## What Is Corgi Insurance?

Corgi suits technology startups wanting packages organized from pre-seed through growth, with dashboard changes as the business grows; firms seeking only a direct single-carrier policy should compare alternatives. Issuers vary by product and state.

## What Is Umbrella and Excess Liability Insurance?

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. [10](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [11](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [12](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [13](https://www.coverdash.com/coverage "Coverage Hub") [14](https://kinro.com/products "Products")

## Key Differences in Umbrella and Excess Liability Insurance

### Scheduled Policies and Drop-Down Terms

biBerk says umbrella protection only applies to lines included in the underlying policy; for example, auto claims are not added without commercial auto underneath. Corgi specifies scheduled CGL, hired and non-owned auto, and employment practices liability, then describes its layer as following those policies’ terms. Corgi says it may drop down if an underlying insurer becomes insolvent or an aggregate is exhausted, but generally not for an exclusion. Ask how each form treats an exhausted aggregate. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today") [9](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance")

### Published Limit Example

Corgi illustrates $5 million per occurrence and $5 million aggregate with no self-insured retention above scheduled underlying limits. biBerk’s page explains the excess trigger but publishes no comparable example amount. Treat Corgi’s figures as an illustration and request the limit and attachment point offered to your business. [9](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today")

Corgi lists six extension scenarios, including hired-auto and products-completed operations excess; biBerk instead emphasizes the need for the corresponding coverage below. [9](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today")

## What to Confirm in Umbrella and Excess Liability Insurance Quotes

- Ask Corgi which of its illustrated extensions and drop-down terms are in your issued form. [9](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance")
- Give biBerk your policy schedule and confirm whether every desired line is included underneath. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today")
