Comparing Snorkel AI and Handshake AI

Snorkel and Handshake AI both have offerings around expert data for frontier AI.

Handshake's broader business began as a career network connecting students, professionals, educational institutions, and employers. Handshake AI extends that network into paid AI training work, expert evaluation, agent development, and enterprise AI services.

Snorkel was founded around data-centric AI technology and research. Its Expert Community is integrated into a broader system for developing expert-authored datasets, benchmarks, evaluations, environments, and specialized agents.

Both companies connect domain expertise with AI development, but their foundations and delivery models differ.

Core capabilities

What Snorkel develops

01

Agent and RL environments

Snorkel creates realistic environments in which agents must use tools, make decisions, complete multi-step tasks, respond to feedback, and produce verifiable outcomes.

02

Data-development technology

Snorkel's platform supports the creation, management, evaluation, and refinement of data across the AI lifecycle.

03

Specialized agents

Snorkel develops custom agents grounded in enterprise-specific data and tested against real workflow and performance requirements.

04

Expert-authored training and post-training data

Snorkel develops specialized datasets for supervised fine-tuning, preference learning, reinforcement learning, evaluation, and other model-development workflows.

05

Benchmarks and evaluations

Snorkel builds evaluation datasets, rubrics, evaluators, verifiers, and leaderboards that reveal where models and agents succeed or fail.

Why consider Snorkel AI?

Purpose-built for AI data development

Snorkel's technology, research, and delivery model are centered on developing the data and environments AI systems need to improve.

Embedded collaboration

Snorkel works directly with research, engineering, product, and domain teams to define target capabilities and develop the appropriate solution.

Research integrated with delivery

Research into benchmark design, evaluator calibration, failure analysis, and data quality informs the datasets and evaluation systems Snorkel develops.

Support from data to deployment

Engagements can extend from training data and evaluation to environment development and specialized agents.

Experts connected to a broader system

Snorkel's Expert Community provides domain knowledge, while its platform and research teams translate that knowledge into usable data, benchmarks, and environments.

Open benchmark leadership

In addition to leading the development of Senior SWE-Bench, Snorkel launched Open Benchmarks Grants with a $3 million commitment to support open-source datasets, benchmarks, and evaluation research.
