Aaron Stillwell is a Field Engineering Lead with 11 years’ experience helping technical SaaS businesses scale from product-market fit toward public-market readiness, most recently joining Neuralk AI as the first customer-facing technical hire. He built and led pre- and post-sales field engineering organizations at CircleCI across EMEA, NAMER and Japan, directly influencing the company’s largest high-seven-figure deal and redesigning delivery models to convert PoCs into sizable revenue. Aaron combines hands-on engineering chops (early solutions engineer roles, CI performance work, and cloud migrations) with commercial insight—uncovering advantages like per-second billing that saved customers hundreds of thousands. He’s skilled at turning technical complexity into repeatable GTM plays, hiring and retaining teams through hypergrowth, and aligning engineering outcomes with customer value. Based in London and steeped in developer-first product environments, he brings a pragmatic operator’s mindset to early-stage, high-impact roles.
