What they do
Z1 Tech operates at the intersection of advertising and technology. They build proprietary platforms that help publishers and advertisers monetize their digital inventory and reach target audiences effectively. The company provides programmatic advertising solutions, including demand-side and supply-side platforms, designed to optimize ad spend and maximize ROI. Their focus is on scalable tech solutions that solve complex problems in the digital media landscape, serving global clients with tools for automated ad buying and data-driven audience engagement.
How they make money
They operate primarily on a commission-based programmatic advertising model. They earn revenue through margins on ad transactions processed via their technology stack, performance-based marketing fees, and platform subscription charges for publishers using their proprietary software to monetize digital space. Their growth is tied to the volume of ad impressions handled and the efficacy of their targeting algorithms.
Why it's interesting for a marketer
Ad sales at an ad-tech firm puts you at the commercial heart of digital marketing. You sell the exact inventory (video, programmatic, CTV-style formats) that brand teams and agencies buy, so you learn media economics, CPM maths and agency dynamics far faster than in a classic brand role.

Pro tips
- Learn the ad-tech vocabulary cold before the Business round: CPM, fill rate, viewability, SSP versus DSP, header bidding, and the difference between selling to publishers (monetisation) and advertisers (media). Fumbling these ends the interview.
- Prepare one rehearsed 90-second pitch of VDO.AI to a specific Indian publisher, such as a regional news site, with a rough revenue estimate. A concrete pitch beats generic enthusiasm in every round.
- Bring proof of sales aptitude: placement-committee outreach, sponsorship selling, or live-project lead generation. Quantify it (calls made, conversions, money raised) and reuse it in the HR and Final rounds.
