Taju Labs is a B2B development partner for neurotechnology and biosensing.
We build customized, multimodal sensing and analysis solutions — proprietary
hardware and software — for the companies and research groups turning brain
and body data into products.
We close the gap between the laboratory and the market.
Wearable noninvasive neurotechnology is full of results that never leave the
bench. Taju Labs takes brain- and body-sensing technology from an early
research stage and develops it into hardware, software and AI-solutions that
a partner can manufacture, certify and sell.
Vision
Improving human wellbeing and health through neurotech and biosensing innovation — moving brain and body monitoring out of the lab and into everyday life.
Mission
Providing best-in-class support to players in neurotechnology, through deep know-how in technology and product development for research, consumer and clinical applications.

Where Taju Labs works · from proof of concept to ready for launch
Expertise
Four disciplines, one team.
Sensing hardware, data science, development process and regulatory
strategy are usually four separate suppliers. We cover them together,
which is why the handover between them stops costing you time.
Multimodal sensing hardware
Miniaturized, battery-powered instruments for non-invasive brain and body measurement — from optode and electrode front ends to complete wearable systems and body-area networks.
fNIRS
HD-DOT
EEG / ExG
Oximetry
IMU
Firmware
Signal analysis & machine learning
Physiological modeling, non-stationary multimodal signal fusion and data-driven biomarker extraction — including hardware–AI co-design, where the algorithm shapes the instrument rather than following it.
Signal processing
Sensor fusion
Deep learning
Biomarkers
Product development & project management
Requirements, architecture, risk and verification planning through to design transfer — plus interim and project management for teams that need experienced hands on a critical program.

Approach
Scoped up front. Transferred cleanly.
Every engagement is defined before it starts — deliverables, ownership of
intellectual property, and the form the results take when they reach you.
No open-ended retainers, no ambiguity about who owns what.
Scope
We agree on the technical target, the interfaces and the constraints in a written statement of work. IP ownership is stated explicitly, per project, before any work begins.
Develop
Taju Labs leads the development, working with a team drawn from our own resources, yours, and specialist external partners where a project needs them.
Transfer
Results are handed over as a device master record — optionally with the full design history file — so your organization can manufacture, certify and maintain the product independently.
Ways to work with us
OEM development partnership
Customer-specific development of hardware, firmware and analysis software on the basis of our own technology stack.
Technology & project consulting
Feasibility studies, roadmap and design reviews, decision management, and interim project or program leadership.
Research collaboration
Taju Labs as the industry partner in publicly funded consortia, including support with grant applications and technical work packages.
Founders
A commercial engineer and a research engineer, working on the same problem from both ends.
Taju Labs was founded by two electrical engineers whose careers converged on
the same question: why does so little brain- and body-sensing technology ever
become a product?
Chief Executive Officer · Co-founder
Sebastian Kallenbach
Dipl.-Ing. Electrical Engineering
Sebastian has spent more than fifteen years developing active medical
devices up to class IIb and III, from implantable and extracorporeal
cardiac support systems to multi-spectral endoscopy platforms. He has led
electronics departments, run development programs with teams across
several international partners, and taken products through CE
certification and FDA submissions. At Taju Labs he owns commercialization,
program and project management, regulatory supervision and business
development.

Alexander heads the Intelligent Biomedical Sensing Lab at TU Berlin's
Machine Learning department and BIFOLD and is a visiting researcher at
Boston University's Neurophotonics Center. He has more than fifteen years
of experience in development of wearable neurotechnologies and signal
analysis using machine learning across positions in both industry and
academia. He was Chief Science Officer and R&D Director at NIRx Medical
Technologies, and previously CTO of Crely Healthcare. He sits on the board
of the fNIRS Society and contributes to the international ISO/DIN fNIRS
standard. At Taju Labs he owns the technology vision, the technology stack
and the transfer of research results into the company.
