7 Tech E&O Mistakes CT SaaS Startups Make (And What Each One Costs)

This is a companion to our pillar guide on Tech E&O Insurance for SaaS Startups in CT. Read the pillar for the structure of the program; read this for the seven ways founders blow it up.

Mistake #1 — Buying GL alone and assuming it covers software

The most common starter mistake. A founder buys a Business Owner's Policy (BOP) bundled with General Liability for the co-working lease and assumes "we have insurance." GL covers third-party bodily injury and property damage. It excludes pure financial loss from software performance — the exact thing that drives SaaS claims.

What it costs: A customer claim for $250K in lost revenue from a pricing-engine bug. GL denies. The founder pays defense costs out-of-pocket ($80K+) before realizing there's no coverage. Total exposure: the full $250K plus defense.

How to avoid it: Buy Tech E&O. GL stays for the office, but Tech E&O is the policy that pays when software causes financial loss.

Mistake #2 — Waiting until the first enterprise MSA forces the issue

Procurement teams at enterprise customers do not move quickly. They send the MSA, find the insurance requirement, and tell the founder they need a $3M Tech E&O / $3M Cyber certificate by Friday. Brokers can sometimes turn this around — but pricing is bad and the founder is negotiating from a desperate position.

What it costs: Premium 15–30% higher than a voluntary bind. A delayed deal close (sometimes by 2–4 weeks). Occasionally a lost deal when the procurement window closes before coverage is bound.

How to avoid it: Bind Tech E&O voluntarily, 30–60 days before signing the first enterprise customer. Most founders know roughly when the first enterprise deal is coming. Bind ahead of it.

Mistake #3 — Buying Tech E&O without Cyber

Tech E&O and Cyber cover different things. Tech E&O pays when your software fails or causes a customer's financial loss. Cyber pays when there's a data breach, ransomware, or privacy-regulator action. Modern SaaS policies bundle them — but the founder has to make sure both modules are turned on.

What it costs: A breach response event averaging $190K for a small SaaS (IBM's 2024 Cost of a Data Breach Report figures for small business). With no Cyber module, the entire cost falls on the founder.

How to avoid it: Confirm the policy has both Tech E&O and Cyber active. Most carrier forms make this easy; it's the assumption that they're equivalent that causes the gap.

Mistake #4 — Under-limiting against customer requirements

Founder buys $1M of Tech E&O because that's what the broker quoted. Six months later, an enterprise customer's MSA requires $5M. The founder either renegotiates the MSA (rare), buys a separate higher-limit policy (expensive and complicated), or loses the deal.

What it costs: $4K–$8K of additional premium to step up limits mid-term, or a lost enterprise deal worth $200K+ ARR.

How to avoid it: Read the insurance requirements in your top three target-customer MSAs before quoting. Buy limits 1.5x the highest requirement. The premium difference between $1M and $3M is usually $2K–$4K — trivial against the deal value.

Mistake #5 — Letting the policy lapse during a fundraise

Tech E&O is claims-made coverage. A lapse creates a coverage gap that prior-acts coverage can't always fix. Founders sometimes let coverage lapse during fundraise crunch — payment delayed, no autopay, "we'll fix it after close." Then a claim arrives from an incident that occurred during the lapse.

What it costs: Full claim exposure with no insurance recovery. Worst case: a $500K customer claim hits during a 6-week lapse and the founder pays the full amount.

How to avoid it: Autopay. Calendar the renewal 60 days out. Confirm payment 14 days before renewal. Treat it like payroll — it's not negotiable.

Mistake #6 — Ignoring AI-related exclusions in the policy form

In 2024 and 2025, many Tech E&O carriers added "Algorithmic Bias" or "AI Failure" exclusions to their forms. A SaaS founder who built an AI-driven product but bought a 2024-form Tech E&O policy may have a meaningful gap they don't know about.

What it costs: A discrimination claim arising from algorithmic bias — full exposure, no coverage. CFPB or similar regulatory inquiry — defense costs out-of-pocket.

How to avoid it: Ask explicitly which form version is being quoted. The 2026 forms are starting to add affirmative AI coverage. If the product uses AI in any meaningful way, insist on the AI-aware form even at higher premium.

Mistake #7 — Skipping the application's prior-acts disclosure

Every Tech E&O application asks: "Are you aware of any prior incidents, claims, threats, or disputes?" Founders sometimes answer "no" when the truthful answer is "there was a heated email exchange with one customer last quarter that hasn't been resolved." When a claim eventually arrives from that customer, the carrier denies for material misrepresentation. Worse: the carrier rescinds the policy from inception.

What it costs: The full claim exposure plus refunded premiums but no policy. Total loss of coverage for a known matter.

How to avoid it: Disclose everything. Even an unresolved customer complaint. The underwriter may sub-limit or carve out the specific matter, but the rest of the policy stays in force. Material misrepresentation is the worst possible outcome.
