At-Bay vs HUB International: How Do They Compare for Business Insurance?

At-Bay offers cyber, technology E&O and miscellaneous professional liability, with coverage described as underwritten by non-admitted insurers. At-Bay Insurance Services LLC is its disclosed property-and-casualty agency and surplus-lines broker. ^1,5Company-reportedUS brand and disclosed producer; company statements, not regulatory verification.

Does not establish that every HUB office places business through Insureon, or that TechInsurance is a distinct California producer.

Large technology companies may fit At-Bay’s published Tech E&O appetite, but the quote route matters: its product page lists up to $5 billion revenue and $10 million limits, while its broker platform lists $100 million and $3 million. These are ceilings, not guaranteed offers. ²Company-reportedCurrent product-page appetite; no inference of pre-revenue, industry-specific or California eligibility.

A September 2023 Tech E&O appetite PDF still accessible on At-Bay’s site has lower revenue and limit ceilings than the current product page and lists restricted classes including autonomous AI.

Bay Area technology, venture-capital, healthcare, life-sciences, real-estate and construction businesses can contact HUB’s San Francisco team; this is a local service description, not a product eligibility list. ^14,15Company-reportedHUB International San Francisco office page at 201 Mission Street.

Technology companies can ask HUB about E&O, cyber, D&O, transactional coverage, workers’ compensation and benefits; HUB says it currently insures 5,000+ technology companies, a company-reported figure. ²³Company-reportedIndustry marketing page only. Does not establish California eligibility, insurer panels or policy wording for any named coverage.

Businesses with 50 or fewer employees or under $5 million revenue are directed by HUB to Insureon’s online quote; larger or different commercial accounts go to HUB advisors. These are routing guidelines, not a legal small-business definition. ²¹Company-reportedHUB contact-us Business Solutions copy as of 16 September 2026. Actual Insureon underwriting appetite can differ by product and insurer.

An online quote is not bound coverage; At-Bay’s broker process still requires application review, chosen limits and retentions, documents, effective date, contingencies and signatures before binding. ^6,4Company-reportedPublic broker workflow; no application submitted and no speed guarantee inferred.

Small accounts meeting HUB’s size guidelines can start an online Insureon quote; other buyers contact a HUB broker or local office.
