MURATCAN KOYLAN
Member of Technical Staff @ Sully.ai
// BIO
Member of Technical Staff at Sully.ai, where he joined in 2026 as a Context Engineer working on clinical AI. Works on the AI Scribe and agent harnesses across medical specialties.
Came to AI from Communication Design (HCI) and seven years in B2B marketing. Most of his thinking and writing sits at the boundary between AI systems and the people meant to use them — clinicians at Sully, marketing strategists at 99Ravens, operators before that. Engineering and the non-technical side of that boundary are not separable jobs for him; they are one job seen from two angles.
Before Sully, Entrepreneur in Residence at Antler (Winter '26 Canada Residency, Jan–Feb 2026). Accepted with an auto-evolving context engineering skills MVP for coding agents. Withdrew after several LOIs to join Sully.
Before Antler, AI Agent Systems Manager at 99Ravens AI (2024–2026). Joined as the first AI hire (Prompt Designer) and moved into the systems role about three months in. Built the multi-agent platform on LangGraph/LangChain, the persona layer, an internal agent skills library, prompt engineering systems, and evaluation rubrics.
Seven years in B2B marketing before that: Insider, Tmob, Jonas Software. Communication Design (HCI) at Ozyegin University.
Early AI GTM builder before the category had settled language. Built Rootly's Clay-centered AI Demand Generation Engineer workflow for incident-signal monitoring, lead scoring, and real-time personalized outbound. Clay later featured Rootly's approach as a customer story. Also built BudBuddy AI, a playful early cannabis assistant publicly described by the oz. as the world's first A.I. budtender.
