šSubscriber exclusive: How fintechs can win with growth marketing
6 lessons from Shameer Sachdev, founder and MD of Growth Gorilla

Hi there,
How was May for you?
At Wondrous HQ we welcomed three Year 10 work experience students who each developed creative materials for their own fictional brands - their fresh perspectives and enthusiasm brought such great energy to the office.
The entire team also joined Sport 4 Life UK's RISE UP 2025 challenge, committing to walk 2.5km daily to represent the 25,150 young people in the West Midlands currently out of work, education, or training.
It felt great to combine our daily steps with supporting such an important cause.
I canāt wait to see what Juneās highlights will be!

Our May highlights
How Fintechs Can Win With Growth Marketing
For this month's video series, I sat down with Shameer Sachdev, founder and MD of Growth Gorilla, a growth marketing agency specialising in fintech brands.
With deep expertise in paid media and influencer marketing, Shameer offers tactical wisdom for marketing leaders looking to scale effectively.
Watch the full conversation below.
Here's what we covered:
1. "We know a client is serious when they've reached out to us and they obviously know what channels that we work in, and they are clear as to what role that channel is going to play in their overall marketing mix."
The brands that really get results are those that understand their overall marketing ecosystem and know exactly how specific channels fit into their bigger picture, rather than just shopping around hoping someone else will figure it out for them.
2. "If an ad's not converting, the first thing to do is not panic."
When campaigns underperform, Shameer advocates for a methodical approach: "Go back a step and look at an ad that has performed really, really well, and then look at the iteration process of how you kind of got from the ad that was performing to the ad where you are now."
This systematic review helps identify where optimisation went off track.
3. "The companies that are using influencers in the right way are looking beyond just working with what we call finfluencers."
Rather than defaulting to obvious industry influencers, Shameer suggests finding creators who genuinely speak to your target audience.
The key is "allowing the influencer to produce content that's endemic with their audience versus being really prescriptive about how the influencer should communicate their product, because at the end of the day, the influencer knows their audience better than you do."
4. āInfluencer marketing goes from being a nice to have to a must have."
Shameer draws a clear line on when influencer marketing becomes essential:
"If you've nailed down your product-market fit, you've got your distribution channels like your paid media set up... and you're really clear on kind of what your value prop is and what your message is, at that point, I think it then goes from being a nice to have to being a must have."
5. "Your influencers become subject matter experts that are working within the industry."
For B2B marketing, Shameer recommends a sophisticated approach: creating video series, roundtables, or podcasts featuring industry experts. This strategy "immediately creates a line of communication with your target customer" while elevating your brand through association with respected voices in the field.
Shameer's approach to growth marketing emphasises strategic thinking over tactical execution, authentic partnerships over prescribed messaging, and understanding your stage of growth before investing in advanced channels.
RISE UP 2025 Update
During May, I took part in Sport 4 Life UKās RISE UP 2025 challenge, walking 2.5km a day to represent the 25,150 young people in the West Midlands currently out of work, education, or training.

I set out to raise Ā£250 and contribute to Sport 4 Lifeās goal of collectively reaching 25,150km, and Iām so proud to share that I hit this target. I walked a total of 128km over the month, coming in 16th place on the leaderboard!
The final week was especially memorable, with sea views and coastal walks during my May half-term in Pembrokeshire.
