Vellum vs Sistava

Vellum started in 2023 as a Y Combinator-backed platform for building and evaluating enterprise LLM applications, then relaunched in 2026 as a personal AI assistant under the tagline "Your Personal Intelligence." It runs across web, macOS, iOS, CLI, email, Telegram, and Slack, holds persistent memory, and gets its own identity so it can act on your behalf. The open-source MIT runtime can deploy to Vellum Cloud or your own infrastructure. It is currently in early access via a waitlist, with no paid pricing announced yet.

> **Bottom line:** Vellum is a single personal assistant for one person. Sistava is built to scale from one AI employee to a full team of specialists (sales, marketing, support, ops) under a leader who delegates.

## Profile

- **Pricing:** Early access via waitlist. Free one-click install planned for macOS. No paid tiers announced yet.
- **Founded:** 2023, New York, as a Y Combinator-backed enterprise AI dev platform; relaunched in 2026 as a personal AI assistant under "Vellum: Your Personal Intelligence"
- **Funding:** $25.5M+ raised across seed and Series A ($20M Series A led by Leaders Fund, July 2025)
- **Focus:** Personal AI assistant with persistent memory that browses the web, manages files and calendars, and acts under its own identity (a dedicated email, GitHub account, and Slack handle)

## Why choose Sistava as an alternative to Vellum

- Vellum is a single personal assistant for one person. Sistava is built to scale from one AI employee to a full team of specialists (sales, marketing, support, ops) under a leader who delegates.
- Vellum is in early access with a waitlist and no announced pricing. Sistava is live today with published plans (Free + $25/$50/$100/$200 per month) you can sign up for right now.
- Honest concession: Vellum's identity model, giving the assistant its own email, GitHub account, and Slack handle so it acts as a real participant rather than a tool bolted onto your accounts, is a genuinely interesting design choice we have not shipped.

## What is Sistava?

Sistava is an AI workforce platform where you hire AI employees and work with them through conversation. Tell an employee what you need in plain language, and Sistava handles the setup behind the scenes, including the tools, context, and team coordination needed for the work. You do not need to learn AI configuration or build workflows first. You can start with the work you want done, stay involved in the decisions that matter, and see how your team is moving forward.
