It gets better and better in time.

In the initial chapter, there's not much about actual bootstrapping. The author is far more concerned about identifying & pursuing correct product opportunities - which ofc makes much sense. However, there are tons of books on that. In time there's more & more focus on bootstrapping, frugality, and priorities - the advice is practical, reasonable & generic enough for pretty much any software-based business. The most interesting chapter is probably the one about exit options - reasonably detailed & something you don't find in every 2nd book available.

It's definitely not a perfect book - some simplifications are irritating (e.g., when the author focuses too much on technology), the initial part is maybe a bit too repetitive over classics, but in the end, there are so few books on bootstrapping businesses & startup solopreneurship, that I recommend this one anyway.

4.4 stars, but I have a good mood today, so why don't we round it to 5.

It's a decent book if you are a complete newbie to building companies. Ideal for people still in their job, and contemplating starting a new company.

Some sections are insightful (especially those around identifying a niche and building product for early audiences).

Enjoyed it but dry at parts

Enjoyed the book, with the direct and practical language, but found it dry at parts. I think it could’ve benefited from more of a narrative around FeedbackPanda (more fleshed out stories related to learnings in book).

A must to read book for SaaS founders

Zero to Sold is a very practical guideline for bootstrapping a SaaS business. Arvid shares his learnings and experiences very openly to the reader. As he says at the end of the book Arvid has written this book to someone who is in his place five years before he sold his successful bootstrapped SaaS business, Feedback Panda.

I recommend this book to anyone who has started or thinks about starting a SaaS business.

I'm a fan of the author's podcast and that's how I get to know this book. Right now, I'm at the beginning of my journey to become an indie developer. I picked up this book hoping to learn from his experience to bootstrap my own SaaS.

What I like
- Very detail. When he says "zero to sold", he means it.
- He provides practical advices, not just some theories.
- He backs his claim with his own experiences with his business and he discloses things that he can only imagine but have no real experience.
- His experience is on software which is very much related to what I do. We are both a programmer so it's so relatable.

What I don't like
- Too details. But the book is not at the wrong here, it's me. I'm way too early in my journey that most of things he shares is not at all applicable for me at the moment. By the time I need it, I'll probably need to read again. I'm sure I won't remember everything he said by then.
- His approach is audience first. My personal approach is product first. His approach is proven to be profitable but I just don't feel that I'm in the right state of mine to implement it. And knowing that I walk the opposite direction from what he recommends make me feel demotivated about my path.

Who should read this
- If you are already building a SaaS and want to take it to another level
- If you have a product and you want to sell it
- If you want to start a SaaS and you don't mind talking to people to validate your idea

I began reading this when the author was working on it publicly over Twitter. He wrote a series of blogs that eventually became this book! There’s so many good nuggets in here and I recommend it for any SAAS founder, product managers, bootstrappers, aspiring founders, etc. Main nugget for me was his tips on how to structure customer calls - where they are now, where do they want to be, what’s stopping them from getting there?

4 out of 5, I really liked it.

If you’re thinking about creating a Saas business, this is a book that I’d put as the third after Built to Sell and E-myth Revisited. Especially as it’s written in about different way.

What I found the most interesting were aspects related to funding and pivoting the idea how to describe and phrase what your business does. If you’re fairly familiar with niche and idea validation, the initial chapters might be a bit boring. Still the rest of the book provides a lot of input for a young entrepreneur.

The worst parts are related to tech. Some of them are geeky or even goofy and this book would benefit from having them removed. Does an entrepreneur really need to know that docker is the thing?

At the end you can find a part that covers exit options. This is a topic that is not discussed enough. I learnt a lot from it, especially the earn outs and malicious agents were covered from an interesting point of view.

Wanna build Saas, do yourself a favor and read this book.

I loved this book.

Arvid goes through every stage of the bootstrapped founder, with the backdrop of having built a successful bootstrapped SaaS with his girlfriend Danielle.

It is a great reference for anyone thinking about starting a SaaS or actively navigating their way through growing a bootstrapped SaaS.

The way he breaks the startup into different phases of growth (preparation, survival, stability and growth) is 🔥. It allows you to focus on any phase you are currently in but also explore the phases you are heading toward.

I have read many books on SaaS and this the top of my list for must reads.

I really liked the book for a really good perspective of the author(Arvid) on building and managing SaaS business in a bootstrapped, indie way. There are actually tone of resources about some topics covered, and when I was reading, I felt like I kinda new some stuff. But seeing it through the lenses of a small successful bootstrapper gave some more information and proved those techniques are fully applicable on a small scale too(relatively). In some places, I saw author going into too much details, but probably because the book was made for people like him(as he also wrote - 5 year-ago me) - small bootstrappers and engineers, trying to run their projects as effectively as possible.

Another book that repeats ideas, which have already been talked about by other authors.
The first part of the book would be the most benefitial for new founders. However, those ideas are in fact common place knowledge among Silicon Valley startups and are even available for free on places such as YCombinator’s website.
So it’s not really clear who the book is even aimed at, as SaaS founders will most likely be aware of the first broader part which talks about finding product-market-fit, while the latter part of the book goes into such specific details that would be relevant only for late-stage startups which are looking to make an exit.

A truly wonderful book that cuts right to the chase, crosses the t's and dots the i's. Very actionable and straight to the point advice that is evergreen and doesn't rely on specific tools (like other business related books).

If you are a person with a technical background and an entrepreneurial spirit (either already started a business or dreams to do it), I consider this book to be a "must read" one, because it speaks our language (in contrast to usual business books that speak in a general voice to appeal to a wider audience).

Zero to Sold is a terrific read, for tech (SaaS-based) startup founders. For others; not so much. It has plenty of information, the entire process actually, from setting up a bootstrapped business to selling it. But half of the book is relevant only to the SaaS startups.

The book might also be useful to others who would like to work primarily with startups. You'll understand how to handle various operations related to a (tech) startup and thus, prove to be an invaluable asset to the startup you're a part of.

This is well written and was recommended to me as I’m growing my own business. If it has a fault then it’s that it’s really, really focused on growing a software business (and doesn’t pretend to be otherwise). I think my colleague who recommended it didn’t quite realise how focused it was - if you have a business in another industry you want to grow, there’s useful stuff in here but you really have to root it out.

Basically I was reading the wrong book - a good one so I gave it four stars, but the wrong book!

I rated it 3 stars because it was extremely dull and gave details for every little step along the way. I’m not sure if providing such an in-depth book is useful for most people thinking of starting a company.

It is better to inspire them and give general guidelines rather than bore them with all these mundane details.

While sometimes a bit of a slog, this book gave a thorough guide to starting, running, and selling a bootstrapped business. Aspects include finding market fit, validating the solution and product, using third-party software, being responsive to customers, dealing with feature creep, finding the right pricing model, making it easy to onboard employees.

Absolutely required reading for anyone building a tech company

This is the best, most comprehensive, overview of building a tech company in 2020 and beyond. It covers absolutely everything you could wish to know in an engaging and thorough way. Must read!

Excellent book for anyone running or thinking about starting a tech business. You would benefit from knowledge in this book even if you are not in the SaaS business. I have gained many valuable lessons that I can apply to my tech services (cliowebsites.com) venture. Highly recommended!

Must read for entrepreneurs

Whether you are looking to start to build something or already have, this book is a must read. I would go on to suggest that people should start with this book.

This is a pretty complete guide in all the topics you come across when starting, running and selling a company. I would say it is more an overview of lean startup ideas rather than a
Visionary book. I will probably scroll through it again.

Top Buch für angehende Bootstrapper mit vielen hilfreichen Tipps. Inspiration findet sich in jedem Kapitel. Selbst spätere Kapitel bieten hilfreiche Tipps für Bootstrapper in einem späteren Stadium ihres Businesses.

Das Buch ist eine absolute Empfehlung!

Got about halfway through.

Very good in terms of information density for a business book. Just not all that relevant to me at the moment; I struggled to care about what Kahl was speaking about.

One I'll probably pick up again in the future.

Super basic book about founding a company. I recommend reading Running Lean or Lean Startup instead of this.
Some topics like how to measure market size are just opinions and no concrete advice.
Maybe i was expecting something else.

Great read

I loved about it that it doesn’t start (nor it continues) as a sell pitch through out the book. He’s concise:

- This is what we did
- This worked for us
- This didn’t
- Everything else I ignore.
