Sleep, made simple.
DELIM is a sleep startup from Reading, UK. We make DELIM Mouth Tape, write plain-English guides on sleep and nasal breathing, and we’re building an AI agent that helps you sleep better.
We help you sleep better in every phase: before bed, through the night, and the moment you wake.
Most sleep advice is too general, or buried in long articles. We keep it short and clear, and we point you to simple tools that can help.
We give general sleep guidance, not medical advice. When something sounds serious, speak to your GP. Questions? Say hello.
From one small strip to better nights.
DELIM started with one common problem: sleeping with your mouth open and waking up with a dry mouth. Our first product was hypoallergenic mouth tape, and it taught us a lot.
The biggest lesson came from the questions people asked us. Why do I snore? Is mouth tape right for me? What else can I try? Every night is different, and the same few answers don’t fit everyone.
So we write guides that answer those questions in plain words, and we’re building DELIM Sleep AI, an agent that answers your own sleep questions and suggests what to try.
We’re a small team in Reading, UK, and we’re just getting started. Say hello any time. We read every email.
Three promises.
Clear answers, not noise.
Short, plain answers to real sleep questions. No jargon, just what helps.
Safety comes first.
We give general sleep guidance, not medical advice. When something sounds serious, see your GP.
Every phase of your night.
Sleep doesn’t start when you close your eyes. We help with winding down, sleeping through and waking up well.
