## clickworker

clickworker is a data-services company that turns business data projects into structured microtasks carried out by a global crowd. Companies define a task — collecting shelf photos, labeling images, verifying addresses, running surveys, testing an app — and clickworker recruits, briefs and quality-checks the workers who complete it. The crowd numbers more than 10 million registered freelancers across 136 countries.

The core offering is AI training data: image, video, audio and text datasets with human-powered labeling, annotation and validation, delivered in cooperation with parent company LXT. Around that sit adjacent services such as surveys with a verified respondent pool, store checks and display audits at the point of sale, tagging and sentiment analysis, crowdtesting for websites and apps, list building, and SEO copywriting.

Engagements can be self-service, fully managed or delivered through an API and iframe integration. clickworker emphasizes its 20+ years of microtask experience, ISO 27001 certification and GDPR compliance, and works with clients such as OTTO, Bosch and Tennis-Point on large-scale data collection and evaluation projects.

**Pricing & Plans:** clickworker quotes project prices rather than publishing list rates; cost depends on task type, volume, target geography and quality requirements. A self-service option and a managed service are both available, and Clickworkers are paid per completed task.

- **AI training data at scale:** Custom image, video, audio and text datasets with human labeling, annotation and validation, delivered with parent company LXT.
- **Global crowd of 10M+ Clickworkers:** Registered freelancers in 136 countries fill microtasks through web, Android and iOS apps, with flexible scaling up or down.
- **Survey and market research services:** An all-in-one survey tool plus access to a verified respondent pool for external studies and targeted insights.
- **Store checks and crowdtesting:** Real-time point-of-sale data collection, display audits, mystery checks, and usability testing for websites, apps and games.
- **Managed, self-service and API delivery:** Choose a fully managed project, run tasks yourself, or integrate crowd workflows through API and iframe form options.

**Strengths:** Enormous, geographically diverse crowd that can scale projects up or down quickly; Covers the full data pipeline from collection through annotation and validation; ISO 27001 certified and GDPR compliant with documented quality assurance; Multiple engagement models: managed, self-service, API and iframe

**Limitations:** Pricing is quote-based, so smaller projects may struggle to get transparent costs; Quality depends on task design and briefing, which the client must invest effort in; Not a plug-and-play AI API — it is a services business requiring project scoping

## Grably

Grably is a multi-modal human interaction data research company. Rather than selling generic web scrapes, it positions itself as a lab that captures and models how people act, sense, decide, and communicate, then packages that into structured datasets for AI developers. Its site highlights backing from Techstars and partnerships with leading AI labs and technology companies.

The company organizes its offering into suites for image, video, audio, code, and text, alongside a catalogue of multi-modal conversational data. Publicly described assets include billions of sequential messages in more than 100 languages, thousands of hours of labelled sports footage, and tens of millions of medical studies. Each dataset is aimed at a specific modelling need, from LLM pretraining and multilingual coverage to embodied AI, temporal video understanding, speech, and document intelligence.

Grably also builds custom datasets for clients with niche goals, aligning anonymization, filtering, and delivery formats to internal research, legal, and infrastructure requirements. Delivery timelines vary by modality, and pricing is scoped per engagement, so prospective buyers discuss requirements directly with the team. The overall pitch is data quality and human-centred signal, not volume alone.

**Pricing & Plans:** Pricing is contact-based. Each dataset or custom project is quoted according to scope, modalities, and delivery requirements.

- **Multi-modal data suites:** Datasets covering image, video, audio, code, text, and conversational interaction for varied model-training needs.
- **Custom dataset design:** Buyer-scoped datasets with configurable anonymization, filtering, modalities, and delivery formats.
- **Multilingual coverage:** Conversational and text data spanning 100+ languages, including low-resource and underrepresented regions.
- **Structured, annotated content:** Signals that are aligned, annotated, and validated for cross-modality and scientific consistency.
- **Domain-specific corpora:** Specialized datasets for sports, medical records, documents, scientific literature, and code.

**Strengths:** Broad multi-modal and multilingual dataset catalogue; Custom dataset design with configurable anonymization; Enterprise and research-lab oriented delivery; Backed by a recognised accelerator program

**Limitations:** No self-serve pricing or instant purchase flow; Dataset access requires a sales conversation; Delivery timelines for rich modalities can span weeks
