About Interfaze
JigsawStack (now rebranding as Interfaze) is an AI infrastructure startup providing a unified SDK and API suite of purpose-built small models designed to automate high-maintenance backend developer tasks including web scraping, OCR, translation, speech-to-text, and classification. The company's flagship evolution, Interfaze, is positioned as 'the world's first LLM built for deterministic developer tasks,' combining heterogeneous deep neural networks, small language models, and a context-construction layer into a single OpenAI-compatible API. Founded in January 2024, the company was accepted into Y Combinator's Spring 2026 batch and has processed over 10 million API requests since its beta launch.

Founders
Yoeven D Khemlani
Second-time founder and technologist who began as a game developer before moving into startup and financial services leadership. Was CTO and co-founder of Stayr/Staytion, a Southeast Asia prop-tech and travel startup that scaled to $1M ARR in Year 1 and $3M ARR in Year 2 before being acquired. After the exit, identified the gap in reliable AI backend tooling and founded JigsawStack in January 2024. Trained his own models from scratch after finding GPT-3 (20% accuracy) and Llama fine-tunes (50% accuracy) insufficient, eventually reaching 80%+ accuracy.
