Eidos

Your thesis, your plans, and why you said no, in one place.

One page for the thesis, each idea, each plan, each round, and each call you made, with the reasons. Draw how they connect and see which pages still have gaps. The ideas you killed stay, so the next person who suggests one finds out why.

A canvas for a fictional restaurant-software startup: the thesis and runway, three ideas (active, parked, killed), a plan, and the pre-seed round, joined by labelled arrows, with a sticky note about investors who ask about the killed idea.
What the round pays for, what each plan proves, and the killed idea, linked to the decision that killed it.

Sound familiar?

The deck says one thing, the plan another, and nobody remembers why.

  1. The deck drifted

    The price changed and the team grew, but the deck tells last quarter’s story. Every investor meeting costs a weekend of slides.

  2. The reasons are gone

    You killed an idea in March. In September an advisor pitches it back, and the reasons are lost in a chat thread.

  3. Every update starts from zero

    The monthly investor update means digging through emails and spreadsheets, because the numbers live in five places.

How it fits

Every idea, plan, round, and call gets a page.

Start from the Venture framework: four pages say what the business is, and everything you weigh gets a page of its own. Ideas, plans, and rounds carry a decide-by date, the day you owe yourself a call.

The Business
Four pages: the thesis, the market, how it makes money, and the runway. Everything else is read against them.
Ideas
A spark grows into a case: the problem, who pays, the numbers, and what would kill it. A killed idea stays, marked Killed.
Plans
By line of business: the goal, the moves, the milestones, and what would stop it early.
Investments
A round you raise or a cheque you write: the amount, the terms, and the expected return.
Decisions
The situation, the options, what you did, and what would reopen it.
Pitch, Roadmap, Team
One page each: the business in thirty seconds, the next twelve months, and the empty seats.
The Ideas of a fictional startup as a table: each with a summary, whether it is a spark or a full case, its status (Killed, Parked, Active, or Draft), its tags, and its decide-by date.

What you will use most

The tools that keep the story straight.

  • Blueprints

    Gaps, flagged

    The health check lists every page missing a section its template asks for, like a plan with no What Would Stop It.

  • Canvas

    The bet on one page

    Lay out the thesis, ideas, plans, and round as cards that open their pages, with arrows that say what pays for what.

  • Backlog

    The work, pointed at the plan

    The investor update, the supplier sheet, the second angel: tasks on a board, each pointing at the page it serves.

  • Comments

    Notes from your advisor

    A cofounder or advisor leaves a note on the exact section, and you close it once it’s answered.

  • AI Agent

    A sparring partner, only if you want one

    Connect your own Claude Code or Codex and ask. It can question your thesis point by point, or draft the month’s update from your pages for you to edit.

Ideas

Write down what would kill it, before you love it

An idea’s page asks for the case as checkable claims, your assumptions, what’s still open, and the evidence that would end it. Skip a section and the health check lists the page until it’s back.

An idea page for supplier price alerts: the case as three numbered claims, what would kill it, what the idea is not, where it fits the thesis, and a dated note.

Decisions

Keep the record of the no

Each call gets a page: the situation, your options, what you did, what it changed, and what would reopen it. When an investor asks about the idea you dropped, send the page.

  • Killed ideas stay in the table, marked Killed.
  • Any page exports to PDF from its menu.
  • Rename a page and every link follows.
A decision page titled Stop the Catering Marketplace: the situation, three options including doing nothing, what was done and by whom, what it changed, and what would reopen it.
