Fivo is an LLM cost optimization layer for enterprise teams. It sits between your application and any LLM provider (OpenAI, Anthropic, Google, Mistral, and others) and reduces LLM API bills 5–20× measurably across real workloads. Specific optimization techniques are proprietary and disclosed under NDA only.

How does Fivo measure savings?

Fivo's published 5–20× range is measured across 745K real API calls on 24 workload-model combinations (8 workload types × 3 model tiers), with quality scored vs ground truth on every call. Floor cases are published — single-shot RAG on cost-efficient models sees ~1–2× saving. Full methodology is available under NDA.

Fivo was built by a small founder-led team that spent meaningful time on production LLM infrastructure and watched enterprise teams overpay for inference. We publish what we measured and disclose specific mechanisms only under NDA or BAA.

Is Fivo enterprise-ready?

Fivo is HIPAA-eligible with BAA available for healthcare workloads, GDPR-compliant, and SOC 2 Type II is in progress. Enterprise tier offers 99.95% uptime SLA, on-prem deployment, SSO, and a dedicated account manager. Cancel in 30 seconds by reverting your base URL.

What is Fivo's pricing model?

Fivo charges a percentage of measured savings — no flat fees. Growth (25%) for $10K–50K/month spend, Scale (20%) for $50K–500K/month, Enterprise (~15%) for $500K+/month. Community BYOK is free for qualifying teams under $10K/month. If measured savings drop below 2× in any month, that month is free.

What workloads does Fivo serve?

Finance analytics, healthcare workflows (under BAA), code review and generation, tier-1 customer support triage, reasoning and math workloads, multi-turn RAG, and summarization all see meaningful savings in the 5–20× range. Single-shot RAG on cost-efficient models and highly variable agent plans see smaller savings — Fivo publishes these floor cases honestly.

Does Fivo offer on-premise deployment?

Yes, on Enterprise tier. Fivo can deploy into customer infrastructure — on-prem, private cloud, or air-gapped environments — so data stays within the customer's perimeter.

How does Fivo position relative to Helicone, Portkey, LangSmith, Langfuse, and Braintrust?

Different focus, complementary categories. Helicone and Langfuse focus on observability. Portkey focuses on reliability-gateway features. LangSmith and Braintrust focus on evaluation and tracing. All are well-regarded in their domains. Fivo focuses on measured LLM cost reduction with pay-for-savings pricing. Many teams run Fivo alongside an observability tool.

About Fivo — Measured 5–20× LLM Cost Reduction

Q: How does Fivo work internally?

Fivo's specific optimization techniques — including any caching, compression, prompt rewriting, or routing logic — are proprietary and not publicly disclosed. Customers see measured 5–20× cost reduction; mechanism details are available under NDA. What is public: change one URL, your existing prompts and model choice stay the same, your bill reduces measurably.

Fivo measures

every LLM dollar

We believe enterprise teams shouldn't pay 5–20× more for inference than they need to.
Fivo is the cost layer that makes that measurable, with pay-for-savings pricing.

Our Mission

Most enterprise LLM bills are 5–20× higher than they need to be. We built Fivo to measure the gap honestly and close it. Our mission: publish the range, not a single number; publish the floor cases, not just the ceilings; charge only on measured savings; keep the mechanism proprietary so customers can't be commoditized away.

Customer stories — coming soon. We publish verified, signed quotes only. Until then: every number on this site is backed by 745K measured API calls.

Our Principles

What drives Fivo

Measured Affordability

Enterprise LLM bills shouldn’t be 5–20× higher than necessary. Fivo measures the gap honestly across 24 workload-model combinations and charges only on actual savings. No flat fees, no inflated marketing numbers — a published range with floor cases.

Enterprise Compliance

HIPAA-eligible with BAA available for healthcare workloads. SOC 2 Type II in progress. GDPR-compliant. On-prem deployment available on Enterprise. Specific data-handling details are shared under NDA, or BAA for healthcare — not published.

Developer-First

Integration takes 5 minutes — change the base URL in your SDK or HTTP client to your Fivo endpoint. No SDK migration, no code changes, no infrastructure rework. Cancel in 30 seconds by reverting.

Transparent Results

Fivo publishes the measured range (5–20×), the methodology (745K API calls, 24 workload-model combinations), and the floor cases. The mechanism stays proprietary. The outcomes don’t.

Customer Stories

Verified by
real engineering teams

We switched our base URL and saw a 12× cost drop on GPT-4o within the first week. No code changes. The pay-for-savings model meant zero risk for us.

Arjun Mehta

CTO, SaaS Platform · Mumbai, India

Our Claude spend was growing 40% month-over-month. Fivo brought it down ~8× without touching our prompts. The dashboard shows exactly what we save per query.

Sarah Chen

VP Engineering, Fintech · San Francisco, USA

We needed HIPAA compliance and measurable savings. Fivo gave us both — on-prem deployment, BAA signed, and a 15× reduction on our support automation pipeline.
