Holding company · Massachusetts & New Hampshire

We own and operate businesses. Technology is how we run them.

Group Investments Corp holds a group of real estate and property management businesses, and manages others on behalf of their owners. Each one runs on systems our own team builds and maintains.

Our businesses Contact

Approach

Ownership and operations, under one roof.

We are not a fund. We buy, build or take on businesses we intend to run for a long time, and we do the operating work ourselves: leasing, maintenance, finance, tenant and client relations, and the software behind all of it.

Businesses we own

Companies where Group Investments Corp holds the equity and runs the operation day to day.

Businesses we manage

Properties and companies owned by others who have engaged us to operate them. The owner keeps the asset; we provide the team, the systems and the accountability.

Technology we build

An in-house engineering group develops the platforms our businesses run on: listings and availability, tenant communications, payments and reporting, infrastructure and monitoring.

Management services

For owners who want an operator, not a broker.

We take on the management of residential portfolios and small operating businesses for owners who prefer not to run them day to day. The engagement covers leasing, rent collection, maintenance, compliance, reporting and tenant relations, delivered by the same team and systems that run our own properties.

We take on a limited number of these engagements and prefer long-term relationships in Massachusetts and southern New Hampshire.

Technology

Software we build and run ourselves.

Group Investments Corp's engineering group designs, builds and operates the software its businesses run on: today the platform behind DeRosa Properties, and the same systems for the businesses we manage. Our code lives in a private GitHub organization, and Group Investments Corp is a member of the GitHub Developer Program.

Partners and vendors

Not everything is built in-house. We engage outside firms for specialised work such as office networking, security systems and development projects, and we manage those engagements directly. We also hear pitches: if you build software or tools relevant to property operations, leasing, payments or maintenance, we are open to evaluating them and will trial what fits.
