Reliability is a practice, not a product.
That every technology team knows exactly how their system behaves under load — and has a concrete plan to improve it.
We close the gap between 'having tools' and 'using them well'. We make monitoring, testing, and observability work continuously and reliably — as a managed capability that improves every month, not as a project that ends and gets forgotten.
To be the external Performance and SRE team that tech companies across the Americas turn to when they need their system to be reliable — without building an internal team of 10 people to achieve it.
In 3 years, every tech company in LATAM and the US that needs performance engineering, observability, or SRE practices should think of Vantx as the first option: faster than hiring, deeper than a tool, and more reliable than doing it alone.
That no team has to cross their fingers before a Black Friday, a launch, or a marketing campaign. That infrastructure decisions are made with data, not hope.
Values
Data, not opinions
Every number in every report comes from real tests and monitoring running 24/7. We don't say 'I think'. We say 'the data shows'. If we don't have the data, we measure before we opine.
Actions, not lists
We don't deliver generic best-practice lists. We deliver the exact SQL, the exact config, the exact change — with the expected improvement estimate. 'CREATE INDEX idx_x ON table(col1, col2)' not 'consider optimizing the database'.
Async by default
We respect our clients' time and our own. Slack for communication, Loom for explanations, PDF for reports. Meetings exist when they truly matter — not as ritual.
No lock-in
Everything we build uses open-source tools: k6, Grafana, OpenTelemetry, Prometheus. If you decide to end the service tomorrow, everything is yours. We don't create dependency — we create capability.
Knowledge transfer
Our goal is for your team to learn. Workshops, pair programming, code reviews, mentoring. A successful Vantx engagement ends when your team no longer needs us — and that is our best success story.
Continuous improvement, not projects
We don't deliver a report that gets filed away. We deliver a cycle: measure → find → prioritize → implement → validate. Every month the baseline rises. Every month the system is more reliable. That's what we sell.
What we believe
- Most teams don't lack tools. They lack someone who operates them correctly.
- A load test run once is not performance engineering. It's a checkbox.
- Alerts that get ignored are worse than no alerts — they create a false sense of security.
- The cost of an incident is always greater than the cost of preventing it.
- A dashboard that doesn't answer the question you have during an incident is decoration, not observability.
- The difference between a tester and a performance engineer is the difference between running a script and understanding the architecture.
- 100% async doesn't mean 0% communication. It means efficient communication, when it matters, without wasting anyone's time.
- The best deliverable is the one that arrives without you asking for it, with the data you need, in the format you can use.
