Light.Your AI senior analyst.
A full underwriting AI that operates like a senior analyst — turning raw OMs, rent rolls, and T-12s into a structured investment view, an Excel model, and an IC-ready memo. Drop the deal. Walk away. Come back to a finished underwrite.
One question. Five runs. Standard LLMs scatter. Light holds the line.
We took a single underwriting question — the kind every acquisition team asks every day — and ran it through ChatGPT and Claude five times in a row. Then through Light, five times. The LLMs returned a different bid price every run, drifting up to 27% across the set. Light came back within ±2.4%, every time, with the same Excel model attached.
Light returns the same answer because the work is the same work.
ChatGPT and Claude are tools you operate. Light is an analyst that operates for you.
A tool gives you a paragraph. You then have to chase down the missing data, verify the comps, build the Excel model yourself, and reconcile the gaps. Light arrives knowing what underwriting actually requires — and goes and does it.
- You write a careful prompt
- It returns prose with assumptions buried inside
- You hand-extract the numbers into Excel
- You verify each one against your own data
- You re-prompt for the gaps. Re-verify. Re-build.
- Two hours later: rough draft only. No memo.
- You drop the OM, rent roll, T-12 · pick a mode
- Light pulls comps & verifies recent transactions
- Builds full Excel underwrite (IRR, sensitivities)
- Validates assumptions against market data
- Generates downside / base / upside scenarios
- 30 minutes later: full underwrite + IC memo
You don’t prompt-engineer Light. You pick a mode.
Light arrives knowing six full underwriting playbooks — one for each side of the deal table. Pick the mode, drop the data, walk away. The mode tells Light what work to do, what comps to pull, what scenarios to model, and what kind of memo to write at the end.
Drop the OM. Go do important things. Come back in 30 minutes.
You don’t need to babysit Light. You don’t need to prompt-engineer it. You upload what you have, pick the mode, and get back to your day. When you return, the underwrite is finished, the Excel is built, and the IC memo is sitting in your inbox.

The team isn’t sitting at their desks operating an LLM all day. They’re sourcing deals, talking to brokers, taking meetings, building relationships. Light handles the underwriting back at the office — and presents finished work when they’re ready to look at it.

The asset classes most teams underwrite most of the time.
For these, Heavy is the right tool — full customisation, deep specialisation, institutional Excel modelling.
- Highly complex or niche assets requiring deep specialisation
- Advanced hospitality underwriting
- Specialised infrastructure-like assets
- Tailored fit to your internal investment strategy
- Integration with proprietary data & templates
- Full institutional Excel modelling at deal complexity
Three tiers. Pick the one that fits your operation.
Light replaces the analyst layer for most teams. Heavy replaces the entire underwriting infrastructure for institutional shops. ChatGPT and Claude are general-purpose tools that were never built for capital allocation in the first place.
Most teams start with Light, scale into Heavy when their volume or complexity demands the full custom stack. The two tiers are designed to coexist: Light for the everyday underwriting flow, Heavy for the deals that move the fund.
