Custom build
Proprietary infrastructure, without starting from zero.
Most requests for a custom platform turn out to be requests for configuration that the requester has not seen expressed before. That is worth establishing early, because building a trading, risk and payout stack from nothing is expensive in ways that only become visible in year two.
Where the difference is real, Nexus builds on its own core rather than from zero: the matching engine, risk authority, account model and operations console already exist, and the custom work concentrates where your model is actually distinct.
The workstreams Nexus maps with you
- 01
Prove the product gap
Establish concretely what your model requires that configuration cannot express. If this step fails, a white-label deployment is the cheaper and faster answer and we will say so.
- 02
Define authority
Decide which system owns each decision — execution, risk, lifecycle, payouts — before any interface is designed. Ambiguity here is what makes custom builds fail late.
- 03
Specify the experience
Trader and operator journeys described concretely enough to be testable, including the failure paths.
- 04
Design integrations
Market data, payments, payouts, identity and any proprietary systems you intend to keep, with contracts defined at the boundary.
- 05
Deliver in controlled slices
Ship working vertical slices that can be validated against real scenarios, rather than integrating everything at the end.
- 06
Operate what ships
Decide before launch who runs it, how it is monitored and how changes reach production. A custom platform nobody can operate is a liability.
Custom does not mean unbounded
A custom engagement still has a defined scope, a defined authority model and defined acceptance criteria. What it does not have is an open-ended promise that any request will be absorbed — that is how these projects consume budgets without shipping.
If part of your requirement is better served by the standard platform, the scoping process should say so. See engagement models for how the commercial structures differ, and see what Nexus costs before committing.
