Risk sharing spreads the cost of a potential loss across multiple parties instead of placing it all on one.
Risk sharing spreads the financial impact of a loss across multiple parties rather than putting it entirely on one. In insurance this shows up in the deductible and coinsurance you carry alongside your carrier, and in pooling structures like group captives and risk retention groups where similar companies share each other's losses. For a startup, sharing risk can lower your premium, but it also means you keep part of every loss on your own books, so it works best when your balance sheet can absorb that share.
Risk sharing in insurance means the cost of a loss is split across more than one party instead of falling entirely on you. The most common examples are deductibles and coinsurance, where you and your carrier each cover a portion of a claim. Broader arrangements like group captives and risk retention groups let a group of similar companies pool premiums and share each other's losses.
Risk transfer shifts the full financial burden of a loss to another party, which is what a standard insurance policy does when you pay a premium. Risk sharing keeps part of that burden with you or spreads it across a group, so no single party carries the whole loss. Most real programs combine both: you transfer catastrophic risk to a carrier while sharing smaller losses through your deductible.
Common examples include a higher deductible or self-insured retention on your liability policy, coinsurance provisions on property coverage, and membership in a risk retention group or group captive with peer companies. Each of these keeps some loss on your side in exchange for lower or more stable premiums. Your broker can model whether the savings are worth the risk you retain.
