Siddhartha Singh has sat on every side of the table that decides where a media dollar goes — platform, agency and client — across 20+ years spanning APAC, EMEA and global markets, bringing strategy, media, data, technology and AI teams into integrated commercial solutions for multinational clients.
Platform-side at DoubleVerify. Agency-side at MediaCom and WPP. Client-side at Travelocity. Most operators have stood on one side of this trade — Sid has stood on all three, which is why the growth work holds up under scrutiny from any side of the table.

Revenue pipeline health, joint business planning, client expansion, strategic partnerships and negotiation across complex regional stakeholders.

Global and regional media principles, campaign toolkits, governance, local market activation and operational SOPs for multinational clients.
Leadership forums, C-suite relationship management and senior stakeholder alignment across agencies, client organisations and technology partners.
Founder of Antigen Strategy, with original frameworks around organisational distinctiveness, uncomfortable growth and high-performance psychology.
Selling and scaling anything that doesn't carry default budget gravity — a new platform, an unproven pilot, a category nobody's asked for yet — takes a specific mix of instinct, not generic sales resilience.
Wins share by making the category case — showing why something does what the default option structurally can't. Narrative before numbers.
Sells belief before inventory. Most pitches start by explaining why something matters at all — that takes real conviction, not a script.
None of it converts without someone who can structure the actual commercial vehicle, and close it.
Lived directly across three roles: the client/agency partnership work spanning Coca-Cola, P&G and SK-II at MediaCom; the Global Strategy Director and EMEA Lead mandate for Coca-Cola; and building Blink, MediaCom's innovation and consulting division, from zero precedent.

Delivered media training and upskilling for 60 APAC marketers for Mars Petcare and 30 media leaders for Coca-Cola Europe.

AI, misinformation and brand-safety governance after the industry’s old wardens have collapsed.
A comparative read of holding-company language, simplification narratives, AI claims and institutional amnesia.
Why strategists matter when organisations automate tactics but abandon the judgment needed to prevent stagnation.
A provocation against optimisation theatre: doing things better is not the same as doing better things.
A long-form cultural argument that algorithms have stopped being tools and become the ambient architecture of choice.
A clear hierarchy for business growth, brand growth and media scale, written for marketers who need commercial discipline.
A leadership essay on managing up, down and sideways when technical competence alone turns into organisational chaos.
An autopsy of the agency model under AI: automation without judgment produces sameness, and human premium is the margin that survives.
Available for senior leadership, strategic advisory, pitch stewardship and AI-enabled growth transformation mandates across India, APAC and global teams.
