Team
Four founders, one product team
We have worked together for years across design, engineering, data, and product. Together we cover the entire path from a business opportunity to software people actually use, and we do the work ourselves.
Jeff Meyer
Co-founder · Product & Client Relationships
Jeff leads how Fourthcraft works with clients: understanding the business problem, shaping the product, and keeping delivery tied to outcomes that matter.
Focus: Market access, discovery, business case, product strategy, and commercial direction.
Ersan Sano
Co-founder · Engineering & Operations
Ersan owns how software gets built and shipped: system architecture, application development, cloud infrastructure, and the operational discipline that keeps production stable.
Focus: Architecture, application development, infrastructure, deployment, and delivery.
Eilert Hjelmeseth
Co-founder · Engineering & Data
Eilert leads the data side of every engagement: databases, pipelines, integrations, analytics, and the evaluation and governance that make data trustworthy enough to build on.
Focus: Data systems, pipelines, retrieval, analytics, evaluation, and governance.
John Chanthana
Co-founder · Design & User Experience
John is responsible for the product being something people actually use: user research, interface and workflow design, and the details that turn a working system into an adopted one.
Focus: Research, experience design, usability, workflow design, and adoption.
