One platform for
the entire lifecycle.
Other tools specialize in one area: stress testing, audio analysis, or production monitoring. Hamming covers all of it.

Trusted by banks, healthtech, and high-growth voice AI teams.
Built by engineers from Tesla, Meta, and Citizen.
We have shipped AI systems where mistakes have real-world cost: ML behind hundreds of millions in annual revenue at Tesla, real-time public safety infrastructure at Citizen, and production ML reaching hundreds of millions of Messenger users at Meta, where failures at that scale are silent. We hold voice agents to the same standard.
Voice agents sit where speech recognition, LLMs, text-to-speech, telephony, and business-critical integrations meet, and anyone with a phone number can reach them. Securing them takes repeatable adversarial testing, evidence that every fix held, and infrastructure that scales from prototype to millions of production calls.
Banks, health systems, and high-growth voice AI teams use Hamming as the independent check that an agent is safe to put in front of customers, before launch and after every change. Read about our SOC 2 Type II certification and HIPAA-compliant voice agent testing.
Your data
stays yours.
We do not sell customer data, and we do not train on it. It is used to provide the service to you, and for nothing else.
Bugs caught
by Hamming.
Teams catch these in testing before launch, in red teaming before release, and in live calls with monitoring.
Compliance risks
- A medical agent prescribing medication instead of directing callers to a professional
- A financial agent giving inaccurate tax advice, against compliance policy
- A legal agent offering unauthorized interpretations of contract terms
AI misinterpretations
- An assistant inventing promotions that did not exist
- A travel agent confusing airport codes and suggesting the wrong bookings
- A food ordering agent misreading allergy declarations, putting customers at risk
System and usability failures
- A prompt update that made the agent ignore callers mid-conversation
- Call routing that kept redirecting callers until they gave up
- Latency long enough that callers hung up
Language and voice issues
- A drive-thru agent unable to tell voices apart in a group order
- An agent that could not understand accents, shutting out international callers
- A multilingual agent that ignored every language but English
Before and after
Hamming.
What changes when testing, monitoring, and reporting stop being manual.
Test at scale to catch errors early and check every update.
Before Hamming
- Manual testing took significant time and did not scale
- Every prompt or function change meant retesting by hand, which introduced inconsistencies and errors
- Nobody could see where agents struggled in real customer calls
- Analytics were too coarse to show where performance broke down under pressure
- Tests covered a few hand-written scenarios, and continuous monitoring was hard to keep up
With Hamming
- 50K+ concurrent test calls in minutes replace manual testing
- Real customer calls are flagged and turned into future test cases
- Prompts and functions are retested instantly, with scores for every test case
- Scenario-level analytics show exactly where the agent falls short
- Hours of manual calls replaced
In our customers'
words.
“Hamming's responsiveness and support feel like an extension of our engineering team. For us, unit tests are Hamming tests.”

Co-founder, NextDimensionAI“Hamming saved us a lot of headaches. We caught a critical bug. The agent was saying 'I booked your appointment' but didn't actually book it. We killed it before any customer saw it.”

Questions about
Hamming.
Browse every answer on the FAQ pageHamming reaches 95%+ agreement with human evaluators by using higher-quality models and audio-based evaluation.
Our two-step evaluation pipeline first determines relevancy (should this guardrail apply?), then evaluates, which eliminates false failures from irrelevant checks.
Yes. Hamming signs BAAs and supports HIPAA-aligned workflows and PHI/PII redaction options. We support US-only data residency by default, with single-tenant deployment available for stricter 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 LiveKit, Pipecat, ElevenLabs, Retell, Vapi, and custom voice platforms. Simply add your API key to import agents, and we auto-generate test cases and guardrails 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 50K+ concurrent test calls. The concurrency 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 prioritize customer requests aggressively.
We aim to be the most responsive vendor you work with. 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 50K+ concurrent test calls during enterprise load testing.
Yes. While Hamming provides battle-tested LLM-as-judge evaluation that achieves 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 scoring. We have built 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).
