Review

“In my work mentoring startups and navigating VC partnerships in Silicon Valley, I constantly see founders struggle to present a coherent data narrative to investors. From Data to Dollars is exactly the pragmatic, no-hype playbook early-stage companies need to stop guessing and start building data foundations that actually drive growth and secure funding.” (Aggie Krajewska, Founder and CEO at SF Startup Labs (ex-Google))

“From Data to Dollars is the roadmap I never had. Piotr writes from the reality of startups and growth-stage companies—where time is limited, teams are small, and data is messy. It will help you pick the right problems, build trust in your work, and translate analysis into impact.” (Matt Dancho, Founder and CEO, Business Science)

“This book is a masterclass in making startup analytics practical and impactful. As a technical professional, it gave me a fresh, deeply valuable perspective on the business decisions behind the data we build.” (Bartosz Konieczny, author of “Data Engineering Design Patterns”; Freelance Data Engineer)

“I constantly see companies rushing into complex AI initiatives without building the right data foundations first. From Data to Dollars provides the exact pragmatic roadmap startups need to build scalable, revenue-driving analytics from day one. Piotr brilliantly translates complex data engineering and machine learning concepts into actionable business strategies. It is required reading for anyone looking to bridge the gap between technical infrastructure and actual bottom-line results.”(Pawel Jamer, Data Science Manager and Lecturer)

“Working with companies of all sizes across multiple industries, I constantly see the same mistake: burning budgets on overhyped, shiny tools. From Data to Dollars provides a perfect framework for founders and first data hires who need to wear multiple hats and single-handedly build a data department from scratch. It is a must-read for creating a lean data function that actually delivers ROI.” (Michal Debski, Co-CEO, Astral Forest)

“Too many startups treat data as a technical problem instead of a business advantage. From Data to Dollars shows how founders can turn raw data into compelling narratives for investors while gaining a deeper understanding of their own business.” (Kasjan Krasinski, Finance Advisor to Bitcoin startups and author of “Broken Prices”)
