Startup Advisory

Make sense of your business. Find your next move

Hi, I'm Serg!

I help founders make sense of customer feedback, identify what is holding back growth, and decide which hypotheses to test next.

Start with a free introductory session to get to know me and discuss the challenge you're facing.

Serg Kharchenko, startup advisor

Does any of this sound familiar?

  • We have too many ideas and directions. What should we focus on?

    The team is busy, but it's hard to tell which activities will actually move the business toward its goals.

  • We're getting customer feedback. How do we know what really matters?

    We have feedback, metrics, and observations, but they don't yet form a clear picture of what customers need.

  • We're doing so much. Why aren't we growing?

    Marketing, user behavior, conversion, and sales tell different stories. It's hard to pinpoint the problem and understand what's holding us back.

  • We have several ideas for growth. Which should we test first?

    There's no shortage of ideas, but it's unclear which experiment will give us the most useful answer and deserves the team's time.

How I work

First, we look at the context: what you're building, what you want to achieve, and which decisions you need to make.

We examine the data, customer feedback, and reasoning behind your current decisions. We separate what you know from assumptions that still need testing.

Then we choose the problem to focus on and define the next step: what to do or test, and how to assess the result.

What you'll leave with:

  1. A clear picture of your current situation.
  2. A priority problem to focus on.
  3. A well-reasoned next step and criteria for assessing the result.

The decisions remain yours. I help you examine the reasoning behind them and notice what can be easy to miss from inside the business.

Free introductory session

Let's look at your business from a different perspective.

Online · 1 hour

I'd like to invite you to a free introductory session where we can get to know each other, discuss your idea or product, and make sense of your current situation together.

Tell me what you're working on and what's been challenging you. I'll ask questions, share my observations, and help you identify what deserves your attention first.

It's an opportunity to experience my approach firsthand and see whether working together further makes sense.

No obligation to continue working together.

What people I've worked with say

  • Serg brings deep business development experience and a sharp, structured perspective. He quickly identifies bottlenecks and highlights blind spots that are easy to miss, turning complex discussions into practical next steps. He is also open, supportive, and genuinely easy to work with.

    Co-founder, AutoPase · Entrepreneur

  • I had the pleasure of working with Serg for about a year on business development. He showed exactly the kind of flexibility that is extremely valuable in early-stage companies and especially in the fast-moving AI industry. He was able to quickly adapt, understand different business contexts, and support a wide range of initiatives.

    Founder & CEO, EvaAI · AI-powered mental health platform

  • I've known Serg personally for many years, and recently I had the opportunity to receive a very valuable consultation from him on business development and positioning. Serg is a very friendly, approachable, and supportive person. I highly recommend Serg as both an excellent Business Development professional and a great person to work with.

    Founder, Asterman Digital Production Studio

  • I reached out to Serg for help with my startup and was pleasantly surprised by the experience. We had a very productive call during which Serg asked insightful questions about various aspects of my app that I hadn't even thought about before. By the end of the call, I felt like I was able to look at my product from a completely new perspective, and its weak points immediately became much clearer. I'd like to highlight Serge's exceptional professionalism and expertise. Highly recommend! 11/10
