Applied Alchemy
The Startup CTO’s Field Guide to Building Technology Companies from Nothing
Congratulations — you’ve worked your way to the top of the engineering ladder. Your journey has ended. But your journey has just begun. The job that got you the title and the job you now have to do are completely different — and they’ll be different again in 18 months.
The startup CTO role transforms completely as the company grows — from coder to manager to director to strategist — and most founding CTOs are replaced by Series B not because of technical shortcomings but because they never develop the business fluency, communication skills, and self-awareness to navigate those transitions. Half of all founding CTOs are replaced not for technical failures but because they never closed the gap between what they could build and what they could communicate.
This book maps that transformation stage by stage. It begins with the decisions that feel permanent but shouldn’t be — your stack, your MVP, your first architecture — moves through the competitive engine of shipping velocity, and confronts the business acumen gap head-on: the communication failures, the board meeting disasters, the co-founder conflicts that end more CTO tenures than any technical mistake.
It addresses the AI disruption reshaping the role in real time: team compression, vibe coding’s promise and peril, and the new competencies every CTO now needs. It includes the parts no one talks about publicly — burnout rates that would alarm any HR department, the loneliness of a role where you can’t show doubt to anyone, and the growing movement to normalise CTO transitions as a sign of strength rather than failure.
Grounded in named case studies, quantitative benchmarks, and interviews with CTOs across stages and outcomes, this is the field guide for every stage of that transformation — from your first commit to the day you have to decide whether to step aside.

Frequently Asked Questions
-
What is Applied Alchemy about?
Applied Alchemy is a field guide for startup CTOs that maps the transformation from coder to manager to director to strategist. It covers the technical decisions, team building, communication failures, AI disruption, burnout, and leadership transitions that define the role — grounded in named case studies and quantitative benchmarks rather than generic advice.
-
Who is Applied Alchemy written for?
The primary audience is startup CTOs at every stage — from first-time technical co-founders writing all the code to experienced engineering leaders managing hundreds of people. It is also valuable for aspiring CTOs, VPs of Engineering, engineering managers considering the CTO path, and CEOs who want to understand what their CTO is navigating.
-
What topics does Applied Alchemy cover?
The book covers the four stages of CTO evolution, the CEO-CTO relationship, technology stack decisions, technical debt strategy, shipping velocity, deadline management, product collaboration, engineering metrics, board communication, team building, AI transformation, the transition away from coding, operating rhythms, burnout prevention, knowing when to step aside, and building a lasting legacy.
-
Is this book useful for first-time CTOs?
Yes — first-time CTOs are the core audience. The book starts from the assumption that most CTOs arrive in the role without formal preparation, covers the earliest decisions (choosing a stack, building an MVP, making your first hire), and maps the transitions that catch first-time CTOs off guard. It provides the playbook that does not exist in most organisations.
-
How is Applied Alchemy different from other CTO books?
Most CTO books are written by consultants observing the role or by former CTOs writing from memory. Applied Alchemy is written by a working CTO currently navigating the challenges it describes. It prioritises named case studies over anonymised anecdotes, quantitative benchmarks over generic advice, and honest discussion of failure modes — including burnout, isolation, and the reality that most founding CTOs are eventually replaced.
