The platform

How the platform is organised
Five stages, from not knowing to having decided.
Every page on this site is filed against one of five stages, and the stage is what tells you where to start. Four of them are built. The fifth is not, and it is marked as such.
Learn
Understand the concept before you model it — definitions, courses and course modules, each on its own page.
644 lessons, modules and defined termsBuild
Put it into a working document — models, forecasts, trackers and guides built to be opened and used.
49 templates, models and guidesDecide
Answer the question on your own numbers — calculators, side-by-side comparisons and worked situations.
85 decision toolsExecute
Do the work — conversions and rate maths inside a job already under way, and a finance team when it needs one.
81 converters, plus professional servicesGrow
The stage after Execute. The content model has carried this term since Phase 2 and nothing occupies it yet.

Get the number, and see what produced it.
166 tools across four families. Each one states what it assumes and which rules it applies, because a number you cannot interrogate is not an answer.

Graded, so you can start where you actually are.
Everything published here carries a level. It is how a glossary term written for someone meeting depreciation for the first time stays distinct from a module written for someone defending a valuation.
Courses
Self-paced and text-based: financial modelling, stock market analysis, options, futures, risk and trading psychology. One is free and open to everyone.
Foundation to working level 507 termsThe glossary
Every term on its own page, defined in plain English and linked to the tools that use it. The largest published surface on the site, and free.
A–Z, searchable Written explanationsGuides and articles
Longer pieces on the questions the tools answer, and on the reasoning behind the answer.

And when it needs a person, not a tool.
The tools and the templates take you a long way. They do not close your books, sit in your diligence call or own your forecast. That work is a service, and it is the same practice that writes everything above.
Monthly Finance Operations
Books closed on a published date, results explained in writing, KPIs updated and cash monitored. The recurring engine.
6 services 02Strategic Finance Projects
One-time, fixed-fee engagements that fix something structural or produce a specific artefact — a clean-up, a model, a diligence pack.
11 services 03CFO & Growth Advisory
Senior judgement applied to the decisions that move the business: pricing, hiring, spend and runway.
6 servicesWhere this is going
Four stages are built. The fifth is not.
This is the honest state of the platform, not a launch plan. Nothing in the second and third columns exists yet, and nothing here can be bought, joined or waitlisted.

In development
Being built. Not available, and not in testing.
- A Grow layer — the fifth stage the content model already reserves and nothing yet fills
- Deeper learning above the working level, where the platform is currently thinnest
- Signed-in progress across courses, tools and saved work
Direction, not a date
Intent only. None of this has been started.
- Tools that keep state between visits rather than resetting on reload
- Scenario and simulation work built on the existing calculation engine
- An integrated finance and business workspace, if the layers below earn it
Written down so it can be held against us. If something on this page is described as live, it is live and you can open it now. If it is in the second or third column, it does not exist, and no page on this site will ask you to pay for it, join a list for it or believe it is coming on a date.
Why this site
Built to be checked.
The assumptions are visible
Every calculator states what it assumes and which rules it applies. A number you cannot interrogate is not an answer.
One decision per page
Tools are scoped to a question, not built as a dashboard of everything — which is how a tool ends up answering nothing.
Written for practitioners
For people who already know what a basis point is and want the calculation, not the introduction to it.
Free where it can be
Every tool and every glossary term is free and needs no account. Templates, guides and services are paid. Nothing else is gated.
Start with the question you actually have.
No account, no email, nothing to dismiss. Open a tool and get the number — or start at the beginning and work up.
