What INTURN Does

Every brand ends a season with product it didn't sell. INTURN built the software to move that inventory - profitably, privately, and with data instead of guesswork.

INTURN is an enterprise SaaS platform for managing and selling excess and end-of-season inventory. Instead of the spreadsheets, phone calls and email threads that long governed the off-price trade, brands load their overstock into INTURN, price and package it, and offer it to buyers inside private, permission-based online showrooms.

The company calls these "controlled offerings." A seller decides exactly who sees which product, at what price, and under what transaction rules. Buyers get a transparent, real-time view of what's available with the detail they need to make a fast decision. The result is a two-sided marketplace that behaves less like a fire sale and more like a negotiated exchange.

Underneath sits the part that matters most to a CFO: analytics. INTURN centralizes inventory data, automates offers and counter-offers, and helps sellers evaluate stock so they recover as much margin as possible rather than dumping it at whatever a liquidator will pay.

The founding insight was simple and slightly uncomfortable. A garment loses value every day it sits in a warehouse, so the winning move is rarely the deepest discount - it's the fastest, best-organized recovery. INTURN turned that idea into a product.

The Problem & Who It Serves

Off-price apparel is a roughly $250 billion global trade. Until recently, it had almost no dedicated technology.

Excess inventory is retail's quiet, recurring headache. Over-ordering, canceled wholesale orders, seasonality and forecasting misses all leave brands holding product that has to go somewhere. For fashion especially, the value of that product falls fast, so the pressure to clear it collides with the risk of undercutting full-price channels or the brand itself.

The old process was manual and error-prone: spreadsheets emailed back and forth, opaque pricing, and liquidators who profited from the seller's lack of visibility. INTURN's answer was to give sellers control and data, and to give buyers a curated, trustworthy view of real inventory.

Its customers are global apparel and fashion brands on the sell side and off-price and discount retailers on the buy side. INTURN has kept most client names private - a feature, not a gap, since confidentiality is part of the pitch - but has described marquee enterprise customers and a network spanning more than 40 countries, with an estimated $500 million of product available on the platform at its peak.

That confidentiality is central. A brand will only sell overstock digitally if it trusts that competitors and full-price customers won't see the discount. Private showrooms were the unlock.

Excess inventory isn't a mistake to hide - it's an asset to recover.INTURN's founding thesis

How It's Different & How It Earns

INTURN's real competition was never just another startup - it was habit. The default alternative was the internal spreadsheet-and-email workflow and the traditional liquidators and jobbers who moved overstock in the dark. Public liquidation marketplaces exist, but they trade transparency for reach in a way many premium brands won't accept.

INTURN's edge is the combination of privacy and data. Controlled offerings keep pricing confidential; analytics make each decision measurable. Being an SAP-endorsed app signaled it could sit inside serious enterprise stacks rather than living as a bolt-on tool.

The business model is classic enterprise SaaS with a marketplace twist: recurring subscription fees for platform access, plus transaction commissions on inventory sold through it. That aligns INTURN with its sellers - it does better when they recover more.

Within the wider market, INTURN occupies the "inventory disposition and recovery" layer that most ERPs and planning tools ignore. It sits downstream of forecasting and upstream of the off-price channel, digitizing the handoff that used to be a black box.

For a fashion brand, the value of the garment declines at a very rapid pace - so speed of recovery is everything.On INTURN's core insight
