Startup Growth Case Studies: What I Actually Share
Looking for growth marketing consultant case studies? Here's why I don't publish fake numbers, and what proof I actually give founders before they hire me.
Where Are the Case Studies?
Honest answer: I’m not putting a wall of client logos, fake percentages, and stock-photo testimonials on this page. If you came here expecting “MRR went from $15k to $21k in 6 months” with a smiling headshot next to it, I get why; that’s what most consultant sites do. I just won’t do it here, because most of those numbers on most sites are either unverifiable, missing context, or made up.
What I’ll do instead is tell you exactly what proof I give founders, why I keep the specifics off a public page, and how to judge whether a growth operator is actually credible for a post-seed consumer AI app like yours.
Why Don’t I Post Client Names, Logos, and Big Numbers Here?
Three reasons, and none of them are “I don’t have results.”
First, most of my work happens under an NDA. Startup founders don’t want their MRR, churn rate, or CAC sitting on someone else’s website where a competitor or a future investor can screenshot it. If an operator is publishing your exact revenue numbers without asking, that’s a red flag about how they’ll handle your data, not a green flag about their results.
Second, a number without context is close to meaningless. “MRR grew 40%” means something completely different for a company that had a product launch and a press hit in the same quarter versus one that didn’t. US advertising rules around testimonials exist for a reason: a result has to reflect what an ordinary client can expect, and if it’s unusual, that has to be said plainly. Most case study pages skip that part because the caveat kills the punchiness.
Third, and this is the real one: a case study on a webpage tells you almost nothing about whether I’ll be good for your specific situation. A marketplace with 12% monthly churn and a B2C wellness app with a CAC problem need completely different playbooks. Reading that I “grew someone’s MRR by 55%” doesn’t tell you if I understand your funnel.
What Do I Actually Share When We Talk?
On a call, or during a growth audit, I’ll walk you through relevant work with the actual context attached: what stage the company was at, what the starting metrics were, what changed, over what timeframe, and what else was happening at the same time that also affected the outcome (a funding round closing, a competitor shutting down, seasonality, whatever it was). If a result was unusual, I’ll say so. If the market did some of the heavy lifting, I’ll say that too. For example, I scaled ZuAI to 2M users at $0.02 CAC using GTM, TikTok UGC, and Reddit growth marketing. I’ll show you the numbers behind that.
I’d rather have a 20-minute conversation where you can ask follow-up questions than a paragraph you have to take on faith.
What Framework Do I Use for Post-Seed Consumer AI Growth?
The mechanics don’t change much by company, but the sequence matters. Here’s the rough shape of how I approach it, with the caveat that some of these numbers are rules of thumb from working across multiple startups, and some are things you’d measure specifically for your product.
| Stage of the engagement | What we’re doing | Typical timeframe | Type of number |
|---|---|---|---|
| Instrumentation audit | Check if MRR, activation, retention, and CAC are actually tracked correctly | 1-2 weeks | Measured (your own data, often wrong at first) |
| Funnel diagnosis | Find where users drop off between signup and paid, or between trial and retained | 1-2 weeks | Measured |
| Channel prioritization | Pick 2-3 channels to focus on instead of spreading thin across 6 | 1 week | Rule of thumb, adjusted to your CAC payback |
| Testing cycle | Run structured tests on onboarding, pricing, or acquisition creative | 4-8 weeks | Measured, reported weekly |
| Scale or kill decision | Double down on what worked, cut what didn’t | Ongoing | Measured against your own baseline |
One thing I’m consistent about across every engagement: testing creative volume. I test 25+ new creatives every week across paid channels when acquisition is part of the scope, because at post-seed budgets, you can’t afford to guess which angle works. That number doesn’t move depending on the client, it’s the baseline I use to get a real read fast.
Is 10x User Growth in 6 Months Realistic?
If a board asked you for this, I want to push back a little before you spend a dollar on an operator. 10x user growth in 6 months happens, but it’s rare, and it almost always comes with a specific unlock: a viral loop that’s already showing early signs, a paid channel with unusually cheap CPMs that hasn’t been saturated yet, a partnership or platform change (an App Store feature, a payment processor integration) that opened a new distribution surface. It is not something a growth operator manufactures from a standing start with a normal budget.
What’s actually achievable for most post-seed consumer AI companies with $500k to $5M raised and a working product: 2-4x growth in 6 months if the fundamentals (retention, activation, unit economics) are already reasonably healthy, and the team commits budget and headcount to 2-3 channels instead of spreading across everything. If your retention is broken, growth spend just buys you churn faster. I’d rather tell you that on the first call than take the engagement and let the board meeting go badly anyway.
**Want this done for your startup?**I help early-stage consumer AI founders escape the “great product, zero distribution” trap.
How Do You Know If a Growth Operator Is Credible for Your Stage?
This is probably your real hesitation, so let’s deal with it directly. Here’s what I’d actually check, not just for me, for anyone you’re considering.
| What to check | Why it matters |
|---|---|
| Can they explain a specific mechanism, not just a result | “We ran referral loops” is not the same as explaining why the loop worked and what the k-factor was |
| Do they admit when something didn’t work | Anyone who claims a 100% win rate on tests is either exaggerating or hasn’t tested enough. I’ve had 40+ banned Reddit accounts. |
| Do they ask about your retention before talking acquisition | If they jump straight to ad spend without asking about churn, that’s a gap |
| Do they name what stage their experience is actually in | Pre-seed tactics and Series A tactics are different, someone who claims both equally well is generalizing |
| Will they scope a short paid engagement before a long one | An operator confident in their work will let you test it in 4-6 weeks before committing to 6 months |
You can read more about how I think about this on the about page, and the actual scope of engagements is laid out on the services page.
Will Bringing in an Operator Create Friction With Your Team?
Only if the engagement is scoped badly. At 2-15 people, you might not have a growth hire yet, and the last thing you need is someone parachuting in and rewriting your growth stack without talking to whoever owns it now. The way I scope this: I work with your existing team, not around them. If you have a founder running marketing at night, I’m there to sharpen prioritization and bring an outside read on what’s working elsewhere, not to replace their judgment. If you don’t have dedicated growth headcount yet, that’s a different conversation about what I can cover directly versus what needs a hire.
Either way, the first two weeks are diagnostic, not execution. That’s on purpose. I’d rather find out in week one if there’s a mismatch than four weeks into a retainer.
What’s the Next Step?
On your own, right now: pull your last 3 months of MRR, active users, and trial-to-paid (or activation) numbers into one sheet. Most founders asking a board for growth budget haven’t actually laid their own funnel out in one place. Do that first, it’ll make any conversation with an operator, me or anyone else, ten times more useful. You can also look at the playbooks page for the kind of frameworks I use before we ever get on a call.
If you want a second pair of eyes on that funnel and an honest read on whether 2x, 4x, or something else is realistic for your specific numbers, that’s what the audit is for. No case study slide deck, no guaranteed percentage, just your actual data and a plan.
