Launching 7 September 2026

Engine

The platform underneath community infrastructure.

Engine is a single, unified platform for running communities at scale. Open source at its core, enterprise grade throughout, and already running two live deployments: Junction for technical communities and Switchboard for the third sector.

This is not another event platform. This is the layer everything else is built on.

The Architecture

One platform. Two deployments. No forks.

Engine is where everything is built. Junction and Switchboard are Engine configured for two very different markets, running the same code, the same standards and the same data model.

What it isWho runs itCommercial model
EngineThe platform. Open source core, enterprise grade.Us, anyone self hosting, and enterprisesFree, or enterprise licence
JunctionEngine deployed for technical communities and eventsUs, and any technical community that subscribesSaaS subscription
SwitchboardEngine deployed for the third sector, with a service layer on topUsFreemium and funder programmes

One rule governs the whole codebase: a feature goes into Engine only if both deployments need it. If only one needs it, it lives in that deployment. That single constraint is what stops one platform quietly becoming two products sharing a name.

Why We're Building This

The community platform market is broken. We're rebuilding it from the foundation up.

The Power of Communities

Technical communities are among the most powerful forces in the global engineering economy. They drive knowledge transfer, shape careers, accelerate adoption and build the trust networks the industry runs on. Billions of pounds of enterprise value flows through the ecosystems communities create.

Fragmented Infrastructure

Organisers are duct-taping five, six, seven disconnected tools together, paying more each year for less capability, locked into platforms that reprice without warning, with no real ownership of their data and no path to sustainability.

Rising Costs, Declining Value

Our own platform costs rose from $100 to over $7,500 a year on Meetup alone, and we still needed a stack of additional tools just to operate. Bending Spoons' $500 million acquisition of Eventbrite has consolidated legacy infrastructure further under extraction rather than innovation.

Our Response

Switching tools does not fix fragmentation. It relocates it. Building another SaaS product does not fix ownership, it just changes the landlord. Engine is open source at the core, self hostable, exportable and licensed Apache 2.0, because infrastructure this important should not be something you rent on someone else's terms.

Leadership Perspective

"This is not an incremental product release. This is a structural intervention into a broken market. We are building the system communities should have had from the start. Not tools. Infrastructure."

Ethan Sumner

Founder & CEO

Foundation Services

The part nobody markets and everybody needs.

Every deployment inherits these. They are the hard dependencies underneath every capability above them.

Multi-tenancy & Hierarchy

Tenant, organisation, community, chapter, event, session. Regional grouping with delegated administration, cross-tenant isolation, tenant-level feature flags.

Identity & Authentication

Passkeys, magic links, OAuth, SAML 2.0, OIDC, SCIM provisioning, two factor, full session and device control. One person, one identity across every community in a deployment.

Roles & Permissions

Composable scopes rather than fixed roles, inheritance down the hierarchy with explicit override, delegated administration and approval workflows for publishing, confirming and committing spend.

The Vocabulary Layer

Terms, theming, navigation and field configuration per deployment and per tenant. Sponsor becomes funder. Chapter becomes branch. Attendee becomes participant. This is what makes two very different products from one codebase possible.

Audit & Compliance

Immutable append-only audit log on every mutation with before and after diffs. Consent records, GDPR subject access and erasure with cascade rules, retention policies, data residency selection, SIEM streaming.

Notifications, Media, Search & Jobs

Multi-channel notifications with a preference centre. Media with virus scanning, CDN delivery and alt text enforced at upload. Full-text, faceted and geospatial search. A job queue with retries, idempotency and dead letter handling.

Capabilities

Nine integrated capabilities. One unified system.

Click any capability to explore the full feature set.

The Discovery Layer

Four directories. One trusted ecosystem.

Communities do not exist in isolation. The directories make those connections structural rather than accidental. Free to browse, free to list, with a shared claim, verification, moderation and deduplication model behind all four.

Open Source

Apache 2.0. Published governance. Public roadmap.

The core of Engine is free and open source. Self host it, fork it, run it forever without paying us anything. Full data export in JSON and CSV covering every entity, self service, no fee and no support ticket. Contribution guide and public roadmap from day one.

We make money from the enterprise edition and from the deployments, not from holding your data hostage.

Built for Enterprise

Enterprise infrastructure that happens to be excellent at communities.

Engine is not a community tool that enterprises can adapt. It is enterprise infrastructure built from the ground up. The same platform running a 500-person external conference runs a 10,000-engineer internal guild programme.

Multi-chapter management with centralised governance and regional autonomy

Internal guild and community of practice infrastructure

Centre of excellence governance

Champions programme tracking with participation data

Cross-team and cross-region coordination

Managed cloud, self hosted, on premise and air gapped deployment

Full white labelling including mobile app shell

SSO, SAML, OIDC and SCIM

Role-based access with complete audit logging

Data residency, configurable retention and legal hold

Penetration testing programme and SOC 2 pathway

Commitments

What we commit to

Accessibility, both surfaces

WCAG 2.2 AA across the attendee experience and the admin experience. Organisers have access needs too, and no competitor treats it that way.

No take rate

Payments run through your own Stripe connected account. We do not sit in the middle of your revenue.

Your data, always

Full export of every entity, self service, at any time. JSON and CSV. No support ticket. No fee.

Offline where it matters

Check-in, scanner and point of sale work when the venue's wifi does not.

Performance as a gate, not a hope

Core Web Vitals budgets enforced in CI, with performance gates on every microsite.

The Infrastructure Communities Deserve

Technical communities are not side projects.

Charities are not amateurs with websites. They are the knowledge networks, career pathways and support systems that people and industries depend on.

Engine is the infrastructure that treats them that way.
