**The product.** One API key and one EU-hosted endpoint for more than 700 AI models from more than 50 providers. It works as a drop-in for the OpenAI, Anthropic and Gemini SDKs and for coding agents such as Claude Code, Cursor and OpenCode. A paid tier adds rules for every model call: spend limits, model allowlists, data-retention settings, checks and routing between models, with automatic failover when one provider is down.

**Why it worked.** European companies that want to use frontier models must answer where the data goes and which sub-processors see it. Opper puts every model behind one data processing agreement, hosting in Stockholm and zero data retention by default, and charges a percentage on top of provider prices instead of a markup on tokens.

Evidence grades: A = disclosed by a public company, a filing or a payment processor, or verified by one; B = two or more independent reports agree, or a journalist confirmed it; C = a founder claim that no one else verified; D = reported, not verified: one founder claim or a third-party estimate with no second source; E = no revenue figure found, so the headline is a non-money fact and the other facts carry their own grades; calc = computed on this page from graded facts.

## Summary

Opper is an AI gateway: a service that sits between an application and the model providers, so the application calls one API and the gateway forwards each request to OpenAI, Anthropic, Google, Mistral or another provider. Its paid tier is a control plane, a layer of rules that decides which models may be called, how much may be spent and what is stored. An LLM router inside it picks a model per request and falls back to another provider when one fails.

Göran Sandahl and Johan Gustafsson, part of the team that built the log-monitoring company Unomaly, founded Opper in Stockholm in 2023, according to the company. The launch post of April 2024 offered the platform "in limited availability". In September 2025 Opper bought FinetuneDB, and its two co-founders joined Opper's leadership. UpNext called Opper a pre-seed company in February 2026.

The home page says Opper is "Trusted by 50k+ developers and companies serving 10M+ users". No revenue figure, customer count or funding amount is published, so the evidence is grade E: a live product with public prices and the company's own claims.

## Pricing

Opper prices in November 2026, from the company's pricing page (grade C)

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Gateway |  |  | pay as you go; 3% platform fee; 700+ models |
| Control Plane |  |  | pay as you go; 5.5% platform fee; org budgets, allowlists, rules |
| Enterprise |  |  | custom contract; dedicated rate limits, SLA, own cloud or region |

All plans are pay as you go on provider rates, plus a platform fee as a percentage. Payment is by Stripe credits on Gateway and Control Plane, by invoice on Enterprise. Sign-up needs no card; free models work in the playground and the API, and premium models need a card, with no minimum. Checks are billed at a flat rate per check on top of the fee.

## When did Opper AI launch, and how did it grow? Timeline

From a 2023 founding by two former Unomaly founders to an EU gateway for 700+ models, in about three years. Each entry carries its grade.

- **2012 to 2022** (grade C [3, 4]): The founding team builds Unomaly, anomaly detection for log data, acquired by LogicMonitor in 2020.
- **2023** (grade C [3]): Göran Sandahl and Johan Gustafsson found Opper in Stockholm.
- **April 2024** (grade C [4, 6]): Launch post: "A Better API for Generative AI", in limited availability with early-access signup.
- **September 2025** (grade C [3]): Opper buys FinetuneDB; its two co-founders become Chief Growth Officer and Chief Technology Officer.
- **February 2026** (grade C [5]): Named in the Techarena TOP46; UpNext reports deployments in defense, government and critical infrastructure.
- **November 2026** (grade C [1, 2]): An EU AI gateway for 700+ models with a 3% fee; the home page claims 50k+ developers and companies.

## Why did Opper AI work?

### One agreement for every model

A European company that adds a new model provider normally adds a new sub-processor to its data processing agreement. Opper offers one DPA with one sub-processor for every model, hosting in Stockholm and zero data retention by default. That turns a legal review per model into one review.

### A fee on usage, not a subscription

The customer pays provider rates plus a 3% or 5.5% platform fee. Revenue grows with the customers' model spend, and sign-up needs no card, so a developer can start without a sales call.

### Failover across providers

The same model is often sold by several clouds. The home page says Claude Opus 5.5 is served by 4 providers and that a single route averaged 93.69% uptime on its own, while the combined route showed 100% over 30 days.

## How it was built

These details come from the company's own pages. They are grade C.

- An OpenAI-compatible endpoint (api.opper.ai/v3/compat) that the OpenAI, Anthropic and Gemini SDKs can use by changing the base URL.
- Model routes from the providers' own clouds and from EU inference partners such as Berget, GreenPT and Sference, listed on the home page.
- A decision model that picks the branch of a route, with backup models when a call fails.
- Payments by Stripe credits on the self-serve plans, invoices on Enterprise.
- ISO/IEC 27001:2022 certification and a trust center for enterprise buyers.

## Who tried this before Opper AI, and why did they fail?

Three companies in our database of failed startups sold one API layer over many other services. The values below are from that database and are not independently verified.

The failed startups come from our database of dead startups, retold here in our own words; Its entries are AI-assisted summaries of public sources, so they carry no evidence grade.

### Singly (2011 to 2016; funding US$2.7M; cause: Competition)

- Promise: One API to collect and sync user data from many social networks.
- Why it died: It depended on third-party APIs that changed and limited access, and broader tools such as Zapier and IFTTT took the market.
- Record: 

### Parse.com (2011 to 2017; funding US$85M; cause: Unit Economics)

- Promise: A backend as a service, so app developers did not run servers.
- Why it died: A generous free tier and usage pricing did not cover costs; Facebook bought it and shut it down.
- Record: 

### Solid (2017 to 2025; funding US$81M; cause: Unit Economics)

- Promise: A unified API to connect enterprise systems.
- Why it died: Each integration added complexity; long sales cycles and support costs broke the unit economics.
- Record: 

## What changed

Singly and Solid sold one API over many services whose owners could change the terms. Opper has the same exposure: it resells access to models that OpenAI, Anthropic and Google also sell directly, often with their own EU regions.

The difference is what the customer pays for. Opper's fee rides on model spend that the customer would pay anyway, and its selling point is a legal one, EU hosting and one processing agreement, which the providers themselves do not offer across each other's models.

## Can one person copy Opper AI now?

**Verdict: Not by one person today.**

A gateway that serves enterprises in defense and government needs ISO certification, uptime across many providers and a sales team, and Opper started with an experienced founding team and venture backers. The smaller idea that a solo founder can copy is a narrow gateway for one rule set or one niche, such as a single regulated industry.

1. Pick a compliance need that the model providers do not solve across each other, such as data residency in one region.
2. Expose an OpenAI-compatible endpoint, so customers change only a base URL.
3. Charge a percentage on top of provider prices instead of a token markup.

**What is still open.** Gateways for one regulated sector or one region outside the EU, where the same data rules apply.

## What could go wrong for Opper AI?

- **What is not verified.** No revenue figure was found. There is no payment-processor profile, no founder interview with numbers and no filing in the sources read; Swedish company registers that would show the accounts of Opper Technology AB block automated reading. The headline "50k+ developers and companies" is the company's own counter with no stated method; in September 2025 the company wrote "thousands". UpNext's report of deployments in defense, government and Fortune 100 companies is a company statement passed on by a pitch-event writer, with no names. A reader could look for the annual report of Opper Technology AB or a funding announcement.
- **Competition and model providers.** On this site, LLM Gateway and ImageRouter sell similar gateways, and Morph, also on this site, is one of Opper's routing partners. Opper resells models from OpenAI, Anthropic, Google and others; the home page lists routes through those providers and their clouds, so price or term changes by them pass straight to Opper's customers.
- **Refusal-removed models.** A models page offers "abliterated" models, versions with refusals removed, "for red teaming, penetration testing and cybersecurity work". The page says "Each model needs approved access" and that some routes run with abuse monitoring.
- **Team size.** Opper was started by two co-founders and added two FinetuneDB co-founders in 2025, but no source gives the total headcount. A company with an ISO 27001 certification and enterprise contracts may well have more people than the four named.
