Institutional financial technology
Trading, portfolio and risk software for institutions.
Wellbridge builds institutional software for trading, portfolio management and risk management — across equities, bonds, foreign exchange, derivatives and crypto. It is designed for banks, hedge funds, asset managers and wealth managers rather than for retail trading. Exposures, risk and margin requirements arrive reconciled, with their assumptions attached and open to review.

The problem
Trading, risk and reporting rarely share one picture.
Execution in one system, positions in another, risk and margin in a third. Each may be right on its own. Together they arrive without the assumptions, the data vintage or the change history that would let anyone check them.
01
Assumptions drift out of sight
The inputs behind a model change faster than the note recording why they were chosen.
02
Numbers arrive without provenance
A figure travels further than the explanation of where it came from.
03
Review is hard to evidence
Without a versioned record, a reviewer can see the answer but not how it was reached.

What we build
Three connections, one chain from trade to decision.
We think of the work as a bridge: it only carries weight when every span is joined.
Data to its origin
Every position, price and input carries where it came from, its vintage and any adjustments — visible at the point it is used.
Models to their assumptions
Assumptions are stored beside the results they produce, so a change can be traced to what it moved.
Analysis to human judgement
Assistance drafts and explains; people validate, sign off and remain accountable.

Our risk product
WellBridge AI Risk Terminal
The WellBridge AI Risk Terminal is Wellbridge’s risk product: positions, exposures, scenario analysis, margin and sign-off on one surface, with every figure traceable to the model and the data it came from.

How we work
Institutional software is a discipline.
Evidence before claims
We describe what something does only when we can show it.
Lineage you can follow
Any figure should lead back to its sources in a few steps.
Review by design
Consequential steps wait for a person. Nothing irreversible happens silently.
Calm, accessible interfaces
Dense information, presented so the important thing is obvious.
Minimal data
We collect what a task needs and nothing more.
