Meet your newest team member.
Sienna is Vega’s general agent for private markets investor relations and operations teams. You interact with Sienna, and she orchestrates a team of specialist agents behind the scenes to get the work done. Sienna can both answer your questions and complete your tasks, in Vega or across the other systems your team already uses.
And yes, there’s a real Sienna: she is in the video.

Nothing changes until a person approves it, and what Sienna does is recorded in an audit trail.

Recipes for the real work
Built-in workflows, hyper-specialised for and co-designed with the asset managers who use them.
- Create a new product
- Set up a data room
- Assemble a DDQ response
- Invite an investor
- Review a subscription
- Record a side letter
- Open distributions
- Run a capital call
- Get a report out
- Transfer an investment
- Set up a task workflow
Save your own skills
When your team has a workflow of its own, save it as a skill and run it as /name. The same rules apply: she proposes, you approve.
She learns what you allow
Memory comes in three layers: personal, team and organisation. A memory is shared beyond you only once it is approved. Brain is what Sienna knows about the firm, built from your connected sources, and anything unconfirmed is flagged as unconfirmed rather than passed off as fact.
An illustration of Brain in VegaOS: a map of what Sienna knows about Celestial, in seven areas: people and organisations, fundraising and onboarding, funds and terms (the largest), money in and out, value and performance, questions and to-dos, and documents and reports. New facts arrive as they are learned from connected sources, and a panel lists what has changed since your last visit. One side letter obligation is flagged as unconfirmed until a Brain review confirms it. Memory layer buttons switch between personal, team and organisation memory.

The real Sienna
Sienna is the name of our general agent for investor relations: one agent across all workflows that our users can call, wherever and whenever they need it.
She is inspired by the real Sienna (pictured), the general agent for our office: always around, happy to help, and she really loves private markets.

Questions we are asked
- Does Sienna ever act on her own?
- No. Reads run directly, but every change becomes a proposal that a person approves, edits or rejects. The gate is enforced in code.
- Which systems can Sienna work in?
- VegaOS itself, and the systems you connect: your CRM, email and calendar, documents and data platforms, with a builder for custom connectors.
- What does Sienna remember?
- Personal, team and organisation memory, with shared memories approved before they spread. Brain holds what she knows about the firm, and unconfirmed facts are flagged.
- How do we know what she has done?
- Every proposal states what it will trigger and who will be notified before it runs, and what she does is recorded in an audit trail.
