Defined.ai Review: Is It Legit, and How It Pays Partners

Is Defined.ai legit? The short answer

Yes. Defined.ai is a ten-year-old company with named investors, published certifications and a marketplace where AI teams buy licensed datasets. Unlike most names on this list, it pays both sides: businesses that license data through its marketplace, and individuals who complete small tasks through its Neevo app.

People searching "is Defined.ai legit" are usually either a data owner who has been approached, or a contributor weighing Neevo. This page covers both, plus what named outlets reported about the company in 2026. Facts were checked on 10 November 2026, the day Defined.ai relaunched its marketplace at Web Summit.

What Defined.ai is: history, funding and the marketplace

"Defined.ai was founded in 2015", and "CEO Daniela Braga founded the company in Seattle, WA" with an R&D center in Lisbon (Defined.ai). It started as DefinedCrowd, a crowdsourcing company, and its legal notices still read DefinedCrowd. Its marketplace launched later as a place "where professionals can buy or sell training data".

In January 2026 it said "The company reported 65% Year-over-Year revenue growth" for 2025, that "Several partners now generate more than $1 million annually by licensing proprietary datasets through the marketplace", and that "The company has raised over $85 million in funding" (Defined.ai).

On 10 November 2026 Braga presented an expanded marketplace at Web Summit. ECO reports that the catalogue "reúne cerca de dez petabytes" of data, about ten petabytes, with almost two thousand datasets, and that the marketplace "já representa 70% das receitas da tecnológica", already 70% of the company's revenue (ECO). Público reported that every dataset has an identified origin and paid rights: "todos com origem identificada e direitos pagos" (Público).

Defined.ai for companies: the Data Partner program

The Partnership Programs page is aimed at "Any business that generates or aggregates data", offering audio, video, image, text or multimodal data, with "Licensing fees from data marketplace sales" as the revenue. It names the kind of company it wants: one that generates sales, marketing or logistics data in its operations and does not yet monetize it.

The page shows "$600K+ Average partner revenue" and "$1M+ Revenue for 5+ partners". Pricing is per deal: "Commercial terms depend on the dataset type, usage, and customer needs, and are always aligned with and approved by the partner." There is no fixed minimum dataset size, and Defined.ai says smaller or niche datasets may still be valuable.

Onboarding has four steps: create an account in its Jira-based portal, market research into commercial opportunities, an evaluation of data quality, volume and metadata, and an "Assessment of your licensing rights as well as legal, compliance and cybersecurity checks". It is actively looking for cinematic video, anime, coding and STEM data, with an expedited path for those.

Before any deal, applicants accept supplier terms that grant Defined.ai "a worldwide, free, non-exclusive and unencumbered license to share the data samples" with its customers to gauge interest (Defined.ai supplier terms). The commercial terms come later in a separate data license agreement.

Defined.ai for individuals: Neevo pay and payment

Individuals work through Neevo, Defined.ai's contributor community. Its App Store listing says: "Payment varies depending on the task, but Neevo Contributors average $10-15/per hour (usually working in 10-15 minute chunks of time)" (App Store). Tasks include drawing boxes around objects, tagging text and transcribing audio. Joining needs, in Neevo's words, "A PayPal account" (Neevo).

Defined.ai says of the people in its datasets: "We have a fair pay policy, ensuring at least minimum wage payment", with rates set by the ability to attract contributors and higher pay for specialist work (Defined.ai FAQ). Work depends on client demand, so jobs come and go, and Neevo itself tells applicants that job availability is outside its control.

Call recordings and audio: Defined.ai's strongest category

Speech is a long-standing Defined.ai category. Its FAQ describes scripted, dialogue and IVR (phone-system) recordings, noting that for IVR "there is only 1 channel with human speech" (Defined.ai FAQ). That makes it one of the obvious places a contact centre, telecom or podcast owner hears about.

Archived customer calls are harder to license than they look. Defined.ai requires "the right to commercialize the data for AI training", with consent and documentation, so a recording made under a "this call may be recorded for training purposes" notice may not qualify. Before you apply, read can a company sell customer call recordings for AI training.

Concerns on record: the 2026 restructuring

In August 2026 ECO reported that Defined.ai was in a restructuring involving "a redução de 30% do número de trabalhadores", a cut of 30% of staff, mainly in Portugal, and that its chief operating and financial officers were leaving: "COO e CFO estão de saída da scaleup em processo de reestruturação" (ECO). Sources quoted by ECO said the cause "estaria uma quebra acentuada nas vendas", a sharp fall in sales. The company confirmed the departures and told ECO they had been planned before the restructuring, at the executives' own request and for personal reasons; ECO reports that it attributes the restructuring to "a necessidade de adaptar a estrutura à transformação a decorrer no setor tecnológico", the need to adapt to changes in the technology sector.

Three months later the company relaunched its marketplace and announced a program to bring in new data partners. A restructuring is not a sign that a company is unsound, and Defined.ai has paid partners for years. For a data owner the practical point is simple: a marketplace pays as datasets sell, so get payment timing, sales reporting and audit rights in writing, and ask what happens to your listing if the company changes direction.

What to check before you sign with Defined.ai

Defined.ai is one of the few marketplaces that openly invites company data, so it is worth comparing on the same terms as the others.

• Ask for your revenue share as a number, and how research-license sales at 20% of the commercial price are shared.
• Confirm whether the license to buyers is non-exclusive, which uses you approve and whether you can veto a buyer or use case.
• Ask who handles de-identification, and whether you review samples before they are shown to customers.
• Ask how often sales are reported and paid, and what audit rights you have over reported sales.
• Compare with other routes: data marketplaces compared, video data buyers compared, company data buyers compared and AI data companies.

Next step

A marketplace pays only when your dataset sells, so the size of the opportunity depends on demand for your data type. Before you list, check the buyer with how to vet an AI data buyer and compare what similar records have fetched in direct licenses.

Not sure whether a buyer or an offer is sound? Origin checks who the buyer is, what the license allows and how the price compares with published deals before anything is signed. Get a free estimate and a second opinion.
