Christina Wodtke (Stanford lecturer · author, 'Radical Focus') — 'suddenly I understood the answer to "if it can destroy humanity, why do AI labs keep working toward it?"'
“I just finished the chapter on financial gravity in Eric Ries terrific book, and suddenly I understood the answer to "if it can destroy humanity, why do AI labs keep working toward it?" It's been a while since a book helped me understand the world I live in…”

Eric Brafford (Decision Signals Method · Advisor to executive teams) — 'once you see what he sees, you won't be able to unsee it'
“I read Eric's new book, and I've been smitten with it since. He outlines the concept of "financial gravity" — the force pulling our capitalist economy toward the short-term, self-centered, profit-only core that ultimately destroys great companies. He argues…”
- Sep 18, 2026 Preethi Nair
Preethi Nair (Keynote Speaker · Bestselling Novelist · Storytelling Expert) — 'This event was a masterclass in storytelling'
“This event was a masterclass in storytelling because... Eric Ries stuck to one theme, and every story he told brought us back to it. And this is one of the biggest mistakes I see people make when they tell stories in business. They have lots of stories. But…”

Sourav Kundu (Group PM, BrowserStack) — Incorruptible on why founders lose culture control: 'set it during the time of incorporation itself'
“Founders want to set the company culture but often they are not able to control it after a point when they lose control to shareholders / board unless they structurally set the company's direction differently. Recently came to know from a podcast by Eric Ries…”
- Sep 17, 2026 Jaap van Ede, PhD
Jaap van Ede, PhD (Editor-in-Chief, Procesverbeteren.nl / Business-Improvement.eu) — in-depth Incorruptible review: 'a kind of multi-layered firewall'
“Eric Ries calls the "shareholders first" phenomenon #FinancialGravity. His new book #Incorruptable about this, is full of business horror. But it doesn't have to be that way, and this makes the book hopeful! Eric Ries is best known for his book The Lean…”

- Sep 17, 2026 Liz McBeth
Liz McBeth (CEO, Armour Valve Ltd) — extends Incorruptible's citizens-vs-tourists frame: 'why we've come to assume they should have the loudest voice'
“Another idea from Eric Ries' Incorruptible that has really stuck with me is the distinction between citizens and tourists. We would never allow tourists to vote in our elections. That right, and responsibility, belongs to citizens because they have a lasting…”

Michael Sliwinski (Founder, Nozbe) — 'This brilliant book by Eric Ries… one of the best books of this year to me personally'

Tara Ceranic Salinas, PhD (Professor of Business Ethics · Lead Editor, Journal of Business Ethics Education) — 'Hands down the best business book I've ever read'

- Sep 14, 2026 Marcel van den Bosch
Marcel van den Bosch (CFO & CEO · Steward Ownership) puts Incorruptible on his summer list next to Toekomstbedrijven
“After The Lean Startup, Eric Ries turns his attention to mission-led companies — and the forces that can gradually pull them away from their purpose. The big question: how do we build companies that can remain true to their purpose over generations?”
- Sep 13, 2026 Christian Soschner
Christian Soschner (24K+ audience of investors & execs) pulls Eric's Sears line: 'It was taken over by a parasite'

Dana Mincer, DO (physician-led health plan founder) — Incorruptible 'gave me language for what I've believed for years: the metric is not the thing'
“I've been reading Incorruptible by Eric Ries, and it gave me language for what I've believed for years: the metric is not the thing. Fifteen-minute visits measure activity. They don't measure whether a mother felt heard.”
- Sep 8, 2026 Katie
'6 years at Meta has hardened me as a cynic, and this thawed me a few degrees'
“I found this a very hopeful book, and a much-needed balm for the despair I've (we've all?) been feeling about the corruption of society by way of unrestrained capitalism. There ARE people thinking about ethics in corporate America. There ARE (or so the author…”
- Sep 5, 2026 Adrián Moreno Peña
Adrián Moreno Peña (VP Technology, Worksome) — Incorruptible as the guide to stop a company you built with Lean Startup from rotting into what you never wanted
“I find poetic that the same person that taught so many people how to validate an idea and turn it into a business (with The Lean Startup) brings now the guide on how to not let that company rot and evolve into what you never wanted it to be.”
- Sep 5, 2026 Gabriele Orrico
Gabriele Orrico — 'A mission can survive its founder and still fail the people it exists to serve'
“A mission can survive its founder and still fail the people it exists to serve. … Who gets to challenge the interpretation without being accused of disloyalty? Because whoever controls what the mission means has considerable power over whom it serves.”

Esther Clark (Forbes contributor, Drucker Challenge winner) — 'You're not stuck in traffic. You are traffic'
“Just finished reading 'Incorruptible: Why Good Companies Go Bad and How Great Companies Stay Great' by Eric Ries, recommended to me by Steve Blank. … One line that stayed with me: 'You're not stuck in traffic. You are traffic.'”

Liz Barber FCA GAICD (ASX100 Risk & Transformation Executive) — 'Everything worth protecting will eventually need protection'

Vlada Bortnik (Marco Polo CEO) — 'I'm giving up the ability to stab my customers in the back'

Dr. Bettina Palazzo (business ethics expert, 2024 ICA Compliance Influencer) — 'Nothing new under the sun': Sol Price's 1975 employee promises rediscovered
“All of those ideas about more ethical companies have been with us for at least 100 years. And most of those companies were highly successful - until they somehow got kidnapped by mainstream capitalism and perished.”

'It is a book that fills you with hope and that greed is not good'
“It is a fascinating book with some really good examples of organisation that have stayed true to their mission, Eric also provides a playbook of how to do it and establish a new governance structure. It is a book that fills you with hope and that greed is not…”

'For the past nearly 60 years, we have fetishized shareholder returns at the cost of other stakeholders'
“For the past nearly 60 years, we have fetishized shareholder returns at the cost of other stakeholders. It turns out, elevating the interests of team members, customers, suppliers, and broader society, isn't just better for the world. In the long run, it's…”
- Aug 31, 2026 Jonathan T. Marks, CPA, CFE, MBA, NACD Board Fellow
Jonathan T. Marks (BDO partner, NACD Board Fellow) — 'Companies rarely go bad because someone evil showed up. They go bad because the structure quietly started rewarding the wrong things'
“Companies rarely go bad because someone evil showed up. They go bad because the structure quietly started rewarding the wrong things. Eric Ries calls that force financial gravity in his new book Incorruptible, and he is right about more of it than I expected.”
- Aug 31, 2026 Tony White
Tony White (Franchise Expansion Specialist, 25 years / 800+ stores) — 'Franchise systems don't usually go bad because something went wrong. They go bad because things went right'
“Franchise systems don't usually go bad because something went wrong. They go bad because things went right. Success creates a pull toward extraction, and it arrives one reasonable decision at a time.”
- Aug 29, 2026 Alberto Onetti
Alberto Onetti (Mind the Bridge) — Polaroid's post-1982 collapse as the textbook 'unusual failure' from Incorruptible
“Unusual failures don't come about as the result of ordinary reasons companies go under, competition, creative destruction, or replacement by a superior form of value creation. They're caused by something altogether different. Just as surely as physical…”

Jason Fagone (author, The Woman Who Smashed Codes) — 'Eric writes with passion and precision about the wrecking ball of big-money investing'

- Aug 25, 2026 Dave Kellogg
Dave Kellogg (Kellblog, EIR at Balderton Capital) — 'If the mission matters, protect it through governance, incentives, metrics, and ownership structures. Do it early.'
“It's a good book with several important ideas. The strongest is that good intentions and mission statements are insufficient. If the mission matters, protect it through governance, incentives, metrics, and ownership structures. Do it early. By the time you…”

Berry Schrijen, CFA (Group CFO) — 'Just finished reading Eric Ries's newest book Incorruptible. Highly recommended!'
“Just finished reading Eric Ries's newest #book #Incorruptible. Highly recommended! That said, one important nuance deserves more attention. Ries builds his framework on the assumption that every company has (or could have) a #Mission worth protecting; and to…”
- Aug 23, 2026 Serban Dinu
Serban Dinu (Founder, ROMO, Romania) — 'design ROMO astfel încât succesul să nu ajungă să distrugă fix lucrurile pentru care merită construit'
“Cum construiești o companie care să NU ajungă să-și piardă sau vândă sufletul atunci când începe să aibă succes? Nu e suficient să fi un fondator bine intenționat sau să ai niște valori scrise pe pereții din office. Dacă modelul economic, incentive-urile și…”
- Aug 22, 2026 Sudha Shankar
Sudha Shankar (Troo founder, India) — 'Losses are expensive tuition. Most founders pay the fee and skip the class.'
“Losses are expensive tuition. Most founders pay the fee and skip the class. The audit was us refusing to skip the class. The The Mom Test Book, Eric Ries's The Lean Startup, and Click by Jake Knapp and John Zeratsky kept me honest :)”

Jesse Hormachea (Fractional COO, Valdivya) — publishes 'Building an Incorruptible Company' essay
“Maximizing human flourishing in an organization is a direct path to success I recently finished Eric Ries' latest book Incorruptible. You may know him as the author of The Lean Startup. His latest drives straight at the heart of concepts I've always held…”

Gloria Adaka (B2B Positioning Consultant) — 'most startups don't die from bad ideas. They die from good ideas that never earned the right to scale'
“Three weeks ago, I couldn't have told you what "financial gravity" meant. Today, I can tell you why most startups don't die from bad ideas. They die from good ideas that never earned the right to scale. That's one of the biggest lessons I'm taking away…”

Isabell Springer, PhD (Founder/CEO, SHiFT) — 'Are incorruptible leaders born, or can we develop them?'
“I've been reading Eric Ries Incorruptible, and I keep coming back to a question underneath the ideas in the book. Are incorruptible leaders born, or can we develop them? Nature versus nurture. Corruptible versus incorruptible. We can build governance…”

Tyler Carey (Trellis) — pulls Incorruptible's GitLab example into a live compensation-transparency argument
“Eric Ries highlights GitLab in the book Incorruptible, and I immediately thought back to the trifecta of traits, specifically, transparency. They have their entire employee handbook available to the public, even their compensation philosophy.”

André Caldeira (CEO Grupo PROPOSITO, IBGC board-training instructor, Brazil) — pulls the Sol Price chapter into a governance essay
“Estou lendo "Incorruptible – Why Good Companies Go Bad…And How Great Companies Stay Great", um belíssimo livro escrito por Eric Ries, autor do famoso "The Lean Startup". Uma das primeiras histórias contadas no livro me inspirou para o texto de hoje: a…”

“Влітку 1975 року Сол Прайс прийшов на роботу й не зміг відчинити двері власної компанії. Замки змінили за ніч. За двадцять років до того він винайшов формат, який згодом поховає половину американського ритейлу, – магазин-склад із членством, де ціни тримаються…”

Derrick Boddie — 'A verified human generated product is gonna be like a super premium item.'
“Eric Ries said something on Digital Disruption with Greg Nelson that stuck with me: "A verified human generated product is gonna be like a super premium item." Think about that for a second. We're entering a world where the default assumption is that AI made…”

Enrique Burgos — Ries's 'física organizacional' aplicada a la traición corporativa (Spanish)
“Me acordé de esa imagen escuchando a Eric Ries, el de The Lean Startup, explicar en el podcast de Harvard Business Review por qué las buenas empresas acaban traicionando sus principios. Casi nunca hay malas personas detrás, dice, sino lo que él llama 'física…”
- Aug 14, 2026 Mohammad Mesgarpour
Mohammad Mesgarpour — 'most organisations don't fail because they run out of talent, ideas, or technology. They drift.'
“I've just finished the first half of Eric Ries' latest book, 'Incorruptible', and it's one of the most thought-provoking business books I've read recently. The central idea is uncomfortable: most organisations don't fail because they run out of talent, ideas…”

Mike Walsh (Straight Path IT Solutions) — 'the more people in the payout line, the harder it is to maintain the ideal'
“Just got done listening to Incorruptible by Eric Ries … at Straight Path IT Solutions - We're a very small privately held business and put values first in all we do. It's a lot harder the bigger you are, though. And from what I observe the more people in the…”

Pjotr Sillekens (biotech founder) — 'They drift because caring was never the mechanism. Intentions decay. Structures persist.'
“I'm reading Incorruptible by Eric Ries. His argument is uncomfortable in a useful way: companies don't drift because people stop caring. They drift because caring was never the mechanism. Intentions decay. Structures persist. So the fair question a customer…”

Colleen Hendry (Boailoop founder) — 'easily my favorite book I've read in quite some time'
“Incorruptible by Eric Ries is easily my favorite book I've read in quite some time. The stories alone are incredible, but what really stayed with me were the questions it raised about leadership, incentives, how companies lose their way, and how we make…”

Jay Friedman (adtech/martech industry veteran) — applying Incorruptible's trust thesis to martech M&A: 'is there a Costco or USAA of martech/adtech?'
“Reading Incorruptible by Eric Ries and watching our martech/adtech market recently (M&A, earnings) and there's an overlap. Vendors do so much work to acquire/retain business, but I'm wondering - is how brands/agencies *feel* when working with a vendor - where…”

Amanda Miller (product leader) — Incorruptible calls back to her call-center 'guardian angels' work
“I'm only half way through and there are so many moments of this book that made me sit up straight and, with my inside voice, scream, "Yesss! Power to the people!!" It reminded me of an early product effort where I productized the experience of a 400-person…”

Kuba Filipowski (Netguru co-founder) — in the AI era, 'the artifact is not the point' (Eric Ries)
“When people say 'I want to build an MVP,' they now think: 'Claude Code will build it for me.' Eric Ries says: the artifact is not the point. The author of The Lean Startup and Incorruptible: Why Good Companies Go Bad... and How Great Companies Stay Great…”

Jordan Stephens (Cohearity co-founder) — Salad and Go's collapse as 'a cautionary tale right out of that book'

- Aug 5, 2026 James DeVaney
'Purpose without power is just poetry'

Jenny Kassan (Senior Attorney, Jason Wiener PBC) — 'The book advocates for structuring a company in a way that legally protects it from the inevitable pressures of what Ries calls financial gravity'
“The book advocates for structuring a company in a way that legally protects it from the inevitable pressures of what Ries calls "financial gravity" – the deeply engrained instinct to concede power to those who control financial capital. Ries says financial…”
- Aug 4, 2026 Luca Leonardini
Luca Leonardini — Incorruptible's 'financial gravity' as the force pulling long-term value creation into short-term optimization
“Most companies don't set out to lose their way, but they do. And they do it by simply keep following what the market rewards. Eric Ries in his new book 'Incorruptible' calls this force financial gravity: the relentless pressure that turns long-term value…”

'A masterclass in corporate governance and long-term value creation'
“While you may know Ries for the "Lean Startup" methodology, what he delivers in "Incorruptible" is a masterclass in corporate governance and long-term value creation. He dismantles the tired dogma of short-term profit maximization and presents a compelling…”

- Aug 3, 2026 David Bauman
'Investors can purchase enough shares and then rob a corporation of its soul'

Jim Ritchie-Dunham (Institute for Strategic Clarity) — sitting with the honest challenge in Incorruptible
“An executive in Eric Ries' new book Incorruptible asked, in essence, 'If purpose-based companies really worked better in the long run than quarterly-profit-based companies, the market would have sorted this out by now.' That question stays with me. Not…”
- Jul 30, 2026 Justin George
Justin George (Aurora flooring company owner) — 'Turns out the pressure is the same at any size'

Kaley Cross Warner (sustainability practitioner) — mission-drift in the sustainability profession, named as 'corruption'

James Boyle (SR Inc., Dignity First Leadership author) — Incorruptible as the board-level system corporate-sustainability directors have been missing

- Jul 27, 2026 Melanie Steinbach
Melanie Steinbach (ex-CHRO McDonald's / Kraft / IBM) — 'it's because the system around them made caring expensive'
“Throughout my career, one pattern shows up more than any other. People want to do good work. They want to contribute. They want their effort to matter. When that instinct gets buried, it's rarely because someone stopped caring. It's because the system around…”

Chris Justice (Engenious Design) — 'If your organization's metrics don't fight each other, they aren't that good'
“If your organization's metrics don't fight each other, they aren't that good. Because that means they are too simple to accurately reflect reality. This is one takeaway as I read Eric Ries book 'Incorruptible'. He cites the example of an airline that had…”

Lyn Brown, ICD.D — how financial gravity weakens 'truth-telling systems inside an organization'

Daniel Franklin Gomez — 'Incorruptible by Eric Ries - 9/10… ethos plus integrity equals incorruptible'

Liz Rockett (Mission Lock Collective, ex-KP Ventures) — 'this applies extra to us' in healthcare
“He talks about purpose in a way that isn't all fluff, but as a key way to protect against the extractive instincts of investor owners. And he describes the effect that all this has on those of us trying to build something better — "under this constant…”
- Jul 15, 2026 Sarah Brinton
Sarah Brinton (BambooHR) — 'mildly obsessed with Incorruptible… nihilistic entropy attendant to capitalism'
“I am mildly obsessed with Incorruptible by Eric Ries. The book makes explicit a kind of nihilistic entropy attendant to capitalism (which I agree is the best of the imperfect economic systems) that I've sensed but not been able to name.”

'The most interesting analytic is what Ries calls false proxies, where metrics like average call-hold-time end up making the underlying service worse'
“The most interesting analytic is what Ries calls 'false proxies,' where metrics like average call-hold-time end up making the underlying service worse rather than better… What Ries proposes is to lock in the company's original mission from the start. But no…”

'A meaty book with lots of practical advice and a compelling business case'

'My favourite book I've read in years'

Dougal Shaw (BBC News / Business Leader) — 'Corruption breaks the logic of capitalism'

Dorie Clark (bestselling author, Duke Fuqua) on Incorruptible — 'A worthy sequel to The Lean Startup'

Slightly Smarter newsletter on Incorruptible: 'the design work that decides whether a mission survives its own success'
