Two ways we work together.

01 For founders w/ early traction

Fractional CTO

You have a product gaining traction but no one to own the technical vision. I join your team part-time and own it with you.

Architecture, hiring your first engineers, and making sure what you're building is solid technically, architecturally, and when it matters most.

  • Technical strategy & architecture
  • Engineering team building
  • Product & technology roadmap
  • Technical due diligence
02 For agency owners · 3–30 people

Agency Mentor

Most agency owners face one of two problems: you can't create demand reliably, or you have demand but can't deliver it sustainably.

Everything in between (hiring, scoping, pricing) is tactical and solvable. These two are what actually keep you stuck. We focus there.

  • Demand generation & positioning
  • Systems for sustainable delivery
  • Team structure & scaling
  • Pricing & client acquisition
01 Fractional CTO 1–2 days per week  ·  3-month minimum, open-ended thereafter
02 Agency Mentor 3 sessions per month  ·  3-month soft minimum, cancel anytime
Hands on · Direct · No fluff

A grown-up way to start.

i.

Discovery call

A short call. We talk through what's stuck. If I can't help, I'll point you somewhere better. Promised.

ii.

Diagnostic

A focused first session to map the actual problem, not the one that's loudest. You leave with a written read.

iii.

Cadence

Monthly or weekly working sessions plus async access. Built around your team's calendar, not mine.

iv.

Hand-off

The goal is systems that run without me. We end when you're stronger, usually 6 to 12 months in.

About
Alex Gutjahr
Alex Gutjahr Berlin · since 2012

14 years of building.
Every mistake in the book.

I've founded, scaled, and sold software companies for over a decade. I've also run them into the ground, hired the wrong people, and made technical bets that cost me years.

I started my first agency in 2012. We built products for clients like Amazon, HUGO BOSS, and Daimler, became early movers in voice technology, pivoted into blockchain, and raised venture capital. At some point I burned out because I had no idea how to actually run what I'd built. Nobody teaches you that part. Not how to find clients, not how to keep good people, not how to say no to the wrong projects.

So I started over. Rebuilt my agency around speed and a lean freelancer network instead of headcount. Got honest about what I didn't know. And now I help founders and agency owners skip the expensive lessons I had to learn the hard way.

Chapters

A working biography.

I've run every flavor of business. Each one charges its own tax in time, money, or sleep. Calm is the one I'd choose again.

2012 — 16

Agency business

First agency. Voice tech, IoT, mobile. Amazon, HUGO BOSS, Daimler as clients. Learned how to ship. Never figured out how to run a business.

2017 — 20

Product business

Crypto & venture-backed. Pivoted into blockchain. Raised venture capital, scaled fast, burned out faster. The expensive lessons happen here.

2021 — 23

Venture business

Head of Engineering, Flowcarbon. Built and led the engineering org of an a16z-backed climate company. Front-end to back-end to chain.

2023 — now

Calm business

Speedrun Studio. A lean agency built around speed and a freelancer network. The bullshit-free version of everything I learned the hard way.

Questions

Frequently
asked.

Honest answers to the things people actually ask before booking a call.

What do you actually help agency owners with? +

Two things, mostly. Either you're not generating enough demand: struggling to find leads, close deals, and convince clients you're not a commodity. Or you have demand but you're working yourself into the ground trying to deliver it all. The tactical stuff in between (hiring, scoping, writing proposals) is easier to solve once the bigger issue is clear.

What does working together look like? +

For monthly mentorship: three 60-minute 1:1 video sessions per month, plus async review of the documents you share between sessions (outreach copy, proposals, sales-call recordings, delivery plans). I read them and leave comments. I don't sit in on live calls or co-work in the same doc. The goal is systems that run without me, not dependency.

What results can I expect? +

Honest answer: it depends. On what you're trying to fix, how quickly you implement, and what you're starting with. I can't promise you'll double revenue in 90 days. Anyone who does is lying. What I can promise is clarity on what's actually stuck, a concrete plan to fix it, and someone who's seen enough agency problems to help you avoid the obvious mistakes.

Is there a guarantee? +

Yes. If after the first paid mentoring session you feel like this isn't working for you, email me within 24 hours and I'll refund you in full, no questions asked. I'd rather you walk away than stay in something that isn't helping. Full terms in the Terms of Service.

What if I can't afford mentoring right now? +

Check out Selling Engineering, a course I built for exactly this situation. It covers how to sell your technical skills without feeling like a salesperson: positioning, pricing, closing, handling objections. If you're struggling with the demand side, start there.

How do I compete when clients can just use AI? +

You don't compete with AI. You compete with other agencies who are panicking about AI. The ones who win can articulate the value of experience, judgment, and accountability. AI can generate code. It can't own the outcome. If you're losing deals to "we'll just use AI," the problem is your positioning.

How is this different from business coaching? +

I've run the same business you're running. I've made the pricing mistakes, the hiring mistakes, the "yes to every project" mistakes. This is pattern recognition from building agencies for over a decade, not theory from someone who's never shipped a product.

Who is this for? +

Agency owners running teams of 3 to 30 people. Big enough to have real problems (hiring, delivery, pricing, burnout). Small enough that your decisions still shape everything. Solo freelancers should start with the course; 50+ person agencies need a more specialized operator.
