Is AfterQuery Legit? Expert Pay and Company Data Program

Is AfterQuery legit? The short answer

Yes. AfterQuery is a venture-backed AI data company with a public funding round, named investors and named customers. Interest in it has grown fast in 2026, and people searching for it are usually one of two kinds: professionals deciding whether to take paid expert work, and owners deciding whether to license company records.

Both are covered below. The short version: the expert work is paid contract work for a company that sells data to the largest AI labs, and the company data program is real but new, launched in late October 2026, so there is no track record of completed seller deals to judge it by yet.

What AfterQuery is: funding, customers and growth

AfterQuery calls itself "an applied research lab curating data solutions for frontier foundation model development" (AfterQuery). Its founders "founded AfterQuery in 2025" after Y Combinator (Tech Funding News).

In April 2026 it announced "our $30 million Series A at a $300 million valuation, led by Altos Ventures", said it "has surpassed $100 million in revenue run rate" and claimed that "every leading AI lab uses AfterQuery's datasets and reinforcement learning environments" (AfterQuery). Forbes reported that it competes with Mercor "to sell training data on coding and finance to AI labs like OpenAI and Anthropic" (Forbes).

In September 2026 Forbes reported that AfterQuery "has reached a $3.2 billion valuation", citing two people with direct knowledge; "AfterQuery declined to comment" (Forbes). On its homepage AfterQuery says "NVIDIA publicly used AfterQuery's Off-The-Shelf Office Agent Training Dataset to improve Nemotron 3 Ultra on GDPval" (AfterQuery).

AfterQuery for experts: what the work is and how it pays

AfterQuery "now pays experts across software engineering, finance, law, and medicine to capture how they reason through problems" (Tech Funding News). It says it works "with nearly 100,000 verified practicing professionals across engineering, medicine, law, finance, and more" (AfterQuery). The work feeds the data it sells: prompt and response pairs, grading rubrics, agent environments and "Human-demonstrated interactions across browser and desktop environments" (AfterQuery).

Rates and payment terms are set per listing and per contract. Its experts site blocks automated reading, so we have not recorded a rate here; treat the figure in your signed contract as the only one that counts, and check how hours or tasks are approved before you start.

We found no named news report alleging that AfterQuery failed to pay experts. That is a useful signal for a company of its size, though it is young: it has operated for less than two years.

Is AfterQuery legit for companies? The data partnership program

Yes. On 23 October 2026 AfterQuery wrote that "we're excited to announce AfterQuery's expansion into Data Partnerships" (AfterQuery). It "licenses records of how your teams work, from email and chat to CRM and finance, to train and evaluate frontier AI", and is "most interested in established companies with several teams working across several systems, and a few years of history". "Operating, winding-down and closed companies are all welcome" (AfterQuery).

The process: after the form, "You'll get an email with our mutual NDA and a short questionnaire about your systems and teams," and "We reply within three business days." "You decide the scope: which teams, which systems and which time window." Price is set "By depth, breadth and uniqueness: years of history, number of connected systems, the kind of work captured, and how hard it would be to recreate," and "We propose terms after reviewing a sample." It is "Usually a few weeks from first form to signed agreement" (AfterQuery).

On privacy, "sensitive categories such as payroll, privileged legal material and credentials are never used", and each dataset is checked "including a re-identification test, because no process removes all risk on its own" (AfterQuery). AfterQuery also says it anonymizes "pseudo-identifiers such as a person's location, occupation, or title", that "We are not a data marketplace built around volume," and that it turns business data into reinforcement learning environments (AfterQuery).

AfterQuery for companies at a glance

What AfterQuery publishes, and what it leaves to the agreement.

What is not known yet

The company program is weeks old, so there are no reported seller deals or published prices to compare against. The final step reads "06 Payment Payment and ongoing partnership" and gives no timing (AfterQuery). That is not a warning sign on its own, but payment timing belongs in your agreement before you share a sample.

AfterQuery does say it is not new to buying data: "We've already processed thousands of real world data assets, including codebases, financial models, and CAD designs from individuals, small businesses, and enterprises" (AfterQuery).

AfterQuery vs Mercor and other buyers

For experts, AfterQuery and Mercor do similar work for the same labs; Forbes names Mercor as its competitor. Mercor pays contractors weekly through Stripe or Wise (Mercor) and has a longer record, including reported complaints, all set out in our Is Mercor legit? review. See also our reviews of Handshake AI, Turing and Scale AI.

For companies, AfterQuery is the most explicit about what it will not use and about re-identification testing. micro1 publishes "payments typically ranging from $100K to over $3M" (micro1) and Handshake AI $100K to $4M+, while AfterQuery publishes no range. If a published number matters to you, compare programs in company data buyers compared and Mercor competitors.

How to check any buyer before you sign

With no published price, the sample review is where an AfterQuery deal is decided, so prepare before you send one. Our guide on how to vet an AI data buyer sets out each check, the AI data companies directory shows the other buyers for the same records, and what company data is worth gives the published prices to compare an offer with.

• Confirm who signs and who pays: the company itself, or an unnamed lab behind it. Get the paying entity named in the agreement.
• Get the price, the payment trigger and the payment date in writing. An estimator figure or an "up to" range is not an offer.
• Read the license: exclusive or not, how long it lasts, whether the buyer may resell or build products on your records.
• Ask what is removed before delivery (names, customers, payroll, credentials, privileged legal material) and whether you approve a sample first.

Next step

If AfterQuery has proposed terms for your records, check them against what comparable records have fetched before you sign.
