Product Engine
Model every product, rate, and fee as configuration, not code.
The Product Engine is where your lending catalogue lives. Rates, fees, LTV bands, term ranges, incentives, and eligibility criteria are all first-class configuration, versioned and testable. Product managers can shape and ship new propositions in hours, with engineering only involved when a genuinely new capability is needed.
What it does.
Versioned product catalogue
Every product, rate card, and fee schedule is versioned, diffable, and rollback-safe. See exactly what was live on any given day.
Rich pricing model
Tiered rates, LTV and loan-size bands, incentives, cashback, product fees, and cross-subsidies modelled as data, not bespoke code.
Eligibility and matching
Attach eligibility criteria to products so the same rules govern search, DIP, and full application.
Effective dating
Schedule products, rates, and fees to go live at a specific date and time, with clean cut-over across every channel.
Test in the open
Champion and challenger new products against real cases in a sandbox before you promote them to live traffic.
One source of truth
The same catalogue powers calculators, broker portals, direct journeys, and downstream servicing.
