Dahlke Tech

A tiny consulting and software company based in Cologne, Germany.


All consulting services are provided by me, Felix Dahlke, personally. Drop me a line if interested - I offer a free consultation.


Since I took my first job as a programmer in 2005, I've been building software professionally. In 2012, I took on my first real leadership position, which culminated in me becoming CTO and managing director in 2015. After growing the company from seven to more than 230 employees and 55 MM EUR annual revenue, I joined another startup as CTO in 2020, which I ran and grew for two years. Unfortunately, we were unable to secure funding in the economic situation of 2022 and had to shut down. In January 2023, I started my own business - this one.

Given my experience in CTO roles, technical leadership is probably my main selling point. Remote organisations and teams, full or hybrid, are where I'm most experienced, having run such places since 2012, long before the COVID-19 pandemic.

Technologically, I've always been a generalist, happy to work with pretty much any code base or tech stack, legacy or modern, from web and mobile to systems programming and infrastructure. Even in leadership positions, I always work directly with development teams to kick off new products, get problems under control, and to generally ensure good practices and quality in the technical organisation. On my own time, I especially like to dabble with Lisp, game development and robotics.

When asked if I focus on leadership or technology, my answer is usually that I refuse to chose just one. I like both, and good leadership can come from deeply understanding both the work and the workers.


Given my background and passion, I can support you best at the intersection of technology and leadership - or people and machines.

As CTO, I've built and launched new products, scaled up existing products to hundreds of millions of users, developed successful company strategies, created teams and scaled them up into entire business units or separate businesses, managed acquisitions, hired hundreds of software developers, product professionals and managers, trained entry-level developers, coached dozens of people in leadership roles, managed reorganisations, change processes and layoffs.

I´d be happy to help you with any of these things.


Interim tech lead (e.g. CTO)

For a few months, I take on a leadership role in your organisation, immediately filling the vacuum as well as finding and training a replacement.

Right hand person

For a few months, I act as the right hand person for someone holding a leadership role in your organisation: I'll stabilise the situation by taking work off their desk immediately, and work with them to ensure they can fill their role well and spend their energy where it has the most impact going forward.

Individual coaching

I'll support one or more people in your organisation with regular coaching sessions; helping them perform well in their current role, or grow into a new one.

Technology and organisation assessment

If you want to understand where you stand with your software, team, and processes, I'm happy to take a deep dive and do some due diligence. I will then explain the situation, suggest what to improve and what to maintain, help set your strategy, goals and roadmap, and answer any questions you may have.

Free consultation

I offer one free consultation to every potential new client. So if you want to figure out if it makes sense to hire me, or simply want some quick advise, write to me, and I'm happy to jump on a call or exchange some emails at no charge.
