I am the Founder of Nurl, a company building an end-to-end platform for the Tabletop Role-play game industry. BMD has provided such a strong foundation from the beginning that I immediately gained my first early adopter using the playbook's provided. More importantly, it helped me to realize many gaps and areas I had wrong in my original (pre-BMD) canvas. Absolutely worth every penny.

If you're interested in entrepreneurship, forget going to Harvard Business School (FYI, I am an MBA graduate of HBS). Apply these concepts instead. Had I done so, I know I would have saved myself much time, money, and the attendant dead brain cells.

Before this program, I had goals set, but, I didn't have a clear understanding of how or when I needed to achieve those goals.

This program not only changed my approach to building my startup, but it made sure I was focusing on loving the problem and not the product, and constantly reminding myself that the product is the whole business model and not just the MVP itself.

BMD really expanded my notions of what is possible and changed my thinking regarding the whole process of starting a business. The information was communicated clearly and in a way that retained my interest as well as kept me interested in continuing.

I'm using the BMD to stress my business model. The BMD taught me to test my idea before going ahead and implement it.

I heard about BMD through a friend and I applied and got in. The biggest takeaway I got from BMD is getting to learn from other founders and hearing their stories and seeing just how possible it is. They're not any different than me, if they can do it, I can do it.

I bought Running Lean when a client was transitioning from consulting to a product firm. Now I'm using it to inform my own transition as I co-develop an app. While the canvas is good on its own, it's the well thought-out process I really appreciate (Fermi estimates, customer factory, customer forces canvas, etc). The videos are short, punchy and useful. Great stuff!

I'm a growth consultant focused on helping startups design scalable business models at LongBridge Growth. Participating in the Business Model Design Challenge Program with Ash Maurya was a game-changer. The structured, iterative approach helped me move from assumptions to validated insights faster than ever. What stood out most was how seamlessly the framework guides you to uncover real customer problems before building solutions. It’s a must for anyone serious about building businesses that work in the real world.

I'm Hunter from China. I want to have my own business so that I can work for myself. BMD teach me a great way to start with.

i am trying out different ideaas. BMD helped me with an structured approach.

Hello all, I am engineering professional with background in scientific computing, working on Saas product for clinical community. The BMD framework helped me gain clarity and identify how & where can I prioritize efforts and iterate quickly.

The BMD masterclass was an eye-opening experience. It gave our team the tools and structure to turn our affordable housing concept into a viable, scalable business model. The framework helped us think critically about our value proposition, customer segments, and revenue streams while keeping our social mission at the core. I’d highly recommend this course to anyone looking to make a real-world impact through innovative business design.

Im a business consultant, helping clients to gain clarity on some of the ideas they have. BMD has helped me exactly with that, gaining clarity on how to think about this ideas so they can become workable. The video lessons, and the short lenght of them, makes the whole experience very pleasable.

As the founder of elo and now elo works, I’ve been building a new business to sell standard clothing—T-shirts, polos, hoodies, and jackets—targeted first at tech companies in Pakistan, and eventually to businesses around the world. Going through the Business Model Design framework has been a game-changer. It helped me move from a broad, scattered approach—targeting anyone who wanted customized clothing—to discovering a clear, focused niche. Tech companies in Pakistan are a low-hanging fruit: they value quality, they have the budget, and they’re actively looking for corporate wear and gifts. I might have missed that insight without this process. If I had to highlight one thing, it’s the structure of the program. Absolutely brilliant. It forced me to slow down, think deeply, and answer the questions I didn’t even know I should be asking. Whether this business succeeds or not, I know I’m making more informed decisions—and that’s invaluable.

I am reviewing materials to be used as part of a company intrapreneurship program. So far, I like BMD and see how it can help us to reach our growth goals.

Hi! I'm Ricardo Esteban CEO and Founder of HitchGuardian. So far BMD has helped me understand the importance of bulletproofing my business plan. This understanding comes with perks like allowing me to focus and narrowd down into the key pathways to success. I'd like to highlight how easy it is to get into it and how Ash keeps the viewer engaged with valuable info.

I am applying BMD to my company, Wellstrack! There are so many great aspects of the BMD masterclass, I enjoyed the structure of the models and the ease of use. It was great to have built-in templates to help calculate ARPAs, the customer traction map, etc.

The Program gave me the clarity to refine my business idea by focusing on the problem rather than the solution, helping me identify a more strategic customer group through tools like the Lean Canvas and Traction Map. The biggest takeaway was understanding that new problems worth solving come from old solutions, which has reshaped how I approach customer discovery and product validation. I would definitely recommend this program to any entrepreneur looking for a structured and insightful way to build their business.

I am learning quite a lot as a beginner to a business start guide. its really unique and up to date with technology.

*** I highly recommend the 30-Day Business Design Model Class.*** The class provided a clear framework for crafting a fail-proof business plan. What stood out the most was the structured approach that allowed us to validate our ideas and test success before investing significant time and resources. The model was comprehensive yet straightforward, breaking down complex concepts into manageable steps. It offered a guided process that eliminated guesswork and inefficiencies, saving countless hours of trial and error. The emphasis on testing and validation me the confidence to move forward with an informed strategy. This training simultaneously built a business plan with a validated roadmap to success. The tools and techniques provided will undoubtedly help me make better decisions and allocate resources effectively. This training was like a breath of fresh air. My stress level has decreased tremendously. I highly recommend this training to anyone developing or considering starting a business.

BDM is the construction of mental models of estimation in three points: Desirability: the story that we tell ourselves through an elevator pitch Viability: the robustness of the financial model, adapted to the size of the target market, via the "customer factory" Feasibility: the traction achieved through the roadmap These mental models make it possible to present your economic model in a clear and concise manner, in order to validate it over a 90-day cycle.

I loved how it walked me through the process of starting and maintaining a business and taught me stuff you wouldn't find from independent research.

I will be using the information obtained in the class to pitch for funding, and explain how I will scale my business. The BMD masterclass gave me the confidence to pitch the problem I am solving with my business.

It has helped me align my pricing strategies and expenses with the needs of the market, ensuring that my business is financially sustainable. And I’m identifying critical partnerships with local organizations, athletes, and community leaders who can support the execution of my mentorship programs and sports training initiatives. The best thing about the BMD Masterclass was learning how to break down my business into its essential components and see how they connect. The most valuable takeaway is the emphasis on understanding customer needs and tailoring my value proposition to meet those needs effectively. This insight has shaped my approach to designing my business, helping me create a more impactful and customer-centric plan.

I’m currently exploring business ideas, and Ash’s 120DS course has been incredibly impactful. The biggest takeaway for me was to "love the problem, not the solution." Ash’s guidance on problem discovery and selling before building has completely transformed my approach, giving me the confidence to move forward.

Ash provides compelling, actionable guidance for applying Lean principles to a startup. His startup canvas changed the way I think about my own startup.

If you're considering building an application using Lean methodology, you are wasting your time by not following the path Ash has laid out.

Ash has a magical ability to distill the art and science of being a successful entrepreneur into simple, practical, and highly effective practices. It's a masterpiece of depth and simplicity.

Ash's approach is one of the few that I have seen that truly reflects the reality of my experiences over my 40-year career of entrepreneurship, innovation, and new product creation.

Ash has laid out a clear compass for anyone to validate their ideas, solve real problems, and create a successful business. 

Lean concepts are exciting but it's hard to know what to actually do. Ash not only gives advice but makes it practicable.

I am a founder who went through the Leanstack program 3 years ago with my two cofounders. We are very thankful to the program - especially now that after three years it's finally paying off. The only way we would have gotten traction is to constantly work off the customer factory and stay in that mentality. Thank you for instilling that in us! We fully benefited from the program and the toolbox. The Traction Roadmap combination is a game changer and in showing us "true north" for our product. We refer back to the Customer Factory very often to understand the viability of the solutions we are designing- particularly if we can build a reproducible system to deliver value at a price point. These tools combined with the Lean Canvas are incredibly powerful and I highly recommend the whole suite as well as the accelerator program.

BMD was very helpful in assessing the viability and feasability of our product, and helped us generate a more unique product that will hopefully be more successful than initial iterations.

I spent nearly a year working on an idea and realized it was not going anywhere. That's when I stumbled upon Ash's lean canvas concept. I promptly purchased his book Running lean, which led me to his tools on Lean Foundry and then subsequently to sign up for this course along with a coach. The biggest benefit for me was the program helped me avoid starting on an idea that later proved to be not something that my customer segment was interested in. As part of the program, I was also assigned a coach. And it was the coach who reinforced the concepts. When I thought I was ready, the coach pushed back and told me I was not. That was really helpful. If you are at an early stage of your startup or idea, I would highly recommend Ash's articles, the book, tools, and this course.

The Business Model Design (BMD) framework is applied at Frezit to ensure a holistic approach to our business strategy, focusing on the critical elements that drive our value proposition, customer engagement, and overall business sustainability. 

The hands-on approach and insightful guidance provided us with the tools to refine our business model, identify key metrics, and optimize our strategy for success. The hands-on approach and insightful guidance provided us with the tools to refine our business model, identify key metrics, and optimize our strategy for success.

The concepts teach founders and potential founders to view their ideas from the perspective of stakeholders and focus on determining the value in solving the problem rather than the solution itself. The training emphasizes actionable steps and adjustments to prevent founders from falling into analysis paralysis. I will utilize these concepts for several of my ideas in the ideation stage.

I have learned so much. The process helped me answer questions about my business path, calmed my spirit as an entrepreneur, and showed me that I am certainly not alone in the world of creatives.

I taught my Entrepreneurship Class, using the Leanstack portal. The portal functioned beautifully. The students found it intuitive and easy as well. I would wholeheartedly recommend LEANSTACK.

 BOOTSTART has THE best curriculum on the internet when it comes to early-stage startups. It's comprehensive, highly practical, focuses on principles instead of jargon, and the step-by-step layout makes the content easy to follow. I would highly recommend it for both founders and coaches alike.

As a teacher, mentor, and entrepreneur, I identify with Ash's approach. It's the best way to reach a successful destination and not waste resources. 

Really great content. The best on business model design that I've experienced. Loved it so much that we brought it into our University to train future entrepreneurs.

I read everything Ash writes. Why? Because he regularly and repeatedly helps me become a better entrepreneur. I've bootstrapped, built and sold a million-dollar startup, but still have much to learn. Recommended!

Fantastic book & toolset

It has given such clarity and insights as an entrepreneur. I hope more people can find this treasure!
