Blowtrumpet Technologies
Advertising worth the attention it asks for
Blowtrumpet is a deep-tech company building AI-native advertising infrastructure — buying inventory from creators and publishers, and selling finished media to advertisers and agencies.
Our platforms are in closed testing. This site is where we write about what we are learning, and where we look for the people who want to build it with us.

Where attention becomes outcome
Advertising stopped being judged on whether anyone remembered it. The industry optimised for impressions instead of impact, interruption instead of experience, and scale instead of meaning. Feeds filled up. Creative became disposable. Attention became something to extract rather than something to earn.
We started Blowtrumpet because we did not accept that as the end state.
We build the plumbing that connects advertisers to creators safely, prices the trade, moves the money correctly, and satisfies tax and financial regulation at every step. Most companies spend eighteen months rebuilding that layer before they get to the work that makes them different. We built it once, properly, and we operate it ourselves.
What makes us different
We trade as principal, on both sides. We buy inventory from creators and publishers in our own name, and we sell a finished media product to advertisers in our own name. We are not a neutral middle layer taking a slice of someone else’s transaction. We take title, we price each side independently, and we carry the delivery and margin risk ourselves. Our margin is disclosed, not discovered.
We collect no viewer personal data. Not minimised. Not anonymised. Not collected. Because the creative is assembled locally before broadcast, there is no ad call — and therefore no tag, pixel, cookie, device identifier or viewer-side request of any kind. Targeting is contextual by counterparty: whose audience, never which individuals. A viewer is never a data subject of Blowtrumpet.
We are built in India, for a world that transacts across borders. Engineered and operated out of Delhi, designed from the first line for the compliance, settlement and tax realities that most advertising software treats as someone else’s problem.
Attention is treated as finite. Interactive and game-based formats that people choose to engage with, built with mental wellbeing as a design input rather than an afterthought.
The products
Ravaki — for advertisers and agencies. The demand side. Plan, launch, control and measure campaigns, with transparent reporting and one all-in price. Built to lift Return on Ad Spend, not impression counts.
Tejaki — for creators and publishers. The supply side. Fair, early and transparent earning from content, starting with the live-streaming economy — the fastest-growing and least well served creator segment there is.
Vedoki — the intelligence engine. The AI-native system that runs underneath both. Internal by design.
