Quick answer

What is the best alternative to ChatGPT Enterprise?

Harriet is an alternative to ChatGPT Enterprise for companies that want to roll out AI to every employee without committing to a single model vendor. ChatGPT Enterprise gives your whole team OpenAI's models on an annual contract, with pricing OpenAI does not publish and third-party reports put at $45 to $75 per user per month. Harriet is a control plane with a model router that sits in front of OpenAI, Anthropic, Google, and open-model hosts: IT provisions a desktop AI assistant to every device, decides which models each team can use, sets hard budget caps, and audits every action down to the tool call. Teams still get ChatGPT, and they also get Claude, Gemini, and open models hosted in the EU or US where those are cheaper or better suited. Pricing starts free for up to 3 users and scales from $99 a month. Switching models later is a setting, not a migration.

ChatGPT Business vs ChatGPT Enterprise vs Harriet

Vendor facts checked against OpenAI's published pricing and help pages, August 2026. OpenAI does not publish ChatGPT Enterprise per-seat pricing; the ranges shown are third-party reports.

Fact ChatGPT Business ChatGPT Enterprise Harriet
Platform price $20 to $25 per seat / month; premium seats $100 to $125 Not published, contact sales; reported at $45 to $75 per user / month Free up to 3 users; $99 / month up to 15 users; from $499 / month with 50 users included
Minimum seats 2 Not published; widely reported around 150 None
Contract Monthly or annual Annual only Monthly plans available
Models covered OpenAI only OpenAI only Any model through Harriet's router: ChatGPT, Claude, Gemini, and open models hosted in the EU or US
Spend control Credit budgets, OpenAI usage only Credit budgets, OpenAI usage only Hard budget caps per team and per user, across all vendors
Audit trail Admin console, no compliance logging Compliance API logs Every prompt, model, and dollar logged, plus tool-level MCP audit

At the commonly reported $60 per user, a 20-person team would pay around $1,200 a month for ChatGPT Enterprise. The same team pays $129 a month on Harriet's Startup tier, plus model usage, which stays low when everyday work runs on fast models.

The difference

An enterprise licence manages one vendor. A control plane manages AI.

Neither ChatGPT Enterprise nor Claude Enterprise can set model policies or spending caps for the other vendor's models. Each admin console governs only its own products. Harriet is the layer above them.

01

One policy across vendors

Decide which models each team can use: frontier models for the teams that need them, fast models for everyone else, and open models hosted in the EU or US wherever data residency or cost calls for it. One router, one dashboard, instead of one console per vendor.

02

Spend you can cap, not just watch

Hard budget caps per team and per user, across every provider. A 500-employee education software company saved over $500,000 in year one after replacing fragmented per-team AI subscriptions.

03

Audit down to the tool call

Every prompt, every model, every dollar logged and exportable, with tool-level MCP controls. SOC 2 Type II certified, EU data residency available, and every skill threat-scored before it can run.

Fair is fair

When ChatGPT Enterprise is the right call

No platform is right for everyone. These are the cases where buying direct from OpenAI beats routing through us, and we would rather you know them up front than find out two quarters in.

  • You are deliberately all-in on OpenAI and need their deepest compliance surface: Enterprise Key Management, their Compliance API, or their specific data residency regions.
  • You are large enough that a direct vendor relationship and custom terms with OpenAI matter more than flexibility across providers.
  • Even then, the two are not mutually exclusive: Harriet supports bring-your-own-keys, so some companies run Harriet for the whole workforce and keep a direct OpenAI contract for the teams that need it.

FAQ

Questions buyers ask first.

Is Harriet a replacement for ChatGPT Enterprise?
For most mid-sized companies, yes. Both give every employee an AI assistant with SSO, admin controls, and no training on your data by default. The difference is scope: ChatGPT Enterprise manages OpenAI's models, while Harriet routes to any model you want, ChatGPT, Claude, Gemini, or open models hosted in the EU or US, from one dashboard, with per-team model policies, hard budget caps, and tool-level audit logs across all of them. If your requirement is "give everyone AI, keep control of spend and security", Harriet covers it without an annual single-vendor commitment. If your requirement is specifically OpenAI's own compliance surface, such as their Enterprise Key Management or their data residency regions, that lives only inside ChatGPT Enterprise.
Do employees still get ChatGPT with Harriet?
Yes. Harriet provisions OpenAI models alongside Claude, Gemini, and open models hosted in the EU or US, all through one router. You either bring your own OpenAI API keys, keeping your existing provider relationship and any committed-spend deals, or use Harriet managed credits at provider list price plus a 20% management fee on one invoice. Admins decide which teams get which models, and can mix providers freely.
What does ChatGPT Enterprise cost compared to Harriet?
OpenAI does not publish ChatGPT Enterprise pricing; as of August 2026 it is sold on annual contracts through sales, and third-party reports put it at $45 to $75 per user per month with large seat minimums. Harriet has no seat minimum: it is free for up to 3 users, $99 per month for up to 15 users, and from $499 per month including 50 users, plus model usage through your own keys or managed credits. The models are worth comparing too: ChatGPT Enterprise seats bundle usage of one vendor, while Harriet lets everyday work run on fast, cheap models and reserves frontier models for the teams that need them, which is where most of the savings come from.
Why not just buy ChatGPT Business instead?
ChatGPT Business is the right call for a small group that only wants OpenAI: it starts at 2 seats and $20 to $25 per seat, with premium seats at $100 to $125 for heavier usage. What it does not include is OpenAI's Compliance API logging, Enterprise Key Management, or their enterprise data residency options, and it governs only OpenAI models. Harriet adds the governance layer at a similar price point and applies it across every provider at once, including open models, so IT gets one policy, one audit trail, and one bill instead of one per vendor.
What about choosing between ChatGPT Enterprise and Claude Enterprise?
That comparison usually comes down to which vendor's models and compliance surface you prefer, seat minimums, and how the contract is billed. But it is worth noticing what the choice itself commits you to: either way, one vendor's admin console, one vendor's models, and one renewal negotiation with no leverage. Harriet is the third path: run both vendors' models side by side, compare them on your real workloads, and keep the freedom to shift usage wherever quality or price is better this quarter.
Is Harriet affiliated with OpenAI?
No. Harriet is an independent London-based platform, SOC 2 Type II certified with EU data residency available. ChatGPT access runs through your own OpenAI keys or through managed credits. ChatGPT and ChatGPT Enterprise are OpenAI products; Claude is an Anthropic product; Gemini is a Google product.
