How to Actually Get Hired

Yoeven studied at Imperial College London, one of the world's top engineering institutions, which is where his technical foundation developed before he moved into building full-time. His career before Interfaze is a pattern of shipping before asking for permission. He co-founded Stayr, a travel startup, before pivoting into JigsawStack, the developer API platform that became the direct predecessor to Interfaze. JigsawStack was not a pre-revenue bet: it had paying developer customers, processing billions of tokens monthly across healthcare, finance, and government use cases before YC came into the picture. Before founding, he and his team won the world's largest AI hackathon with a project called fly.travel, a real-time AI travel planning tool, which tells you something about how he approaches a new problem. He is prolific on GitHub, with 54 public repositories including an AI video search engine sitting at 627 stars, which he built as an open-source proof of concept. He is active on LinkedIn and X (@yoeven), posts regularly about developer tooling and AI infrastructure, and has made himself directly reachable at yoeven@jigsawstack.com. His public philosophy is plainly stated in his GitHub bio: "Building to my heart's content."

Harsha is the first named author on the Interfaze arXiv paper and the primary research engine behind the company's technical architecture. His background is a precise fit for what Interfaze is building: he holds an M.Sc. in Computer Science from Purdue University, with verified research activity on Google Scholar under his Purdue email, and his listed specialisms are Artificial Intelligence, Computer Vision, Natural Language Processing, and Reinforcement Learning. That quartet is not incidental. The Interfaze architecture requires exactly this cross-disciplinary depth: CNN/DNN perception models for OCR and visual extraction, NLP for classification and speech-to-text, and systems thinking for the controller layer that routes inputs to the right specialised model. Before Interfaze, Harsha was a founding member at JigsawStack, the developer API platform that Interfaze evolved from, where he led research. He also volunteers as a peer reviewer for Springer Nature's Journal of Progress in Artificial Intelligence, which is a meaningful signal about how seriously he takes research rigour: peer review is unpaid, unglamorous, and only done by people who care about the quality of the field's output. For a startup founder, it suggests someone who thinks carefully about what constitutes a valid claim, which matters when you are building a product that promises deterministic accuracy rather than probabilistic best-effort.
