What Is Aon?
Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. 1,2
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. 4,5,6,7,8

What Is Professional Errors and Omissions (E&O) Insurance?
Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. 11,12,13,14
Key Differences in Professional Liability (E&O) Insurance
Coverage and Policy Design
Aon says its professional-services practice tailors E&O structures to firm needs, naming law, accounting and consulting as its focus. Founder Shield targets venture firms, consultants, media and advertising agencies, SaaS marketplaces and software developers; its E&O description includes defense costs, disciplinary or regulatory proceedings, lost earnings and errors by employees or contractors. For a venture-backed or software business, those listed protections give specific issues to test in a quote. 3 9
Buying Route and Terms
Founder Shield is a retail brokerage, not the risk-bearing insurer. It says it places coverage with carriers rated A- or better by AM Best and routes applications through its website or an advisor, then approaches carriers. Aon likewise arranges or advises and does not name the carrier for an account. Founder Shield says E&O is often packaged with tech E&O and cyber, while Aon’s overview leaves bundling open. Confirm policy boundaries and insurer. 3 9

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.[4][6][7]

Founder Shield has too little independent customer feedback for a reliable verdict. One positive Trustpilot review does not establish a service track record.[1][4]
