Peers Inc: How People and Platforms Are Inventing the Collaborative Economy and Reinventing Capitalism
Shows how idle cars, rooms and tools become the raw material for sharing platforms, and how to build one that grows safely, keeps its purpose and helps cut emissions while users save money.

1. Introduction
1 min 02 sec
If you own a car, a spare room or a drill, you are probably paying for things that sit unused most of the time. In Peers Inc, Zipcar co-founder Robin Chase argues that this idle capacity is the raw material of a new kind of economy, where a company builds the platform and ordinary people supply the goods and services. Her case is direct: when we stop buying everything and start sharing what already exists, owners earn, users save and the planet carries fewer emissions.
Uber and Airbnb are the famous examples, but the model stretches from GPS and the electricity grid to a French home-improvement chain and rickshaws in India. Getting it right takes more than an app. A platform has to make sharing easy, grow at the right pace, find money that protects its purpose and work with governments. Follow Chase’s reasoning and any idle asset, in your home or your company, starts to look like a saving or a business waiting to happen.
2. Turn idle things into a business people need

People lent each other cars long before any app existed, so why did a car-sharing company need to be invented at all? The answer reveals what separates a useful sharing business from a nice idea.
3. Grow your platform slowly to spot abuse early

A teenager’s birthday invitation went to every Facebook user, and a crowd arrived. New platforms risk the same chaos, and a second danger appears later, from users who understand the rules better than you do.
4. Pick funding that keeps your mission in your hands

The money that launches a platform can also steer it somewhere its founders never meant to go. Chase compares three sources, and the cheapest-looking one is not always the safest.
5. Tough rules can open doors for new platforms
1 min 32 sec
A Cold War military system and a famously hard taxi exam seem to have nothing in common. Both, in Chase’s telling, created room for platforms that millions now use without a second thought.
6. What big companies gain by opening their doors

A supermarket giant let a competitor review its strategy, and a hardware chain handed its customers a stage. A study of America’s most valuable companies suggests why such moves may soon be expected.
7. Share more to cut emissions and save money
1 min 31 sec
Governments have been slow to act on a warming planet, and a tax on pollution would not be enough alone. Chase looks to an Indian rickshaw service for a sign of what peers can do instead.
8. Conclusion
1 min 04 sec
Peers Inc rests on a plain piece of arithmetic. A car parked most of the day, a spare room, a roof that catches more sun than the house needs: each is value already paid for and going to waste. Chase’s argument is that the businesses worth building gather this wasted value and hand it back to people, and that doing so pays off in three ways at once. Owners earn from what they already have. Users save by not buying. The planet takes on fewer emissions.
The rest of her advice is about doing that well. Make sharing easier than borrowing from a friend ever was, open the doors in stages so you can see who tries to bend the rules, and choose money that keeps the platform faithful to its purpose.
For most listeners the starting point is closer to home. Notice what you own that rarely moves, and before the next purchase, ask whether access would serve you as well as owning. Zipcar began with one such question about a parked car, and Chase believes many more of those questions are still waiting to be asked.
About this book
What is this book about?
Most people have accumulated possessions beyond their real needs, and a lot of these items sit idle much of the time, such as a car parked for most of the day, an unused bedroom, or tools and appliances stashed away. Robin Chase, who co-founded Zipcar, argues that this idle capacity is the base of a collaborative economy in which companies provide the platform and ordinary people supply the goods and services. Chase explains what makes such a platform work. It has to make sharing easier than any informal arrangement, and it has to grow in stages so that problems and rule-bending users show up early. Its funding has to fit its purpose. She draws on Zipcar, eBay, Airbnb, Github, Kickstarter, GPS and Uber, and on large firms such as Sainsbury's and Castorama. The stakes reach past business. Chase connects sharing models to climate change, pointing to an Indian rickshaw service that cuts emissions and traffic. Readers get a clear way to spot unused value around them and a practical sense of how to build, fund and protect a platform that shares it.

Ever wonder how the collaborative economy could actually save the planet while making us more efficient? Robin Chase presents a truly optimistic solution to some of mankind’s biggest problems by focusing on the concept of excess capacity. It is refreshing to see a cofounder of Zipcar synthesize so much information into a framework that feels both accessible and revolutionary. The idea of 'Peers Inc' isn't just a catchy slogan; it is a viable business model for the future. While some might find her passion for the environment a bit much, I found it to be the heart of the book. The way she bridges the gap between individual creativity and corporate scale is brilliant. This is a great 101 for anyone looking to understand how the internet allows us to work together in ways we never thought possible. It’s a fun read that left me feeling hopeful about our collective future.
Show moreRobin Chase is a visionary who truly understands how idle assets can be transformed into massive opportunities for everyone involved. This book is a masterclass in understanding the world of sharing, with a special emphasis on transport that only a Zipcar founder could provide. She argues that when we switch from a buying mentality to a sharing one, the planet wins. It is a simple message, but the way she scales it into the Peers Inc framework is incredibly sophisticated. I loved how she highlighted the 'excess capacity' of our skills and knowledge, not just our cars or spare rooms. The writing is engaging and the tone is consistently optimistic. For those new to the collaborative economy, this is a must-read. It brings together so many different threads of the digital age into one clear, actionable vision. Truly an impactful read for the modern entrepreneur.
Show moreTruth is, this is one of the most optimistic solutions to our current climate crisis I’ve encountered in years. Robin Chase doesn't just talk about the problem; she offers a functioning business framework to help solve it. By leveraging excess capacity, we can reduce emissions and make money at the same time. The book is an excellent synthesis of how digital technology allows us to scale individual efforts into global movements. I found it very fun to read and incredibly thought-provoking. Even the chapters on policy were interesting to me, as they show the broader implications of the 'Peers Inc' model. It’s a great 101 for anyone who wants to understand why the world is moving away from ownership. If you're interested in web community startups, this mindset is essential. Highly recommended for those who want to see the big picture of the collaborative economy.
Show moreAs someone who has always been fascinated by platform-based startups, I found this to be an excellent knowledge synthesis. Chase does a fantastic job of taking disparate pieces of information and stitching them into a cohesive narrative about why owning things is becoming obsolete. The book is cleverly divided into the building blocks of excess capacity and the actual execution of those ideas. Truth is, building a platform is an incredibly difficult endeavor, and while this doesn't offer a step-by-step manual, it provides a vital mindset shift. I particularly enjoyed the sections on crowdfunding and how it empowers the 'peer' side of the equation. However, I did find the chapters on government policy and universal health care to be a bit of a detour. They felt out of place in a book that was primarily about business models and transportation innovation. Still, the quality of the content is high.
Show moreFinally got around to reading this after it was recommended on a tech blog, and I have to say it’s a great 101 on the new business model. Chase provides a really useful organizational framework for anyone interested in creating a web platform. The case studies are varied, though I agree with other reviewers that some examples are starting to feel a bit dated. What stands out is her ability to explain how small peers can do things that large corporations simply can’t. The synthesis of information regarding equity-based crowdfunding was particularly useful for my own startup research. To be fair, the book does get a bit preachy toward the end regarding environmental issues, but her passion is contagious. It’s a solid four-star read for the way it redefines our relationship with stuff. Just don't expect a technical manual; it's more about the philosophy of the platform.
Show moreTo be fair, the book does a remarkable job of stitching together disparate threads of information into a cohesive narrative. Robin Chase uses her experience with Zipcar to explain how the combination of institutional power and peer participation creates something entirely new. I found the content quality to be high, even if I didn't agree with every one of her political conclusions. The idea that everyone wins when we share resources is compelling and well-argued. My only real gripe is that the book ignores the downsides of the shared economy, specifically regarding the erosion of worker rights. She mentions it briefly at the end, but it deserved more focus. Regardless, the book is fun to read and provides a very helpful framework for understanding how the internet is changing collaboration. It is a very insightful account of the modern sharing landscape.
Show moreSeven years is an absolute eternity in the world of technology and startups. Picking this up today, I found that many of the examples provided now feel like ancient history, which is a shame because the core message is still quite relevant. To be fair, if I had read this alongside titles like Macrowikinomics when it first debuted, I probably would have been more impressed by the foresight. The book does a solid job explaining the sharing mentality, yet it often wanders into territory that feels a bit naive regarding actual business execution. I appreciated the discussion on how the peer economy can become a victim of capitalization, but the author's tone occasionally comes across as slightly elitist. It’s a decent overview, but it lacks the academic rigor I was expecting from someone with her level of industry access. Not a bad read, but definitely showing its age.
Show moreThe central premise of leveraging excess capacity—what Chase calls the 'Peers Inc' model—is undeniably brilliant, yet the execution details feel a bit thin. I wanted to love this because I’ve heard her speak before, but the book feels a bit far-fetched in its grander ambitions. For example, she paints a beautiful picture of a peer-led future but fails to address pressing social concerns like the lack of a safety net for gig workers. In my experience, these platform-based structures can be necessary evils rather than the pure utopia she describes. The chapters on climate change were interesting, but they dragged the overall pace down. It’s a good book for a general overview, especially if you use services like Blinkist to get the highlights, but it lacks the deep-dive business analysis I was craving. It’s a bit too much 'big ideas' and not enough 'how-to'.
Show moreNot what I expected from the cofounder of Zipcar, as the tone frequently veers into something that feels a bit elitist and naive. While I appreciated her insight into the transport sector, her broader observations on the sharing economy felt like they were written from a bubble. She has a great slogan in 'Peers Inc,' but the book often prioritizes her own personal views over academic rigor. The discussion on climate change was fine, but it felt like she was trying to solve the world's problems without a clear plan for execution. Frankly, the book is at its best when it sticks to the mechanics of excess capacity and building blocks. When it starts lecturing on government policy, it loses its way. It's a decent read for the core business concepts, but you have to filter out a lot of the 'preaching and pleading' to get to the gems.
Show moreLook, I came here for a business book about the sharing economy, not a manifesto on climate change and government policy. While the first few chapters on how Zipcar leveraged idle assets were insightful, the book quickly devolved into preaching. To be frank, the research felt weak when it came to backing up her more radical social claims. She describes a model that would further erode our privacy as individuals, which she mostly brushes aside. It felt like she didn't fully grasp the complex social issues like health care that she tried to tackle in the later chapters. Instead of a rigorous analysis of the Peers Inc model, we get a lot of pleading for a greener world. The passion is admirable, but the execution of the book is messy. I wanted more data and fewer personal views. It was a frustrating experience for what could have been a great case study.

What is the main idea of Peers Inc by Robin Chase?
Chase argues that much of what we own sits idle, and that this excess capacity can power a collaborative economy. A company builds a platform that makes sharing easy, and ordinary people supply the cars, rooms or skills. When people move from owning to sharing, owners earn money, users save money and fewer emissions are released. She shows the model at work in Zipcar, Airbnb, GPS and a rickshaw service in India.
What is excess capacity in the sharing economy?
In Chase’s terms, excess capacity is anything owned that is not used all the time or not used to its full potential. Examples include a parked car, a second apartment, or tools and appliances in storage. She sees it as the foundation of any sharing business, but only half of it: a platform must also make the sharing simple, as Zipcar did by showing when every nearby car was free.
How should a new sharing platform launch and grow?
Chase recommends adding users gradually rather than opening to everyone on day one. Slow growth lets a company fix problems through trial and error, as eBay did when it added ratings and reviews. It also reveals power players, users who exploit the rules, like the real-estate professionals who rented whole homes on Airbnb until the company removed their listings.
How should a peer platform be funded?
Chase describes three routes. Private investment can push a platform toward shareholder value and cost founders control, which is why Github avoided it for four years. Public funding suits utility-like platforms such as GPS, WiFi and the internet. Crowdfunding lets founders keep control because backers get no equity, as Caroline Woolard showed when Kickstarter covered most of the cost of launching Trade School.
How can sharing platforms help fight climate change?
Chase argues that emissions must reach net zero by 2050 and that government action, including a carbon tax, is not enough alone. Peer models could change farming, food distribution and public transport. Her example is G-Auto in India, founded by Nirmal Kumar, which matches rickshaws with passengers so drivers stop circling for customers, reducing both emissions and traffic jams.
