    Stop being the bottleneck in your own company.

    Iwo Szapar’s AI Second Brain is a repository you install once. It loads your metrics, decision history, and writing voice into Claude, so /investor-update returns a send-ready draft with real numbers in your tone instead of a list of questions.

    Based on your Q1 financials (pulled from Stripe + Supabase), ARR grew 34% to $2.1M. Churn dropped to 3.2% after the onboarding changes you shipped in February. I've drafted 12 slides using your board template with the narrative structure your board liked last quarter.

    Straight answers

    What founders ask before buying.

    I'm not technical. This looks like a developer tool.
    69% of buyers are non-technical and 85% buy for themselves. Kickstart is a guided install: the AI agent configures the system from your questionnaire. You never write code.
    I already pay for ChatGPT and Claude. Why would this be different?
    Same model, different starting point. The before/after section above is the whole argument: identical prompt, one has your context loaded, the other asks you five questions. The product is the context, not the model.
    I don't have time to set this up.
    Richard Wilson tried building it himself and this saved him 3 to 4 months. Kickstart is configured for you from a questionnaire. Done-With-You means it is installed with you on a call. The setup cost is the thing you are buying your way out of.
    Another subscription I'll churn out of.
    One-time price. The repo, the database, and everything the system learns are yours. Cancel nothing, keep everything.
    My company data in someone else's cloud is a non-starter.
    Default is a local database on your laptop. Optional cloud is your own Supabase account. The vendor never holds your knowledge data. Your judgment stays in infrastructure you own.
    Will it actually sound like me in front of investors?
    Setup encodes your voice and standards as validation rubrics. A hook checks every outbound draft against them before it is done, and another blocks sends that quote no real metrics. The guardrail is shown above, not claimed.
    I already purchased Second Brain. What's new in 2.0 and do I need to upgrade?
    2.0 is a structural rebuild. The AI agent reads your questionnaire and configures everything for you (no manual setup). The system now prunes stale knowledge automatically so it sharpens over time, and health monitoring flags when things drift before you notice. Your existing setup is a valid foundation and transfers directly. Email hello@iwoszapar.com to discuss upgrade options.
    I'm not technical. Can I use this?
    54% of our clients had never opened a terminal before. 58% are in non-technical roles. The setup is guided step-by-step, and the Kickstart option means our AI configures everything from your questionnaire answers. You don't need to write code.
    How is this different from ChatGPT Memory or Projects?
    ChatGPT Memory stores random facts. This engineers your entire work context β€” voice patterns, client history, decision frameworks, connected tools. It's the difference between AI that 'remembers your name' and AI that 'knows your business and runs your operations.'
    What if AI models change? Will my system break?
    Your context, skills, and workflows live in files and a database you control. Codex, Claude Code, ChatGPT Work, Claude, Gemini, and local agents can use that core through their own setup. Client-specific hooks and plugins need their matching adapter.
    What do I need to get started?
    A computer and an AI surface you want to use. Claude Code, Codex, and local agents run the full workspace setup. Chat and desktop surfaces use the connections and workflows available to them. The guided process configures the right starting point.
    What's the difference between DIY, Kickstart, and Done-With-You?
    DIY ($197): Full repo, self-serve setup, no support. MemoryOS available separately. Kickstart ($597): AI agent configures your system from a questionnaire, plus async support and first year of MemoryOS Pro. Done-With-You ($2,497): 2-hour onboarding call, full infrastructure deployment, and monthly updates.
    Is there a money-back guarantee?
    Yes. 7-day unconditional money-back guarantee on all packages. If it doesn't work for you, email us and we refund β€” no questions asked.
    Wherever you are

    Your existing tools. No extra layer.

    Memory added to the AI you already run the company through: brief on your phone at 8:00, deep work on desktop at 9.

    Your AI, as you already use it

    Claude Code and Codex, desktop app or CLI, and on your phone through the apps already on it. Nothing new to learn, no new tab to live in.

    No new monthly bill

    It runs on the AI plan you already pay for. The system itself is a one-time purchase. Nobody wants subscription #14.

    No lock-in, ever

    Plain files and a local database on your machine. Stop paying nothing, lose nothing: it keeps working forever, and you can walk away with everything.

    Battle-tested

    100+ professionals run it in daily work, most of them non-technical. Six months of the creator’s own client work ships through it.

    Point-tool competitors are another login, another subscription, another silo. This is neither another, nor either.
    After you buy

    Made yours, while you sleep.

    Nobody gets a template. The questionnaire feeds a setup agent that researches your world and configures a system that is yours alone.

    01
    15 minutes of questions

    Your clients, your tools, your writing samples, the shape of your week. Plain English, no technical questions.

    02
    An agent researches and builds yours

    Configured uniquely for you on the current frontier models. No two repos come out alike. It runs overnight: Iwo does not need to be awake for your brain to get built.

    03
    Delivered in 24–48 hours

    Folders named after your real clients, your voice rules, your commands. You open it and it already knows you.
