams as building blocks
  • Zero-knowledge architecture — the server never sees plaintext
Private AI infrastructure

DeepFellow

A privacy-first AI infrastructure framework: production-ready, self-hosted deployments with full data sovereignty, compliance support and total control of privacy and costs — for banks, healthcare, public administration and anyone else who cannot send data out.

  • Runs entirely on your own infrastructure
  • OpenAI-compatible API — existing tooling just works
  • DeepFellow Workspace for everyday team use
Privacy isn’t a feature you bolt on at the end. It’s the architecture you start from.
