Onehouse is a Menlo Park-based technology company founded in 2021 that builds a fully managed, cloud-native data lakehouse platform centered on open-source technologies like Apache Hudi, Apache Iceberg, and Delta Lake.[1][2][3] It serves data-intensive sectors including analytics, reporting, data science, machine learning, and generative AI (GenAI) by providing seamless data ingestion, continuous pipelines, automatic optimizations, and universal query compatibility across clouds and engines, enabling a single source of truth without vendor lock-in.[1][2] The platform eliminates manual infrastructure hassles, supports real-time streaming, smart ETL, and serverless compute, helping enterprises like those in energy and tech build scalable data products efficiently; it has raised $68M in funding, including a $35M round, signaling strong growth momentum amid rising demand for open data architectures.[2][4]
Onehouse emerged from the need to simplify massive-scale data management, pioneered by founder Vinoth Chandar, the creator and PMC chair of Apache Hudi during his time at Uber, where he addressed speed and scale challenges for Uber's data platform after experiences at Oracle, LinkedIn, and Confluent.[3] Joined by Kyle Weller, former Product lead at Azure Databricks who scaled lakehouse adoption and saw the pains of DIY infrastructure, and Nilesh Mahajan, a founding engineer from Uber who built core platform services like real-time messaging, the team launched in 2021 to deliver a managed service blending warehouse usability with data lake scale.[3][4] Early traction built on Hudi's open-source success, evolving into a universal lakehouse with interoperability projects like OneTable (backed by Microsoft and Google) and recent launches like 'Open Engines' in April 2025.[1][4]
Onehouse rides the lakehouse trend, merging data lakes' scale with warehouses' reliability to power AI/ML/GenAI workloads amid exploding data volumes and multi-cloud environments.[1][2] Timing is ideal as enterprises shift from proprietary systems (e.g., Snowflake, Databricks) to open formats for cost control and flexibility, amplified by open-source momentum from Hudi/Iceberg and interoperability efforts like OneTable involving Microsoft/Google.[4] Market forces like real-time analytics demands, regulatory compliance needs, and GenAI's data hunger favor Onehouse's automated, vendor-agnostic platform, positioning it to influence the ecosystem by accelerating open compute adoption and reducing DIY lakehouse barriers for data teams.[1][2][3]
Onehouse is primed to capture share in the $50B+ data management market by expanding 'Open Engines' capabilities and universal lakehouse features, potentially deepening integrations with rising AI platforms.[1][4] Trends like agentic AI, federated learning, and edge-to-cloud data flows will amplify demand for its real-time, optimized pipelines, while further open-source contributions could solidify its leadership. As the shift to open data architectures accelerates, Onehouse's Hudi roots and funding firepower position it to redefine scalable analytics, empowering more innovators to own their data bedrock without compromises—echoing its mission to make lakehouses as easy as warehouses from day one.[2][3]
