Launch HN: Vela (YC W26) – AI for complex scheduling

Hi HN! We're Gobhanu and Saatvik (brothers), building Vela ( https://tryvela.ai ) - AI agents that handle multi-party, multi-channel scheduling. Scheduling is a constraint satisfaction problem disguised as email! It’s easy when it’s two people, one timezone, one channel. But it becomes a constraint satisfaction problem when inputs are unstructured natural language across multiple communication channels, constraints change mid-solve, and the objective function includes social dynamics that don't exist formally anywhere. What if scheduling just happened? For example: a recruiter sends one message, and every interview across five candidates, three hiring managers, and two time zones gets booked, confirmed, and updated automatically. No links, no back-and-forth, no one spending hours with 20 emails. Everyone just gets the right invite at the right time, on whatever channel they actually use. That's what we built Vela to do. You loop in Vela into your emails, SMS, WhatsApp, Slack, phone or
