FAQ
Questions teams ask before they reach out
Straight answers on what Van Data Team builds, who it fits, and how projects start.
What does Van Data Team build?
Van Data Team builds AI agents, reporting workflows, data pipelines, automation systems, and modernization work for teams that need production-ready delivery.
Who is the best fit for Van Data Team?
The strongest fit is a team with a real workflow bottleneck, a delivery owner on the client side, and a need for senior implementation rather than slideware.
Can you work inside an existing stack?
Yes. Many engagements start from an existing stack that needs stabilization, better observability, or a new AI and data layer added on top.
How do projects usually start?
Projects usually start with a scoped conversation, a workflow review, or a short strategy sprint that clarifies the bottleneck, risks, and recommended next step.
Why work with a Vietnam-based delivery partner?
A Vietnam-based delivery model can keep overhead lean while still giving global teams senior ownership, strong communication, and timezone overlap that supports steady delivery.
How is a project priced?
Each engagement gets a fixed price in a written scope after a free 30-minute call: a short Strategy Sprint to scope and de-risk the work, a fixed-quote Production Build, or ongoing Embedded Partner support billed monthly or by the hour. Each service page lists its typical range.
Who owns the code and the data?
You do. Once the invoice is paid in full, everything written for you is yours, and cloud, API and AI model accounts are opened in your name. Your data stays confidential during the project and for three years after it, and a data processing agreement is signed before any personal data is shared.
How do we work together day to day?
In English, in writing and on calls, on Vietnam time (UTC+7), which covers the APAC working day, the morning in the UK and Europe, and the start or end of the day in the US. You work directly with the founder who scopes and builds the system, and progress is visible in your own repository and tools.
What happens after handoff?
Every system ships with documentation and a handoff. If a deliverable does not meet the agreed scope and you report it within 30 days of acceptance, it is fixed free of charge, and monitoring and improvements can continue under an Embedded Partner engagement.
