How do you give every location on Earth an address?In this conversation, Chris Sheldrick – co-founder and CEO of what3words – explains the idea that turned a frustrating moment at a music festival into a global addressing system used by emergency services, delivery companies, governments, and millions of people worldwide.What3words divides the entire planet into 3m x 3m squares (57 trillion in total) and assigns each one a unique combination of three words. Instead of complicated GPS coordinates, you can simply say something like table.chair.spoon and pinpoint an exact location anywhere on Earth.In this interview, Chris explains:• The “lightbulb moment” that started what3words• Why the world needed a new global addressing standard• How the company went from idea → adoption across industries• The challenge of getting people to trust and integrate a new standard• How governments, postal systems, and emergency services use it• What AI changes about location technology• Why the goal is to make the what3words app obsolete• The weirdest ways people use what3words — including tattoosThey also discuss the bigger idea behind it all: what other “hidden standards” in the world could be redesigned if we started from scratch.Check out what3words:https://what3words.com/ https://www.linkedin.com/company/what3words/https://www.linkedin.com/in/chrissheldrick1/ More on Basis:https://www.buildbasis.com/ https://www.youtube.com/@BasisCapital https://www.linkedin.com/company/basiscapitalltd/ https://www.linkedin.com/in/harrietsgreenSubscribe for more conversations on rebuilding systems, incentives and public services.Timestamps00:00 Intro00:45 what3words explained02:08 Where the system has been most revolutionary03:59 Why many global standards never get questioned05:54 Creativity, founders, and new ideas09:07 Monetisation and business model13:31 Selling to governments17:27 What AI changes for what3words21:40 Mapping space, oceans, and extreme locations25:02 The future of location data27:19 What it’s like running what3words for 13 years29:13 The strangest uses of what3words

Building a company straight out of university comes with very real trade-offs.In this episode of Basis Points, Harriet sits down with William Moore and Ethan McNeil, co-founders of Consus Energy, to talk candidly about what it’s actually like to start a company early – without accelerators, without a safety net and while learning everything in real time.We cover:How they met at UCL and split roles as a two-person founding teamBuilding a company without YC, EF or external structureWhy energy startups are uniquely complex to buildHearing “no” repeatedly – and learning how persistence really worksThe unglamorous parts of early-stage building (cash, admin, outreach)Whether university is still worth itWhy more graduates are choosing entrepreneurship as the job market tightensThe role of self-belief, co-founders and proactive networkingThis episode is especially relevant if you’re early in your career, considering founding, or already building and wondering if what you’re experiencing is normal.Check out Consus Energy:https://www.consusenergy.com/ https://www.linkedin.com/in/william-moore-232394250/ https://www.linkedin.com/in/ethan-mcneil-9069b11b0/ More on Basis:https://www.buildbasis.com/ https://www.youtube.com/@BasisCapital https://www.linkedin.com/company/basiscapitalltd/ https://www.linkedin.com/in/harrietsgreenFollow for more conversations on rebuilding systems, incentives and public services.

What if landlords could become their own green energy suppliers – cutting carbon, lowering tenant bills and unlocking entirely new revenue streams?In this episode, Harriet sits down with William Moore and Ethan McNeil, founders of Consus Energy, to explore a radically different approach to the energy transition: distributed batteries, wholesale energy buying and real-time energy arbitrage.Instead of building more grid infrastructure, Consus Energy works with the existing system by installing batteries across property portfolios and linking them into a single, intelligent energy network. The result is that energy is bought at off-peak wholesale prices, stored locally within buildings, resold to tenants at a lower cost, and excess power is sold back to the grid during periods of peak demand.All without tenants or landlords changing their behaviour.In this conversation, we cover:Why billions of pounds of renewable energy are currently wastedThe economics of energy arbitrage and flexibility marketsWhy battery technology only became viable nowHow distributed energy stabilises the grid instead of fighting it“Change without sacrifice” in the energy transitionWhat the future of decentralised energy actually looks likeWhat a Consus Energy battery installation looks likeWhether you’re in property, infrastructure, energy, climate tech, or investing, this episode breaks down one of the most overlooked and commercially viable shifts happening in energy today.Check out Consus Energy:https://www.consusenergy.com/ https://www.linkedin.com/in/william-moore-232394250/ https://www.linkedin.com/in/ethan-mcneil-9069b11b0/ More on Basis:https://www.buildbasis.com/ https://www.youtube.com/@BasisCapital https://www.linkedin.com/company/basiscapitalltd/ https://www.linkedin.com/in/harrietsgreenSubscribe for more conversations on rebuilding systems, incentives and public services.

Private security has existed for centuries, but access has always been limited to the few.What if you could book a trained security detail as easily as ordering a cab or groceries?In this episode of Basis Points, Harriet sits down with Nick Sarath, Founder & CEO of Protector, to explore how on-demand executive protection and community-funded neighbourhood patrols are reshaping how safety is delivered.Nick breaks down how Protector makes executive protection easier to access and procure, and why the industry is ripe for better UX, transparency, and trust. They also discuss Patrol, Protector’s LA rollout for community-funded neighbourhood patrols, reactionary headlines (“Uber for guns”) and whether private provision can complement public services by reducing strain on limited resources.What you’ll learnHow Protector “productises” executive protectionPatrol: crowdfunding neighbourhood security + real-time visibilityPublic safety vs perception of danger (and why it matters)Building in legacy industries with consumer distribution + storytellingFounder lessons: shipping fast, experimentation and AI as a design partnerCheck out Protector and Patrol:https://protector.so https://patrol.so https://www.linkedin.com/company/protector-security/ https://www.linkedin.com/in/nicksarath/ More on Basis:https://www.buildbasis.com/ https://www.youtube.com/@BasisCapital https://www.linkedin.com/company/basiscapitalltd/ https://www.linkedin.com/in/harrietsgreenSubscribe for more conversations on rebuilding systems, incentives and public services.
