Client Testimonials

In their words — reflections from founders, CMOs, and agency partners I've worked with.

I have to give a shoutout to John, our Demand Generation Manager, who has been a key factor in boosting our revenue. He knows his stuff when it comes to paid ads, SEO, and optimizing our Hubspot processes. Thanks to his skills, we’ve seen a significant increase in website traffic, conversions, and revenue.

John brings a rare combination of deep HubSpot expertise and exceptional client communication skills to the table. As InMobi's Account Manager, he consistently demonstrated the ability to translate complex technical solutions into clear, actionable strategies. His recognition as top performer for three consecutive months speaks to his impact, but what truly sets him apart is his ability to build lasting client relationships. He's exactly the kind of talent every HubSpot agency needs.

We were experiencing significant drops in user retention due to voluntary churn, and John took a deep dive into our data to identify the root causes. Through his meticulous analysis, he was able to develop customized automations and solutions that effectively reduced churn and successfully won back previously lost users.

As a bootstrapped founder, trusting your entire marketing function to a solo marketer - especially remote - is a leap of faith. But John quickly proved himself, bringing a perfect mix of strategic thinking and hands-on execution. Despite the time zone differences, he integrated seamlessly with our team and became a crucial part of our growth story.

Before working with John, I was spending way too much time on manual tasks, and it felt like I could never catch up. But he came to the rescue and showed me how to optimize my workflows and automate tasks, so I can focus on other aspects of marketing. Now, my marketing campaigns are running like a well-oiled machine, and I can see the results in the detailed reporting that he has provided.

We were having a bit of trouble with low conversions on our website, even though our products were doing well in retail. But thankfully, we got in touch with John who helped us switch from WooCommerce to Shopify, and basically rebuilt our entire website from scratch. Our website ended up being one of the highest converting ones on the whole Shopify e-commerce platform! We’re super happy with the results and owe a big thanks to John for all his hard work.

As a bootstrapped early stage startup, we sought a skilled marketer to take charge of our entire marketing efforts, while requiring minimal additional resources. We were fortunate to have John Selvinraj join our team, and his past experiences with SaaS companies proved invaluable in rapidly iterating and achieving channel market fit. His efficient and decisive approach was crucial to our success as an early stage startup. We highly value John’s contributions and would welcome the opportunity to work with him again in the future.

I had a tough time trusting freelancers due to my bad experiences with them in the past. However, when I decided to try my hand at website development, my friend recommended John to me. From the very first conversation, it was clear that John was different from other freelancers I had worked with. His ideas and proactive updates about the progress of the project were exactly what I needed. Thanks to him, my website turned out even better than I had imagined. I highly recommend him to anyone looking for a reliable and skilled freelancer.
