Is Sigma Worth It?

✅ Why Choose Sigma

• Extensive multilingual coverage with 60+ languages supported by native-speaking annotators who understand cultural context and regional nuance
• Strong specialization in generative AI evaluation and RLHF, positioning the company well for the current wave of LLM development
• Managed-service model with dedicated project teams provides higher consistency and quality control than self-serve crowd platforms
• Deep linguistic expertise goes beyond basic labeling, handling idiomatic expressions, cultural sensitivity, and domain-specific terminology

⚠️ Consider This

• Enterprise-only pricing with no published rates or self-serve tier means smaller teams and startups cannot easily assess cost or get started without a sales conversation
• Managed-service approach may result in longer onboarding and project setup times compared to self-serve annotation platforms like Labelbox or Label Studio
• Limited public documentation on platform capabilities, APIs, or integrations makes it difficult to evaluate technical fit before engaging with sales
• No free trial or freemium tier available, which creates a higher barrier to entry for teams that want to test the service on a small dataset first
