About Gravenos and Drusus
What is Gravenos?
Gravenos is a London-based technology company. Its first product is Drusus, an AI-powered financial analytics platform. The corporate structure is analogous to the relationship between a research laboratory and its principal instrument: Gravenos holds the intellectual property and operational responsibilities; Drusus is the product through which that work reaches the market.
What is Drusus?
Drusus is an AI-powered financial analytics platform positioned between the institutional terminals (such as Bloomberg) and the consumer brokerage applications. It is built for sophisticated retail investors, independent wealth managers, financial advisors, and small to mid-sized investment funds. The product covers HKEX, NYSE, NASDAQ, LSE, and the major European venues with proper cross-listing reconciliation.
Why two brand names?
The architecture mirrors a pattern common to mature technology companies, in which the parent brand can pursue work across multiple domains whilst each product carries its own identity. Drusus is the first instrument under Gravenos; further instruments may follow in adjacent domains where the same precision of analysis is in demand.
The Product
What can I do with Drusus?
You can ask the AI analyst chat substantive questions about markets and instruments, track your portfolio with proper return decomposition, set price alerts and watchlists, run Monte Carlo scenario modelling, compute Value-at-Risk on positions you hold, and receive the Drusus Daily briefing in your inbox twice a session.
Which markets does Drusus cover?
HKEX, NYSE, NASDAQ, and LSE are first-class citizens of the platform from day one. The principal European exchanges (Euronext Paris, Deutsche Borse, SIX Swiss) are covered for major listings. Cross-listing reconciliation surfaces the relationship between dual-listed names, particularly across the HKEX-NYSE pair, with FX adjustment.
Is Drusus a trading platform?
No. Drusus is an analytical platform. Execution of trades occurs through your existing brokerage. The product is designed to complement, not replace, that arrangement.
Does Drusus give investment advice?
No. Drusus produces analytical commentary, scenario models, and risk computations. It does not produce investment advice within the meaning of the FCA regulatory perimeter. Nothing the product outputs should be construed as a recommendation to buy, sell, or hold any security.
Pricing and Subscriptions

Is there a free trial of the paid tiers?

Drusus Daily
What is Drusus Daily?
Drusus Daily is the twice-daily financial briefing published under the Gravenos masthead. Each edition is generated from verified market data, structured to read as a senior analyst's morning or evening note, and dispatched at 9am and 9pm in each subscriber's local time zone.
Is the briefing written by AI?
The prose is generated by a large language model constrained to use only verified data drawn from named sources. Editorial oversight is provided by Gravenos. The verification layer rejects any data line that is incomplete or stale, so the figures in the briefing are accurate in a way that pure-AI summaries typically are not.
Can I subscribe to Drusus Daily without a paid Drusus subscription?
A weekday morning edition is included in the free Drusus Explorer tier. Both editions, every session, in your local time zone, are included in the paid tiers.
Security and Data
How is my data protected?
Data is held on Supabase infrastructure in the eu-north-1 region, with the controls that a reasonable professional would expect. Passwords are stored as salted hashes. Payment data is processed by Stripe and never transits our servers. Full detail is set out on the Security and Trust page.
Where is Gravenos based?
Gravenos is registered in the United Kingdom and operates from London.
Will you sell my data?
No. Gravenos does not sell data, does not share data with marketing partners, and does not use behavioural advertising. These are architectural commitments, not promotional claims.
