Trusted by banks, healthtech, and high-growth startups where reliability matters.
Built by data scientists and engineers from Tesla and Citizen
Our team scaled ML systems driving hundreds of millions in revenue at Tesla and built real-time public safety infrastructure at Citizen. We understand voice AI evaluation because we've built production ML systems where reliability isn't optional—it's mission-critical.
Security & compliance
Built for regulated environments where trust, privacy, and audit readiness are non-negotiable.
SOC 2 Type II
We maintain SOC 2 Type II controls to support enterprise security requirements for data protection, access controls, and operational resilience.
HIPAA (BAA available)
Hamming supports HIPAA-aligned workflows for testing and monitoring voice agents that handle protected health information (PHI). We can sign a Business Associate Agreement (BAA).
Enterprise-grade voice AI testing infrastructure
Voice agents operate at the intersection of STT, LLMs, TTS, telephony, and business-critical integrations. Testing them requires more than dashboards—it demands repeatable evaluation, complete audit trails, and infrastructure that scales from prototype to millions of production calls.
SOC 2 Type II & HIPAA compliant
Full audit logs, SSO support available, RBAC, BAA for healthcare, and US/EU data residency. Trusted by Fortune 500 companies and high-growth startups in regulated industries.

Real-time Production Call Analytics
Real-time Production Call Analytics
Gain actionable insights into live calls, with real-time alerts and detailed analytics to optimize agent performance.
Before Hamming
Monitoring was passive and labor-intensive, offering minimal insight into live performance issues
Teams lacked real-time visibility into problems like hallucinations, latency, or underperforming responses
It was difficult to identify, prioritize, and respond to the most impactful issues in production environments
Calls and traces were used reactively for debugging, without a structured process for systematic improvement
Without a unified system for post-deployment analysis, response to issues was slow and performance optimization lagged
After Hamming
All production calls are actively monitored and scored using LLM judges, enabling consistent evaluation at scale
Live calls are automatically tracked for hallucinations, latency, and performance degradation, with issues flagged in real time
Get clear visibility into where your AI voice agents need attention, backed by detailed, scenario-specific analytics
Flagged calls and traces can be instantly turned into test cases and added to your golden dataset for continuous learning
Receive real-time alerts and access a robust analytics platform that surfaces system gaps, user patterns, and optimization opportunities
Compliance Monitoring and Reporting
Compliance Reports
Generate detailed reports to meet regulatory standards and build customer trust.
Before Hamming
Teams struggled to generate comprehensive performance reports, limiting transparency and customer confidence
It was difficult to prove adherence to current or emerging AI regulations, putting teams at risk of falling out of compliance
System monitoring lacked accuracy and clarity, with no automated way to validate or explain AI behavior
Without clear accountability or reporting, enterprise clients lacked confidence in the reliability and responsibility of AI systems
Teams were not equipped to respond to audits or keep pace with fast-moving AI compliance standards and best practices

Why Hamming FAQs
Most testing platforms use cheaper LLM models for evaluation to save costs, leading to inconsistent pass/fail reasoning. Hamming achieves 95-96% agreement with human evaluators by using higher-quality models and audio-based evaluation.
Our two-step evaluation pipeline first determines relevancy (should this assertion apply?), then evaluates—eliminating false failures from irrelevant checks.
Yes. Hamming provides BAA agreements, HIPAA-compliant infrastructure, and PHI/PII redaction options. We support US-only data residency by default, with single-tenant deployment for maximum isolation.
Our RBAC system lets you restrict PHI data access to authorized personnel while giving contractors access to testing environments only.
Hamming natively integrates with VAPI, LiveKit, Retell, and custom voice platforms. Simply add your API key to import agents, and we auto-generate test cases and assertions from your prompt.
We pull tool call data, transcripts, and recordings directly from your provider. You can run your first test in under 10 minutes.
Yes. Hamming supports SSO integration with major identity providers. Combined with our RBAC system, you can manage user access per workspace, enforce access reviews, and maintain enterprise security requirements.
Default workspaces support 50 parallel calls, configurable up to 100+. For enterprise customers, we've run 500-1,000 concurrent calls during load testing. The limit is typically determined by your voice platform's concurrency allocation.
This means you can test thousands of scenarios in minutes rather than weeks of manual testing.
Our internal SLA is 24 hours for simple feature requests and about 1 week for complex features. We deploy to production multiple times per day and prioritize customer requests aggressively.
Our mission is to be the most responsive platform in the space—if you need a feature, chances are we can build it quickly.
Enterprise plans include 99.9% uptime SLAs with 24/7 support and dedicated Slack channels. We provide guaranteed response times for critical issues and dedicated support engineers who understand your deployment.
Our infrastructure runs on AWS with multi-region redundancy. We've handled 500+ concurrent test calls without degradation during enterprise load testing.
Yes. While Hamming provides battle-tested LLM-as-judge evaluators that achieve 95%+ human agreement, you can also define custom evaluation logic, bring your own models, or use our webhooks to integrate external scoring systems.
Enterprise customers work with our team to build domain-specific evaluators—we've created custom scorers for healthcare compliance, financial accuracy, and industry-specific terminology.
Data retention is configurable per workspace. By default, test recordings and transcripts are retained for 90 days, but enterprise customers can set custom retention policies from 7 days to unlimited.
We support automatic PII/PHI redaction at ingestion, and you can request complete data deletion at any time. For healthcare deployments, we follow HIPAA retention requirements.
Hamming maintains SOC 2 Type II compliance and supports HIPAA.
For healthcare deployments, we can sign a Business Associate Agreement (BAA).
