Northwind for iPhone

The voice confidant for founders.

You can’t tell your team. Your investors are the last people to ask. Your co-founder is half the problem. This is where it goes.

Built on approaches with decades of research behind them — why saying it out loud works.

Why out loud

Saying it out loud isn’t a trick.

The core of Northwind is one of the most replicated ideas in psychology: a weight you can hear yourself name is a weight you can think about.

Naming a feeling quiets it

Affect labeling — putting a feeling into words — reduces amygdala response to distressing stimuli. Saying “I’m afraid we’ll miss payroll” does something silently worrying never does.

Lieberman et al., Psychological Science (2007)

Disclosure is processing

Four decades of expressive-disclosure research show that translating stressful experiences into language — spoken or written — improves how people cope with them.

Pennebaker & Beall, Journal of Abnormal Psychology (1986)

Distance clears the view

Talking a problem through from a step back — the way you would to a confidant — improves regulation and judgment under stress compared with silently ruminating on it.

Kross et al., Journal of Personality and Social Psychology (2014)

Northwind is a confidant, not a clinician. It isn’t therapy, and when a human is the right call, it says so.

The obvious question

You could just use ChatGPT. Founders don’t, for three reasons.

It forgets you between Tuesdays.One continuous memory. It knows what you said in May when you circle back in August.
It agrees with everything you say.It pushes back. Built to notice avoidance and name it — like a co-founder, not a fan.
Your worst night becomes someone's training data.Never anyone's training data. An open model running under our instructions, and conversations that live only on your phone.

Built for one job — the founder conversation you can’t have anywhere else — instead of every job.

Private by design

What you say here stays here.

No account, no cloud copy. Conversations live encrypted on your phone, not our servers. What we never had can’t be produced — by us or anyone.

Three named companies, one job each. Mistral turns your speech into text, Cerebras writes the reply, Fish Audio speaks it. We keep none of it, and nothing trains on your words.

If we ever shut down or sell: export, then destroyed. Never an asset in a deal.

The full architecture — where your words go, encryption, the covenant — is on the privacy page.

When the light ends

The app picks up where the day leaves off.

Talk it through tonight. Decide in the morning.
