The problem

Students miss campus tech events because listings are scattered, unvetted, and untracked.

Club leads get flooded with unvetted forwards, so they ignore most of them or paste everything into group chats. Organisers can't tell which campuses delivered registrations, so they keep sending posters to random contacts.

The idea

Tack gives each campus one board that only its club lead approves, and tracks which campuses bring in registrations.

1Organisers submit an event and pick the campuses they want to reach.
2Club leads approve or reject it with one tap on WhatsApp.
3Students find approved events on their campus page and calendar, and register.

Price: Organisers pay ₹499 per campus push (a flat fee that includes the club's approval and the campus board slot), or ₹15-30 per verified registration through tracked links. Packs start at ₹9,999 for 30 campuses, including a per-campus attribution report. Clubs and students use it free. Clubs earn event credits or a small payout per verified sign-up (to be validated). These price points are hypotheses to test, not benchmarks.

Who paysHackathon organisers, DevRel and community managers at dev-tool startups, Superteam-style communities, and fest teams who need verified reach into specific campuses. They pay per campus push or per verified registration. Students and clubs use it free.

Who uses itStudents in campus tech clubs and communities (GDG on Campus, Takshila, and similar). The first group is Kolkata chapters such as GDG on Campus JIS University and UEM Kolkata, then chapters across India. The side that does the work is the club lead, who curates one trusted campus board and one-tap forwards it to the club's WhatsApp community.

First 10 users1) Seed supply: Adarsh messages 10-15 Kolkata club leads (JIS, UEM and others, through Takshila and GDG contacts) and offers a free campus board with a calendar feed and a WhatsApp digest. 2) Demand: he posts on X and LinkedIn and DMs hackathon organisers and DevRel people from the builder and Superteam India communities with one offer. He pushes their next event to 10 verified campuses with tracked links, and they pay only if the report shows real registrations. 3) The first 10 buyers come from the organisers he already reaches. The first paid pilot is a single Kolkata or online hackathon pushed through a manual WhatsApp group, with the dashboard built after the first result.

Why not just AIA buyer's own AI agent can write a poster and a message, but it can't supply a network of verified club leads who agree to approve and forward items. It can't give students on one campus a trusted board that only a local lead can post to. It also can't give an organiser independent proof, across many campuses, of which campus produced which registrations. The value comes from the two-sided trust, the aggregated cross-campus data, and the real coordination with real people. A prompt can't replace any of those.

CMU Student Share (Central Hacks winner)
A hackathon-winning app that helps students share information about extracurricular activities on campus. It is a single-campus student-to-student sharing app. Tack has a verified club lead on each campus who curates it, plus a paying outside-organiser side with cross-campus attribution.
Eventsliner
A verified society profile and personalised student feed for colleges in Delhi NCR. Tack targets tech clubs nationally and starts in Kolkata. Its buyer is the external organiser or DevRel team, not the society. Its core is club-lead approval, a one-tap WhatsApp digest, and per-campus registration attribution.
Unstop (college partner listings and promotions)
Free unlimited event listing for colleges, with promotions and registration tooling for organisers. Unstop is a central marketplace with open listings. Tack is a trusted-gatekeeper network: nothing reaches a campus unless that campus's club lead approves it, and organisers see which campuses delivered.
