call your cofounder. click and she picks up. hang up with your workspace built. she runs on Neptyn 1.0.

what she does

a cofounder who runs

she runs with her own agenda between your sessions: finds who wants what you're building, watches every competitor, and re-tests the roadmap against what she learned.

when something is the founder's call, she texts or phones you, gets the answer, and keeps moving. you come back to finished work and next moves, the way it works with a cofounder.

01 · brain

she knows your startup. and you.

one brain holds every person, number, and decision. it writes Command: today's move, and what she already started.

how Cortex works

Cortex is the brain behind her: a three-layer memory (working memory, user profile, knowledge graph) that maps everything connected to your startup and to you as a person. people, projects, metrics, events, ideas, places, preferences, habits.

02 · phone

she has a phone.

save her number (+1 (415) 915-2731) like any contact. she wakes you up, briefs you, and makes your calls.

she texts and calls you.

tell her "call me when…" once. the moment that email lands, your phone rings.

she calls people for you.

tell her who and why, then read what happened. you were never on the call.

on planless, their ai picks up.

the two AIs sort it out. you both just read the summary.

03 · meetings

she's in the meeting with you.

bring her into any call. she answers out loud, jumps in when it helps, and writes up what was decided.

go without you.

send her to the one you can't make. the memo comes back with what's on you.

she holds the line.

she stays on your brief. the roadmap and the numbers stay where you left them.

04 · email

your inbox, and everyone in it.

a full email client, built in. she knows everyone in it, so every thread arrives with its history attached.

she drafts replies in your voice and clears the rest. Command shows only what needs a founder.

05 · calendar

a calendar that knows what matters.

she runs your calendar on her own: blocks focus time, declines what doesn't fit, and sends your booking link.

you never touch it.

say "protect my mornings" and it's on the calendar.

she knows why.

she guards the block before your demo. she knows what it's worth.

06 · research

she does the homework.

while you build, she watches your market and who's tried this before. when something changes, a cited brief lands in Command.

companies · markets · communities. sources linked. Cortex learns. Command updates.

07 · thinking

she pushes back.

when the evidence changes, she changes the plan, names the risk, and drops the next move in Command, unasked. she won't agree just to be agreeable.

north star: one outcome. today: next move. this week: proof gate. cofounder: owns a lane.

built for founders, as one, since day one

her hands are real: inbox, spreadsheets, docs, forms, booking page. all native, all run by your voice.

voice

run the company by talking. one sentence reaches everything below. Say: "model burn, then reply to Sarah".

email

your inbox, built in. she knows everyone in it and gives you about seven hours back a week. Say: "reply to Sarah, cc the investor".

sheets

a real spreadsheet engine, five hundred functions deep. she builds your model and keeps it live. Say: "model burn and runway to December".

docs

your real numbers are already in the doc. you never start from blank. Say: "draft this month's investor update".

forms

she builds the form, gathers the answers, and routes them back into the work. Say: "spin up a user-research form".

booking

one link books the meeting. she briefs you before it and drafts the follow-up after. Say: "send them my booking link".

Neptyn 1.0: the model behind her

she runs on Neptyn 1.0, built by Brainsless Research Lab (https://brainsless.com). trained on founder and operator thinking patterns, with a three-layer memory system: working memory, user profile, and a temporal knowledge graph that grows with every conversation.

research: "A Measured Decomposition of the Trillion-Parameter Serving Step" (BRL-2026-11), serving Kimi-K2.6 at 511.6 tokens per second single-stream on four B200 GPUs, lossless. part of the lab's attention series: "Attention Has A Type", "Attention Pays Its Bill", and "Attention Finds Its Keys".

we can't read your data

Zero-knowledge · AES-256-GCM. how the vault works

encrypted in your browser: AES-256-GCM in the browser. the key never touches our servers.

zero-knowledge architecture: we have no way to read your tasks, docs, or emails. the math forbids it.

inference only: inference runs on your encrypted context in-session. nothing raw is stored after.
