Shared browsing rooms where couples pick furniture online on one screen
TL;DR Tandemroom is a plug-in for online furniture and home-decor brands. One shopper opens a room and sends a link, and a partner, flatmate or parent joins on their own phone. They scroll the same pages in sync, fill one cart and vote on options. Brands pay a monthly fee because a sofa is rarely bought by one person.
A bed, a dining table or a sofa costs tens of thousands of rupees and usually needs a second person to say yes. Online, that yes happens badly.
One person forwards product links on a chat app, the other opens a different variant, someone asks which grey and the cart just sits there until the weekend. One market research firm says more than 20 million Indians bought home decor online in 2024[2], so the joint decision is common. How many furniture carts stall waiting for a second opinion? Nobody publishes that, and it's the first thing you should measure.
The seed imagined a social, immersive mall with avatars. Avatar malls ask shoppers to learn a whole new world and they've struggled to keep users, so I kept the social bit and dropped the 3D. Here the shared experience is simply two people on the same store page at once.
A brand adds a script to its web store. A shopper taps "Shop together" and an invite goes out as a chat link, with no app and no login. Everyone in the room sees the same product, colour and fabric swatch. Scrolling follows whoever is leading, or each person can wander off and pull the others back. Items go into one shared cart where each person votes yes, no or maybe, with short text or voice notes beside each item. If the brand allows it then a store design advisor can join the room to answer questions about sizes or delivery.
Checkout stays on the brand's own payment page. Tandemroom never takes the order or the money.
The brand pays a monthly fee tied to sessions, with a higher tier that adds the advisor console. Shoppers pay nothing. The nearest public price is a shared-cart app for a hosted store platform, which charges USD 36–170 a month (about ₹3,500–16,400) for shared carts and synced browsing[3]. Your buyers are D2C furniture and decor brands and the online arms of bigger furniture retailers.
A September 2024 market research report expects India's online home decor market to grow by USD 4.78 billion between 2024 and 2028[1], with several big online furniture and decor brands all chasing the same shopper. Paid traffic is pricey, so a brand gets more out of converting the visits it already has. And real-time sync on the web is now cheap to build on standard websocket services.
There's no public figure for co-shopping software in India. The adjacent signals are the 20 million online decor buyers in 2024[2] and the growth forecast above[1].
The buyer count that matters is small - a few hundred furniture and decor brands with enough web traffic to care. Count them bottom-up before you trust any top-down number.
That shared-cart app offers synced browsing and shared carts to merchants on its platform, but it showed no reviews when I checked[3], so its traction is unproven. A consumer co-shopping app works from the consumer side, with shared wishlists, voting and chat paid for through affiliate links to large retailers[4].
I found no merchant tool built for Indian furniture brands with chat-app invites and an advisor who can join. That's the gap, and it may be a narrow one.
| Difficulty | Moderate (37/100) |
| Starting capital | ₹35–65 L |
| Time to launch | 4–6 months |
Sync across mixed phones and slow networks is fiddly, and every store theme will break something. The harder part is commercial though. You have to prove to a brand that rooms lift conversion, and that needs a clean A/B test on its own traffic over several weeks.
No sector licence applies to a co-shopping plug-in. You only need the baseline.
Checkout stays on the brand's own gateway, so Tandemroom holds no money and needs no payments licence.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI promise delivery dates, prices or discounts in a room. Those come from the brand's own systems.

I think this is worth a look if you can build front-end sync well and sell to e-commerce heads. If you want a consumer social app then it is not for you. Prove two things first - that 5% or more of shoppers on two brands' product pages open a room, and that room sessions convert at least one and a half times better than solo ones.
Plan for roughly ₹35–65 L, most of it on building reliable sync and selling to the first few brands.
It can be if rooms clearly lift conversion. The test is whether room sessions convert at least one and a half times better than solo ones at two brands.
Yes, couples buy furniture together everywhere, and the software isn't tied to India. Check your own data protection law on invitees who never signed up.

Thinking about building Tandemroom or something close to it? The make-or-break work is a conversion test a furniture brand will actually believe, and that's the sort of thing I help founders set up. If you need a hand, you know where to find me. Talk to Yash →
