The developer's deck answers the developer's questions.
Your investor asks different ones: the full cost, what homes nearby really rent for, and what could go wrong. Answer those, with sources, and the case is one they can check.
The case, and everything made from it.
- 01
The investor summary
All-in cost, rents from comparable homes and the hold at 3, 5 and 7 years, on one page.
Instead ofForwarding the developer's brochure.
- 02
A source beside every figure
Each number sourced and dated. What can't be sourced is left out, and the case says so.
Instead ofNumbers you'd have to check yourself.
- 03
The deck and talk track
Slides and what to say in the meeting, plus a social pack and a narrated video in your voice.
Instead ofBuilding slides the night before.

The risks, with what to do
Each risk beside what the buyer can do about it, so the case reads as honest advice.
Answers“Showing investors the risks will upset the developers.”
Why not just ChatGPT or Claude?
Keep ChatGPT for everything else. For an investor case, the sourcing and the checking are the work, and it leaves both with you.
Worries, handled.
“If the numbers are wrong, it's my name on it.”
Every figure carries its source and date. Anything we can't source is left out, and the case says so.
A source beside every figure.
“I don't trust AI with my clients.”
It never talks to your clients. You read the case, add your view and share it yourself.
You decide what's shared.
“I already use a data tool.”
Keep it. Everyone has the same data; the edge is what you say with it.
Your view, with the evidence.
“If an investor forwards it, is it an advert?”
Anything posted publicly follows your market's advertising rules. We mark which pieces are for one investor and which need approval first.
Marked before it goes public.
Real figures, their sources, and your view.
Your part: send one property, then read the case and add your view.
