Carrier appetite summary
Entity notes - Cornerstone Insurance Producers, LLC is a specialty MGA/managing general agent focused on niche, customizable property and casualty programs nationwide, with operations in all 50 states and programs backed by A‑rated carriers. - As of 2025 the Cornerstone Insurance Producers brand is being rebranded to Alchemy Insurance Solutions; however, current producer access and programs remain in place and are still described on the cornerstoneinsurancepros.com site. Overall appetite and geography - National footprint: programs are licensed/available in all 50 states, subject to carrier, program, and underwriting-specific criteria. - Core appetite centers on: (1) self‑storage tenant insurance and associated BOP/LRO property lines, (2) artisan contractors GL & inland marine, and (3) select specialty segments such as construction/builders risk and cannabis/vape related businesses. - Facilities or accounts must meet program underwriting standards to participate (e.g., only self‑storage facilities that satisfy program underwriting requirements can offer SBOA Tenant Insurance). Key programs and target risks 1) Self‑storage tenant insurance (SBOA Tenant Insurance and similar) - Target accounts: Self‑storage facility owners/operators seeking to offer tenant insurance to their renters. - Coverage: Contents coverage for tenant’s stored property with various limit options, written on a master policy for the facility with tenants enrolled as insureds. Claims are administered by Cornerstone. - Facility eligibility: Only facilities that meet underwriting standards and receive program approval may offer the tenant insurance. Underwriters screen for facility characteristics, management quality, and risk controls; non‑compliant facilities are declined. - Preferred risks: Professionally managed self‑storage facilities with good physical security, reasonable loss history, clear lease/insurance language, and compliance with program processes. - Restricted/declined: Facilities that do not satisfy underwriting standards or lease/operational requirements are not eligible to offer the program. Certain high‑hazard exposures (e.g., storage of prohibited commodities) are controlled via lease language and policy exclusions. 2) Self‑storage and related BOP (Businessowners Policy) - Target accounts: Self‑storage facility owners/operators and related LRO/property risks looking for packaged property and liability. - Coverage: ISO‑structured BOP form including building, business personal property, business income, and liability (BI, PD, personal and advertising injury) with optional endorsements tailored to self‑storage. - Capacity: Total insured value (TIV) typically up to $5M per location on the online platform, with higher TIVs available by referral to underwriting. - Preferred risks: Well‑maintained facilities, standard construction, stable operations, and acceptable loss history. - Restricted/declined: Higher‑TIV or more complex locations require underwriting referral. Locations with significant CAT (wind/hail/wildfire) or other high‑hazard characteristics may be written only under flexible, referral‑driven guidelines and may be surcharged, sub‑limited, or declined based on carrier appetite. 3) Artisan contractors – GL & Inland Marine - Target classes: Artisan contractors (over 40 class codes) requiring general liability and optional inland marine (contractors equipment/tools/floater). - Limits: GL limits up to $1M per occurrence / $2M aggregate via the standard online program. - New ventures: Eligible, provided the principal has at least one year of experience in the same trade. - Preferred risks: Small to mid‑sized artisan contractors with light‑to‑moderate hazard operations and verifiable experience; accounts needing AI/waiver of subrogation options (available within the program). - Restricted/declined: Heavy construction, high‑hazard or structural exposures, or classes outside the online code set are generally out of appetite and may need separate wholesale brokerage placement or will be declined. 4) Specialty/wholesale brokerage placements - Cornerstone runs a wholesale group that can place admitted and non‑admitted solutions nationally for: - Self‑storage risks (outside the standard program or with special characteristics). - Specialty trade contractors and other niche commercial P&C risks. - Cannabis and vape‑related businesses (including dispensaries, cultivation and related occupancies), often on E&S paper. - Builder’s risk policies for construction projects across all U.S. states, including high wind and fire‑threatened regions, under adaptable criteria. - Preferred risks: Accounts where retail agents need access to specialized markets/programs with underwriting flexibility but reasonable risk quality and controls. - Restricted/declined: Extremely poor loss experience, lack of basic risk controls, non‑compliance with local law, or operations clearly outside available carrier appetites. Submission & broker/producer workflow - Distribution is through appointed retail agents, trading partners, and wholesalers; Cornerstone advertises more than 2,300 trading partners and a technology‑driven rate/quote/bind platform. - Online rate/quote/bind: Producers can obtain bindable quotes in minutes for core programs (self‑storage BOP and artisan contractors) using the web platform. Minimum premiums are commonly noted (e.g., BOP from about $1,250; contractors GL from about $400; adjust to current program materials as needed). - Direct underwriter access: Producers are given direct contact with program underwriters for referrals, large schedules, out‑of‑box risks, or higher limit needs (e.g., TIV above $5M, challenging geographies, builder’s risk or cannabis placements). - Program eligibility: For tenant insurance, only approved facilities that satisfy underwriting standards and program requirements can enroll; operators typically must execute program agreements and maintain specified procedures, documentation, and lease language. - Claims: Self‑storage tenant claims are handled directly by Cornerstone as administrator/TPA, with facility operators assisting in first notice of loss and documentation. Operational producer notes - Confirm whether the program is now trading under the Alchemy Insurance Solutions name but still accessed via the existing Cornerstone systems; branding is changing but underwriting authority, carrier relationships, and program structure are represented as unchanged. - For new agents, expect standard producer/wholesale agreements and may need to route through the wholesale brokerage unit for non‑program or E&S placements. - Retail brokers should be prepared to provide detailed risk information (location data, construction/protection/occupancy, loss runs, operational details, and for cannabis or builder’s risk, project specifics and regulatory compliance) to facilitate underwriting decisions. - Facilities or accounts that fail to meet underwriting or program standards (security, construction, management, loss profile, or compliance/lease requirements) should be treated as out of appetite and placed elsewhere. Because Cornerstone/Alchemy does not publish class‑by‑class exclusions publicly, always refer specific accounts to the underwriter or rate/quote/bind platform for final eligibility, pricing, and terms.
