## What Is Founder Shield Insurance?

Founder Shield is a broker for venture-backed startups: you apply online in under 15 minutes, and an advisor shops its 200+ carrier markets to build a program that changes as your products and locations change. It doesn't insure you itself, so ask which insurer carries each policy.

## 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. [11](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [12](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [13](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [14](https://www.coverdash.com/coverage "Coverage Hub") [15](https://kinro.com/products "Products")

## Key Differences in Umbrella and Excess Liability Insurance

### Direct Quote Access or Broker Placement

biBerk offers online or phone access to quote its umbrella, which must accompany an existing liability policy. Founder Shield acts as a retail brokerage: after you request coverage through its website or an advisor, its placement team approaches carriers rather than binding the policy itself. That difference affects who works through the carrier options with you and when you see a specific insurer. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today") [9](https://foundershield.com/coverage/umbrella-insurance/ "Umbrella Insurance")

### Scope of the Layer

Both describe added liability protection above underlying policies. biBerk says its layer only applies to coverage included below it; Founder Shield describes protection for bodily injury, property damage, and personal liability claims such as libel or slander once primary limits are exhausted. Ask how the proposed business policy handles each underlying line, since Founder Shield’s overview also discusses personal umbrella buyers. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today") [9](https://foundershield.com/coverage/umbrella-insurance/ "Umbrella Insurance")

Founder Shield says it selects carriers rated A- or better by AM Best, but does not identify the insurer for a particular placement; biBerk’s reviewed page likewise leaves carrier detail to the quote. [6](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?") [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 Founder Shield to name the proposed carrier and confirm the quote is for a business umbrella. [9](https://foundershield.com/coverage/umbrella-insurance/ "Umbrella Insurance")
- Ask biBerk to list all underlying coverages included in its quoted layer. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today")
