Founding Team | Head of Growth & Client Delivery

thirdi | AI-Powered Marketing & Growth | Full-Time | India (Remote/Hybrid)

About thirdi

At thirdi, we're building the future of marketing—where AI, data, creativity, and human intelligence come together to drive meaningful business growth.

We're an AI-first marketing company combining proprietary technology with hands-on growth expertise to help ambitious brands navigate the increasingly complex digital ecosystem.

Incubated at Stanford and part of Google's startup ecosystem, we're a growing team of entrepreneurs, marketers, engineers, and strategists building a new way for businesses to approach marketing.

We work across industries, business models, and geographies, helping brands solve complex growth challenges through a combination of performance marketing, marketing intelligence, creative strategy, and AI-powered execution.

We're now looking for someone who wants to build the next chapter of thirdi with us.

The Opportunity

We're hiring a founding-team leader to own and scale our client delivery and growth function.

This isn't a conventional digital marketing manager position. And it certainly isn't a role where you simply oversee campaigns and coordinate with teams.

We're looking for someone who can think like a business owner, operate like a strategist, and execute like a practitioner.

Someone equally comfortable discussing growth strategies with a founder, diving into a Meta Ads account to diagnose performance, challenging a Google campaign structure, managing multiple client priorities, and building the systems needed to scale delivery.

You'll work directly with the founders, own a portfolio of clients, and help shape how thirdi delivers exceptional outcomes as we grow across India and international markets.

You'll be joining early enough to build the playbook, not just follow one.

What You'll Own

1. Own a portfolio of clients and their growth outcomes

Take end-to-end ownership of multiple client accounts across industries, marketing objectives, and geographies.

Become a trusted growth partner to founders, CMOs, and senior marketing stakeholders.

Translate business objectives into actionable marketing strategies, execution plans, and measurable outcomes.

Lead client conversations, performance reviews, strategic recommendations, and account planning.

Identify opportunities to expand relationships, introduce new capabilities, and grow account revenues.

Balance competing priorities without losing sight of client outcomes or delivery quality.

2. Drive marketing strategy and execution

Bring strong hands-on expertise across Google Ads, Meta Ads, GA4, and the broader digital marketing ecosystem.

Understand the full marketing funnel—from brand discovery and acquisition to conversion, retention, and revenue.

Diagnose campaign performance, identify growth opportunities, and recommend meaningful optimizations.

Work across performance marketing, creative strategy, content, analytics, SEO, and emerging AI-driven marketing capabilities.

Know when to dive deep into execution and when to delegate, guide, or challenge the team.

Connect marketing metrics with real business outcomes rather than simply reporting impressions, clicks, and leads.

3. Lead delivery across multiple workstreams

Orchestrate delivery across performance marketers, creative teams, analysts, and technology specialists.

Manage multiple projects simultaneously, often across clients with very different business models.

Establish clear priorities, accountability, timelines, and quality standards.

Anticipate problems, unblock teams, and manage client expectations proactively.

Build repeatable processes and operating rhythms that allow us to scale without compromising quality.

4. Build and scale the business with the founders

Help develop thirdi's client delivery model, operating processes, and team structure.

Contribute to hiring, mentoring, and building a high-performing marketing team.

Partner with founders on strategic client relationships, pitches, proposals, and business expansion.

Identify opportunities to improve profitability, account retention, and revenue growth.

Help us expand our presence and delivery capabilities across geographies.

Bring an entrepreneurial mindset to solving problems where the answers aren't always obvious.

5. Shape the future of AI-powered marketing

We're not building another traditional marketing agency.

You'll have the opportunity to work closely with our product and technology teams to bring AI into everyday marketing workflows.

Identify recurring challenges in campaign management, reporting, and client delivery that technology can solve.

Leverage AI tools and automation to improve team productivity and marketing outcomes.

Translate real-world client problems into product insights and opportunities.

Help develop a scalable delivery model where technology amplifies human expertise.

Who We're Looking For

We're looking for someone with 5–10+ years of meaningful experience in digital marketing, growth, or integrated marketing leadership, preferably in a fast-paced agency, growth consultancy, or entrepreneurial environment.

More importantly, we're looking for the following qualities.

A strategic thinker who isn't afraid to execute.

You can develop a sophisticated growth strategy but are equally comfortable opening Google Ads or Meta Ads Manager and understanding what's actually happening.

A strong marketing generalist with deep performance expertise.

You understand how different marketing channels work together and can confidently navigate conversations across acquisition, analytics, creative, conversion, and growth.

Someone who thrives on context switching.

One conversation might involve improving ROAS for a retail brand. The next could be building a lead-generation funnel for financial services or defining an acquisition strategy for an international startup.

You enjoy that variety and know how to prioritize.

A natural client leader.

You build trust through competence, clarity, and ownership. You're comfortable challenging assumptions, managing difficult conversations, and engaging senior stakeholders.

A builder, not just an operator.

You don't need a perfect playbook or a large support team to get started. You create structure where it doesn't exist, solve problems independently, and continuously improve how things work.

Someone with an entrepreneurial mindset.

You understand that startups involve ambiguity, changing priorities, and resource constraints. You see these as opportunities to create impact rather than obstacles.

What Would Make You Stand Out

You've successfully managed multiple client accounts or business portfolios simultaneously.

You've led both strategy and execution for brands with different growth objectives.

You've directly managed meaningful advertising budgets across Google and Meta.

You've built or scaled a marketing team, agency function, or client delivery operation.

You've worked with international clients or across multiple markets.

You've demonstrated the ability to grow existing accounts through strong outcomes and relationships.

You're genuinely curious about how AI is transforming marketing and business operations.

You've previously worked in a startup, built your own venture, or played a significant role in scaling a young company.

What This Role Is Not

We want to be transparent about the expectations.

This is not a role for someone who wants to focus exclusively on campaign execution, account coordination, or people management.

It's also not a position where every process is defined, every team is fully staffed, and every decision comes with a clear instruction manual.

At thirdi, you'll need to move comfortably between strategy and execution, long-term planning and immediate problem-solving, leadership and individual contribution.

You'll have significant ownership, but you'll also need to roll up your sleeves.

Why Join thirdi?

Build, don't just execute. You'll have the opportunity to shape a growing business, establish how we operate, and influence our next stage of growth.

Work directly with the founders. You'll be involved in meaningful business decisions, strategic partnerships, client growth, and company building.

Work across diverse businesses and markets. From emerging startups to established brands, across India and international markets, you'll encounter a wide variety of growth challenges.

Be at the intersection of AI and marketing. You'll work with a company building proprietary marketing technology rather than simply adopting off-the-shelf tools.

Grow with the company. We're looking for someone who sees this as a long-term entrepreneurial journey, with the potential to develop into a broader leadership role as thirdi scales.

The Kind of Person Who Will Love This Role

You might be a senior performance marketing professional ready to move beyond managing campaigns.

You might be an agency account director who wants deeper ownership of strategy, delivery, and business outcomes.

You might be a growth consultant who enjoys solving complex client challenges but wants to build something larger.

Or you might be someone who has already helped build a small business or agency and wants to do it again—this time at the intersection of AI and marketing.

What matters most is that you want to own outcomes, build teams, solve problems, and create something meaningful.

Interested in Building With Us?

We care more about what you've built, the problems you've solved, and the ownership you've demonstrated than impressive titles or big-company credentials.

When applying, tell us:

What have you owned? Share an example of a client portfolio, marketing function, or growth initiative you've independently led.

What impact did you create? Tell us about a measurable business outcome you delivered.

Why thirdi? What excites you about joining an early-stage company and helping build an AI-first marketing business?

If you're looking for a conventional 9-to-5 marketing job, this may not be the right fit.

But if you're looking for an opportunity to build, lead, and grow a business alongside its founders, we'd love to meet you.
