Build the Damn Thing by Kathryn Finney, published by Portfolio in 2022 with a foreword by Guy Kawasaki, is a startup guide for founders who do not fit the stereotype of the funded tech founder. Finney built and sold the fashion site The Budget Fashionista, then founded the nonprofit digitalundivided to support Black and Latina women founders, and later the venture firm Genius Guild. She writes for women, people of colour, immigrants and anyone who starts without family money or a famous network behind them.
What is Build the Damn Thing about?
Finney’s argument is direct: the startup world was set up around one kind of founder, and everyone else is underestimated by investors, partners and sometimes themselves. Being underestimated has a cost, since money and introductions come harder, and it also brings strengths such as resourcefulness, grit and insight into markets others overlook. The book teaches readers how to use those strengths and get around the barriers.
The chapters follow the path of a company. Finney starts with the founder’s mindset and the decision to begin, moves to shaping and testing the idea, then covers writing a business plan, building a team, finding customers and refining the product. A large share of the book deals with money: bootstrapping, grants, loans, angel investors and venture capital, with frank advice on what investors look for and how bias shows up in the room. She also writes about protecting your mental health and building a support system.
What sets it apart is the voice. Finney writes like a straight-talking mentor, with humour, personal stories and hard truths about race and gender in tech funding. She has sat on both sides of the table as a founder and an investor, so the advice on fundraising is specific about what happens in meetings.
What are the main lessons for founders?
- Begin with what you have. Your skills, community and lived experience are assets. Use them to build a first version and find early customers before you look for outside money.
- Treat your community as a market. Underestimated founders understand customers that mainstream investors overlook. Gather proof of demand from that community to make your case.
- Know every number. Expect harder questions than other founders get. Prepare your unit economics, market size and growth plan until you can answer without notes.
- Match money to your goals. Venture funding suits companies that can grow very fast. Grants, revenue and loans suit others. Decide what you are building before you decide how to fund it.
- Protect yourself. Building while being underestimated is draining. Set up therapy, peers or other support before you hit a crisis.
Who should read Build the Damn Thing?
It suits first-time founders from groups that rarely get venture funding, especially Black and Latina women, at the idea stage or in the first year of a company. It also helps people who run accelerators, angel groups or diversity programmes understand what founders face. Experienced founders preparing a first institutional round will find the funding chapters useful.
Skip it if you already have a funded company and an experienced team. Much of the advice covers first steps you have already taken.
How do you put Build the Damn Thing to work this week?
- Write down every resource you already have: skills, savings, contacts, communities and time. Circle the three that give you an edge in your chosen market.
- Talk to five potential customers from the community you know best and record what they pay for today to solve the problem.
- Draft one page with your numbers: price, cost to deliver, how many customers you need to break even and the market size. Rehearse it out loud.
If grants fit your plans better than equity, the Fe/male Switch guide to EU grants for startups lists funding you do not have to give shares away for.
Where does Build the Damn Thing fall short?
The book is rooted in the US: the funding examples, investor culture and support programmes reflect American markets, so founders in Europe, Africa or Asia have to translate. Because it covers the whole path from idea to funding, each stage gets a broad treatment instead of a detailed one. Founders who want depth on customer research or deal terms will need more. For the customer conversations that should come before any pitch, read The Mom Test, and for term sheets, read Venture Deals.
