About lumeportdex
Built for households who plan in decades, not headlines
lumeportdex combines automated rebalancing with transparent modelling, so long-term portfolios stay aligned with the goals they were built for.
Our Story
A model-first approach to long-term investing
lumeportdex was founded on a simple observation: most portfolio drift happens quietly, between the moments anyone is paying close attention. Markets move, allocations shift, and by the time it's noticed, a plan has quietly drifted from its original intent.
We set out to build a system that treats rebalancing and portfolio modelling as an ongoing discipline rather than an occasional check-in — giving households and their advisers a clearer, steadier view of where a portfolio actually stands relative to its goals.
- Started with a focus on transparent, rules-based modelling
- Built around automated rebalancing rather than manual review cycles
- Designed for long-horizon goals, not short-term positioning
Our Mission
Keep every portfolio honest against its own plan
We exist to remove the guesswork from long-term allocation — replacing intuition-driven adjustments with a consistent, documented process that households and advisers can actually inspect.
Clarity over complexity
Every model output is traceable to a stated assumption. Nothing runs as a black box.
Discipline over timing
We build for consistent process, not attempts to predict short-term market moves.
Alignment over activity
Rebalancing happens when a portfolio drifts from plan — not on an arbitrary schedule.
What We Value
The principles behind how we build
These values shape the decisions we make about the platform, the models we support, and the way we communicate with the households who rely on us.
- Transparency: Clients can see how and why a portfolio model reaches its recommendations.
- Consistency: The same rules apply in calm markets and volatile ones alike.
- Accessibility: Long-term planning tools shouldn't be reserved for large accounts only.
- Restraint: We would rather do less, reliably, than promise more than a model can support.
Our Team
A small, focused group behind the platform
lumeportdex is run by a team that works across portfolio modelling, software, and client support. We keep the group deliberately lean, favouring direct accountability over layers of hand-offs.
Modelling & Research
Responsible for the assumptions, allocation logic, and rebalancing rules that drive the platform.
Platform & Engineering
Builds and maintains the systems that keep portfolio monitoring accurate and running continuously.
Client Support
Handles day-to-day questions and makes sure households understand what the platform is showing them.
We intentionally keep team descriptions general on this page. Specific roles, credentials, and contact routes are available through direct correspondence.
