# SafetyKit **Source:** https://geo.sig.ai/brands/safetykit **Vertical:** Security **Subcategory:** General **Tier:** Emerging **Website:** safetykit.com **Last Updated:** 2026-04-14 ## Summary SF YC S23 AI trust and safety automation for Patreon, Eventbrite, Upwork, Character.ai; $27.5M total ($27M First Round/Ribbit Series A Apr 2025) replacing manual risk reviews with AI agents for $10B+ marketplace and $100B+ payments platforms. ## Company Overview SafetyKit is a San Francisco-based AI trust and safety automation platform — backed by Y Combinator (S23) with $27.5 million in total funding including a $27 million Series A in April 2025 led by First Round Capital and Ribbit Capital with Y Combinator — providing online marketplace, payments, and creator economy platforms with AI agents that automate risk reviews, fraud detection, onboarding investigations, and content safety decisions, replacing the manual human review workflows that trust and safety teams currently handle for every new seller, merchant, or creator joining a platform. Founded in 2023 by David Graunke, Steven Guichard, and Alex Rosenblatt (alumni of Stripe, Meta, Netflix, MIT, and Princeton), SafetyKit serves customers including Patreon, Eventbrite, Upwork, Character.ai, Substack, and Faire, plus a $10B+ marketplace and a $100B+ payments company. SafetyKit's AI trust and safety agents address the scaling challenge that every marketplace and payments platform faces as it grows: reviewing each new merchant, seller, or creator for fraud risk, policy compliance, and identity verification requires trained human reviewers who evaluate application data, business documentation, and behavioral signals — a process that becomes a bottleneck when platform growth exceeds the capacity of the trust and safety team. SafetyKit's AI agents automate the investigation workflows (pulling and correlating data from business registration databases, identity verification APIs, payment risk signals, and behavioral analytics) to generate risk assessments and automated decisions for routine cases — escalating only genuinely ambiguous or high-stakes cases to human reviewers. The result is faster merchant onboarding (reducing the days-long manual review queue to automated decisions in minutes) and lower trust and safety operational costs without increasing fraud rates. In 2025, SafetyKit competes in the trust and safety automation, fraud prevention, and marketplace risk management market with Sardine (fintech fraud prevention, $75M raised), Sift (digital trust and safety, $200M raised at $1B valuation), and Unit21 (AML and fraud operations, $100M raised) for marketplace and payments platform trust and safety automation adoption. First Round Capital and Ribbit Capital's Series A co-leadership reflects the combination of enterprise SaaS investing expertise (First Round) and fintech risk management conviction (Ribbit) that a trust and safety automation platform requires. The $27M Series A at only 18 months post-founding demonstrates the enterprise revenue traction and customer validation from Patreon, Eventbrite, and Upwork deployments. The 2025 strategy focuses on expanding the enterprise marketplace customer base (platforms with $1B+ gross merchandise value where trust and safety cost reduction has the highest ROI), building the GenAI investigation reasoning capabilities for complex multi-party fraud schemes, and deepening the payment network risk signal integrations. ## Frequently Asked Questions ### What is SafetyKit?
