Start to finish
We work inside your team, from companies with lots of legacy tech to teams just getting started with AI.
Here’s to AI that works.
We agentify companies.
We build custom agents and automations that give your team its hours back.
Why Prost
We run on agents ourselves.
We’re AI-first: our own operations run on agents. We build the same kind of system for your company, then keep it working in production.
An agentic company is one where AI agents do the routine work, governed in one place and kept working in production. What is an agentic company?
Production-ready
Evals, guardrails, integrations, cost control and monitoring. We build on proven models from Anthropic, OpenAI and others, and pick the right one for each job.
Nearshore value
We’re based in Buenos Aires, working in your hours, fluent in English and Spanish.
What we build
AI agents
We build agents that work 24/7: they reply fast to prospects, build sales proposals, send invoices, handle complaints and after-sales support, and take on any other business process.
Chat, voice and video
Customer-facing assistants for sales and support. Start with text, then add voice and video as you grow.
Custom AI projects
AI built around your problem, not a template. Internal tools, knowledge assistants and integrations designed and shipped for your stack.
Control plane & AIOps
We govern your agents and keep them running.
Part of every project, on the models and cloud you already use.
Control plane
One place to manage every agent.
- Approvals and permissions
- A record of every run
- Versions and rollback
- Cost limits and policies
AIOps
Keeps agents reliable in production.
- Monitoring and alerts
- Tests on your real cases
- Incident response
- Spend tracked per agent
How we work
Four fixed-scope steps. You see a working prototype on your own data before you commit to production.
Scoping
We learn your process, agree on success metrics and propose a clear scope and price.
Proof of concept
A fixed-scope, working prototype on your real data. You see results before committing to production.
Production rollout
Evals, guardrails, integrations and cost controls, with a control plane. We handle the hard parts that make AI reliable.
Ongoing support
AIOps monitoring, improvements and new features. Your AI gets better as your company evolves.
How we engage
Pick the model that fits where your company is with AI today.
Project
Fixed scope, fixed price. A good fit for a POC or a well-defined agent.
Subscription
Ongoing support, monitoring and improvements. Keep your AI sharp as your needs change.
AI advisory
Architecture reviews and hands-on guidance for teams building AI in-house.
- Fractional CAIO: a part-time Chief AI Officer who sets your AI roadmap and oversees delivery.

Who do you work with?
Companies in the US and Latin America. If a process eats hours of your team’s week, like intake, triage, back-office work or support, we can probably automate it.
Is the control plane a product we license?
No. We build it for your environment as part of the project and run it with you.
How do you handle our data?
We agree on data limits up front. We can deploy in your cloud and use model APIs that do not train on your data by default.
Who owns what you build?
Ownership is set in the contract before we start. At handover your team gets full documentation, or we keep operating it.
How long does a project take, and what does it cost?
It depends on scope. Each step in How we work has its own timeline and price, and we agree on both during scoping, before any build starts.
What models do you use?
Whichever fits. Choosing a model means weighing capability, latency, cost, privacy and deployment constraints. We work with Anthropic, OpenAI, leading Chinese models, open-source models and others, and pick the best fit for each system.
What industries do you serve?
We’ve worked across regulated industries like finance and healthcare, as well as operations-heavy sectors like logistics and professional services. If you have manual processes and data, we can help.
Where are you based?
Buenos Aires, Argentina. We work with clients across the US and Latin America, in overlapping hours, in English and Spanish.
Who actually works on my project?
We’re AI engineers who work inside your team. We’ve shipped production systems in legacy-heavy companies and in teams just starting with AI, so we know when to ship and when to iterate.
