Covers all five challenge themes Culinary TourismAgri & Rural TourismHeritage & Culture TourismEco & Adventure TourismDigital Tourism Innovations

The problem and the opportunity

Tamil Nadu's experiences are world-class. Finding, booking and understanding them is not.

286 million domestic tourists in Tamil Nadu in 2023
1.17 million foreign tourists in Tamil Nadu in 2023

Per the Challenge brief / TN Tourism.

  1. ௧

    Discovery is fragmented

    Cooking classes, estate walks, coracle rides and homestays are found through WhatsApp, word of mouth and hotel desks. There is no one place to search them, see them on a map or plan a trip around them.

  2. ௨

    Local hosts can't be booked

    Home cooks, estate owners, artisans and guides rarely have online booking, check-in or payouts, so they depend on intermediaries or stay invisible.

  3. ௩

    Heritage without stories

    Visitors reach UNESCO temples and centuries-old forts with little interpretation on site: no timeline, no narration in their language, no sense of how the monument rose.

  4. ௪

    Spending misses villages and makers

    Weavers, potters, farmers and village hosts have few direct ways to earn from visitors, and few ways to be found by them.

  5. ௫

    Language is a barrier

    Most travel software is English-first. Many hosts, and many domestic travellers, are more at home in Tamil.

The opportunity: Turn this demand into bookings that reach the people and places that make Tamil Nadu special, in Tamil and English, connected to the state's own systems.

The solution

One Tamil-first platform for the whole journey

Payanam connects travellers with Tamil Nadu's hosts, artisans, heritage sites and official services in one bilingual app and website, from the first idea to the story they share.

  1. 1

    Discover

    Map, curated circuits, festivals, official treks and an AI concierge

  2. 2

    Book

    Live slots, stay date ranges, timed tickets and one checkout for a group

  3. 3

    Experience

    WebAR, Then & Now, audio guides, 360° views and an offline ticket wallet

  4. 4

    Collect

    Heritage Passport stamps and trails, kurals and the pledge badge

    Kolam trip cards, journey invites and the Community feed

The Tamil touch

Tamil at the core, not translated on top

Payanam is made of things every Tamil traveller recognises: the dawn kolam, the Kural, the Tamil month and the sound of Tamil.

A kolam generated by Payanam's kolam engine

Kolam lab: drawn live by the engine

A real kolam engine

Sikku kolams generated from a dot grid by the mirror-curve method: one unbroken line around every dot. A seed draws the same kolam on the server and in the app, down to the last coordinate. 15 presets, from the 3×3 brand mark to Pongal and Karthigai kolams.

Thirukkural, every day

All 1,330 couplets with G. U. Pope's 1886 translation: a kural of the day, and kurals chosen for the moment, like this one on hospitality.

திருக்குறள் Kural 81 Hospitality

இருந்தோம்பி இல்வாழ்வ தெல்லாம் விருந்தோம்பி

வேளாண்மை செய்தற் பொருட்டு.

All household cares and course of daily life have this in view Guests to receive with courtesy, and kindly acts to do.

The Tamil calendar

Solar months computed from the Sun's position, so every date shows its Tamil date and festivals fall on the right day.

Today புரட்டாசி 18 4 Oct

Tamil voice

Ask the concierge aloud in Tamil. Hosts describe a listing by voice and get a pre-filled draft; the price is never guessed.

Bilingual everything

Every screen, listing, heritage story, audio guide and concierge reply in Tamil and English: 3,028 web strings alone, with tests that fail on a missing Tamil key.

The app home screen in Tamil

Selection criterion 1 of 5

Innovation & Relevance

What is new here, and why it matters for Tamil Nadu.

  1. 1

    A real kolam engine

    Authentic sikku, kambi, neli and padi kolams generated identically on the server and in the app. It draws our logo, loaders, share cards and passport covers.

  2. 2

    Then & Now AR

    Monuments rebuild era by era in the browser, beside public-domain historic photographs.

  3. 3

    Tickets that work offline

    Cryptographically signed QR tickets checked at the gate with no signal; the database makes double entry impossible.

  4. 4

    A concierge that can't make things up

    Every listing and price must come from that turn's live tool results, or the reply is retried or replaced by a database-only answer.

  5. 5

    Plan together, pay once

    Journeys and curated circuits matched to real sessions, with votes, roles and one combined checkout.

  6. 6

    A passport that rewards good travel

    Trails for craft workshops, the pledge plus an eco-stay, and official treks, not just check-ins.

  7. 7

    Tamil voice for hosts

    A host describes their experience in Tamil; Payanam drafts the listing and asks for what is missing.

  8. 8

    Built around official systems

    Trek bookings hand off to Trek Tamil Nadu; temple etiquette is sourced from HR&CE, ASI and site pages.

Relevance: All five challenge themes in one product, on Tamil Nadu's terms: Tamil first, official channels respected, value kept local.

Selection criterion 2 of 5

Tourism Impact

Better visits for travellers, new income for hosts and makers, and heritage told with care.

Visitor experience

Discovery, booking, interpretation and entry in one place, in the visitor's language, with offline tickets and audio for low-signal sites.

Cultural value

Heritage stories, Then & Now eras, festivals, kolam and Thirukkural, with the source and licence of every asset recorded.

Local livelihoods

Hosts keep 100% of their listed price; travellers pay a transparent 12% service fee. 11 artisan workshops send bookings straight to the makers.

Sustainability

A carbon estimate on every journey, sustainability scores for stays, site etiquette and a Responsible Traveller pledge, encouraged by passport trails.

Accessible through Tamil

Hosts who don't work in English can list, manage and read their analytics in Tamil, even by voice. Domestic travellers can plan in Tamil end to end.

Works with the state's systems

  • Trek Tamil Nadu: every forest trek links to the official booking. Nothing is sold on Payanam.
  • ASI-style monument entry: Indian, SAARC/BIMSTEC and foreign-national fees, camera fees and session capacity.
  • TTDC-style boat-house tickets: pedal, row and motor boats sold per seat or per boat, scanned offline at the jetty.

Ticket operators in the demo are Payanam demo accounts using publicly posted rate levels, ready to hand over to the real operators in a pilot.

Selection criterion 3 of 5

Selection criterion 4 of 5

Business Model & Scalability

Revenue from the traveller's service fee first, then software that operators and the state will pay for.

Built

Service fee

Travellers pay 12% on top; hosts keep 100% of the listed price. Journeys raise the basket: one checkout, several bookings.

Proposed

Ticketing for operators

Timed tickets, offline gate scanning and sales data for boat houses, monuments and attractions, for a per-ticket fee or a subscription.

Proposed

Content studio for government (B2G)

The studio, audio guides, Then & Now and tourism analytics, licensed to tourism bodies per site or per district.

Proposed

Sponsorships and Host Pro

Heritage-content sponsorship (estimated ₹2–5 lakh per high-traffic site a year) and a Pro tier for hosts at ₹999 a month.

Projection, not results

Unit economics

A steady-state district, 12–18 months after launch, is assumed to reach ₹16.5–44 lakh GMV and ₹2–5.3 lakh platform revenue a month.

Break-even assumption: 3 districts × 60 hosts × 20 bookings a month × ₹2,200 ≈ ₹79 lakh GMV and ₹9.5 lakh revenue a month, against ₹6–8 lakh monthly costs.

Assumptions from docs/BUSINESS_MODEL.md. No users, revenue or partnerships are claimed.

From a corridor to the country

  1. Pilot corridors Madurai–Thanjavur, the Nilgiris, Chennai–Mamallapuram–Kanchipuram
  2. All 38 districts A new district is data, not code
  3. Other states Kerala, Karnataka, Andhra Pradesh, Puducherry, and white-label for tourism boards

Stateless services scale horizontally; a new district is data, not code; a new language is strings and content, not a rebuild.

Selection criterion 5 of 5

Partnerships and pilot ask
