Most investors lose six figures to problems they could have seen.

Underground

The sewer line cracked 10 feet below the property — invisible from inside, invisible from outside.

In plain sight

The 70-unit deal where every HVAC unit was 18 years old. The CapEx broke the math.

On the report

The “clean” inspection on a 40-year-old building. The clean report wasn’t reassuring — it was a question.

If you don’t know what the hell you have, you will have the hell you own.

— Jon Weiskopf, PE

What Eyes Open Does for Real Estate Investors.

Three outcomes. One system. Sharper at every stage of owning a building.

See what’s hiding.

What inspectors don’t catch.

Stop overpaying.

Know whether the contractor is solving the right problem.

Decide with confidence.

Score, price, decide — before you write the check.

I’ve Been Reading Buildings for 20 Years.

Most real estate education teaches the spreadsheet. I read the building.

Licensed PE with 20 years engineering 400+ buildings. 9 of those years at Apple — running engineering for one of the largest retail portfolios in the world.

I founded Blue Eyed Capital because investors and operators don’t have access to what’s behind the walls. The building is the input to the spreadsheet. Eyes Open is the lens I use on my own deals — tools for real estate investors, now a catalog you can buy.

Real Words From People Who’ve Worked With Me.

Clients, counsel, and consultants on working with Jon.

“Jon made the fast call that accounted for everything at once — architecture, design, engineering, performance. His feel for how building systems actually work together was the real thing.”

Client
Energy retro-commissioning project · New York City

“We were pursuing an errors-and-omissions claim against the engineer of record, and no one on our side could assess what our consultants were telling us. Jon was the first name I thought of — the judgment we trusted when it mattered.”

In-House Counsel, Apple
A primary engineer Apple Inc. relied on

“In a landlord meeting in China, Jon caught them misrepresenting their building systems — in a language he doesn’t even speak. Afterward I asked how. He said, ‘It’s just numbers. I know what they’re supposed to be. They lied.'”
