Casium is a Seattle-based legal technology startup using artificial intelligence to streamline the work visa application process, helping US employers hire and retain global talent faster. The company was spun out of the AI2 Incubator (the startup studio affiliated with the Allen Institute for AI) in April 2024 and tackles a workflow that is notoriously slow, paperwork-intensive and error-prone: assembling, drafting and filing employment-based immigration petitions.
The platform automates much of the administrative burden in visa case preparation — gathering inputs, drafting filings and assembling supporting evidence — while keeping licensed attorneys in the loop to ensure accuracy and compliance. By compressing the manual work that typically consumes immigration paralegals and lawyers, Casium aims to shorten turnaround times and reduce the friction that makes the US immigration system feel, in the founder's words, exhausting and career-limiting for the workers who depend on it.
Casium is led by founder and CEO Priyanka Kulkarni, a former Microsoft scientist and entrepreneur-in-residence at the AI2 Incubator. Her background in applied machine learning shaped a product that treats immigration filings as a structured data and document-generation problem rather than a purely manual legal exercise.
In October 2025 Casium announced a $5 million seed round led by San Francisco-based Maverick Ventures, with participation from Seattle's AI2 Incubator, GTMfund, Success Venture Partners and angel Jake Heller, the co-founder of Casetext (acquired by Thomson Reuters). The Casetext pedigree among its backers is notable given Casetext's status as one of legal AI's marquee outcomes.
Casium positions itself within a fast-emerging wave of immigration-tech startups that, after years of experimentation, are now raising real money and showing real traction with employer customers. Its bet is that a blend of AI automation and attorney oversight can modernize a visa process that has not kept pace with the demands of global hiring.
