Why does SLOW exist?
The origin is personal. In 2023, Sascha started as someone who wanted to deliberately optimize his own health. In doing so, he experienced firsthand how high the barriers are on both sides. Clients seek a seamless and understandable experience, while health professionals want to provide exactly that experience. This became the catalyst to explore more deeply how a health optimization platform could bring both sides together.
What is SLOW?
SLOW is the leading B2B2C platform for Precision Longevity in the DACH region. It connects health professionals with their clients through AI-supported, clinically tested health protocols based on individual biomarker and lifestyle data.
Where practices previously moved between laboratories, anamnesis tools, Excel, supplement suppliers and wearable apps, SLOW bundles diagnostics, analysis, protocol creation, supplement ordering and client support in a single platform. Health professionals reduce their effort per protocol by a factor of 10+, while clients experience longevity as a lived routine rather than a stack of recommendations.
Behind SLOW is SLOW Health GmbH with a clinical advisory board led by Thiemo Osterhaus.
What is the SLOW Practitioner Portal?
The SLOW Practitioner Portal is the central workspace for health professionals. Client management, lab analysis, protocol creation, diagnostics ordering, and outcome tracking all come together in one system.
Instead of switching between 5–10 tools, you work in a single interface. Lab PDFs are automatically read by the SLOW Extraction Engine, AI analysis reveals patterns in findings, and the protocol builder creates a clinically reviewed plan in under 20 minutes. Diagnostics, supplements, and additional services are ordered directly through our partners.
The portal is the counterpart to the client app SLOW Concierge. What you enable here becomes part of your clients' daily routine there.
What is SLOW Concierge
SLOW Concierge is the client app that pairs with the Practitioner Portal. Your health clients use it to implement their protocol in daily life. This includes tasks, supplement plan, habit tracking, wearable and lab data, plus an AI coach that supports them between consultations. Adherence and outcomes flow back to your Practitioner Portal in real time.
What is the SLOW Score?
The SLOW Score is a three-level longevity index that condenses biomarkers, lifestyle, and habit data into a single, comparable value per client.
The calculation is transparent across three levels: individual biomarkers are classified (for example HbA1c, Vitamin D, hsCRP, ApoB), aggregated into health domains (metabolism, inflammation, hormones, cardiovascular and others), and weighted together to form the final SLOW Score. The weightings are evidence-based and are continuously validated by the clinical advisory board led by Dr. med. Thiemo Osterhaus.
No black box: every health professional sees in the portal which biomarkers and domains influence the score and how · and can explain this logic to clients.
Who is SLOW for?
SLOW is designed for health professionals: doctors, naturopaths, functional medicine practices, and longevity coaches who support their clients with data-driven insights. Clients have access to a companion app.
How does SLOW's AI-powered health analysis work?
SLOW combines large language models with a curated database of biomarkers, along with referenced content from scientific databases such as PubMed, Cochrane, and clinical guidelines. This is complemented by continuous validation from the SLOW Advisory Board, led by Dr. med. Thiemo Osterhaus.
The process works as follows: labreports are read and normalized by the SLOW Extraction Engine, linked with client medical history, and analyzed by the AI for patterns, deficits, and risks. The result is not a finished protocol, but a structured proposal with findings interpretation, areas for action, and supplement and habit recommendations.
Every output is reviewed, adjusted, and approved by a health professional. Practitioner-in-the-loop is non-negotiable.
Does responsibility remain with me?
Yes, entirely. SLOW is a practitioner-in-the-loop system: every AI output is a suggestion, every therapeutic recommendation is reviewed and approved by you as a health professional.
In practical terms: the AI analyzes, structures and makes suggestions – but no protocol is delivered to clients without you having reviewed it, adapted it, and actively activated it. The SLOW Concierge App displays only approved content. Currently SLOW is not a medical device. MDR certification is planned for mid-2027.
Responsibility lies with the qualified user.
What does SLOW cost?
The platform launches free of charge. Tests are billed per assignment, and the Practitioner subscription scales with the number of active clients. Details will follow at launch. For advance information, please email hello@slow.health
What is your approach to data protection?
Data is processed in compliance with GDPR within the EU. Clients retain control over their health data and can revoke access at any time.
