Common Insurance Mistakes Software Startups Make

When you're launching a software startup, insurance probably isn't top of your priority list. You're focused on product development, securing funding, and building your user base. But overlooking insurance can expose your business to catastrophic financial and legal risks that could derail everything you've worked for.

Many software startups make critical insurance mistakes that leave them vulnerable to lawsuits, data breaches, and regulatory penalties. Some don't have any insurance at all, while others have inadequate coverage that won't protect them when they need it most. Understanding these common pitfalls can help you avoid costly errors and build a solid risk management foundation for your business.

Mistake #1: Operating Without Professional Indemnity Insurance

The most dangerous mistake software startups make is operating without professional indemnity insurance (also called errors and omissions or E&O insurance). This coverage protects your business when clients claim your software caused them financial loss through errors, omissions, or negligence.

Software is inherently complex. Bugs happen. Updates can cause unexpected issues. A single coding error could result in a client losing thousands of pounds in revenue or data. Without professional indemnity insurance, you'd be personally liable for these losses, potentially bankrupting your startup.

Many founders assume their general liability policy covers professional services, but it doesn't. General liability covers bodily injury and property damage—not the financial losses clients suffer from faulty software or poor advice. Professional indemnity insurance specifically covers claims arising from your professional services and expertise.

The cost of professional indemnity insurance for software startups is surprisingly affordable, typically ranging from £500 to £3,000 annually depending on your revenue, number of employees, and claims history. Compared to a single lawsuit, this is negligible. More importantly, many enterprise clients won't work with you without proof of professional indemnity coverage. It's often a contractual requirement.

Mistake #2: Ignoring Cyber Insurance

Cyber insurance is non-negotiable for software startups. Your business stores sensitive data—client information, payment details, intellectual property, and proprietary code. A data breach could expose this information, resulting in regulatory fines, legal liability, and reputational damage.

Many startups assume cyber insurance is only for large enterprises, but it's essential for businesses of any size. Hackers target startups precisely because they often have weaker security infrastructure and less awareness of cyber threats.

Cyber insurance typically covers:

• Data breach notification costs

• Regulatory fines and penalties

• Legal defense costs

• Business interruption losses

• Reputational harm and crisis management

• Ransomware recovery and extortion payments

• Network security liability

Without cyber insurance, a single breach could cost your startup hundreds of thousands of pounds. With it, you have financial protection and access to specialist breach response teams who can minimize damage.

The mistake isn't just failing to get cyber insurance—it's getting inadequate coverage. Many startups purchase minimal policies that don't reflect their actual data exposure. Review your coverage limits annually and ensure they match your business growth and data volumes.

Mistake #3: Underestimating Liability Exposure

Software startups often underestimate how much liability they're actually exposed to. They think their software is just a tool, so liability should be minimal. In reality, software can have significant financial and operational consequences for clients.

Consider these scenarios:

Scenario 1: Your accounting software has a bug that causes a client to submit incorrect tax filings, resulting in £50,000 in penalties and interest.

Scenario 2: Your project management platform goes down for 48 hours, causing a client to miss critical deadlines and lose a major contract worth £200,000.

Scenario 3: Your API integration tool corrupts a client's database, resulting in permanent data loss and business disruption costing £100,000+.

These aren't hypothetical—they happen regularly. And clients will pursue legal action to recover losses. Your liability insurance needs to reflect realistic worst-case scenarios, not just theoretical risks.

Many startups purchase coverage limits of £1 million, assuming that's sufficient. But for clients with significant operations, losses could easily exceed this. If you're working with enterprise clients or handling mission-critical systems, you should consider coverage limits of £2-5 million or higher.

Mistake #4: Failing to Update Coverage as the Business Grows

Your insurance needs change as your startup grows. A policy designed for a three-person team with £100,000 annual revenue won't adequately protect a 15-person company generating £1 million in revenue.

Many startups purchase insurance once and never revisit it. They assume the policy will automatically adjust or that their coverage remains appropriate. This is a critical mistake.

As you grow, you need to:

• Increase liability limits to reflect higher revenue and client exposure

• Expand coverage to include new services or products

• Add employment practices liability insurance if you're hiring staff

• Increase cyber insurance limits as you store more client data

• Review professional indemnity coverage to ensure it covers all your services

Insurance brokers recommend reviewing your coverage annually or whenever your business undergoes significant changes—new product launches, geographic expansion, major client acquisitions, or staff growth.

Mistake #5: Overlooking Employment Practices Liability Insurance

As your startup grows and you hire employees, you become exposed to employment-related claims. These include wrongful termination, discrimination, harassment, and wage disputes.

Many founders assume employment disputes won't happen in their startup culture. But employment claims are increasingly common, and even unfounded allegations can be expensive to defend. Legal costs for employment disputes often exceed £10,000, even if you ultimately win the case.

Employment practices liability insurance (EPLI) covers:

• Legal defense costs

• Settlement and judgment costs

• Regulatory investigation costs

• Workplace harassment and discrimination claims

• Wrongful termination claims

• Wage and hour disputes

EPLI is particularly important for startups because you're likely operating with limited HR infrastructure and processes. You may not have formal HR policies, documented performance reviews, or clear termination procedures—all of which increase your risk profile.

Mistake #6: Not Having Adequate General Liability Coverage

While professional indemnity and cyber insurance are critical, many startups neglect basic general liability coverage. This protects your business from claims of bodily injury or property damage.

You might think general liability isn't relevant for a software startup. But consider:

• A client visits your office and trips on a cable, suffering a serious injury

• Your employee damages a client's equipment during an on-site installation

• Someone is injured at an event your startup hosts

• Your office equipment causes a fire that damages neighboring properties

General liability insurance covers these scenarios. Coverage limits typically start at £1 million and are relatively inexpensive—often £300-800 annually for startups.

The mistake isn't just failing to have general liability insurance; it's having inadequate limits. If you work with clients on-site or host events, ensure your coverage is sufficient for realistic injury scenarios.

Mistake #7: Misunderstanding Policy Exclusions

Many startups purchase insurance policies without fully understanding what's excluded. They assume they're covered for everything, only to discover critical gaps when they file a claim.

Common exclusions in software startup policies include:

• Prior acts exclusions: Coverage doesn't apply to work performed before the policy start date

• Contractual liability exclusions: Claims arising from specific contract terms aren't covered

• Regulatory fines exclusions: Penalties from regulatory bodies may not be covered

• Cyber extortion exclusions: Some policies don't cover ransomware or extortion demands

• Intellectual property exclusions: Claims related to copyright or patent infringement may not be covered

Before purchasing any policy, carefully review the exclusions section. Ask your broker to explain what's not covered and whether you need additional policies to fill gaps. Don't assume coverage exists—verify it explicitly.

Mistake #8: Choosing Policies Based Solely on Price

Cost is important, but it shouldn't be your only consideration when selecting insurance. Choosing the cheapest policy available often means sacrificing coverage quality, limits, or claims support.

Some budget insurers:

• Offer minimal coverage limits

• Have strict exclusions

• Provide poor claims support

• Take months to settle claims

• Don't understand the software industry

When evaluating insurance, consider:

• Coverage quality: Does the policy actually cover your risks?

• Limits: Are they sufficient for your business?

• Exclusions: What's not covered?

• Claims process: How quickly do they settle claims?

• Industry expertise: Do they understand software startups?

• Support: Can you reach someone who understands your business?

A policy that's £200 cheaper annually but takes six months to settle a claim isn't a bargain. Invest in quality coverage from insurers who understand the software industry and provide responsive claims support.

Mistake #9: Not Having Cyber Liability Coverage for Third-Party Data

Many startups collect and store data on behalf of clients—customer information, payment details, health records, or other sensitive information. If this data is breached, you're liable for notifying affected individuals, regulatory investigations, and potential lawsuits.

Standard cyber insurance covers your own data breach, but you also need cyber liability coverage that protects you when you're holding third-party data. This is sometimes called "privacy liability" or "network security liability."

The coverage should include:

• Notification costs for affected individuals

• Regulatory investigation costs

• Legal defense for affected individuals' lawsuits

• Credit monitoring services

• Public relations and crisis management

Without this coverage, a data breach involving client data could bankrupt your startup. With it, you have financial protection and access to specialists who can manage the response.

Mistake #10: Failing to Document Your Risk Management Practices

Insurance companies want to see that you're actively managing risks. If you can't demonstrate reasonable security practices, cyber insurance claims may be denied or coverage may be limited.

Document your risk management practices, including:

• Security policies and procedures

• Employee training on data protection

• Access controls and authentication systems

• Regular security audits and penetration testing

• Incident response procedures

• Backup and disaster recovery processes

• Compliance with relevant regulations (GDPR, CCPA, etc.)

This documentation serves two purposes. First, it demonstrates to insurers that you're managing risks responsibly, which can lower your premiums. Second, if you need to file a claim, you can show that you were taking reasonable precautions, which strengthens your claim.

Getting the Right Insurance for Your Startup

The insurance needs of software startups vary significantly based on:

• Business model: SaaS, custom development, consulting, or hybrid

• Client base: Enterprise, mid-market, or SME

• Data sensitivity: What type of data do you handle?

• Revenue: Higher revenue typically means higher liability exposure

• Team size: More employees mean more employment-related risks

• Geographic reach: Operating internationally adds complexity

Rather than trying to figure this out alone, work with an insurance broker who specializes in software startups. They can assess your specific risks and recommend appropriate coverage. The cost of professional advice is minimal compared to the cost of inadequate insurance.
