Launch a Program
Your program, grown here.
The greenhouse was built to hold more than our own programs. If you are an underwriter with a niche thesis, or a team with a program that deserves better, this is where it grows.
The soil
What the platform provides.
Everything a new program needs to exist: already built, already running, already proven by the four programs in market today.
Licensing & compliance
Licensed in all 50 states, with program operations, carrier reporting, and compliance run in-house, so a new program can launch with nationwide licensing already in place.
Carrier relationships
Real capacity conversations, proven by a national carrier collaboration signed within two months of our own launch. We know how to present a program carriers can say yes to.
Underwriting technology
Our proprietary, AI-enabled platform clears, triages, and accelerates submissions. New programs plug into working infrastructure, not a build-it-yourself promise.
Distribution & brand
A curated broker panel that trusts the greenhouse mark, and a partnership-first reputation your program inherits the day it launches.
The seedlings
Who we back.
Underwriters with a thesis
You know a niche cold (the classes, the losses, the mispricing) and you are ready to run your own book instead of renting your expertise to someone else’s.
Teams seeking a platform
A producing or underwriting team with proven flow that needs licensing, paper, and infrastructure, without giving up the identity you have built.
Programs that need a better home
An existing program stuck on shaky capacity, dated technology, or an inattentive administrator. Replant it where it can actually grow.
Partners with best-in-class accounts
Broker partners whose best accounts sit outside our environmental realm. Bring us the book: we help you create a specialty program around it, with appetite, structure, and capacity shaped to the best-in-class accounts you already serve.
Environmental, energy, and industrial adjacencies are the natural fit, but if you have a sharp thesis in any specialty niche, we have the platform to build it with you. Bring the idea; your pitch gets read by the founders, not a form.
The season
From pitch to market.
- 01
Pitch the program
Bring the thesis: target classes, appetite, distribution, track record, and the numbers you have. A tight two-page summary starts the conversation.
- 02
Build it together
We pressure-test the underwriting, shape the structure, and take it to capacity partners, while operations, licensing, and technology are prepared around it.
- 03
Launch and grow
Your program goes to market under the Greenhouse umbrella, with you underwriting it, the platform carrying it, and a partnership built to compound.
Or write to NewAppointment@GreenhouseSpecialty.com with a short summary; it goes straight to the founders.
We’ve walked it
Built by people who built programs.
Before Greenhouse, Josh and Geoff ran the general liability and environmental programs at another MGA, growing other people's platform with their own underwriting. They know exactly what a program builder needs, because they needed it: real carrier access, technology that works, operations that keep pace, and a partner who treats the program like it matters.
That is the platform they built: first for their own four programs, now for yours.
