Hero connects online shoppers with real store associates, by text or by video, so someone browsing a website can talk to an expert standing on the shop floor. It was used across fashion, footwear and homeware, by luxury names and mass retailers at the same time, and was later acquired by Klarna.
If you only read one part
Close the tab and the conversation was gone. In seven months I designed the WhatsApp channel and Reserve, which let a shopper put an item aside in-store without leaving the chat. One in three who talked online then walked in.
WhatsApp gives a business 24 hours to reply, so every message had to earn its interruption. Designing to that rule is why spend per purchase rose 70%.
The problem
Customers could chat and video call while they were on the site. The problem was everything that happened after they left it.
Conversations died the moment the browser tab closed.
Chatbots were already failing to hold anyone's attention.
Compliance and GDPR governed every message that could be sent.
People do not expect to buy through a messaging app, so the habit itself had to change.
No way for an associate to follow up, and no route to an upsell.
WhatsApp Business limits businesses to a 24-hour reply window.
Messages had to reach the right associate, not a queue.
Returning customers needed a reason to come back at all.
The interesting part was never building a chat. It was working out which messages deserved to interrupt someone, and designing a channel that stayed useful to the business without ever feeling like spam to the customer.
The goal
Three things, agreed before anything was designed.
01.
Give associates a channel they own
Let teams text and email their own customers, so the relationship outlasts a single session.
02.
Recover the sales being lost
Tell customers when something is back in stock, so a no becomes a later yes.
03.
Make it feel like a shop floor
Connect shoppers with named experts in named stores, socially rather than transactionally.
What I did
Ran the research with both sides of the conversation.
Surveys and interviews with shoppers, then store visits to sit with associates. The associate interviews were the ones that changed the design. They knew exactly which conversations converted and which wasted a day, and none of that was in the brief. Alongside it, a UX audit of the existing mobile and web experience and a competitor analysis to see what the category had already tried and failed at.
Designed the WhatsApp customer chat.
The entry point on the retailer's site, the department routing, and the handover to a named associate in a named store. The hard part was continuity: a customer starts on a website and finishes in a third-party app, and the design had to make that feel like one conversation rather than two. That included what the business profile shows, how the first message sets expectations, and what happens when the associate is not available.
Designed Reserve, from availability check to pickup.
A customer could check whether an item was in stock in a nearby store, reserve it inside the conversation, and receive a card confirming it was waiting for them. Behind that sat the product picker, variations for colour and size, store location by geolocation or postcode, a limit on how many items could be held, and a reserved-items list so associates could track, cancel and follow up.
Wrote the one-time notification templates with content design.
Anything sent outside the 24-hour window had to be a pre-approved template. Working with the content design team, we built them around the three things people actually messaged about: checking stock on something out of stock, following up on a purchase, and collecting an item in store. Compliance stopped being a blocker and became the thing that kept the channel worth opening.
Mapped the associate experience alongside the customer one.
Contacts split by whether a customer was added in store or online, chat claiming so a single associate owned a thread, and a CRM sync so profiles carried spend history, order history and preferences. Designing both sides at once was the only way the routing rule could actually hold.

The outcome
customers went into a store after interacting with the clienteling experience.
spend per purchase
One in three is the hardest handover in retail, an online conversation turning into a physical visit, and it is the thing every clienteling product promises. It was the number that made the case internally.
Behaviour changed too. More customers used WhatsApp to chat and shop, in a market where buying through a messaging app was not yet a habit for most people.
And the conversations were worth more. Average order value rose when people could get help on demand, which is what made this a commercial result rather than a nicer experience.
