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

• ✓Runs a hosted, first-party MCP server that Claude and ChatGPT connect to with OAuth from their connector directories, and AI Agents can be managed directly from Claude or ChatGPT.
• ✓Broad channel coverage in one inbox, from WhatsApp, Instagram, TikTok, Messenger, Telegram, LINE, WeChat and Viber to SMS, VoIP calls and email, backed by official Meta and TikTok partnerships.
• ✓AI Agents that qualify leads, book appointments, update the CRM and answer voice calls in more than 30 languages, with AI usage included on Growth and above and a privacy policy that rules out training on customer content.

Limitations

• –The trust center lists ISO 27001 and GDPR only, so buyers who need a SOC 2 report or HIPAA coverage should confirm them with the vendor before procurement.
• –Monthly Active Contact pricing scales with the number of contacts reached rather than with resolved conversations, and WhatsApp fees from Meta are billed on top, which makes costs harder to forecast at high volume.
• –AI Agents are not part of the Starter plan, and the Advanced and Enterprise plans are bought through sales rather than a self-serve checkout, with Enterprise pricing not published.
