FAQ
What does Tungsten do?
Tungsten learns how your experts handle a task, then does it in your existing systems. Each result comes with the sources used to produce it.
How do we get started?
Choose one task and bring the expert who does it. In a half-day workshop, they walk Tungsten through real cases, decisions, and exceptions. One fund taught its investment model in six hours.
What happens when something is ambiguous?
Tungsten asks your expert. You decide which actions it can take on its own and which need approval.
Can we check its work?
Yes. You can inspect the source records, actions taken, and output for each case.
Does it keep learning after the workshop?
Yes. Expert feedback teaches it new rules. It also learns from experience, self-reflection, and self-play. Changes are tested before the agent uses them on new cases.
What happens to our data?
Your data is not used to train models. We support zero data retention and VPC deployment, and keep your data separate from other customers’ data. See the Trust Center for SOC 2 Type II, HIPAA, and security details.
Do we have to use a particular model?
No. Tungsten can run on frontier or open-weight models. You can switch models without teaching the workflow again.
