The Specialist Agency

Engineering
for Slack.

We are a specialized engineering agency founded by former Slack employees. We provide high-stakes technical support for migrations, security architecture, and custom internal tools.

Led by Ex-Slack Engineers

Custom Slack App Deployment

const app = new SlackOAuthApp({
  env,
  installationStore: new KVInstallationStore(env, env.SLACK_INSTALLATIONS),
  stateStore: new KVStateStore(env.SLACK_OAUTH_STATES),
  oidc: {
    callback: async (args) => {
      const handler = defaultOpenIDConnectCallback;
      return await handler(args);
    },
  },
})
.event("app_mention", async ({ context }) => {
  await context.client.chat.postMessage({
    channel: context.channelId,
    text: `:wave: <@${context.userId}> what's up?`,
  });
});
                        
23 Custom Apps Built
11 Ent. Migrations

Core Agency Expertise

01 /

Strategic Migrations

We handle the technical and cultural complexity of Enterprise Grid migrations, workspace merging, and multi-tenant divestitures with zero data loss.

02 /

Full-Stack Development

Bespoke integration development using the Slack API, Block Kit, and serverless environments. We deliver documented, production-ready codebases.

03 /

Security Architecture

Hardening Enterprise instances. We implement DLP, EKM, and audit log pipelines to ensure your workspace meets global compliance standards.

Enterprise Grid Migrations

Moving a workspace into an Enterprise Org is more than a data transfer—it's a governance shift. We manage the technical requirements that Slack's basic tools don't automate.

Identity & SSO Mapping

  • Pre-migration SAML/IDP de-provisioning checks to prevent "ghost" accounts.
  • Conflict resolution for shared email domains across the Org.

Integrity & Workflows

  • Custom Profile Field restoration (Slack does not migrate these natively).
  • Workflow Builder and App Webhook re-validation post-migration.

Migration Logistics

  • Slack Connect re-establishment (Channels go offline during move).
  • Audit Log exports for compliance retention before data merging.

Agency Insight

Avoid the "Migration Lockout"

Migrations are cumbersome and can lead to organization downtime or lockout.
We provide a Technical Runbook to minimize risk and manage user expectations.

Professional service
meets technical agility.

Large consultancies lack deep platform knowledge. Slack's internal services can be rigid and cost-prohibitive. Rogue Digital sits in the middle: providing senior-level engineering with the speed of a boutique firm.

Guaranteed lower costs than Slack's internal quotes.

Direct access to engineers (no account managers).
