Why Prosperus
Middle and back office, without the spreadsheets.
Most firms run the book on a core system plus a dozen workbooks that fill the gaps. Prosperus is built so the gaps do not exist.
One book of record
Portfolios, funds, transactions, fees and the general ledger share one data model, so a valuation, a NAV and a trial balance always agree with each other.
Dual control by default
Transactions, subscriptions, redemptions and investment strategies go through a maker-checker workflow. Nothing material happens on one person's say-so.
An audit trail you can hand over
Every change is attributed and timestamped. Reports carry their as-of date and your disclaimer. When the regulator or the auditor asks, you export. You do not reconstruct.

Client portal
A client portal that carries your brand, not ours
Your clients sign in to a portal with your logo, in English or Greek, light or dark, on any device. They see performance, income, costs and positions, download statements through secure expiring links and protect their account with two-factor authentication. It runs on the same platform your staff use, so there is no second system to keep in sync.
Explore the client portalOur approach
Honest by design
We would rather tell you what a number means than make it look impressive.
“The page states its own age.”
Valuations, NAV screens and reports show their as-of date and price source. A stale number is labelled as stale, and the page offers a recalculation instead of pretending to be live.
“Beta and tracking error require a benchmark, which is not yet modelled.”
That sentence is in the product today. When a metric cannot be calculated properly, the platform says so instead of showing a plausible-looking figure.
“Save, revert, post, unpost.”
A NAV is a decision, not a cell in a spreadsheet. Prosperus records who took it, when, and lets you reverse it visibly.
How it is delivered
One platform, your configuration
White-label
Your logo, your report footnote, your disclaimer. Clients see your firm, not ours.
Multi-tenant
Each firm runs in its own tenant with its own roles, teams, settings and data.
Modular licensing
The menu shows only the modules your licence includes. Add more when you need them.
OpenID Connect SSO
Staff sign in through your identity provider. Clients get two-factor authentication.
