Re-checks a giant ledger by hand
And re-does the whole thing repeatedly, just to size the debt. Seconds to minutes, every time — and you wait.
The J-SOLVE financial model
Modelling at the speed of the conversation.
A financial modelling platform built out of project finance structuring practice — not a spreadsheet add-in. Same maths, reconciled to the decimal, solved directly instead of by repeated trial and error. Owned and developed by JCAP Advisory.
The problem
Where spreadsheets run out of road.
- Excel models break at scaleData-heavy projects push workbooks past the point of reliability.
- Macros slow you downEvery sizing iteration is a coffee break in the middle of a negotiation.
- Human errorsBroken formulas and cell overwrites are found late — or not at all.
- Limited optimisationTrial-and-error sizing leaves technical and financial value on the table.
Why it is instant
Same maths — solved directly.
Holds the calculation in memory
And works it out in one direct pass — no flipping through pages, no trial-and-error. Instant, and live in the room.
Benefits
Why J-SOLVE.
Instant financials
No macro runs — ever. The calculation is solved directly, in one pass.
Faster financial close
Late changes propagate immediately, so the model keeps pace with negotiation.
Robust — fewer human errors
No broken formulas, no cell overwrites, no fragile links across sheets.
Transparent stakeholder access
Controlled and intuitive access for lenders, sponsors and advisers.
Huge optimisation potential
Technical and financial optimisation run live during structuring.
AI-assisted, built in
Stakeholders interrogate the model by asking questions in plain English.
Geared towards
Data-heavy projects
Complex transactions — aggregator and trader models
Integration with asset management operations
The platform
Developed continuously, configured per deal.
J-SOLVE is not a one-off model. It is a platform JCAP Advisory keeps building: each transaction runs on its own configured instance, every change goes through a change desk with a log, and the whole model exports to a FAST-standard Excel workbook that reconciles to the browser engine.
- One engine, many instancesInputs, structure and reporting configured to the transaction; the calculation engine shared across all of them.
- Change desk and logEvery change proposed, approved and recorded — with the headline metrics before and after.
- FAST Excel exportA full workbook for lenders and auditors who want the spreadsheet, reconciled to the decimal.
- Project extensionsRefinancing packs, scenario batches and bespoke reports scoped and built per client.
Security
Secure by design — and can be locked down further.
The model runs on your device, in the browser — not on a server. Your inputs never leave the room, and there is no database that can be breached. A server-run model has to defend an internet-facing machine; J-SOLVE has no backend doing the maths, so there is far less to attack.
- Already protectedIndividual sign-in over an encrypted connection, served from enterprise-grade hosting with automatic HTTPS, a managed firewall and built-in DDoS protection.
- Can be hardened furtherAccess limited to known devices, assumptions drawn from the user end — or run entirely offline as a self-contained file, fully off the public internet.
Next step
Let us try it out first.
- Demo runSee and feel the platform on a live transaction structure.
- Trial runUse it on a single actual transaction from your portfolio.
- Roll-outAdapt the platform to how your team actually works — over time, at the pace the cost-benefit supports.
