Tiankai Feng Personal Branding in Data: How Tiankai Built an Authentic Voice That Resonates Worldwide

Personal Branding in the Age of Data

In the Data world, technical skills alone aren’t enough to stand out. Data professionals must not only solve problems but also communicate Data, their expertise, values, and personality in ways that make them clear and impactful. This is the power of personal branding in data – an intentional effort to show who you are beyond job titles and company logos.

One of the most inspiring examples is Tiankai Feng, a data strategy and governance leader at ThoughtWorks Europe, musician, author and creative force in the global data community. His journey from data practitioner to LinkedIn thought-leader shows how embracing authenticity can turn passion, personality and quirks into professional impact.

The Unexpected Beginning of a Personal Brand

Unlike many professionals who set out to craft a brand strategy, Tiankai stumbled into it. Around 2018, he began posting more actively on LinkedIn. At the end of 2019, he had a bold idea: combine his passion for music with his data expertise.

“I wrote a rap song about digital analytics,” he recalls. “At first, I only shared it internally with colleagues. They encouraged me to post it on LinkedIn and I was surprised at how many people resonated with it.”

That experiment became a turning point. What started as fun evolved into a unique voice that positioned Tiankai as someone who could make data approachable, entertaining and human. Over time, music and creativity became synonymous with his personal brand.

The Power of Being Approachable in a Complex Industry

Data governance and strategy are often perceived as “dry” or overly technical topics. Tiankai realized that his creative approach not only caught attention but also made conversations easier.

“In data governance, you’re sometimes seen as the ’data police’. People don’t always welcome those discussions. But when I came into meetings, people already knew me as approachable and fun from my online presence. It broke the ice before I even started.”

His personal brand became more than his reputation. It became a relationship builder, transforming how colleagues and clients interacted with him.

Reputation vs. Personal Brand: Choosing Your Own Story

Tiankai emphasizes the importance of curating reputation intentionally through personal branding.

“Everyone has a reputation, whether you work on it or not. If you’re quiet, people will see you as quiet and unnoticeable. If you don’t define your story, others will define it for you. That’s why personal branding matters – it’s about choosing how you want to be perceived.”

This intentional approach doesn’t mean being fake; it means being authentic with purpose. For Tiankai, that meant blending data expertise with creativity, humor and humanity.

Challenges on the Road to Visibility

Like many professionals, Tiankai faced imposter syndrome at the start.

“At first, I wondered, ‘Who am I to post publicly about data?’ The first challenge was simply hitting the publish button.”

As his visibility grew, so did criticism. Some dismissed his success as being “just because of music,” while others questioned whether he was “serious enough” for the data industry.

But Tiankai views criticism as part of the journey:

• Constructive feedback can make your communication stronger.
• Some criticism is inevitable when you stand out.

“As long as the positive outweighs the negative, you’re on the right track,” he says.

Authenticity Over AI-Generated Content

In an era where AI tools can churn out posts and comments at scale, Tiankai stresses the importance of having an authentic voice.

“AI can help with productivity, but if you outsource your voice completely, you lose authenticity. People see through generic, copy-pasted content. Personal branding is about being unique, not a copycat.”

Instead of chasing quantity, he encourages focusing on quality, relatability and authenticity  – traits that make human voices stand out in a digital sea of sameness.

Key Lessons from Tiankai’s Journey

1. Start small, but start – don’t overthink content strategy, begin posting what matters to you.
2. Blend personality with professionalism – let your unique side shine through your work.
3. Expect criticism, embrace growth – being different attracts both fans and skeptics.
4. Authenticity wins – copy-paste content fades but originality endures.

Personal brand outlasts job titles – companies change, but your brand stays with you.

Building Your Own Unique Brand

Tiankai’s journey proves that personal branding in data isn’t about self-promotion, it’s about authentic self-expression. By blending his passions for data and music, he created a unique voice that resonates across industries and continents.

As he puts it: “If you don’t tell your story, someone else will tell it for you.”

So whether you’re a data scientist, strategist or analyst, remember: your brand is more than your skills — it’s your story, your values and your authentic self.
