Oumi Launches Platform for Companies to Build and Own AI Models

Companies have moved quickly to adopt general-purpose models from OpenAI, Anthropic and Google, but renting access can expose them to rising usage costs, vendor dependence and data-security concerns. Such models may also underperform on narrow business tasks. Seattle-based Oumi, founded in 2024 by former Google, Microsoft and Apple engineers, argues that companies can build a more durable advantage by owning specialized models, their weights and the operational data used to improve them.

Oumi launched its Compounding AI Factory on March 31, 2026, automating data generation, fine-tuning, evaluation, deployment and retraining from production feedback. Pricing starts at $25 per organization a month, excluding usage-based training and evaluation charges. Oumi said Divisions Maintenance Group lifted invoice-validation accuracy to 99% from 72% using a model with fewer than 1 billion parameters. The startup had raised a $10 million seed round on January 29, 2025, led by Venrock and Obvious Ventures.
