About
Gaus, Inc. dba Astor provides subscription-based robo‑advisory portfolio management to individual investors, including both typical retail and high‑net‑worth individuals. Services are delivered through a mobile application and text‑messaging channels (including iMessage and WhatsApp) and include personalized, AI‑assisted, non‑discretionary investment recommendations plus an optional trading feature that transmits client‑approved orders to supported brokers.
The firm’s investment process relies on AI‑assisted and automated analysis combined with fundamental and quantitative inputs, using client‑provided information (age, risk tolerance, current holdings, objectives) and connected‑account data to generate tailored recommendations; GAU’s personnel supervise the algorithms but do not exercise investment discretion or take custody. Clients are responsible for implementing recommendations unless they enable the trading feature, which presents proposed U.S. equity transactions for client approval and then forwards the approved orders to the client’s chosen broker.
Noteworthy distinctions include a subscription pricing model (Astor Free, Pro, and Max) rather than percentage‑of‑AUM billing, delivery of advice through messaging channels with some clients served exclusively via those channels, and a trading feature that transmits only client‑approved U.S. equity orders to supported brokers while the firm receives no broker compensation. The firm is newly formed (May 2025), reported $0 in discretionary and non‑discretionary assets as of January 2026, and operates client referral and third‑party affiliate programs that provide economic incentives to promoters.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
