Changelog
What changed, and when
Every change that affects what the software does, what it costs, who processes your data or what this site claims gets a dated line here, including the faults found after release.
Version 4.3.0 is current. Nothing before version 1.0.0 exists.
Releases
Version 4.3.0, company sign in, connections to the systems you already use, watched scenarios, and five more languages
On Boardroom and Enterprise a company can prove its domain with a DNS record and connect its identity provider over OpenID Connect, so its people sign in there and can be required to. The provider can add, change and switch off people over SCIM, and somebody switched off there is signed out here at once. From Operator up, a twin connects to Stripe, HubSpot, QuickBooks, Xero or a spreadsheet link and pulls revenue, costs, cash and customers month by month once a day, with every key sealed before it is stored. A scenario can be watched, so it runs again when new actuals arrive or every week, and a changed answer lands on the record and in your notifications. A bell in the top bar lists what needs you: mentions, replies, alerts, proposals, decisions and connections that fail. Every row of the ledger carries its own discussion. Files and questions in Spanish, French, German, Portuguese and Italian are read, numbers and months included, and with a language model configured the answer comes back in the language of the question. Every page now tells the browser which scripts it may run. The operator settings take the QuickBooks and Xero app keys and never print a saved secret back.
Version 4.2.0, what would it take, two step sign in, and working on a twin together
What would it take is a new screen under Decide. Name where you want to be, a margin, a profit, cash at the end, revenue or customers, and each lever is walked across its range on the same seeds as the year you are on. The smallest move that gets there comes first, with how often the year makes it, what else it changes and the numbers it rests on, and one click makes it a scenario. A goal asked in Ask goes straight there. Two step sign in works with any authenticator app, with ten recovery codes, and the account screen now lists every place you are signed in with a button that ends the others. The operator can require two step sign in for everybody and sign people out after a set idle time. Seats given to colleagues now send them an email, and a seat given before the person had an account is theirs the moment they make one; until now it waited for ever. Decisions, analyses and runs each carry a discussion, and an @ before a name sends that person a note. The ledger, a run, the register and the record of changes download as spreadsheets. A new twin opens with a list of the first six things worth doing. On a phone the decision register reads as cards. A review date no longer shows as the day before for anybody west of London. Saving the operator settings no longer switches off the free plan. The site now publishes a security.txt that says where to report a fault.
Version 4.1.0, your data in one download, closing an account on your say, and a site ready for strangers
The account screen now has Download everything: one file with your profile and every twin you own. Each uploaded file downloads from The record as you gave it. Close your account there too: in thirty days, with one button to keep it until then, or everything at once. Closing cancels the plan at the same moment. Cached language model replies now go with their twin and never outlive thirty days. Signing up offers Free straight into the application, asks you to agree to the terms and the privacy policy, and sends a welcome that says where to start. The site sends the headers a security review looks for, gives away nothing about the software underneath, and keeps the list of accounts private. A link to the site shows a proper card wherever it is pasted, and the site has a new icon drawn from the mark. The page loader is in the page from the first frame, follows the page's real progress and lifts as the headline arrives. A hairline shows the next page on its way, and the application opens on its own shape. The privacy policy, the terms and the pricing questions now describe exactly what the product does when a subscription lapses: it moves to the free plan and nothing is deleted.
Version 4.0.0, a knowledge engine behind Ask, a network that checks itself, and a site built around one moving picture
Ask now answers from everything the twin knows: thirty three concepts in eight families, from margin, cash and churn to suppliers, seasonality and regulation. Every answer lists each step it took, reading, looking up, computing, comparing and checking, and cites the file, record, node, run or calculation behind each figure. Each answer says how much of it stands on your own files and which uploads would sharpen it, with where each one goes. A question that is a decision in disguise goes to a full analysis, which now reads the record as well as the model and states its headline in your currency. Files are read more closely: numbers written as words, the share of revenue under contract, on time delivery and lead times. The share of cost of goods going to suppliers was overstated, and is fixed. The network holds back part of the record to test itself before it is trusted, trains with a better method, and you can watch it think through a question node by node. A company that has uploaded nothing yet is told what is missing and which file brings it, instead of arithmetic on industry defaults. What to upload now shows how ready each kind of question is. On this site one picture moves: the twin, drawn as a turning globe of connections. Statements light word by word as you read, and a line under each section number fills with the scroll. The tilt, the glow and the lens effects are gone, and everything holds still for anybody who asks for less motion.
Version 3.9.1, quieter buttons
The circle that followed the pointer around the site is gone, buttons no longer drift toward the pointer, and the light no longer sweeps across the main button. Under the pointer a button now only changes colour.
Version 3.9.0, every figure on the overview opens
The four figures at the top of the overview open into their next twelve months: where they are now, where they are heading, the likely range, a chart with its band, and the numbers in the ledger that move each one with where every number came from. From there, ask what drives it, open exactly those numbers in the ledger, or stress test the company. The rest of the overview opens too: the counts go to their screens, the origin chips open the ledger filtered to that origin, each missing file goes straight to its upload, and each class in the ecosystem opens its agents.
Version 3.8.0, the knowledge graph as a globe, and company details you can change
The knowledge graph is a globe with the company at its core and everything else on the surface, each kind in its own band. It turns slowly on its own; drag it, swipe it or use the arrow keys, and pick a kind to bring it to the front with every name in it shown. Pointing at anything lights what it touches and holds the turn. The account screen now leads with the company the twin models: change its name, its industry or its currency. A new industry moves every figure still on an industry default and rebuilds the twin, while anything from your files or set by hand stays where it is. Only the owner can make these changes. The page index on wide screens takes its colours from whatever is behind each line, so the current section reads clearly in both themes.
Version 3.7.0, twenty industries, a graph you can search and open, footer menus, a sign in page of our own, and every screen checked on a phone
Eight new industry profiles: energy and utilities, agriculture and food production, real estate and property, media and publishing, telecoms and connectivity, wholesale and distribution, life sciences and medical devices, and marketplaces and platforms. Each carries its own starting figures, how money moves, how such companies get into trouble, what they have to decide, their year, and where the simulator models them badly. The knowledge graph can be searched by name and narrowed by kind; pointing at anything lights its connections, and clicking it opens what it touches, what the record says about it and which files name it, with its agent one click away. The footer is six menus instead of a long list. Signing in, resetting a password and signing out happen on a page of this site, and eight wrong attempts from one address pause signing in there for fifteen minutes. Every page of the site and every screen of the application now passes a check at phone width: nothing runs off the edge, no text is under eleven pixels, every control is big enough for a thumb, and fields no longer zoom the page when tapped. The contact and account forms, which a background animation had been drawing over, are fixed.
Version 3.6.0, agents you can open and edit, a graph drawn as a network, and thirty one ready made questions
Every agent opens into a drawer with its objectives, constraints, what it can see, its personality, its relationships and its history, and an Edit button changes any of it; an edit is marked as set by hand and written to the record. The knowledge graph is drawn as a network in layers, with signals travelling along the heaviest connections. Sixteen new ready made scenarios cover annual prepayment, bundling, working capital, a four day week, outsourcing, automation, rates, inflation, a key person, price matching, currency, retention spend, leaving a segment, pay, credit and resellers. Settings show their themes across the full width, the footer is rebuilt, prices carry their currency, and the security page now leads with what happens to your files.
Version 3.5.0, the same decision on other seeds, and the file that would tighten an answer
A single decision is run again on three sets of seeds and drawn on one axis with a verdict: firm, fair, loose or chance. Under every answer, the defaults it leans on are grouped by the one file that would replace them, with the coverage the answer would reach and a button that opens the upload. The book's exchange rates can be fetched once a day from the European Central Bank. Every analysis carries a rail of its sections, and every sentence on this site was checked for clarity.
Version 3.4.0, one currency for the book, a receipt for every upload, and answers that leave with you
The portfolio converts every company into one currency and names any it cannot. Every rebuild hands each file a receipt: which numbers stand on it and which changed. An analysis exports as an evidence bundle with every citation, and Present mode exports its deck as a page that prints a slide per sheet. Alert mail arrives as a framed message with a link straight to the twin.
Version 3.3.0, questions taken apart, an answer that argues against itself, and Present mode
A question with several questions in it is answered part by part, then as a whole. Every answer looks for evidence in your own files against the numbers it stands on, and lists the same question asked before with how much has changed since. Any analysis or run becomes a deck with Present. The site and the application gained living backgrounds and motion throughout, all of which stops for anybody who asks for less motion.
Version 3.2.0, the portfolio, alerts, four eyes, and a model that marks its own homework
The portfolio holds every company in one book, ranks the ones that need a person today and puts one question to all of them. Alerts watch each twin with eight rules and thresholds you set, by email and in a digest. Every change to the ledger can need a second signature, with its impact computed before anybody signs. Closed decisions and drifting actuals now move the confidence of every new answer.
Version 3.1.0, the governance layer
A decision register that records the band the model gave and what happened, and scores the model across every closed decision. A monitor that lays actuals on the forecast and calls drift. A stress battery of fourteen shocks with one resilience score. Four roles, snapshots with a diff between any two, a record of everything that happens on a twin, and keys and signed hooks for your own systems.
Version 3.0.0, every answer shows its working
Under every conclusion: how much of it stands on your own files, a picture of the path from your files to the answer, the reasoning step by step, and the lines it quoted. The upload guide became a card for every kind of file with where it goes and what it unlocks. Forty three settings, twenty six themes and a site rebuilt from the type up.
Version 2.10.0, the application takes the whole window
The application opens at full width and full height, whatever it sits inside. Every drawing on this site moved onto one palette, where colour means something: the thing being measured, a guessed number, or a threshold crossed.
Version 2.9.0, no two pages share a picture
Every drawing on this site is generated for the page it is on, and a check fails the build if any picture appears twice. Headlines, drawings and figures move with the scroll, and all of it stops under reduced motion.
Version 2.8.0, a missing file found, and a typeface
A fault that stopped the application starting on a live site was traced to a file that was never loaded, and a check now catches that class of fault for good. The site is set in its own typefaces, served from our own servers, and a phone layout fault on every page was fixed.
Version 2.7.0, an application that opens whether or not the network answers
The application now opens with everything it needs already on the page, and says in one line if changes cannot be saved, rather than showing a dead screen. Every route is tested with real parameters, and the home page was rewritten in shorter sentences.
Version 2.6.0, twenty two more levers
The engine went from thirty five levers to fifty seven: payment terms, stock cover, prepayment, bundling, price matching, onboarding and support spend, automation, outsourcing, capacity, a four day week, office policy, bonuses, training, leaving a segment, the exchange rate, inflation, credit and losing a key person. A lever left at zero is now proved to leave the company exactly as it was.
Version 2.5.1, two levers at once, timing, and the bad case taken apart
Two levers can be swept against each other and read as a surface, with a verdict on whether they help or fight each other. Every analysis prices a month of delay and takes the worst tenth of the runs apart. The assumption ledger lines every figure up by column.
Version 2.4.0, interaction, and an answer that remembers
A question naming two decisions runs four ways and reports the interaction between them. An answer that contradicts an earlier one on the same decision says so, with the date. Eighteen themes that look different from each other.
Version 2.3.0, the breaking point
Every analysis works out how far each number it depends on would have to move before the recommendation reverses. Building it found and fixed a fault that had been answering every what if at the wrong value. Sixteen themes and seventeen accents, every colour pair measured.
Version 2.2.0, settings and a command palette
Twenty seven settings saved to your account, a command palette on Control K, a dark theme across this site, and a contrast audit of the application that found and fixed nine faults.
Version 2.1.0, the analysis layer
An analysis layer that takes a complex question apart, plans the investigations that would settle it and says how confident it is and why. Six more classes of actor, twelve industry profiles, and fixes for every fault the first live release found.
Version 2.0.0, the network and the free tier
The company is now called Counterfirm. A neural network trained on your own twin, a Why chain on every number that ends at a quoted line in one of your files, a readiness score that tells you which document to send next, a free tier that takes real files, and a rebuilt interface.
Version 1.0.0, the first release
The simulation engine, agent generation, the assumption ledger, ready made scenarios, sweeps, side by side comparison, the decision brief, sensitivity, Ask, the worked example and this website.
There are no entries before version 1.0.0, and there is no history hidden behind a link. A changelog that begins with a long list of invented past releases is a common way to look established, and this one does not do it.
What will get an entry here
So that this page stays worth checking, the rule is written down rather than left to judgement.
- Any change to what the software computes, including a change to a default in the ledger.
- Any new capability, and any capability moving between built, partly built and not built on the status page.
- Any price change, with the date it takes effect.
- Any new or replaced sub-processor, at least thirty days before it starts processing.
- Any material change to the privacy policy, the terms or the data processing addendum.
- A penetration test, a backtest against real outcomes, or any certification, with the findings rather than just the fact of it.
- Anything that was wrong on this website and has been corrected.
That last one matters most. A site that quietly fixes its claims is worse than one that never made them.
What is coming, without dates
The roadmap page lists what is being considered next, grouped into near, later and probably not, with nothing on it presented as a promise.
