Why startups choose Element for secure communication
Startups prioritize speed but increasingly require privacy guarantees and data control. Element combines user-friendly clients with Matrix protocol features that align with startup needs: end-to-end encryption, federated architecture to control federation decisions, and an extensible homeserver model (Synapse, Dendrite, Conduit) permitting resource-scalable choices. Element removes vendor lock-in, enables compliance-friendly hosting, and supports single sign-on (SSO) integrations such as SAML and OpenID Connect for enterprise-grade onboarding. For content creators and freelancers, Element allows private channels and verified devices for client-to-client secure conversations, while entrepreneurs get operational control of data residency and retention.
Step-by-step Element deployment checklist for startups
Startups benefit from a concise, ordered checklist that fits into DevOps workflows. The checklist below is optimized for reproducibility, minimal downtime, and secure defaults.
- Prepare infrastructure: domain, DNS (A, AAAA, SRV optional), and a VPS or cloud tier.
- Choose Matrix homeserver: Synapse for feature completeness; Dendrite or Conduit for smaller footprints.
- Obtain TLS certificates: Let's Encrypt with automated renewal (certbot) or ACME client.
- Deploy reverse proxy: Nginx or Traefik with strict TLS ciphers and HSTS.
- Install homeserver: Docker Compose or Kubernetes manifests with persistent volumes.
- Configure E2EE key backups and cross-signing policy; enforce device verification.
- Set authentication: SSO via OAuth/OIDC or SAML for company domains; enable MFA.
- Configure rate limiting, CORS, CSP, and anti-spam modules.
- Set up monitoring and logging: Prometheus, Grafana, Loki, and alert rules.
- Implement backup and restore plan for DB and media store; test restores quarterly.
- Harden access: firewall, SSH keys, role-based access, and secrets management.
- Plan migration and onboarding: export scripts, pilot users, and documentation.
Infrastructure and DNS details
A production Element deployment requires multiple DNS records: an A/AAAA for the homeserver, appropriate MX for related email workflows, and optional SRV records if needed by some bridging solutions. Reverse proxy should terminate TLS. Use DNS providers that support API-driven updates for automation and TTL control. For small teams, a single VPS with 2 vCPU and 4–8GB RAM often suffices; larger teams require clustering or higher memory for Synapse workers. Always reserve separate disk for media store and database with snapshot support.

Configuring end-to-end encryption and federation in Element
E2EE must be enabled and properly managed to ensure keys are not lost. Matrix uses Olm and Megolm algorithms; cross-signing, device verification, and key backup are essential. Cross-signing allows user devices to cryptographically trust each other, and encrypted key backups protect users from losing keys when a device is replaced. Enforce device verification for high-risk rooms and configure server-side policies to require E2EE for specific room categories. For federation, limit peers initially to a whitelist to reduce attack surface, and enable server-to-server TLS with strict certificate validation. Use Matrix official docs for keys and federation specifics.
Key backup and rotation
Key backup can be configured to be password-protected or stored with an external key management service. For startups, recommended approach: enable passphrase-protected client backups, export a server-level recovery key kept in a secure vault (HashiCorp Vault or cloud KMS), and rotate keys annually or after a suspected compromise. Test recovery using a staging account and ensure multiple staff members can perform restores under a documented playbook.
Running a Matrix homeserver: free Element deployment tips
Homeserver choice affects resource needs. Synapse is feature-rich and widely supported; Dendrite and Conduit focus on performance and lower memory usage. For startups focused on low cost, Conduit on a 2 vCPU/2GB instance may be workable for a handful of users, but feature trade-offs (bridging, integrations) must be considered. Media storage is often the cost driver—configure external object storage (S3-compatible) to offload media and reduce disk IOPS on the primary server. Use caching (Redis) for Synapse to reduce DB load and enable postgres connection pooling.
Compliance, backups, and recovery for Element startups
Backups must cover Postgres, media store, and server configuration. Schedule automated daily database dumps with WAL archiving and weekly full media store snapshots. Store backups encrypted offsite (S3 with server-side encryption and bucket policies). Establish RTO (recovery time objective) and RPO (recovery point objective) targets; startups commonly aim for RTO = 2 hours, RPO = 15 minutes for messaging critical to customer interactions. Test restores quarterly and document step-by-step restore playbooks including user account reconstitution, device re-verification, and rehydration of the media store.
Monitoring and alerting
Monitoring must include service uptime, queue lengths, DB replication lag, and media store latency. Recommended stack: Prometheus for metrics collection, Grafana for dashboards, Loki for logs, and Alertmanager for notification routing. Suggested alerts: service down, high 500 rates, DB replication lag over threshold, disk usage > 70%, and certificate expiry within 14 days. Create runbooks with escalation paths and include contact info for on-call engineers.
Upgrade procedure and zero-message-loss strategy
Upgrades should follow blue-green or canary patterns with a staging environment that mirrors production. Use Synapse workers to enable rolling restarts and ensure media store remains available during upgrades. Backup before upgrade, perform schema migrations on a replica, and test clients for compatibility. If an upgrade fails, roll back with database snapshot and media store backup. Maintain a compatibility matrix for Element client versions used internally.
Migration from Slack/Teams: practical steps
- Export messages from Slack/Teams using native export tools for the workspace or Microsoft Graph for Teams.
- Transform exports into Matrix-compatible event formats using open-source converters (search community converters on GitHub).
- Import to a staging server and validate message fidelity, threading, and attachments.
- Pilot with a small team, collect feedback on UX differences, then onboard progressively with SSO and MFA.
Costs and sizing: examples for 2026
Estimated monthly cost (USD) using common VPS/cloud options and including object storage and monitoring:
- Team of 5: 2 vCPU, 4GB RAM VPS, 40GB SSD + S3 storage = $15–$35/month.
- Team of 20: 4 vCPU, 8–16GB RAM, 100GB SSD, S3 storage, basic monitoring = $60–$200/month.
- Team of 100: multi-node deployment with Synapse workers, 8–16 vCPU per node, 64–128GB RAM across nodes, high-performance storage, autoscaling, CDN for media = $600–$2,500+/month.
Actual costs depend on traffic, media usage, and retention policies. Use object storage lifecycle rules to move media older than 90 days to cold storage and reduce monthly bills.
Security checklist (operational)
- Enforce TLS 1.2+ and modern cipher suites; HSTS and OCSP stapling.
- Harden reverse proxy and disable weak HTTP methods.
- Implement rate limits for registration and login endpoints.
- Require device verification and use cross-signing.
- Store backups encrypted and test restores.
- Monitor and alert for abnormal activity and spamming.
- Use SSO and MFA for company accounts.
