Untangling of a knot into a light bulb

Untangling Tech. Complex Ideas. Plainly Put.

Hi, I'm David. I help B2B tech startups clarify their messaging, sharpen their positioning, and write landing pages that convert. I'm a deeply technical engineer with a knack for making complex products easy to understand and impossible to ignore.

From Complexity to Clarity.

Bridging the gap between your innovative products and the audience that needs them. Technical depth, communicated with clarity.

Deep Technical Understanding

I dive into the core of your offerings, decoding their technical details. With a PhD in applied cryptography and security, I’m used to tackling and understanding complex, cutting-edge technology.

Engaging Copywriting

I take the brain-bending stuff and turn it into clear, compelling messages. Whether it’s revising your website or writing newsletters or sales emails, I’ll help your product connect with the right people.

Blog Entries

Looking to build a community or raise awareness about your technology? I can break down the core concepts, explain the underlying tech, or highlight practical use cases for your product — all while optimizing for SEO.

Marketing Consulting

Together, we can clarify a marketing strategy that puts your product in the spotlight. Step by step, we’ll figure out the best way to communicate and boost engagement while positioning your offering for success.

Growth Consulting

You’ve got happy customers, but user growth is hitting a plateau? Let’s brainstorm together to get that hockey curve going. We’ll use customer feedback and rapid growth-hacking experiments to find what works best.

Knowledge Base

A solid knowledge base makes your technology and services easier to understand — for employees and the outside world. Whether it’s a wiki or technical docs, I’ll help you make it clear, accessible, and well-structured.

I'm a deeply technical engineer at heart who knows how to communicate what matters.

You’ve built something powerful — a system, a product, a platform that solves important problems. You know the tech is solid. But showing others what makes it valuable? That’s not easy.

As engineers, we’re deep in the details. We assume too much. We skip the parts that seem obvious — because to us, they are. But even technical audiences need clarity. They need structure, relevance, and context. Without it, good ideas get ignored.

I help you bridge that gap. With a background in advanced tech and applied research, I understand what you’ve built. But more importantly, I know how to frame it so others do too. Not by oversimplifying — but by finding the core, and making it resonate.
