An insurance cluster is a group of insurance companies and professionals who pool their resources and expertise to offer a wider range of products and services to their clients. An insurance cluster can be valuable as you can access a range of products, services, and support resources.

Let’s do a deep dive into why you might consider the top four ranked partnerships to see which is right for your agency.
#1 SIAA

SIAA is the #1 National Independent Insurance Agency Alliance. I have worked with them for many years as an independent insurance agent and have been impressed with the resources and support they provide.
It is fueled by 48 regional Master Agencies over all 50 states of the United States and has over $10.8 billion in total written premiums. Agencies that join gain access to competitive national carriers, and unparalleled training, and they become partners with successful companies paying top-level commissions.

As I did, you will maintain complete ownership of your independent agency and book of business.
What You Gain By Joining SIAA:
Access To Top Carriers – You gain immediate access to create carrier appointments with over 30 of the top national and regional insurance companies. Through their Master Agencies, even more national, regional, and super-regional carriers are available.
Education And Training – Relevant and practical courses are exclusive to SIAA members. In addition to receiving training to build a spectacular agency, you learn how to mold a thriving business. These are available online 24/7.
If you are a start-up, you are provided access to field specialists who serve as mentors for the first 24 months as your agency is born and grown. They can teach you essential skills pertaining to marketing, accounting, technology, staffing, and other small business necessities.
Shared Profits – You will collect top-level commissions from many competitive insurance companies, profit sharing without the stress of minimums, and local and national incentives.
Attract New Customers – Partnering agencies receive the tools to draw in more clients, utilize strategies that retain those clients, and benefit from cross-sell opportunities.
Member Benefits For You And Your Staff – You can opt for discounted cyber liability coverage. You can also have group benefits for your agency with as few as two employees.
SIAA has a unique, revenue-based rating plan for Agent’s Error & Omissions coverage. This offer is for agencies less than 3 years old.
Marketing Benefits – Receive up-to-date training on your online presence and social media marketing. Assess your digital strength with audits and marketing checklists. Utilize one of our partners’ discounted websites and mobile apps.
Agent Management System – SIAA partners with many leading AMS providers, so you can get a discounted price on a management system to organize your bookings and operations. This includes the selection of a comparative rater that synthesizes nicely with the AMS you choose.

5 Ways to Get Paid – SIAA’s unique model offers you 5 ways to increase your income.
- Some of the highest commissions available from their strategic partner companies. These are paid directly to you: the agent.
- Profit sharing with larger payouts than from other agencies made directly to the agent based on your performance.
- Some Master Agencies have organized extra incentives on a local or regional basis based on new business and growth.
- SIAA Portfolio Management Service Fees (PMSF) – These fixed, quarterly incentives, unique to SIAA, are paid to the agent based on your new and renewal book of business.
- Year End PMSF – Also unique to SIAA, this is a traditional type of profit sharing paid to each agent based on their premium growth, retention, and profitability.
Additional Income Resources – SIAA also offers life insurance, group benefits, premium financing, and programs and specialty markets.
I’ve been a member of SIAA for years and couldn’t be happier. Every agent who works with SIAA is appointed a “master agency” which apparently can “make or break” the experience. Luckily for me, my master agency is run by professionals who are great.
I came from a State Farm background and was torn to either go captive or independent. With that said, after building my P&C book of business from scratch to over 1,000,000 in annual premiums, I couldn’t be happier with the decision I made and SIAA was a large part in helping me get there!
A lot of people complain about the fees they charge (which varies depending upon your contract with your master agency) but the bonuses you are capable of getting due to “profit-sharing” from the carriers usually off-sets any fees I have to pay.
On top of that, SIAA provides discount for insurance agency CRMs, gives you higher commissions rates through certain carriers via national negotiations, and tons of other perks. If you are considering which way to go, don’t hesitate to reach out to me. A large reason I built this website was to help other insurance agents navigate all of these questions.
#2 ISU Insurance Agency Network (ISU IAN)
ISU is the second largest insurance network in the U.S., controlling over $8.3 billion in written premiums with 220 agencies and 5,000 industry professionals. They consider the volume, growth, and loss ratios of potential agency partners to maintain the high quality of their network.
Committed to letting their agencies maintain complete ownership of their businesses, ISU does what it can to offer you the uncharted benefits of being part of a larger national organization without sacrificing your independence.
On average, each ISU member receives a return of over 400% on their ISU IAN membership investment, a number that’s hard to walk away from.

If down the road you choose to leave ISU, there are no exit fees, and you retain ownership of your business, clients, and relationships. They do request a ten-day termination notice.
#3 FirstChoice: A MarshBerry Company
