We are defined by our values: Connection. Integrity. Dependability.

Our values are not just principles. They are the reason our clients never feel alone on a project.

Connection, integrity and dependability in everything we do.

We believe development is too complex and personal to be managed by distant, commoditized firms. Greenlight exists to create real connection, between owners, teams, and decisions, so our clients feel supported, understood, and never alone while building something that matters.

At Greenlight, we are driven by a commitment to genuine connection, unwavering integrity, and consistent dependability. We build lasting partnerships grounded in trust, ensuring our clients feel supported and confident throughout every stage of development.

We act as a true extension of ownership — bringing clarity, structure, and accountability to every project.

Who We're Built For:

  • Emerging developers
  • Multi-project scaling
  • Established institutional developers

We’ve been developing in New York City for over two decades, and we consider ourselves seasoned operators. We tackle many landmark and technical out of the ground projects that other developers would avoid. The projects bring great challenges that take a special team. Over the years we've had various teams struggle to get these types of projects over the finish line.

It all changed with Greenlight. Greenlight came in and did what other CM’s were unable to do. They brought clarity, structure, and a level of ownership we hadn’t seen before. Within a short period, they organized the entire closeout process, coordinated all outstanding parties, resolved compliance gaps, and got the projects officially closed. Greenlight brought immediate change to the project and as it was completed with precision and professionalism.

This performance is a breath of fresh air and raised the bar for what we believe an Owner’s Rep can be. Greenlight didn’t just manage tasks, they showed that they really cared, restored momentum and protected value. This is why we continue to awarded them additional projects. When you find a partner who can solve problems with integrity and dependability you don’t let them go.

I have been an Architect for over forty years and have worked with many developers and owner’s representatives. Matt is one of the most knowledgeable and professional. He is timely, responsive and resilient. He enables and inspires others, by example, to work cooperatively toward designing and building great enduring architecture.

The first tenant of 901 Broadway, an 1870 commercial building near Union Square was Lord and Taylor. When the store moved in 1914, the picturesque French Second Empire property was used for manufacturing and retail at the ground floor.
After years of deterioration, this project has restored the decorative cast iron and the slate roof. The signature pavilion at the corner of 20th Street and Broadway now welcomes visitors to Brooks Brothers on the lower floors, and mixed-use residential and office space on the upper levels.

Lucy G. Moses Preservation AwardThe New York Landmarks Conservancy

The restoration of 901 Broadway required a level of oversight and discipline far beyond a typical project. Between the landmark cast-iron façade, specialized restoration scope, and active structural deterioration, there was little margin for error.
Greenlight brought immediate structure, accountability, and control to a highly complex situation. Their reporting identified critical inconsistencies in contractor operations and unsupported change orders early enough for us to take decisive action before the project was compromised.

With Greenlight leading the transition and implementing a revised management structure, we were able to protect the schedule, maintain financial control, and successfully complete the project within budget and on time. The finished project ultimately received a Lucy G. Moses Preservation Award for historic preservation.

I reviewed the spreadsheet that I asked Matt to make to track all costs on our project.

First, evidentially, Matt was listening as it is spot on to what I requested. More importantly, it is a work of art! Incredible tracking tool. Haven't seen this tracking done successfully since our 17th street project in 2000!

I have been pushing every team since then for the same. Greenlight is the first to actually do it.
Thank you Matt.
