Checked building packs and 3D tours for overseas teams shortlisting offices
TL;DR Tourfile scans shortlisted office buildings in 3D and pairs each scan with independently checked facts like power backup, usable floor plate, approval documents and commute times. Overseas teams setting up Indian centres use it to cut a shortlist before anyone flies in. The occupier pays per building, so no landlord or broker gets to shape the pack.
Global capability centres took about 39% of India's office leasing in Q4 2025, out of a record 82.6 million sq ft that year[1]. One research firm counts about 110 new centres set up between early 2024 and late 2025[2].
The people who approve the site usually sit at headquarters abroad. They see brochures and broker decks, which come from people who get paid when a deal closes, and then they fly in to check the claims for themselves.
We found no public data on how many visits a shortlist takes, so that's the first thing to test.
For each building on a client's shortlist, Tourfile delivers one pack. It holds a 3D walkthrough of the actual floor on offer plus the lobby, lifts and cafeteria. Next to that sits a fact sheet built from documents and site checks, not brochures - carpet against chargeable area, generator and UPS capacity, occupancy certificate and fire NOC status, internet carriers present, and commute times from the areas where the client plans to hire.
The seed pitched immersive virtual tours. Those already exist, since 3D-capture firms sell worldwide[3] and Indian property-data platforms offer tours with it in India[4]. A tour on its own is a commodity. What overseas buyers lack is facts they can trust, so the scan is just the wrapper and the checked data is the real product. Tourfile takes no commission from landlords, which is the whole point.
The user is the real-estate or workplace lead at the parent company, or a GCC set-up adviser acting for them. They pay a fixed fee per building, and a shortlist usually runs to 5–10 buildings. Tenant-rep brokers are a second buyer, because an independent pack makes their advice stronger. Prices still need testing, so set them against the cost of one international trip for two or three people.
Rents are rising, so site choice matters more. Bengaluru prime office rent reached ₹163 per sq ft a month in Q2 2026, up 10.7% in a year[5]. One property consultancy says 72% of occupiers plan to grow their portfolio by 10% or more within two years[6]. Phone-based 3D capture has also cut scanning costs.
Nobody publishes a figure for spend on virtual tours or due diligence in Indian commercial property. The narrow signal you can actually count is new GCCs, about 110 in two years[2], each shortlisting several buildings.
The neighbour is the wider leasing market, with 82.6 million sq ft leased in 2025[1], much of it by occupiers who could buy the same pack.
An Indian property-data platform is the closest player, with office transaction data across more than 1.4 billion sq ft plus tours and virtual fit-outs[4]. Global 3D-capture firms supply the capture technology[3]. Large property consultancies run site-selection work for GCCs within bigger mandates.
The gap is a low-cost, independent pack that a buyer can order building by building, without signing up a broker.
| Difficulty | Moderate (33/100) |
| Starting capital | ₹50–90 L |
| Time to launch | 3–5 months |
Scanning is the easy part. The hard part is getting landlords to let you check documents and plant rooms when you aren't bringing them a deal, and then building a name for accuracy fast enough that overseas buyers trust someone new.
We found no sector licence for this. Taking no commission keeps it advisory rather than brokerage, but confirm that with a lawyer in each state [Requires validation].
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI-read documents without checking them. The whole value of the pack is that a person checked the facts.

Here's what can go south -
I like this for a founder from tenant-rep broking or building engineering who knows what to check and has GCC contacts. If you're a 3D-capture specialist with no property background then it's a weak fit, honestly.
Prove one thing first - that 5 overseas buyers will pay for packs on buildings they're already considering.
Plan for about ₹50–90 L for 3D capture kit, a small inspection team and sales to overseas buyers.
We found no sector licence, as long as you take no landlord commission. Confirm with a lawyer in each state, and register for GST once you cross the threshold.
Yes, any market with overseas tenants can use it. Check local brokerage rules, since some countries license anyone advising on leases.

Thinking about building Tourfile or something close to it? The make-or-break work is winning landlord access without bringing a deal, and proving your facts are right, and I'm happy to help you work through both. If you need a hand, you know where to find me. Talk to Yash →
