The "Super Like" button - that little blue star Tinder users tap to signal more-than-casual interest - has generated a decade of legal grief for the company that built it. Now, the litigation spawned by a single feature has produced what may be its most consequential chapter yet: a broker malpractice lawsuit that strikes at the heart of what insurance professionals owe the clients they serve.

Match Group, the parent company of Tinder, has filed a complaint this week in New York Supreme Court, New York County, accusing Marsh USA - one of the world's largest insurance brokers - of failing to notify Tinder's insurer of a claim before the relevant policy expired in August 2016. Marsh violated its broker services agreement by failing to notify a Beazley unit of a claim against Tinder before the policy expired, Tinder alleged. The company is seeking to recover $2.9 million in damages from the underlying lawsuit plus nearly $1 million in legal fees.

The filing is the latest - and perhaps final - turn in a saga that has wound its way through federal district court, the Second Circuit Court of Appeals, and now into state court with a new defendant. For insurance professionals, every step of the journey offers an object lesson in what can go wrong when claims-made policy mechanics and broker responsibilities are not taken with absolute seriousness.

A Consultant, a Shopping Mall, and a Missed Deadline

The story begins not in a courtroom but, improbably, in a shopping mall. Match Group was sued by John Mellesmoen, a product-development consultant who alleged that he was not paid for inventing the app's "Super Like" feature. Mellesmoen's attorneys sent Tinder a letter in February 2016, outlining his alleged meeting with Sean Rad, Tinder's then-CEO, at a shopping mall where Mellesmoen first pitched his idea for the feature.

Tinder did not treat that February letter as a formal claim requiring notice to its insurer - a decision that would later prove costly. The consultant filed suit against Tinder on Wednesday, August 17, 2016, and Tinder's insurance broker provided notice to the insurer at 8:42 a.m. on Monday, August 22, 2016. Tinder's insurer denied coverage on the grounds that the February 2016 letter was a claim and the policy had expired over the weekend, on Saturday, August 20, 2016, rendering the notice untimely.

The Courts Weigh In - Against Tinder

Match Group sued Beazley in 2022, seeking coverage and arguing that Mellesmoen's February 2016 letter did not constitute a formal "claim" under the policy. The policy defined a "claim" as a "demand for money or services, including the service of a suit or institution of arbitration proceedings" or "a threat of a suit seeking injunctive relief." Tinder argued that while the letter was explicitly a "threat of a suit," it did not seek injunctive relief, and was not a demand for money but rather an invitation to negotiate toward an amicable resolution.

The district court initially sided with Tinder. The Second Circuit did not. On review, the Second Circuit sided with the insurer, holding that Mellesmoen's letter qualified as a "claim" under the policy, thereby triggering Tinder's obligation to report the claim before the end of the policy period. The court reasoned that even though Mellesmoen did not outright demand a sum certain, by stating in his letter that he had legal claims against Tinder that he believed he was entitled to compensation for, the letter met the policy's definition.

The Broker in the Crosshairs

The new lawsuit against Marsh crystallizes a question that insurance law practitioners had been anticipating since the Beazley litigation began. Legal commentators had noted that if Tinder found itself out of luck based on late notice, when it had provided the lawsuit to the broker in what it considered a timely manner, and a Marsh employee decided to "deal with it Monday morning," a broker malpractice claim was the foreseeable next step.

That step has now been taken. Marsh has not publicly commented on the filing. Beazley is not a party to the new action.

The case highlights a specific and serious duty that brokers carry when handling clients' claims-made policies. Unlike occurrence-based policies - which respond to events that happen during the policy period, whenever the claim is eventually filed - claims-made policies require that both the claim and the notice to the insurer fall within the policy period, or within any applicable grace period. The difference between Friday afternoon and Monday morning can mean the difference between coverage and none at all.

Tinder and its broker presumably expected the policy would respond to any claim made during the policy period and reported within a reasonable time. That is not what the policy said. And critically, had Tinder realized that the policy contained a stringent limitation on the notice grace period - which applied only to claims made in the last 60 days of the policy period - it might have expedited notice to the insurer when it received the lawsuit three days before expiration.

What Every Broker Needs to Take From This

The Tinder-Marsh case is not an obscure technical dispute. It is a real-world demonstration of the consequences that flow from a gap - however small, however inadvertent - in broker execution. For professionals across the industry, several lessons emerge with unusual clarity.

The Friday-to-Monday gap is real and it is dangerous. When a client forwards a lawsuit or a demand letter late in a policy period, particularly near a weekend or holiday, the broker cannot assume the next business day will suffice. Brokers need to take that extra step of confirming the policy expiration date in real time and acting accordingly, even if it means handling the notice over the weekend.

Pre-litigation letters can be claims. The February 2016 letter that Tinder received from Mellesmoen's attorneys did not include a formal dollar demand. It expressed that Mellesmoen believed he was owed compensation and suggested he might sue. That was enough for the Second Circuit. Brokers advising clients on claims-made policies must ensure that any letter asserting rights or hinting at legal action is evaluated immediately against the policy's definition of "claim" - not assumed to be a preliminary matter that can wait.

Policy language review is a core part of the broker's job. Not every broker does the deep dive into what the policy language actually says. In this case, a careful review of the grace period provision - which protected only claims made in the final 60 days of the policy, not earlier claims reported late - might have changed how both Tinder and Marsh managed the August 2016 timeline.

The E&O exposure is substantial. The damages Tinder is seeking - nearly $4 million in combined litigation costs and legal fees - are a direct reflection of what was lost when coverage was denied. That liability now sits with the broker. For Marsh, a company with global scale, the dollar amount may be manageable. For a smaller brokerage facing equivalent facts, it could be existential.

A Case the Industry Will Be Watching

The lawsuit lands at a moment when broker errors and omissions claims are under heightened scrutiny across the profession. The Tinder case, given its high-profile parties, detailed public court record, and unusually clean fact pattern - a concrete deadline, a documented notification gap, and a quantifiable loss - is likely to become a reference point in E&O discussions for years to come.

The irony is that the underlying event was entirely preventable. A lawsuit arrived on a Wednesday. The policy expired on a Saturday. Notice was sent on a Monday. Somewhere in that 96-hour window, a coverage dispute worth nearly $4 million was born - and the question of who ultimately bears that cost is now before the New York courts.

For brokers handling claims-made policies for any client, in any industry, the answer to that question matters enormously
