What Plasticity does

Plasticity is a natural language processing (NLP) technology company founded in 2016 in San Francisco by Ajay Patel and Alex Sands. Its product portfolio centers on three cloud-hosted and on-premise APIs: Sapien Language Engine (low-level NLP tasks including named entity recognition, syntax dependency parsing, part-of-speech tagging, lemmatization, tokenization, spelling correction, coreference resolution, sentiment analysis, and open information extraction), Cortex Knowledge Graph (240+ million facts across 20+ million real-world entities, queryable in natural language, with weekly data refreshes and an option for custom document corpora), and Lingua Dialogue Engine (conversational interfaces with intent parsing, slot filling, and multi-turn dialogue management). The stack is built in C++ for throughput, claimed at 6,000 sentences per second. Plasticity also maintains the Disinformation Toolkit for government analysts and several open-source libraries (Magnitude, SuperSQLite, Coldbrew, and an official Python SDK).

Plasticity operates an API-first, usage-based go-to-market: developers start on a free tier per API and pay a cost-per-thousand-requests rate once usage caps are exceeded, with monthly billing, and corporate accounts can be linked to the AWS Marketplace. Enterprise and government customers are reached through a direct sales motion for on-premise deployments and custom integrations, billed under a separate statement of work that includes implementation, configuration, training, and advisory professional services. Customer segments span government and defense (intelligence, disinformation detection), commercial companies across technology, law, and medicine, and individual developers integrating NLP into applications.

Following a 2017 Y Combinator batch and a 2018 National Science Foundation SBIR award (the largest disclosed funding event at $224,679), Plasticity was acquired in October 2020 by Executive 1 Holding Company (EX1), a private AI/SaaS-focused holding company, and has since operated as a wholly owned subsidiary alongside EX1's HumanTouch LLC and CORASCloud Inc. The company's headquarters is now in McLean, Virginia. In March–April 2021, Plasticity disabled new public API signups and ended access for existing free apps, tightening the model toward enterprise and government contracts. Disclosed customers include the Wall Street Journal (social media sentiment analysis for political campaign coverage) and unnamed government agencies; total disclosed customers are described as "hundreds of organizations and thousands of developers" since 2016.

Core offering

Plasticity provides cloud-hosted and on-premise natural language processing APIs that allow developers, government agencies, and commercial customers to extract entities, relationships, and context from unstructured text, query a large knowledge graph of real-world facts, and build conversational interfaces. The core product suite comprises Sapien Language Engine (NLP tasks), Cortex Knowledge Graph (knowledge retrieval), and Lingua Dialogue Engine (conversational AI), delivered as JSON-based REST APIs with a Python SDK.

Product overview

Plasticity provides a suite of natural language processing products delivered as cloud-hosted or on-premise APIs. The core portfolio consists of three API products: Sapien Language Engine (low-level NLP tasks including NER, POS tagging, lemmatization, dependency parsing, coreference resolution, sentiment analysis, and open information extraction), Cortex Knowledge Graph (natural language queryable knowledge base of 240+ million real-world facts across 20+ million entities, plus custom document querying), and Lingua Dialogue Engine (intent classification, slot filling, and multi-turn conversation management for chatbots — currently in beta). These three APIs are available individually or bundled, with optional on-premise deployment and a Disinformation Toolkit add-on for government customers. Additionally, Plasticity maintains four open-source libraries (Magnitude, SuperSQLite, Coldbrew, Plasticity Python) available on GitHub for the developer community.
