Stop renting your intelligence.
Harpoon helps you own AI that specializes in your business: tested on your real cases, trained on your expertise, deployed where you decide, and improving as you work.
Task tested: propose a decision on a home insurance claim, using 500 claims your handlers have already settled.

Conclusion: train an open model for this task, and keep the rented model for the most complex claims.
Downloading an open model takes minutes. Making it a tool your company can rely on is a different job. It takes measuring, passing on your expertise and fixing mistakes, again and again. That's what we do with you.
We start by measuring. The rest follows.
- 01
Measure
Your cases and past decisions become a set of tests. They show, with numbers, what AI gets right and wrong on your work.
- 02
Train
With your experts, we turn your know-how into training data for an open model that specializes in your tasks.
- 03
Deploy
The model runs where your rules require: on your own infrastructure or with the host you choose.
- 04
Keep improving
Every production mistake becomes a new test. When a new open model comes out, we run everything again, and you only switch if it does better.
Move step by step, with proof in hand.
The audit
The starting point. On one precise task, we compare rented models and open models on your real cases.
- Your tests, which belong to you
- The comparison: quality, cost, confidentiality
- A clear recommendation, even if that means keep renting
Your model
If the audit justifies it, we train a model on your expertise and deploy it in your environment.
- A specialized model whose files you keep
- Training data built with your experts
- A deployment that fits your rules
Ongoing improvement
A model goes stale quickly. We improve it as your business learns and carry it forward to each new generation.
- Mistakes turned into tests and fixes
- New models evaluated as they come out
- A record of every version and its results
The day you leave, it all stays yours.
- The model
- Its files are yours. Nobody can change it or take it away from you.
- The tests
- They define what "good" means at your company, whichever model you use.
- The training data
- Your teams' expertise, organized and reusable with every new generation.
- The decision
- You choose when to change models, based on measured results.
Industries where data can't move freely.

- Claims handling, file review, customer replies
- Banking and finance
- File analysis, compliance, document review
- Healthcare

- Accounting and audit
- Checks, classification, audit preparation
Should we stop using frontier models?
No. They are often still the best for the hardest problems. The goal is to own what matters for your repeated, sensitive tasks, and keep renting the rest when that's the right call.
Is owning a model always better?
No, and that's exactly what the audit checks. If a rented model is still the best choice for your task, the report will say so.
What do we need to get started?
One precise, repeated task, examples your teams have already handled, and a subject-matter expert who can confirm what a good answer looks like.
What happens when a better model comes out?
Your tests and data carry over. We evaluate the new model on your tests, train it if needed, and you only switch if the results are better.
Start with one task.
Tell us which one. You'll find out what AI can really do on your work, and whether you should rent it or own it.
