Member portal development
Authenticated dashboards where members manage their profile, access benefits, view event history, and renew. Built to your brand and workflows, not a vendor template.
Associations · Communities · Subscription products
Membership platforms built to retain, not just enroll.
We build custom membership platforms for professional associations, online communities, and subscription products. The work covers member portals, dues and renewal flows, content gating, event registration, and the admin tools staff actually use.
What we build
Services for membership organizations and communities.
Platform work scoped to the real needs of associations, professional communities, and subscription products — not generic web development.
Dues and renewal flows
Online payment, auto-renewal, grace periods, dunning emails, and failed-payment recovery built into the platform. Renewal friction is the leading cause of avoidable churn.
Content and benefit gating
Role-based access so members see what their tier allows: courses, downloads, directories, forums, or live events. Non-members see the right preview and a clear path to join.
Event and chapter management
Registration, waitlists, attendance tracking, and per-chapter or per-cohort segmentation. Works for single flagship events or year-round programming across multiple regions.
Member analytics and retention
Dashboards showing engagement, churn risk, renewal rates, and benefit utilization so staff can act before members lapse. Data surfaced where your team already works.
Admin and staff tooling
Back-office tools for membership staff: bulk imports, manual overrides, communication templates, and audit logs. Built for the people who run programs, not just developers.
Featured engagement
A custom membership and scheduling platform for a global focus community.
Cave Day runs structured deep-work sessions for individuals and teams. The platform handles memberships, session scheduling, content delivery, and access control for a global community of subscribers.

Custom membership and scheduling platform for Cave Day.
We built Cave Day's core membership platform from scratch, covering subscription management, session booking, content delivery, and member access tiers. The platform replaced a patchwork of third-party tools that could not talk to each other. Ongoing engineering retainer with direct CEO partnership.

How engagements start
Three ways we typically work with membership organizations.
Most projects fit one of these shapes. Discovery helps us figure out which applies and what scope actually makes sense.
Portal rebuild
Replace an outdated member portal or AMS module with a custom-built experience that matches your brand and workflows. We handle data migration, member communication, and cutover.
New platform launch
Greenfield build for associations or communities launching a paid membership product for the first time. We scope the MVP, build it, and get you to launch without scope creep.
Integration and migration
Connect your membership platform to your CRM, email system, event tool, or payment processor. Or migrate off a legacy system without losing member history or breaking renewal flows.
Membership-sector compliance
Frameworks membership clients require.
Compliance we have experience implementing on membership and association engagements. Specific compliance is scoped per contract based on what your platform handles, your member geography, and your tax-exempt status. See the Trust Center for details.
Member data privacy
Secure member PII handling. Encryption at rest and in transit. Audit trails for sensitive member records, renewal history, and benefit-access logs.
WCAG 2.2 AA + Section 508
Federal grant recipients, 501(c)(3)/(c)(6) associations, and any membership platform whose members include public-sector procurement face accessibility scrutiny. We design for it from day one.
PCI DSS (assisted)
Dues, renewals, and event payments routed through PCI-compliant processors (Stripe, PayPal, Authorize.Net, custom). Tokenization minimizes cardholder data scope on your own infrastructure.
GDPR for international members
Privacy policy alignment for associations and communities with EU or UK members. Consent management, data subject rights, retention rules, and right-to-erasure workflows.
CCPA / CPRA
California consumer privacy laws apply to most associations with California members. Right to know, delete, and opt out honored.
501(c) tax compliance & reporting
Federal and state filings for tax-exempt associations and 501(c)(3)/(c)(6) organizations. Audit-ready membership-record retention. State professional licensing rules where applicable.
