About
A narrow tool, on purpose
Ravaki does a small number of things and tries to do them without needing to be explained.
A Product of Blowtrumpet Technologies.
Ravaki™ is the advertiser-facing platform built and operated by Blowtrumpet Technologies, a deep-tech company headquartered in South Delhi, New Delhi. Ravaki is one of Blowtrumpet’s platforms, not a separate company: when you contract for a campaign on Ravaki, your counterparty is Blowtrumpet Technologies.
Ravaki™, Blowtrumpet™, Tejaki™ and State of Ads™ are trade marks of Blowtrumpet Technologies, and registration has been applied for.
Why Blowtrumpet built it
Blowtrumpet exists because the advertising industry optimised itself for impressions rather than outcomes, and built a supply chain so layered that nobody — least of all the advertiser paying for it — could see through it.
Ravaki is the advertiser’s side of the answer. It is where a brand or an agency plans a campaign, controls how it runs, sees what it did, and pays one price for it.
How it works, commercially
This is the part most platforms leave vague, so we will be exact.
Blowtrumpet trades as principal. We buy inventory from creators and publishers on our own book, take title to it, and separately sell you a finished impression product on our own book. We are not an agent and not a neutral middle layer taking a slice of a transaction between you and someone else. We price each side of our business independently — what we pay a creator never sets what you pay, and what you pay never sets what a creator is offered.
What that means for you in practice:
You are charged one all-in price for delivered, verified media.
Your campaign is fully funded before it runs. No credit, no post-payment.
Your funded balance is an advance against invoices under your supply agreement, not stored value — it is applied to campaigns, and is not withdrawable on demand.
An invoice is raised at commitment, not at completion, and everything is quoted exclusive of GST.
We are the merchant of record on every sale. You have one counterparty for the money and one for the delivery, and they are the same company.
We carry the delivery risk. If verified delivery does not happen, that is our exposure, not a line item you absorb.
What Ravaki is built on
AI-native from the foundation. The intelligence that plans, allocates and optimises is Blowtrumpet’s own engine — built in-house, not assembled from licensed parts.
Transparent abstraction. Complexity is managed, not concealed. You should not need to operate the plumbing, and you should still be able to see what it did.
Contextual by design. Ravaki targets context and counterparty — the content, the channel, whose audience — rather than tracking individuals across the internet.
Responsibility, and what we will not do
We do not profile viewers. Blowtrumpet processes no viewer personal data: no tag, no pixel, no cookie, no device identifier, no viewer-side ad call. Targeting is contextual by counterparty — whose audience, never which individuals. This is a property of how the system is built, not a setting you have to trust us to leave switched on.
We do not inflate what we report. Delivery is verified before it is billed and before a creator is paid.
We do not sell attention that was taken by force. Formats are built to be entered voluntarily, and we research their effect on attention and wellbeing openly through State of Ads.
Brand safety is a default, not a premium tier. Contextual controls and verification apply to every campaign.
