The World is Horizontal.
Your Focus Must Be Vertical.
Stop reacting to the sprawling noise of Slack, email, and "urgent" pings.
Bunker Stack provides the shielded environment to force-rank your priorities into a single, vertical line of execution.
Why "Bunker Stack"?
The World Spreads You Thin
Modern work is "Horizontal." It's a flat, endless plain of incoming missiles—notifications, shallow tasks, and infinite tabs. It forces you to multitask, which is just failing at several things simultaneously.
The Bunker Forces You Deep
The Bunker walls off the horizontal noise. Inside, we build The Stack. You can't do three things at once. You can only do one thing on top of another. We force you to stack your Top 3 priorities vertically. Tackle the top one. Ignore the rest.
Are you stuck in the "Horizontal Trap"?
You touch 50 tasks a day but finish zero. Your attention is spread so wide it has no impact. You are busy, but you are not building.
Your to-do list has 20 items, all marked "High Priority." When everything is important, nothing has height. You need a stack, not a list.
Without vertical focus, you drift horizontally from idea to idea. Great plans become noise in the endless plain.
Horizontal is the default. Vertical is the weapon.
Bunker Stack exists to break the horizontal trap: pings → sprawl → infinite lists → zero execution.
OKR — Your North Star
Set 2-3 core Objectives per month or quarter, paired with measurable Key Results. Every Weekly Top 3 must link to an OKR—ensuring each week's effort drives long-term goals.
The Vertical Toolkit
The Vertical Stack (Force-Ranked Priorities)
Stack your priorities vertically — the top one is the only one that matters. Only 3 slots allowed. To add a new mission, you must finish one or kill one. No horizontal expansion allowed.
Waiting For (External brain)
Stop tracking other people’s obligations in your head. Let the system chase updates.
The Perimeter Wall (Defense Zone)
Everything that tries to attack your Stack from the side goes here. Write it down to acknowledge it, then brutally ignore it until the Stack is clear.
The Brutal Coach (AI Chief of Staff)
No praise. Just one question: “Does this help your Top 3?”

Field Reports
"As a solo founder, my biggest enemy isn't competitors — it's Shiny Object Syndrome. The No-List is my savior. I used to get distracted by new ideas for days; now I throw them into the defense zone and my brain goes quiet."
"Every week used to be 'firefighting week.' Jira tickets, PR reviews, cross-team meetings… Bunker Stack forced me to be the bad guy. When I had to kick the 4th task out of my Stack, I realized how many impossible promises I used to make."
"OKRs used to be slogans in a Google Sheet — written at the start of the quarter, revisited at the end. The most brutal feature is 'OKR forced linking.' If my weekly task can't map to a Q1 goal, the system calls me out."
"As an hourly consultant, I used to fall into the 'fake work' trap — answering emails, organizing files all day. Bunker Stack showed me the truth about my time. When I threw low-value tasks into the No-List, I realized I only have 3 real billable hours per day."
Frequently Asked Questions
Vertical Stack is a prioritization method where you can only have 3 active priorities at a time. Unlike horizontal to-do lists that sprawl endlessly, a vertical stack forces you to complete or remove one item before adding another. The top of the stack is the only thing that exists.
Regular to-do lists grow horizontally — you add items without limits, everything feels equally urgent, and nothing gets done. Bunker Stack enforces vertical constraints: only 3 priorities per week, explicit "No-List" for rejected tasks, and an AI coach that challenges every addition. It's not about doing more, it's about doing less but finishing.
Every Weekly Top 3 must link to an OKR (Objective and Key Result). This ensures your weekly execution directly drives quarterly goals. If a task doesn't connect to any OKR, the system asks: "What are you even doing this week?" — forcing strategic alignment at every level.
Yes, Bunker Stack is free to start. You can use the core features — Top 3, Waiting For, No-List, and basic OKR tracking — without paying. Premium features like AI coaching and advanced analytics may be added in the future.
