About 6th Technology

A sixth way to care for the mind

6th Technology is a mental health technology company in Sofia, Bulgaria. We run audio-visual entrainment (AVE) sessions in our own practice office, measure what they do, and package what works into a free app: 6th Mind.

Why "Sixth"

Five usual answers, and the one we work on

When people struggle with low mood, anxiety or sleep, help usually comes from one of five places. They work for many people, and leave many others behind. The sixth is non-invasive technology that acts on the brain directly. Of those methods we chose AVE, light and sound, for its safety profile.

The full story behind the name

1
Body

Exercise and sleep change the brain's chemistry.
2
Emotion

Time with people and things that feel good loosen negative loops.
3
Mind

Reasoning and meditation quiet painful thoughts.
4
Method

Structured programmes like CBT and ACT.
5
Biochemistry

Medication shifts brain chemistry, with the most care needed.
6
Technology

Light and sound that guide brain rhythms, with nothing to swallow and nothing on the skin.

How we work

From the practice office to your phone

01 · Practice office

Sessions with people, in Sofia

A psychotherapist runs AVE sessions in our office next to the Zdrave 33 practice, with a consulting psychiatrist when needed. EEG is recorded for two minutes before and after every session.

02 · Measurement

We keep what the data supports

1000+: AVE sessions with 170 people
≈80%: of programmes with 10+ sessions improved on our EEG baseline index (n≈70). Not every programme runs that long.

03 · The app

6th Mind, free for everyone

The protocols that hold up become the 36 sessions in 6th Mind. You can also hear them in the browser, build your own in the Session creator, or add themed Mental 6-packs.

What we hold to

Principles

Evidence first

Every session in the app comes out of our own practice, where EEG is recorded before and after each one. We build on published AVE research and say which studies we rely on.

Honest about the limits

Our figures come from our practice, not from a randomised trial, and we say so. We show the denominators, and we don't promise cures.

A complement, not a replacement

AVE works alongside professional care. If you are in treatment, keep your doctor in the loop. Light sessions are not suitable for people with epilepsy.
