What Memberstack does

Memberstack is a no-code membership platform that adds authentication, Stripe payments, and gated content to any website. The core product is a drop-in JavaScript solution that uses data attributes for no-code integration with Webflow, a native plugin for WordPress, a DOM Package SDK for React/Svelte/Vue, and script injection for custom and AI-built sites; a server-side Admin REST API provides full programmatic control. Feature modules include authentication (email/password, one-time codes, social logins including Google, Facebook, GitHub, LinkedIn, Spotify, Dribbble, and OpenID Connect SSO), Stripe-powered subscription billing and one-time charges in 135+ currencies with Apple Pay, Google Pay, and iDEAL, content gating at the page/section/element level, custom member fields with JSON storage, Data Tables for additional record types, and an Email Campaigns module (Beta). The platform is SOC 2 Type 1 certified, GDPR and CCPA compliant, and is a Stripe Verified Partner with $200M+ processed, 10M+ member accounts managed, and 50K+ sites launched to date.

The business model is product-led and self-serve with a "free until launch" wedge. Users sign up without a credit card, build on free development tiers, and only begin paying once their site goes live. Revenue is generated from a 2–4% transaction fee on payments processed plus standard Stripe fees, supplemented by subscription plan tiers that scale with member allowances (paid plans begin at $29/month). Customer segments span solo creators and no-code builders using Webflow, Webflow agencies (Relume, Finsweet, Flowbase, Refokus, Whiteboard, Brandweld), funded startups migrating from Webflow to React, and enterprise-adjacent end customers whose membership sites are built using Memberstack — including Stanford, Deloitte, Intuit, Slack, American Airlines, Amazon, and Salesforce as end brands served via customer-built sites.

Memberstack was founded in 2018 by Duncan Hamra and Tyler Bell, is incorporated in the United States as Memberstack Inc., and is headquartered in Williamsburg. The company raised a single disclosed $2.0M seed round in October 2020 led by Gradient with participation from Y Combinator, 1517 Fund, Tiny Capital, Village Global, Liquid 2 Ventures, and Leblon Capital, and has since operated without disclosed follow-on funding, suggesting a bootstrapped or near-cash-flow-positive posture. The company is privately held, employs 11–50 people, and has expanded its product surface in 2025 with Email Campaigns (Beta) and an MCP Server for AI tools (Claude, Cursor).

Direct peers

• Outseta: All-in-one membership platform offering auth, subscriptions, CRM, and email for membership sites. Memberstack explicitly publishes a head-to-head comparison (Memberstack vs Outseta) and Outseta's pricing is referenced in Memberstack's own materials — closest direct competitor in the no-code membership SaaS category.
• MemberSpace: Drop-in membership plugin for websites, competing directly with Memberstack's Webflow/WordPress positioning. Memberstack publishes a 'Memberstack vs MemberSpace' alternative page — direct overlap in target customer, feature set, and go-to-market.
• MemberPress: Leading WordPress membership plugin offering subscriptions, content gating, and online courses. Memberstack's WordPress integration overlaps directly with MemberPress's feature set and SMB/creator customer base.
• Wishlist Member: Long-standing WordPress membership plugin providing content gating, subscription management, and member directories. Comparable feature surface and SMB customer base to Memberstack's WordPress product line.
• Kajabi: All-in-one platform for creators to sell courses, memberships, and digital products. Competes with Memberstack at the higher end of the no-code membership market, particularly for creators and SMBs launching paid communities.
• Teachable: Platform for selling online courses and memberships with built-in payments and gated content. Overlaps with Memberstack-powered course businesses such as Master The Handpan (24,000+ course purchases) and similar education use cases.
• Circle: Community platform with memberships, gated content, and Stripe-powered subscriptions. Comparable to Memberstack for the paid-community and creator-economy segment, though Circle is more opinionated as a hosted community experience.

Broad incumbents

• Webflow Memberships: Native memberships feature shipped by Webflow directly into its site-building platform. As the host platform, Webflow bundles auth, payments, and gating with no third-party fee — a built-in substitute for Memberstack on its most important distribution surface.
• Auth0: Broad authentication-as-a-service platform used by enterprise developers. Overlaps with Memberstack's authentication feature layer at the developer/enterprise end, though Auth0 targets engineering teams rather than no-code builders.
• Stripe: Underlying payment processor Memberstack is built on (and a Stripe Verified Partner with $200M+ processed). While not a direct competitor, Stripe's continued expansion into subscriptions, billing, and identity could over time substitute for parts of Memberstack's stack at the high end.
