PSPDFKit (Now Nutrient) — Document SDK Platform
PSPDFKit is now Nutrient
PSPDFKit rebranded to Nutrient in 2024. See the Nutrient vendor page for current product information, features, and capabilities.
What is PSPDFKit
Founded in 2011 by Peter Steinberger, PSPDFKit established itself as a leading PDF technology provider for mobile and web developers. The company built its reputation on high-fidelity PDF rendering, annotation, and editing SDKs across iOS, Android, and JavaScript platforms.
Following a €100M investment from Insight Partners in 2021, PSPDFKit expanded through acquisitions of Muhimbi, ORPALIS, Aquaforest, and Integrify. In 2024, the company unified these products under the Nutrient brand, reflecting its evolution from a PDF SDK into a comprehensive document processing platform.
The PSPDFKit processor was sold for approximately $119 million, with Steinberger stepping away from operations for three years. In early 2026, Steinberger returned to active development, launching OpenClaw, an open-source AI assistant that gained over 60,000 GitHub stars within days — demonstrating the founder's pivot from document processing to AI automation.
