- Clerk
Participated · Series A · Mar 2023
Clerk builds developer tools for authentication, offering drop-in React components, APIs and admin dashboards that help apps authenticate users, detect malicious activity and manage user data. The company is primarily self-serve and prices based on monthly active users. Clerk claims about 1,300 paying customers and 16 million users under management for those customers. Management says it will expand its product beyond authentication into authorization to determine user permissions. Clerk plans a tight integration with Stripe Billing to map permissions to subscription plans as part of that authorization push. The company intends to grow headcount from 55 to 80 by the end of the year as it competes with rivals like Descope, Stytch and WorkOS. Clerk builds identity tooling purpose-built for front-end Jamstack and React developers. Rather than a traditional identity API, the company delivers prebuilt React components that let developers drop identity into applications in minutes. It offers a free plan plus three paid tiers—Hobby, Business and Enterprise—with differing features. The product has resonated with developers: Clerk grew 500% in five months and reports a million users under management. The company has 26 employees and is hiring roughly 15 more this year to scale engineering, sales and product. Founders Colin and Braden Sidoti are focused on capturing the front-end developer market as architectures shift toward componentized front ends. Clerk provides customizable, drop-in React components that let developers build sign-up/sign-in flows, user profiles, and security features without backend engineering. The product includes security essentials such as multi-factor authentication and active device management, and components like <UserProfile/> that handle 2FA and avatar upload. Although optimized for React frontends, Clerk’s auth solution is compatible with any backend or framework, aiding legacy applications transitioning to React. The company plans to expand its suite and create new tools to help B2B SaaS companies manage both user accounts and business accounts. Clerk’s longer-term vision is to bundle authentication, authorization, communications, billing and related services into cohesive React components. Notable users include Grafbase, Honeylove, and Blueground, and the company has been included in Netlify’s Jamstack Innovation Fund.
- ConductorOne
Participated · Series A · Jun 2022
ConductorOne provides an AI-native identity security platform that centralizes visibility, enforces least-privilege access controls, and automates the entire identity lifecycle across applications and infrastructure. Built from day one with AI, the platform unifies identity governance and administration, identity and access management, and privileged access management, replacing fragmented legacy tools. It connects to a broad set of systems through out-of-the-box connectors and uses automation to deliver a reported 95% reduction in IT effort for access requests, effectively doing the work of two full-time employees. ConductorOne currently manages millions of identities and is trusted by Fortune 500 and high-growth companies such as Zscaler, Ramp, DoorDash, DigitalOcean, and Instacart. As AI drives a 100x surge in identity counts, the company positions itself to address this complexity with scalable, AI-driven automation. With more than $100 million raised to date, ConductorOne plans to use new capital to accelerate product innovation—adding expanded AI automation, actionable analytics, and modern directory management—grow its team, and deepen enterprise adoption. The firm emphasizes a customer-obsessed culture and quick time-to-value, differentiating itself from legacy vendors.
