Why teams choose Firma over Opensense

  • Built for tidy signatures, not a sales stack. Opensense is a go-to-market platform that wires signatures into your CRM and ABM tools. If you just want consistent, on-brand signatures across your team, Firma does that without the overhead of a revenue-operations deployment.
  • Self-serve, no demo required. Sign up, design a signature, deploy to Google Workspace in one click or to Microsoft 365 via the Outlook add-in. Most teams are live in minutes, with no sales call or quote.
  • Transparent pricing that fits smaller teams. Public per-seat pricing from $1.20/user/month billed annually ($1.50 monthly), with a real free plan for up to 2 users. Opensense is priced and sold for larger go-to-market organizations.
  • Simple by design. Fewer moving parts means your signatures are live and consistent faster, without integrating a marketing platform first.

If you are a large go-to-market team that needs signatures wired into Salesforce, Marketo, or HubSpot for pipeline attribution, Opensense is built for exactly that. Firma is for teams that want clean, consistent, centrally managed signatures across Google Workspace and Microsoft 365, without an enterprise sales process.
