Cresta vs Respond.io (2026)

Cresta

by Cresta Intelligence Inc.

Respond.io

by Respond.io

Pros

• ✓Autonomous AI Agents across voice, chat, and SMS in 30+ languages with shared memory: context is never lost across channels, handoffs, or between human and AI agents, with real-time action-taking via CRM, billing, and scheduling integrations through Model Context Protocol and API-based function calling.
• ✓Deepest telephony integration coverage in the category: native connections to Five9, Amazon Connect, Nice, Genesys, Avaya, LivePerson, Twilio, and Cisco mean Cresta deploys into virtually any existing contact center infrastructure without rip-and-replace.
• ✓One of the most comprehensive compliance stacks in the AI customer support category: SOC 2 Type II, ISO/IEC 27001, ISO/IEC 42001:2023, ISO/IEC 27701, HIPAA, GDPR, CCPA, CPRA, SOC 3 and TISAX, plus certified Level 1 service provider status under PCI DSS, with Cresta among the first companies certified under ISO 42001 for AI governance.

Limitations

• ⚠Custom pricing with no published tiers, no pricing page and no self-serve trial: enterprise buyers must engage sales to get a quote, which lengthens evaluation compared with vendors that publish rates openly.
• ⚠Enterprise implementation timeline of 2 to 8 weeks: deploying across telephony, CRM, and knowledge integrations requires coordination with Cresta's onboarding team, making it unsuitable for teams that need AI agents live in days rather than weeks.
• ⚠No published autonomous resolution rate benchmark from Cresta directly: Snap Finance documented containment improvement from 6% to 33% as a third-party case study, but Cresta publishes no standard resolution rate metric of its own.

Pros

• ✓Publishes a first-party MCP server, listed in its own integrations directory, that external AI clients including Claude Desktop, ChatGPT and Cursor connect into over both HTTP and STDIO transports.
• ✓A published directory of 42 channels and integrations, spanning nine messaging channels plus voice, email, CRM and commerce, backed by official Meta Business Partner and TikTok Marketing Partner status.
• ✓Financially substantial for its category, with a $62.5M Series B in June 2026 led by Camber Partners with Endeavor Catalyst, and TechCrunch reporting $35M ARR growing 169% year over year at a 30% profit margin.

Limitations

• ⚠Security certifications are limited to ISO 27001 and GDPR, with no SOC 2 Type II, HIPAA or FedRAMP published as of July 2026, which may disqualify it for buyers in regulated industries.
• ⚠Monthly Active Contact pricing scales with the number of contacts reached regardless of whether a conversation converts, and no per-resolution pricing option is offered, which makes ROI harder to attribute at high volume.
• ⚠Advanced and Enterprise both route to Talk to Sales rather than a self-serve checkout, and there is no native Jira or Asana connector, re-verified July 2026.
