Defined.ai: Trusted Platform Providing Bias‑Free Training Data Via Neevo Crowdsourcing And Professional AI Project Services

The Silicon Review

In the race to build smarter machines, few companies are asking the harder question: what kind of intelligence are we building—and who does it serve? Defined.ai was founded to answer that challenge. As one of the world’s leading providers of ethically sourced, high-quality AI training data, Defined.ai empowers organizations to build inclusive, responsible, and high-performing AI systems.

From global corporations to startups, thousands of clients rely on Defined.ai to supply voice, vision, text, and multimodal datasets that reflect the richness of human experience—across language, culture, geography, and identity. Their data powers everything from voice assistants to diagnostic models, ensuring the AI we use every day is more accurate, less biased, and genuinely helpful.

A Vision Grounded in Responsible Innovation

Defined.ai began as DefinedCrowd in 2015, founded by Dr. Daniela Braga, a linguist and machine learning expert who witnessed firsthand the lack of quality and ethical rigor in AI data. What started as a smarter crowdsourcing solution quickly evolved into a robust AI data infrastructure company. Today, Defined.ai operates from offices in Seattle, Lisbon, Porto, and Tokyo, serving clients across industries like finance, healthcare, retail, and public sector.

The company’s evolution reflects a commitment to more than just scale—it reflects a belief that how data is collected, labeled, and managed matters as much as the algorithms that consume it. Defined.ai’s ethical framework is built into every step of their pipeline: informed contributor consent, GDPR/CCPA compliance, rigorous QA processes, and full traceability.

The rebrand from DefinedCrowd to Defined.ai in 2022 marked a pivotal shift—from a data provider to an end-to-end enabler of ethical, performant AI. With a product suite that now includes data, workflows, tools, and consulting, Defined.ai has positioned itself as a foundational player in building trustworthy AI systems at scale.

Data That Does More: Scalable Solutions Across the AI Lifecycle

Curated Data Marketplace

The Defined.ai Marketplace offers one of the largest collections of pre-labeled datasets for AI, covering voice, image, text, and video. It includes:

Multilingual speech recordings for voice assistants and speech recognition
Sentiment and intent-labeled text for chatbots and NLP engines
Visual data for facial recognition, diagnostics, or surveillance models
Specialized datasets for underrepresented languages and demographics

Each dataset is vetted for quality, diversity, and traceability—ensuring not just performance, but integrity.

Custom Data Collection & Annotation

When off-the-shelf isn’t enough, Defined.ai delivers customized data pipelines. Whether it’s a 10,000-speaker speech corpus in Arabic, or a medical annotation project involving radiology images, Defined.ai manages the full cycle:

Task design & pilot testing
Contributor selection and training
Data collection and expert-level annotation
Real-time monitoring, QA, and client feedback integration

This bespoke model allows enterprises to train their models on exactly the data they need—with precision, scalability, and peace of mind.

Neevo Contributor Platform

Powering Defined.ai’s annotation capabilities is Neevo—a crowdsourcing platform with over 500,000 global contributors. Neevo contributors tag, annotate, transcribe, and validate data in over 70 languages. Each task is vetted for fairness, contributors are paid fairly, and audits are in place to ensure consistency.

Defined.ai’s proprietary tools ensure that tasks are transparent, contributors are protected, and outputs meet enterprise-grade standards—turning global labor into equitable, accountable AI development.

Security, Compliance & Ethical Governance

In a world where data misuse can lead to lawsuits, bias, or reputational damage, Defined.ai makes ethics a competitive advantage. The company is ISO 27001 and ISO 27701 certified, ensuring that privacy and security are not afterthoughts—they’re foundational.

Additionally, the company’s datasets and workflows are aligned with major global regulations, including GDPR and CCPA. Clients receive data that is not only high-quality, but fully traceable, auditable, and compliant.

Why Defined.ai Is More Than a Data Vendor

Most AI projects fail not because of the algorithm, but because of the data. Poor quality, lack of diversity, or legal risk can undermine even the most sophisticated models. Defined.ai offers a solution that blends performance with principles.

Clients choose Defined.ai because they need more than just volume—they need precision. They need clarity about where their data came from, how it was labeled, and whether it’s legally safe to use. With Defined.ai, they get all of that, wrapped in a platform that’s scalable, secure, and supported by an expert team.

The company isn’t just enabling AI; it’s shaping the kind of AI we want in the world—ethical, effective, and inclusive by design.
