Arcline

Arcline is a Y Combinator-backed company that startup legal work handled by elite lawyers & same-day turnaround. The company participated in the Winter 2026 batch of Y Combinator.

Arcline provides AI-native legal services for startups, with same-day turnaround & elite lawyers in the loop. Our AI does 80% of the work, so startups pay elite lawyers only for the final 20%.

Arcline's founder Pamir, ex-outside counsel to OpenAI, saw the same issues on repeat when lawyers were serving startups: simple legal work took weeks, pricing was opaque, and lawyers kept starting from scratch instead of using AI.

Arcline was part of Y Combinator's Winter 2026 cohort, has a team of approximately 5 employees, and is actively operating.
