It Was Harder Than Coding: Lessons I Learned About Communication as a Startup Engineer

For years, I talked to computers. You write code, it runs. If it crashes, it tells you where the problem is. Computers don’t misunderstand you, they don’t argue, and they certainly don’t miss deadlines. They are the easiest colleagues in the world.

Then I started my startup. And suddenly, my real work wasn’t just building software—it was talking to people. Investors, users, my team. And they all spoke completely different languages.

This realization hit me harder than any debugging session I’ve ever had. I was technically brilliant, but I failed at what mattered most: getting people to understand the value of what I built. A short book I read recently crystallized my mistakes and offered practical lessons, which I’ve combined here with my personal experiences.

1. Know Your Audience: Who Is the Message For?

I still remember my first investor pitch vividly. For half an hour, I explained every technical detail of the AI model we had developed. Algorithms, efficiencies, data processing pipelines—I proudly waited for recognition of my genius.

Then came the question: “That’s nice, but whose problem does this solve, and how will it make money?”

I was devastated. I had spoken to a person like they were a machine.

The book stresses the importance of knowing your audience. Investors want to know the market size, revenue potential, and return on investment. Users care about the tangible benefits in their lives. Team members don’t just want instructions; they need to know why the work matters.

The lesson cost me an investment round—but I never forgot it: message purpose comes first, technical brilliance second. You have to craft your words for the right person in the right context.

2. How You Say It Matters As Much As What You Say

As an engineer, facts and data were always my priority. But the book reminded me that nonverbal cues can be more powerful than the words themselves.

I recalled team meetings where I would sit with crossed arms, monotone voice, saying:
“Folks, these are the tasks for this week.”

Nothing changed. Motivation stayed flat.

Then, I tried something new. Same message, but I added eye contact, gestures, and enthusiasm. I shared why I was excited about a new feature, how it would energize customers, and why it mattered. That day, creativity soared, ideas multiplied, and engagement skyrocketed.

The insight is simple yet profound: people don’t just want instructions—they want purpose, passion, and context. Showing excitement is contagious.

3. The Power of Being Brief and Specific

This has always been my Achilles’ heel. I want to explain every little detail to prevent questions, misunderstandings, or errors. But in communication with investors, users, or teams, nobody has time for a five-paragraph novella.

The book’s advice: “Be brief and specific.” Initially, it felt shallow. I feared leaving out critical details.

But then I understood: brevity shows respect for the recipient’s time. A clear, concise message answers three essential questions:

1. What’s the problem?
2. What’s the solution?
3. What’s the expectation?

Answer these simply and directly, and your message lands. The more you practice, the more effective your communication becomes.

4. Storytelling: Making Technical Work Relatable

Another key takeaway: humans respond to stories, not specifications. I started framing technical achievements around real-world impact.

Instead of saying:
“Our AI reduces processing time by 40%.”

I began saying:
“Our AI saves our users an hour every day, letting them focus on creativity instead of repetitive tasks.”

Same fact, different impact. People remember benefits, not numbers. Communicate with empathy, and you connect.

5. Adapting Communication Across Roles

Different audiences require different approaches:

• Investors: Focus on opportunity, market, and ROI. Avoid technical jargon unless it supports value.
• Users: Highlight benefits, simplify explanations, demonstrate real impact.
• Team members: Combine purpose with clear instructions. Motivate and guide.

Recognizing this early could have prevented countless misunderstandings in my startup’s early days.

6. Listening Is Part of Speaking

Effective communication isn’t one-way. The book emphasizes active listening.

• Ask questions.
• Observe reactions.
• Adjust based on feedback.

When I started truly listening to investors’ concerns, users’ complaints, and team frustrations, my solutions became sharper, presentations smoother, and relationships stronger.

7. Communication Is a Skill, Not Just a Soft Talent

This lesson hit me hardest: communication is one of the hardest skills a founder can master. It’s not a soft skill; it’s foundational.

A brilliant product without clear, purposeful communication fails. I’ve seen it countless times. Conversely, a solid product communicated effectively wins trust, attention, and funding.

I still stumble. Misjudged presentations, unclear emails, and poorly timed updates happen. But now I can diagnose the problem quickly, and that’s half the solution.

Conclusion: The Engineer’s Paradox

Coding and debugging are predictable. People are not. Yet understanding them is what makes or breaks a startup.

Here’s what I’ve internalized:

1. Audience first: Tailor messages for the right person.
2. Emotion matters: Passion and context enhance understanding.
3. Brevity is respect: Clear and concise beats detailed and confusing.
4. Story over specs: Impact resonates, numbers alone do not.
5. Listen actively: Communication is a dialogue, not a monologue.

A product can be exceptional, but if it can’t speak, your vision falters. As an engineer turned founder, I’ve learned that communication is as critical as code—perhaps even more so.
