Private Due Diligence

Due diligence on the hard-tech bet you're about to make.

The show lands the verdict in public. When you have a real project or investment on the line, I go deeper — privately, on your numbers.

What I do

Feasibility & TEA

The same techno-economic model behind every Bankable verdict, built on your project: unit economics, CAPEX/OPEX bottom-up, LCOE vs the incumbent, sensitivity and verdict-flip thresholds.

FOAK / TRL 7→9 advisory

Scale-up risk, the gap between a flawless lab coupon and a financeable plant, where the physics quietly breaks the spreadsheet — read by someone who has carried first-of-a-kind projects across the finish line.

Independent second opinion

A red-team on the deck in front of you, or the one you're about to send. Judge the technology and the economics, on the record, with sources.

Why me

You can't verify a feasibility verdict yourself — that's why you're hiring one. So the only thing that matters is whose judgment you're buying. Mine comes from six years closing first-of-a-kind commercial deals at a waste-to-fuels pioneer, a 13-country book of real projects, and licensed professional engineers behind every study sold as sealed engineering work. I bridge Western and Chinese markets in both languages — useful when the supply chain or the capital does too.

How it works

Tell me what's on the line — the form below, two minutes.

A free scoping call — is this even worth a study? I'll tell you straight.

A scoped engagement — feasibility memo, full TEA model, or an ongoing advisory retainer. Fixed-scope, P.Eng-sealed where it's sold as an engineering study.

Tell me what you're evaluating. I reply within two business days — and I'll tell you straight if it isn't worth a study.

Got it — talk soon.

I read every inquiry personally and reply within two business days. If it's time-sensitive, email hello@bankable.show with "urgent" in the subject.
