Modern vs Legacy

Modern Platform vs AssureSign's Legacy Architecture

AssureSign has been in the market for years with a legacy architecture. Zignature is built for modern cloud-native deployments — REST API, webhooks, MCP server, and embeddable signing that AssureSign doesn't offer.

  • REST API — Full programmatic document lifecycle API.
  • MCP server — AI agent integration via Model Context Protocol — unique to Zignature.
  • Modern UX — Mobile-first, intuitive interface vs AssureSign's dated UI.

Real-World Example

When Your Signing Platform Gets Acquired and Bundled

AssureSign had a solid reputation as an enterprise e-signature platform before being acquired by Apttus (now Conga) in 2018. For customers who were already in the Conga/Apttus ecosystem — particularly Salesforce CPQ users — the acquisition made strategic sense. Conga wanted a native signing capability to complete its revenue operations suite. For customers who adopted AssureSign as a standalone tool, the acquisition created a different dynamic.

A financial services company in the Midwest had been using AssureSign for five years for loan document signing. After the Conga acquisition, their account management relationship shifted. Renewals increasingly came with pressure to expand to other Conga products — contract management, document generation — tools they neither needed nor budgeted for. The standalone renewal option remained technically available, but pricing was no longer transparent, and getting a quote required enterprise sales conversations that dragged on for weeks.

The functional concern was more pressing. As a Conga product, AssureSign's roadmap was now tied to Conga's enterprise CPQ priorities. Feature requests from mid-market customers — better mobile signing experience, native CRM integrations beyond Salesforce, AI field detection — went unaddressed. The platform felt frozen relative to purpose-built alternatives that were shipping meaningful updates every few weeks.

When this company evaluated Zignature, the comparison was stark. Zignature offered AI field detection that AssureSign never built. Native integrations with HubSpot, Pipedrive, and Zoho CRM — not just Salesforce. Remote Online Notarization built into the platform. And self-serve pricing that didn't require a procurement process.

The migration took three days. Their compliance team reviewed Zignature's SOC 2 and ESIGN/UETA documentation, approved the switch, and their templates were migrated with AI assistance. For the first time in years, they had a signing vendor whose roadmap was advancing, not standing still waiting for enterprise CPQ priorities to trickle down.
