How to Break Into Growth Marketing: Sida's Path from Consulting to $100M Budgets
A Career Playbook Case Study
The Role
Sida Lu is the Director of Growth Marketing at Headway, where he manages close to $100 million in annual marketing spend. Previously, he led growth teams at Uber Eats and Lime.
So what is growth marketing? It's not the Mad Men-style advertising you might picture.
"The traditional view of marketing is probably the Don Drapers of the world—you're doing a cigarette ad, you're putting it on TV, you want to seem cool. But over time, particularly around the 2010s, there was much more of a push to be scrappy and hacky, but also put data behind all the actions you were taking."
Growth marketing emerged when companies could finally track what their marketing dollars actually did. "If you look at some of the most famous growth marketers out there, they really cut their teeth when Facebook was blowing up. This idea of funnels and conversion and things that you can track now—that's really what the work I do has evolved from."
At Headway, Sida focuses on attracting mental health practitioners to the platform. At Uber Eats, he ran incentive strategy—those $5 off coupons and free delivery offers you see are exactly the kind of experiments his team would design and test.
The Path
Education: College (major not specified)
Career progression:
- Strategy Consulting — First job out of college
- Uber Eats — Built growth marketing from scratch
- Lime — Continued growth work
- Headway — Director of Growth Marketing (current)
Sida didn't know growth marketing existed when he graduated: "When we graduated, nobody had ever talked to us at school at any point in time about growth marketing. The main thing I knew about was consulting, banking, and maybe accounting."
The pivot came from asking himself the right questions: "If I wasn't afraid of working hard, how do I find a product that I feel good about working hard for? Something that I'm proud of? And if I'm so lucky to find a product like that, how do I contribute in a way that allows many people to feel the same way?"
Those questions led him to growth—the discipline of helping more people discover products you believe in.
Compensation
Growth marketing at top tech companies pays exceptionally well:
| Level | Title | Years | Base Salary | Total Comp |
|---|---|---|---|---|
| Entry | Growth Marketing Associate | 0-2 | $65K-$110K | $70K-$130K |
| Mid | Growth Marketing Manager | 3-5 | $100K-$160K | $120K-$200K |
| Senior | Senior Growth Manager | 5-8 | $140K-$210K | $170K-$280K |
| Director | Director of Growth | 8+ | $180K-$300K | $250K-$500K |
Note: At top-tier companies like Uber, total comp at senior levels can exceed these ranges significantly.
Sida's advice on compensation: "If your goal is to maximize compensation growth, switching jobs and making good choices there is probably the best option."
What Makes This Career Rewarding
1. Immediate impact
"At 23 years old, I was running a team at Uber Eats and I was sending out millions of dollars of promotions—some of which you guys maybe ever saw. That was so cool for me coming out of consulting, in which you're constantly just telling somebody what you think maybe they should do."
2. Sharing products you believe in
"If you are working and are so lucky to work for a company whose product you believe in and admire, there's probably few things better you can do for that company than to share that product to as many people as possible."
What Growth Marketers Actually Do
At Uber Eats, Sida's work included:
- Incentive strategy and testing: "Does it make more sense to offer them $10 or free delivery? Does it make sense to say, 'If you spend $50, we'll give you a bigger discount,' or are they a smaller shopper? Let's offer them a dollar or two here or there and build up behavior."
- Lifecycle marketing: Constant communication with users at different stages
- Paid channels: Managing spend on platforms like Facebook, Google, etc.
The core mandate: "Your job is to find as many people as possible for this product, have more people try it, make sure people are building behavior changes that are beneficial to the company overall."
Why This Role Exists
"For the longest time, especially as more money poured into marketing and more people started to take an interest in sustainable growth, the natural questions that emerged were: how do I know what I'm getting from my investments? Here at Headway, every year I'm probably spending close to $100 million. That's a sizable amount of money. At the executive level, you almost need to be able to point to the effects—like what did I get for this $100 million?"
That pressure for accountability is why growth marketing became data-driven: "Naturally, the things you want to do become much more quantifiable and structured. You're launching experiments instead of a brand campaign on TV."
The Future: AI and Growth Marketing
Sida sees AI creating another wave of change:
"AI has made things a lot more scrappy and possible. When people can vibe code and create their own little hacky test, what does that do to my discipline? What does that do to the speed at which my team is able to execute? I think it's exciting—maybe a decade ahead."
