Financial Model Build Agent
The Financial Model Build Agent turns your RFP, term sheet and assumptions book into a project finance or investment model in a clean house structure: inputs, construction and operations timelines, revenue, costs, tax, debt sculpting, reserves and returns. It then writes the plain-language narrative that explains the model to funders, lenders and investment committees. Your modeller reviews and signs off every sheet before anything leaves the building.

The difference
From 3-6 weeks per model to 1-2 weeks
Your modellers spend their time testing assumptions and answering funder questions instead of building mechanics from a blank workbook.

Indicative figures. We measure your own baseline in the first fortnight so the numbers you see are yours.
A consistent house structure every time
Models built by different people under bid pressure drift in layout and logic, which slows review and model audit. Every model the agent builds follows the same inputs, workings and outputs architecture, so reviewers and model auditors know exactly where to look.
SA tax and debt terms built in
Corporate tax at 27%, s12B and s12BA renewable energy allowances where they apply, debt sculpted to a target DSCR and a funded DSRA are set up from the start. Your modeller spends time testing assumptions, not rebuilding mechanics.
The story funders actually read
Credit committees and investment committees want to know how the project makes money and where the risk sits. The agent drafts the narrative from the model itself, so the words and the numbers always agree.
Capabilities
Go from RFP and term sheet to a funder-ready model in days.
Built for financial modellers, project finance and transaction advisers, IPP and PPP sponsors, DFI deal teams and corporate development teams in South Africa.
Source document extraction
Reads the RFP, term sheet, PPA or concession terms and the assumptions book, and builds a sourced input sheet where every assumption points back to its document and clause.
Timelines and revenue build
Sets up construction and operations timelines with flags, and models revenue from tariffs, availability payments, energy yield or demand, with CPI indexation as the contract requires.
Costs and SA tax
Models capex, opex, O&M fees and lifecycle costs, and calculates SA corporate tax at 27% with capital allowances such as s12B and s12BA where applicable.
Debt sculpting and reserves
Sculpts senior debt repayments to a target DSCR, sizes the DSRA and other reserve accounts, and tests distribution lock-up and covenant ratios such as DSCR and LLCR.
Returns and sensitivities
Calculates project and equity IRR, NPV and payback, and runs the sensitivities and scenarios lenders and committees ask for, from capex overruns to rate and yield shocks.
Model narrative and checks
Builds integrity checks that balance the statements and cash flows, then drafts a plain-language model narrative for funders and committees in your house style.
How it works
From your systems to a result you sign off
Your modeller reviews and signs off every sheet, and the model goes to funders or model audit only once approved.

Deployment
Runs inside the tools your team already uses
The same agent and the same cited output, delivered three ways: through the AI assistant you have rolled out, on a model you host yourself, or inside your own software.
In the frontier assistant you already pay for
We publish the agent as an MCP server. Add it as a connector and your team calls it from the chat they use every day, with no new tool to learn.

On a model you host yourself
Run the agent on open-weight models in your data centre or private cloud. Your financial models never leave your network, which keeps POPIA and data residency straightforward.
- Llama
- Mistral
- Ollama
- or any OpenAI-compatible endpoint
Inside your own software
Trigger a run from your own workflows, and push the finished output into your ERP, GRC or reporting systems. We build the integration with your team.
- REST API
- Webhooks
- Batch jobs
- Embeddable review panel
Governed the same way, every route
Whichever way your team reaches the agent, identity, permissions and audit stay with your existing controls.
- Single sign-on through Entra ID, Okta or Google Workspace
- Reads only the documents each user is already allowed to open
- Every tool call written to an audit log you can export
How we deliver it
One agent, three ways to hold it
Start where your team already works, then take it as far into your systems as the value justifies.
DATA SECURITY & PRIVACY
Your financial models stay yours.
The agent runs inside your tenancy, reads only what each task needs, and never trains on your financial models. Every step is logged so your auditors can see exactly what it touched.
Built for regulated work.
+YOUR FINANCIAL MODELS NEVER LEAVE YOUR ENVIRONMENT
