System of record for decisions
Make important decisions you can explain, defend, and learn from.
EONVANT structures your options, evaluates evidence, challenges assumptions, and remembers what happened next.

Should Meridian Advisory enter Market A or Market B within the next 12 months?
Sequenced entry — establish in Market A first, prepare Market B for month 9.
Primary risk
Licensing timelines are the largest source of slippage.
Next action
Commission a written licensing timeline from local counsel.

The problem
Important decisions leave almost no trace.
- 01
Decisions disappear.
Decisions get made in chat logs, calls and spreadsheets, then disappear.
- 02
Evidence gets blurred.
Evidence, assumptions and opinion blur into one confident-sounding paragraph.
- 03
Outcomes are forgotten.
Nobody records what actually happened, so the same mistake is available again.
What EONVANT is
A place where your important decisions live.
You bring a decision that matters. EONVANT turns it into a record: the question, the options, the criteria and their weights, the evidence with its labels, the case against, the call you made, and the date you will check it.
Six months later that record is still there — with what happened next attached to it. That is the part no chat window gives you.
How it works
The loop, at a high level.
- 1Frame
State the real question, the constraints, and what is out of scope.
- 2Research
Gather what is known, from sources you can see and check.
- 3Verify
Label every claim: verified, assumption, estimate, prediction, opinion.
- 4Compare
Score options against criteria you weighted, with reasons for the weights.
- 5Challenge
Argue against the recommendation before you commit to it.
- 6Decide
Record the call, the confidence range, and what would change it.
- 7Track
Come back at the review date and write down what actually happened.
- 8Learn
Record the outcome and the lessons, kept with the decision for future reference.
The artifact
The decision record
Conclusion first, then the reasoning underneath it. You should never have to read to the bottom to find out what was recommended.
- 01
Executive summary
Recommendation, confidence range, why, primary risk, next action.
- 02
Labelled evidence
Every claim carries its type, its source and how recent it is.
- 03
An independent challenge
The strongest case against the conclusion, written to be uncomfortable.
- 04
A timeline with a review date
Framed, revised, decided, review due, outcome recorded.
Signature component
What would change this recommendation?
A recommendation without conditions is a guess wearing a suit. Every EONVANT record names what would flip it, and which option each condition favours.
Licensing in Market A is confirmed to take longer than 4 months end to end.
→ Market B only
An anchor client in Market B commits to a retainer of 12 months or more.
→ Market B only
Two senior hires are secured before month 3 rather than after.
→ Simultaneous entry (A + B)
Cash runway drops below 9 months for any reason.
→ Defer 6 months

Trust and evidence
Nothing is allowed to sound more certain than it is.
Claims are labelled by type. Confidence is a range. Missing information is stated rather than filled in.
Confidence as a range
Midpoint 68%
Missing data is visible
Unresolved conflicts and open unknowns stay on the record with their own labels, and they lower the completeness readout.
Scope
Decision support, not regulated advice. EONVANT does not act on your behalf and does not claim authority it has not earned.
The category
Temporal decision intelligence
A decision is not a moment. It runs from what already happened, through the call you make, to what it turned into — and back into how you decide next time.
- Past
What has already happened
Prior decisions, recorded outcomes, and your calibration to date.
- Present
What is known now
Evidence gathered, labelled and dated.
- Future
What is plausible
Ranges and scenarios, not single-number forecasts.
- Decision
The call
Recommendation, confidence range, and what would change it.
- Outcome
What happened
Predicted versus actual, written by you.
- Learning
What changed in you
Calibration updates and carries into the next decision.
Outcomes and learning
The review is the product.
Anything can produce an answer. Very little tells you whether its last answer was any good.
Predicted versus actual
The prediction is on the record before the outcome exists, so the comparison is honest.
Calibration over time
Where you are consistently over- or under-confident, by decision type.
Kept with the decision
Outcomes and lessons are recorded and preserved as memory for future decisions. They are not applied automatically.
Where it fits
Any decision worth being able to defend later.
- Work
“Should we rebuild the platform now or extend it for two more quarters?”
- Business
“Which of two markets should a 20-person firm enter first?”
- Career
“Take the larger role at a weaker company, or stay and specialise?”
- Major purchases
“Buy now at this rate, or wait nine months and re-check?”
- Strategy
“Concentrate on one segment, or hold two and lose focus?”
EONVANT TWIN
An intelligence model that learns how you decide.
Planned direction, not a live feature. Over time, EONVANT is intended to learn your goals, priorities, constraints, risk preferences and decision history — while keeping every inference visible, editable and under your control.
You stay in control.
Illustrative preference model
- Risk tolerance
- Moderate — accepts reversible downside
- Default horizon
- 12 months
- Will not trade away
- Delivery quality in the core business
- Known bias
- Under-weights regulatory timelines
The Twin never acts on its own and never decides for you.
For teams and organisations
Build an institutional memory for decisions.
Planned direction, not available yet. Shared team workspaces are intended to keep important decisions, evidence, assumptions, revisions and outcomes in one shared record your organization can learn from.
- Shared decision history
Every team member sees the same record, not a chain of forwarded messages.
- Versioning
Changes to weights, evidence and conclusions are preserved with their reasons.
- Institutional knowledge
Assumptions and outcomes stay attached to the decision they belong to.
- Review workflows
Due dates and review reminders are surfaced, not buried.
- Auditability
A clear trail of who changed what, and why the recommendation shifted.

Questions
Straight answers.
Is this a chatbot?
No. There is no conversation to scroll back through. The output is a decision record: a structured document with a conclusion, labelled evidence, a challenge, and a review date.
What does it actually do today?
You can create an account and keep private decision records that persist. Live today: framing the question, options, criteria and weights; evidence and research gathered only when you explicitly ask for it; comparison, adversarial challenge and sensitivity testing; a decide gate that will not manufacture a recommendation without a decision-grade leader; the act, track and learn stages after a decision is recorded; and readable JSON export of your own records from Settings. Billing is not enabled, and the Twin and team workspaces are not built yet.
Who owns the data?
You do. Decisions, evidence and outcomes are private to your account, exportable as JSON, and permanently deletable from Settings. AI and research run only when you explicitly trigger them.
Are you tied to one AI model?
No. Model independence is a design constraint. Providers change; the decision record and the graphs behind it are the durable asset.
Where does confidence come from?
From the balance of verified evidence against assumptions, the unresolved questions, and the sensitivity of the ranking to the weights. It is reported as a range, never as a single false-precision number.
Is this professional advice?
No. EONVANT is decision support. It is not legal, financial, medical or otherwise regulated advice, and it does not act on your behalf.
What happens if I ignore the review?
The record stays open and is marked as such. The learning loop only works if outcomes get written down, so reviews are surfaced rather than buried.
