Sunset Review: Is Sunset Legit? Replay Data Deals Explained

Is Sunset legit? The short answer

Yes. Sunset is a real company that has run startup wind-downs since 2023, and Replay is the part of the same business that licenses company data to AI labs. Both websites carry the same legal name, Sunsets HQ Corp. Neither is a scam by any public measure we could find: no named outlet or court filing alleges misconduct.

The questions worth asking are commercial, not about legitimacy. Replay's offers are built around a perpetual revenue share, it does not name the labs that buy, and its payout bands are its own marketing figures.

How Sunset and Replay relate

Sunset is the wind-down service. Its homepage says it "handles all the legal, tax, and operational work to wind down your startup" and offers to "License your operating data to frontier AI labs after it's de-identified, or sell, assign, and auction remaining assets and IP" (Sunset). The footer reads "© 2026 Sunsets HQ Corp."

Replay is the data business. Its footer names the same company, and its founder writes: "And I started one called Sunset, which has helped thousands of founders wind down their companies" (Replay). Sunset's data page splits the work plainly: "Replay handles the data work; Sunset handles the rest of the wind-down", and a company that is still running and only wants to license data is told to "start with Replay at replay.ai" (Sunset).

So "Sunset" and "Replay" are not two competing buyers. If you are shutting down, Sunset can run the wind-down and route the data through Replay. If you are operating, you deal with Replay directly. WIRED reported in November 2026 that Sunset also emails founders cold, describing a process of "scrubbing and anonymizing the data so the company people and any identifying details are stripped out" before licensing to labs (WIRED).

Sunset's track record and funding

TechCrunch reported in February 2024 that "Sunset announced it has raised $1.45 million in seed funding", mostly from angel investors, and that CEO Brendan Mahony had earlier founded and sold a Y Combinator company: "Mahony started Toybox, a Y Combinator alumni company, in 2017 before selling it in 2020" (TechCrunch).

MIT Technology Review wrote in October 2026 that "Industry rival Sunset also has a rapidly growing data resale business", and that Sunset values a closing client's assets "by head count, years in operation, volume of data, and how the team used its tools" (MIT Technology Review). Sunset itself claims it has "Redistributed $100s of millions to the world's best investors" and promises "One team, one fee, fully managed", with "attorneys, CPAs, and a Client Success lead assigned to your case" (Sunset). It does not publish the fee.

What Replay buys

Replay lists "Historical operating data Code and commits Decision threads Financial Records Support History Product logs Presentations CRM Data Sales conversations" among the records it licenses (Replay). It says it works in any industry: "What matters isn't what you do, it's whether there's a record of how you did it", meaning communications, tickets, dispatch logs and project histories.

On the buy side, Replay shows labs a catalog where they "view datasets by industry, company size, and systems in scope", and says it takes rights from sellers so it can license onward: "We license data directly from the businesses that produce it and hold the full rights and titles to license it onward" (Replay). That is the key structural point. You license to Replay, and Replay licenses to the labs, possibly more than one.

Its homepage says: "Your data is only sold to frontier AI and data labs" and "Your data is never sold to foreign adversaries" (Replay). It does not name the labs.

What Replay pays: bands, upfront fee and revenue share

Replay publishes three bands on its homepage, read on 10 November 2026: "$10K - $100K 20 - 50 Employees $100K - $1M 50 - 250 Employees $1,000,000+ 250+ Employees". It adds that "Headcount is a proxy" and that "How long you've been operating, what industry you're in, which apps you run on and how much data sits in each all factor into the final price" (Replay).

The structure has two parts. Offers "are typically structured with a perpetual revenue share", and "You're paid a revenue share of every license." Replay says "You're paid for your historical data first. New data you produce follows the same path, and continues to pay you."

Replay claims "Millions Paid to businesses like yours" (Replay). We found no independent report of a specific Replay deal amount, so treat the bands as a starting range, not a quote. For context on what other buyers have paid, see what AI companies have paid for company data.

Size, history and language requirements

Replay's referral page lists who qualifies: "20+ full-time employees Headcount is where most valuations start", and "English-language operations US companies preferred" (Replay). Its valuation form asks for industry, location, years of operation, peak headcount, the share of work communication in English, whether you keep your own codebase, and "Is your business still operational?" (Replay). Closed companies can apply; Sunset notes that different qualification criteria apply than for a Sunset wind-down.

Replay says the owner's time commitment is "Four steps. 120 minutes of your time." That is the owner's time, not the calendar time to payment, which Replay does not publish.

Rights, exclusivity and privacy terms

Replay's privacy page makes several commitments worth getting into the contract: "This is a license, not a sale"; "Raw data is used only for de-identification; only the cleaned output is ever licensed"; "If you decide not to continue, your data is deleted from Replay on request"; and on liability, "we cap your exposure to just the fees paid" (Replay). It says its de-identification "covers 60+ categories", and its homepage claims its model finds 99% of personal information on its own benchmark.

Replay does not publish whether a license is exclusive. Because it holds rights to license onward and pays a revenue share, ask whether you may also license the same data to anyone else, for how long, and what happens to onward licenses if you end the arrangement. Our guide to exclusive and non-exclusive data licenses explains what each option costs you.

Limits and concerns

The market concern is visibility. MIT Technology Review wrote that "Founders have little to no visibility into who is buying the data and what they plan to do with it" (MIT Technology Review). Replay names no labs, so ask which buyers have licensed similar data and whether you can veto any.

A perpetual revenue share sounds generous, but it is only worth what onward licenses actually earn, and you cannot easily check that. Ask for a statement on every license, audit rights, and a clear rule for what Replay keeps. For a closing startup, having one company run both the wind-down and the data license means one team and one process; the trade-off is that the same company values the data and earns from licensing it, so get the valuation in writing and compare routes in SimpleClosure alternatives and our SimpleClosure review.

What to check before you sign with Sunset or Replay

• The upfront fee in writing, and the revenue-share percentage, with how it is calculated.
• Statements and audit rights for onward licenses, since the share is perpetual.
• Exclusivity: can you license the same records elsewhere, and for how long.
• Which labs may receive the data, and whether you can exclude any.
• The liability cap and the deletion right, copied into the agreement, not just the website.
• For a wind-down: Sunset's fee in writing, and whether data proceeds cover the wind-down or go back to investors. See how to shut down a startup and selling a defunct company's data.
• How the buyer compares with others: see our AI data companies directory and how to vet an AI data buyer.
