The working surface for solo founders.
A calm home base for people running more than one thing at a time. Foundry treats ideas, opportunities, decisions, commitments, and projects as different kinds of work and handles each one the way it actually needs to be handled.
Three things waiting for you.

"Agents that score their own output"
The problem
Most founder tools are task managers in disguise.
Notes apps turn into graveyards. Task apps flatten strategy into checkboxes. Note-linking tools record everything and tell you nothing. AI copilots forget the conversation you had last week.
None of them tell the difference between a half-formed idea, a real opportunity, a live commitment, and a decision you already made. You end up being the difference. That is the cost most founders pay every single day.
How the week actually runs
Four moves. Every week. Forever.
01
Write it down
Twelve typed notes keep a shower thought and a pricing plan from landing in the same pile. Ideas come in raw and move along a path instead of getting lost in a giant note.
02
Weigh in
A quick pass for the obvious calls, a longer 16-point look for anything worth more thought. You end up with a reason behind every call, not a mood.
03
Decide
Log the call, the alternatives, the assumptions, and the condition that would prove you wrong. A reminder brings it back for a verdict later, so nothing important quietly rots.
04
Follow through
Projects carry a health read, commitments have due dates, and the weekly review brings unfinished intentions into next week. A setup that says no with you, not against you.
Inside
The screens you will actually live in.
Each one has a point of view. None of them are optional. Together they are what takes Foundry past a prettier notes app.
Morning dashboard
Your first screen every morning. Overdue decisions, commitments due today, old captures, and the intentions you set on Monday. One view, in order, ready to answer.
Writing pane
A global shortcut and twelve typed notes. Product ideas, feature ideas, opportunities, prompts, reusable patterns, monetisation thoughts, naming scraps. Everything lands where it belongs.
The 16-point weigh-in
Sixteen weighted questions across Strategic, Market, Feasibility, and Alignment. Ten possible outcomes, from Build Now to Kill. You see why, not just what.
Decision log
Context, reasoning, alternatives, risks, and the condition that would prove you wrong, all in one place. Revisit dates bring the call back in front of you when it matters.
Guardrails
Project caps, energy labels, an open-loop counter, and a single Focus project for your main bet. A setup that protects your attention whether you ask it to or not.
Weekly review
A two to fifteen minute routine. Reflect, clear the queue, note wins and lessons, set next week. Unfinished intentions carry into Monday so the week starts warm, not cold.
The vault
Your working library. Ideas on one side, reusable assets on the other. Prompts, patterns, principles, product truths. A memory for the studio that builds up over time.
Quiet nudges
Eight grounded reminders, never a vague hunch. Overload alerts, old captures, parked ideas worth another look, recurring themes. Each one traces back to a specific thing in your data.
A typical week
What it feels like in practice.
Monday morning
You open the dashboard. Two decisions are up for revisit. One commitment lands today. Three intentions from last week carried over. You set the week in under five minutes.
Wednesday afternoon
Mid-meeting, a new product angle lands in your head. Global shortcut, type it as a Product Idea, one line, done. It queues up for the Friday pass.
Friday weigh-in
Six captures are in the queue. Quick pass kills two, parks one. You run the full 16-point check on the strongest. It comes back Explore Actively, with the reasoning attached.
Sunday evening
A fifteen-minute weekly review. Reflect, tidy up, note wins and lessons, set three intentions for next week. Foundry carries what you did not finish into Monday.

Start 14-day free trialQuestions worth answering
Is this another task manager?
No, and that is kind of the point. Foundry separates ideas, opportunities, decisions, commitments, and projects because each one needs handling differently. A task list treats them all the same and flattens the interesting bits out.
How long does it take to get value?
Day one is already useful as a writing pane and decision log. The bigger payoff shows up around month three, when the vault, decision history, and weekly snapshots start reading like a memory of the studio itself.
Do I need to be technical?
No. If you can write down a decision and come back to it, you can use Foundry. The app does the structure for you.
What about mobile?
A native iPad and iOS app is next, built on the same database. You will be able to capture, weigh in, and review from anywhere.
What counts as AI use?
Each time Foundry calls Claude on your behalf, it counts against that feature's monthly allowance. Pro gives you 100 weigh-ins, 50 decision reviews, 10 weekly summaries, and 30 founder briefings a month. Allowances reset on the 1st. Free gets 5 AI uses a month so you can try the feel.
Monthly or annual?
Pro is $25 a month. If you prefer to pay once a year, $250 annual saves you $50. Same Pro, either way. You get a 14-day free trial before anything renews.
