About CarbonAI

Who Are We?
We Are You.

We spent years underwriting, closing, and managing CRE loans at firms including Starwood, Morgan Stanley, Argentic, and Guggenheim. A passion for improving technology in CRE inspired us to launch and lead Nativ, a portfolio management platform for CRE lenders. After rapid growth and success with over 30 lenders, Nativ was acquired by Built, a leader in CRE technology, where we took its lender business to new heights. Carbon is the culmination of that journey, arriving at the moment AI can finally carry the work.

Our Mission

CarbonAI is built to enable CRE lenders to close and manage more qualified deals with long-horizon, auditable AI agents. We break the link between deal volume and headcount, so taking on more deals no longer means taking on more cost.

What We Believe

Everything Carbon does starts here.

01

Collaboration Over Replacement

Technology should work alongside people, not in place of them. The best outcomes come from combining AI with human judgment, not swapping one out for the other.

02

Judgment Deserves Respect

Expertise is worth protecting, not automating away. The people doing this work every day deserve more time applying what they know, not less of it.

03

Trust Is Earned, Not Assumed

Trust, between people, and between people and the tools they use, is built through consistency and proof, not claimed upfront. That’s as true of how we run this company as it is for Carbon’s platform.

04

Built From the Inside, Not the Outside

The best solutions come from people who’ve done the job themselves, not people guessing at it from a distance. That’s the reason this company exists in the first place.

05

Better Lending Moves the Physical World Forward

Better lending gets capital moving faster into the housing, offices, and infrastructure the economy is waiting on.

The People Behind the Agents

Lenders, underwriters, and builders who have lived the workflows Carbon now runs.
