YC P26 Spin Party
YC Spring Kickoff at SPIN SF 🏓
Welcome to the batch! Hosted by Rippling, MongoDB, Fondo, Arga Labs, and Respan — Join your fellow YC founders for an evening of ping pong, great food and drinks, and meaningful connections at SPIN San Francisco.
We’re kicking things off with an opportunity to meet your batch mates, swap stories, and start building the relationships that will define your YC journey. This is your chance to connect with the incredible founders building alongside you.
Fondo (YC W18): Accounting on autopilot for 1,000+ startups. Get your bookkeeping done, taxes filed, and up to $500k back from the IRS. FREE TaxPass when you signup for monthly bookkeeping (save $1,950+).
Respan (formerly Keywords AI) gives teams a unified control plane to trace and evaluate agent behavior without guesswork, automatically surface issues, and fix what breaks faster. Respan connects production observability, automated and human-in-the-loop evaluations, and an adaptive AI gateway to close the loop between detection, decision, and action - so agents improve continuously in production.
Arga Labs (YC P26) provides infrastructure for teams to validate their code or agents. Deploy your app/agent into a sandbox with fully-functional twins (like Slack, Stripe, GDocs) that work out-of-the-box, without changing a single line of code. YC companies are saving engineer hours from manual QA & catching edge-case bugs with Arga. Learn more at www.argalabs.com.
