# PokitDok: Healthcare's API-First Data Platform
PokitDok is a healthcare software platform that streamlines business processes by providing secure, unified access to healthcare data through cloud-based APIs.[1] Founded in 2011 and headquartered in San Mateo, California, the company built a comprehensive developer platform that connects healthcare organizations, payers, and providers through standardized API endpoints and blockchain technology.[2][3]
PokitDok addresses a fundamental fragmentation problem in healthcare: the inability of disparate systems to communicate efficiently. The company provides 30+ API endpoints that facilitate critical healthcare transactions including eligibility checks, claims submissions, appointment scheduling, payment optimization, patient identity management, and pharmacy benefits management.[3] Rather than building end-user applications, PokitDok operates as infrastructure—over 1,000 third-party enterprise applications run on its platform, built by healthcare organizations, digital health companies, and business process outsourcing consultants.[3]
The platform connects with more than 500 health insurers and payers, representing 93 percent of US insurance members, enabling seamless data exchange across the healthcare ecosystem.[3] This network effect creates significant switching costs and positions PokitDok as a critical middleware layer between providers, payers, and consumers.
PokitDok emerged in 2011 during the early stages of healthcare IT modernization, when electronic health records and digital workflows were still nascent.[1] The company's founding vision centered on using APIs and later blockchain technology to solve the "high-friction environment" created by legacy clearinghouses and electronic medical records systems.[4]
A pivotal moment came in 2015 with an oversubscribed Series B round led by Lemhi Ventures, which brought the company to $48 million in total funding.[3] This capital fueled significant expansion: the company doubled headcount, launched on AWS Marketplace, entered the pharmacy business, and introduced production-ready blockchain solutions to healthcare.[3] In 2016, McKesson Ventures—the corporate venture arm of pharmaceutical distributor and health IT vendor McKesson—made a strategic investment, signaling enterprise validation and opening doors within the healthcare establishment.[2]
PokitDok rode two major waves: the healthcare IT modernization trend and the blockchain hype cycle of the mid-2010s. The company's timing was strategic—healthcare organizations faced mounting pressure to digitize workflows, yet legacy systems created massive interoperability barriers. Blockchain offered a compelling narrative for solving trust and transparency problems without requiring centralized intermediaries.
The company's influence extended beyond its direct customer base. By demonstrating that blockchain could solve real healthcare problems (claims processing, identity management, pharmacy supply chains), PokitDok helped legitimize blockchain applications in enterprise healthcare at a time when many dismissed the technology as speculative.[4] The platform also influenced how healthcare companies thought about APIs and developer ecosystems, pushing the industry toward more open, composable architectures.
PokitDok's trajectory shifted in December 2018 when Change Healthcare—a health IT company majority-owned by McKesson—acquired PokitDok's intellectual property and assets.[2] Rather than remaining independent, PokitDok's technology was integrated into Change Healthcare's Intelligent Healthcare Network, combining PokitDok's blockchain expertise and API marketplace with Change's broader healthcare infrastructure.[2][5]
This acquisition reflected both validation and consolidation: PokitDok had proven the value of its platform, but the fragmented healthcare IT market favored larger, integrated players with distribution reach. The deal allowed PokitDok's founders and team to scale impact through a larger organization while providing Change Healthcare with cutting-edge blockchain and API capabilities.[5]
Looking forward, PokitDok's legacy lies in demonstrating that healthcare's interoperability problem requires both technical innovation (APIs, blockchain) and network effects (trading partner agreements). As healthcare continues its digital transformation and value-based care models demand real-time data sharing, the architectural principles PokitDok pioneered—decentralized identity, smart contract automation, transparent transaction records—remain relevant regardless of whether they operate under the PokitDok brand or within larger healthcare platforms.
PokitDok has raised $82.8M across 6 funding rounds. Most recently, it raised $5.0M Other Equity in March 2017.
