Extend
Extend is an AI-native document processing platform that turns documents into high-quality, validated data. It handles extraction, classification, and splitting using large language models and vision-language models, and notably ships built-in tooling to continuously evaluate and improve performance, so teams can measure accuracy and tune it rather than treat the model as a black box. The company, based in New York, raised $17 million across its seed and Series A led by Innovation Endeavors, with Y Combinator, Homebrew, and angels including Scott Belsky and Guillermo Rauch participating, and says it reached several million dollars in ARR while becoming cash-flow positive. Customers such as Brex and Square use it to convert unstructured documents into production-ready data across finance, healthcare, and real estate. It is aimed at developers and operations teams, with usage-based, quote-driven pricing.

Streamlit
Open-source Python framework for building and sharing interactive data and AI/ML apps with minimal front-end code.
Langfuse
Langfuse is an open-source AI engineering platform for building and operating LLM applications. It brings together observability and tracing, evaluations, prompt management, datasets, an annotation workflow and a prompt playground, and integrates with OpenTelemetry, LangChain, the OpenAI SDK, LiteLLM and more. A Y Combinator (W23) company, it moved every product feature to the MIT license in 2025, so the only commercial pieces are thin enterprise-compliance add-ons such as SCIM, audit logs and project-level RBAC. The cloud free tier covers 50,000 units a month, with a $29/month Core plan for production traffic and higher tiers for longer retention and SOC 2/ISO reports. In January 2026 ClickHouse acquired Langfuse and publicly committed to keeping the MIT license and avoiding new pricing gates.
