What Rapidata does
Rapidata is a Zurich-based, privately held AI infrastructure company founded in 2023 by CEO Jason Corkill. It provides a human-verified data labeling and processing platform that enables AI developers to collect on-demand human feedback at global scale, compressing feedback cycles from weeks or months to hours or days. The platform serves AI companies, ML engineers, and AI researchers building generative AI systems, with primary use cases in RLHF, model fine-tuning, and evaluation.
The core product is the Rapidata Platform, accessed via a Python SDK and REST API at app.rapidata.ai. It supports multiple modalities (image, video, audio, text, multimodal) and a suite of order types — classification, compare, ranking, locate, draw, free text, select words, and timestamp — built around an Elo-based pairwise ranking engine. Quality control is provided through Validation Sets (known-answer tasks for annotator qualification) and cost is optimized via Confidence Stopping (early termination at a configured confidence threshold). Model Ranking Insights (MRI) is a benchmarking sub-product that supports leaderboards across evaluation criteria, and Ranking Flows enables lightweight continuous evaluation without full job overhead.
The business operates an API-first, product-led growth motion targeting a horizontal customer base of AI developers. Distribution runs entirely through digital channels — pip-installable SDK, open-source GitHub repository, self-serve dashboard, and developer documentation at docs.rapidata.ai — with no disclosed resellers or physical channels. Revenue mechanics are usage-based via a credit system, although public pricing is not disclosed. The company has raised approximately CHF 1.5M (2023, BlueYard-led) plus an $8.5M seed round in February 2026 co-led by Canaan Partners and IA Ventures, with participation from Acequia Capital and BlueYard. Earlier Swiss ecosystem support includes Venture Kick grants, Founderful Campus, Venture Leaders, and Innosuisse funding.

Rapidata competitors and assessment
Company assessmentEmerging players
- Snorkel AI: Snorkel AI focuses on programmatic and data-centric AI, including labeling functions and weak supervision for model training. It is comparable to Rapidata as an AI-data infrastructure peer, though it emphasizes automated/programmatic labeling rather than large-scale human feedback collection.
Direct peers
- SuperAnnotate: SuperAnnotate provides an AI annotation platform with managed labeling services for computer vision and NLP use cases. It overlaps with Rapidata on annotation tooling and AI-training data preparation, with similar SDK/integrations and target buyer (ML engineers and AI teams).
- Surge AI: Surge AI is a US-based data-labeling platform purpose-built for RLHF and human-preference evaluation on foundation models. It directly competes with Rapidata on the same AI-developer buyer, similar task types (compare, rank, classify), and a similar emphasis on quality crowd work for frontier-model labs.
- Labelbox: Labelbox provides a data-labeling platform with tooling for classification, comparison, segmentation, and ranking workflows used by AI teams. It serves the same AI-developer and ML-engineer personas as Rapidata, with overlapping SDK/API distribution and a focus on labeling workflows for model training.
- Encord: Encord offers an annotation and data-engineering platform for multimodal AI, supporting images, video, and audio labeling workflows for ML teams. It targets the same AI-developer buyer as Rapidata with comparable task types and SDK-style developer experience, though with less emphasis on RLHF and preference evaluation.
- Toloka AI: Toloka AI operates a crowdsourcing platform for data labeling and RLHF-style human evaluation, with a globally distributed participant network similar to Rapidata's. It targets the same AI-developer persona for preference data, ranking, and classification tasks, though with roots in Eastern European and broader emerging-market crowds.
Broad incumbents
- Appen: Appen is a long-established data-annotation provider offering global crowd workforce services for AI training data across text, image, audio, and video. It serves as a broad incumbent comparable to Rapidata in customer base (enterprise AI teams) and service scope, but with traditional outsourced-service delivery rather than an API-first SDK model.
- Scale AI: Scale AI is the dominant incumbent in data labeling and evaluation for AI, offering RLHF, annotation, evaluation, and benchmark services across modalities. It overlaps Rapidata on RLHF and model evaluation but operates at significantly greater scale and breadth across government, enterprise, and frontier-model customers.
Regional players
- Sama: Sama provides ethically sourced data annotation services primarily for computer-vision AI, with operations concentrated in East Africa and serving North American enterprise customers. It is comparable to Rapidata in offering human-verified training data, but its delivery model (managed services, impact sourcing) differs from Rapidata's API-first PLG approach.
- CloudFactory: CloudFactory provides managed AI data-labeling workforces primarily for social-impact and enterprise customers across Asia and Africa. It overlaps with Rapidata in offering human-verified training data, but uses a managed-workforce delivery model rather than an SDK/API-first, real-time platform.
