Why I Built KEEP
Structural clarity for multi-account portfolios: Why I traded fragile spreadsheets for a local-first system.
The Illusion of Clarity
Most individual investors have more data than they can process — and less clarity than they admit.
Each brokerage account looks coherent in isolation. Allocation percentages. Sector breakdowns. Performance charts. Clean visual dashboards.
But many investors do not operate from a single account.
They have:
- Individual brokerage
- IRA
- Roth IRA
- Joint account
- HSA
- 529
- Custodial accounts
- Legacy holdings
Each account presents a rational picture. None present the full picture.
I was stitching together a portfolio from half a dozen portals and CSV exports. Each one looked fine in isolation. None showed the full picture — only holdings grouped by account and ticker, disconnected from the structure I intended.
Allocation exists at the household level, across all accounts. Dashboards exist at the account level, zoomed in on a single account. That gap matters.
In other words, strategy should be defined globally. But by default, with scattered accounts, visibility is delivered in pieces.
Fragmentation Allows Drift
When portfolios are split across multiple accounts, clarity fragments.
Each account appears balanced:
Account A — 70% equities, 30% bonds
Account B — 90% equities
Individually, nothing looks extreme. But at the household level:
$$\text{Intended Allocation} \neq \text{Observed Allocation}$$
If the intended structure is 70/30, but the aggregate reality is 82% stocks — structural drift has begun.
The investor believes they are managing a portfolio. In practice, they are managing accounts.
And structural drift compounds in different ways:
- Risk expands unintentionally during stress
- Conviction erodes during strength
- Positions grow larger than originally intended
- You duplicate holdings across accounts and mistake overlap for diversification
You can eventually reconstruct the whole picture — but not from a single login. Decisions are made on partial context.
That is not simply an inconvenience. It is structural degradation of capital discipline.
The Spreadsheet Patch
Serious self-directed investors recognize this problem. So they build master spreadsheets.
They track 3, 5 or maybe 10 accounts. Create custom categories. Stitch together CSV exports. Maintain manual formulas.
Spreadsheets are powerful. Also brittle.
Symbols duplicated across accounts distort totals. Manual updates accumulate friction. Formulas break silently. The mental model lives in column headers. The intent lives in memory.
The system holds numbers. It does not preserve intent.
Judgment Without Memory
A quieter failure mode runs alongside fragmentation.
Investors forget why they bought something.
Years pass. Work gets busy. Outside of work you focus on priorities like family. You hold out of habit. Sometimes sell on noise or re-research positions they already own.
Thesis drift is not dramatic. It is a slow separation between original intent and current reality.
Serious investors already use tools like investment journals, decision memos, review habits, post-mortems. These behaviors predate KEEP by decades. They exist because judgment decays without durable memory.
Why I Built KEEP
I am a software engineer and systems architect by trade. I have invested all my adult life. My career has been spent designing systems meant to operate across years, not days. Architecture matters in these domains.
- In software: poor structure accumulates entropy, context lost becomes bugs, complexity without boundaries degrades performance.
- In investing: poor structure accumulates drift, intent lost becomes habit, complexity without architecture degrades judgment.
Over time, we naturally accumulate multiple accounts. I maintained spreadsheets and manually reconciled exposure. It worked — until the system became too unwieldy to calmly reason about.
I realized I was managing visibility at the account level, but making decisions at the household level. The architecture wasn’t durable.
Even if you work with an advisor, clarity still has to exist on your side of the table.
What I wanted became clear over time:
- A household-level view of all positions
- Sleeves that reflect intent, not just holdings
- A durable record of decisions and reasoning
- Ownership of my own data
- No SaaS lock-in
- No automation replacing judgment
That became KEEP.
The Design Principles
Clarity in capital is not a feature problem. It is a structural problem.
$$C = S + M + O$$
Where:
- \(S\) = Structure (explicit allocation architecture)
- \(M\) = Memory (durable record of decisions and context)
- \(O\) = Ownership (control of data and system)
Without structure, allocation drifts. Without memory, intent erodes. Without ownership, responsibility diffuses.
These are not features. They are constraints.
Why Local-First
Tools that preserve judgment should not demand recurring rent.
Your portfolio history is not “engagement data” for SaaS. It is personal and private capital memory.
Local-first is not aesthetic preference. It is structural alignment.
No subscription. No cloud dependency. No algorithmic nudging. The software should support your decisions — not replace them.
What KEEP Is
KEEP is not a trading app. It does not recommend assets. It does not rebalance automatically. It does not optimize allocations.
It makes structure explicit and preserves intent.
It shows your portfolio as a whole — not as isolated accounts.
It makes drift legible.
It gives serious investors a system that matches how they already think.
Related: Memory, Structure, and Judgment
The framework behind these principles — why context decays, why intent must be bound to capital, and what makes judgment the scarce asset in long-term investing.
Compounding requires discipline. Discipline requires structure. Structure requires architecture.
I built KEEP because I needed a system that respected long arcs. If you manage your investments across multiple accounts and care about preserving judgment over years even decades, you likely feel the same tension.
Tools should make thinking clearer and preserve your judgment.
The behaviors KEEP supports — investment journals, decision logs, custom multi-account trackers — have existed for years among serious self-directed investors. KEEP formalizes them into a durable sovereign system.
