iRostrum

Run professional online auctions under your own brand

A white-label online auction platform for organisations that need to run professional auctions under their own brand, on their own route to market, with full control over bidder relationships, governance, and growth.

Designed for teams accountable for outcomes, reputation, and long-term growth — whether introducing auctions for the first time or running ongoing auction activity as part of an established business.

Built for organisations that are accountable for how auctions are run

iRostrum is designed for organisations that are accountable for how auctions are run, how bidders experience them, and how the brand is perceived. That includes teams introducing auctions for the first time, modernising an existing operation, or scaling ongoing auction activity within a wider business.

This typically includes teams who are:

If you are responsible for how auctions are run — and how they are perceived — iRostrum is built for you.

Your brand. Your bidders. Your data.

With iRostrum, auctions run under your own brand, on your own website, under your own terms.

You retain control of how your auctions are presented, how bidders engage, how data is owned, and how your auctions operate commercially.

You are not placing lots into a third-party aggregator.
You are building a direct route to market that you control — today and as your needs evolve

How does iRostrum work with your website?

iRostrum is designed to fit naturally within your existing website and digital presence.

Auctions run under your own domain and branding, ensuring a consistent experience for bidders and customers. Visitors remain within your environment throughout the auction journey — from discovery and registration through to bidding and post-auction activity.

From a buyer’s perspective, the experience is fully aligned with your brand and website — not a third-party platform.

The exact approach is shaped around how your organisation operates, and explored in more detail during a demo.

Built around bidder trust and operator accountability

Professional auctions require confident bidders and accountable operators. iRostrum is designed to support both: helping organisations deliver clear, trustworthy auction experiences while retaining the control, governance, and visibility needed to run auctions professionally.

Start with what you need, then scale as you’re ready

Every auction journey is different.

iRostrum supports different operating models — from single seller auctions and one-off events to multi-seller environments — within the same white-label platform.

You can start with a focused approach, refine how you operate over time, and expand your auction activity as your organisation evolves — without changing platform or compromising your brand.

Choose the operating model that fits your business

iRostrum supports different ways of running online auctions. Most organisations start with one of these models and evolve over time as their requirements change.

Single Seller

For organisations selling their own stock or assets, without managing consignments from third-party sellers.

Multi-Seller

For organisations managing consignments and running auctions on behalf of multiple sellers within a single, branded platform.

Marketplace

For organisations operating a peer-to-peer marketplace, where sellers manage their own listings under rules defined and governed by the platform owner.

Supporting auctions across a wide range of sectors

Different sectors bring different operating realities, buyer expectations, and regulatory considerations. iRostrum is used by organisations across a wide range of sectors, each with its own challenges — from asset presentation and bidder behaviour to compliance and reporting requirements.

"After a thorough review of a number of auction platforms, we selected iRostrum, confident they could provide the flexibility, security, performance, and practical auction expertise we needed. Greg’s technical knowledge, combined with Marijke’s experience from working for several major auction houses, gave us a valuable sounding board throughout the project. (...) The iRostrum team became integrated within the wider project team and were both reactive and proactive to the demands of the delivery. Our first auction was a resounding success, and we were delighted to report a 100% sell-through rate; a ‘White Glove’ sale."
