Direct to tenant leasing
We lease directly to local businesses rather than routing every suite through third party brokerage. Shorter cycles, lower friction, and a durable relationship with the tenant base.
Flex Industrial Real Estate
Institutional discipline for small format flex industrial
Cornerstone Flex acquires and develops small bay flex industrial across high growth secondary and tertiary markets, applying self storage grade operations to a historically fragmented asset class.
The approach
A repeatable operating model, not a one off trade
Modified gross, short term leases
Modified gross structures on shorter terms keep rents aligned with the market. Rate resets happen on our schedule, not a decade after the fact.
AI enabled operations
Self storage grade systems for pricing, leasing, and collections applied to a fragmented asset class. Operating leverage without adding headcount at each site.
Our markets
Secondary and tertiary metros with real supply deficits
We underwrite markets before we underwrite buildings. The screen favors metros where small bay supply has not kept pace with local business formation and where institutional capital has not yet compressed pricing.

Why Cornerstone Flex
Operators first, sponsors second
Cornerstone Flex is led by Matthew Lang, who scaled Snapbox Self Storage to more than $1 billion in AUM and over 3 million square feet before its 2024 merger into Go Store It, where he became President of a combined portfolio of approximately $3 billion in AUM and 10 million square feet. That background informs how this firm treats flex industrial: standardized operations, direct tenant relationships, disciplined underwriting, and reporting built for institutional partners.
