Workers' compensation is a statutory obligation in nearly every state once you have employees, and it is written state by state. A distributed team typically needs more states on the policy, not fewer. Ohio, North Dakota, Washington and Wyoming require coverage from a state fund rather than a private carrier, which catches companies out when the first hire lands there.
Employment practices liability is the other half. A technology company is far more likely to face an employment claim than a securities claim or a catastrophic breach, and the probability rises sharply with headcount, with hiring across states, and with any reduction in force. California, New York, New Jersey and Illinois are meaningfully more active jurisdictions.
This is maintenance work rather than a one-time purchase, and it is exactly the kind of thing that gets forgotten until an audit or a claim. We keep the state schedule current as you hire.
