The J-SOLVE financial model

Modelling at the speed of the conversation.

A financial modelling framework 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.

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.

A spreadsheet

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.

J-SOLVE

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.

01

Instant financials

No macro runs — ever. The calculation is solved directly, in one pass.

02

Faster financial close

Late changes propagate immediately, so the model keeps pace with negotiation.

03

Robust — fewer human errors

No broken formulas, no cell overwrites, no fragile links across sheets.

04

Transparent stakeholder access

Controlled and intuitive access for lenders, sponsors and advisers.

05

Huge optimisation potential

Technical and financial optimisation run live during structuring.

06

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

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 protectedPassword-gated access over an encrypted connection, served from enterprise-grade hosting with automatic HTTPS, a managed firewall and built-in DDoS protection.
  • Can be hardened furtherIndividual user logins, access limited to known devices, assumptions drawn from the user end — or run entirely offline as a self-contained file, fully off the public internet.
