• Solving Industry Problems: Cash is tight. Big companies are moving at what feels like a snail's pace as they review a worlds worth of innovation and think about what's next for them. This takes forever, and it's no time to focus on saving the world. If you want to sell your product to an established corporate, the best way is to have a product that solves an urgent problem they are actively feeling pain from. Anything short of that is a one way ticket to the innovation department, which probably moves slower than the rest of the organization. Great examples in FoodTech are those solving for supply chains in current crisis, like eggs and chocolate.

• Precision Fermentation Infrastructure - I say this in every one of these articles, but there are two problems here. The world has limited capacity today for precision fermentation for food. As more food is fermented, there will be a capacity crunch. More importantly, what's available today is the wrong infrastructure for scale. If it seems like what's out there is fine for your needs, you either have a very high value product or you haven't fully thought through scale. 

• Food as Medicine - we're focused on high value, low inclusion ingredients. Not much checks those boxes better than low inclusion ingredients that are produced and regulated as food but have clinically backed pharma grade functional claims associated with them. Many consumers are buying on front of pack claims vs ingredient decks, and some of these ingredients focused on things like inflammation and gut health pack a huge punch at a great margin without requiring facilities to be built from scratch to get there.

Carlota Ochoa at Extantia Capital

• Energy Transition: We need to accelerate electrification efforts across long duration energy storage and EV charging infrastructure.

• Sustainable Solutions for Data Centers: Their demand is rapidly growing and their environmental footprint should be reduced as much as possible

• Adaptation and Resilience: Adaptation solutions to help nature and human beings build resilience against climate change (water tech, desert tech, and other types of technology to map and track our natural world are included here, too)

• Improving and Decarbonizing Middle- and Last-Mile Logistics: Freight is about 30% of transportation emissions today, and these emissions are expected to surge 30% over the next 5 years in the world’s top 100 cities (and double by 2050). In transitioning to electric and light-electric vehicles for this work, attractive categories for Streetlife Ventures include operations, management, and predictive maintenance platforms to streamline fleets, increase efficiencies, and lower operating costs. 

• Decarbonizing Building Operations: 60% of emissions in dense cities are from buildings, and - in developed economies - 70% of those emissions come from building operations. At Streetlife Ventures, we’re interested in solutions that offer novel financing solutions to this difficult sector, and/or offer outsized savings potential compared to upfront cost.

• Adaptation Technologies Given Climate Impacts Today: Globally, extreme weather events have led to a 500% increase in natural disaster hard costs since 2000, and threaten $4 trillion in corporate assets by 2030. To reduce these risks, we’re interested in decision enablement and intelligence platforms, physical interventions and products, and finance and insurance products. 

• Creating Cleaner, More Stable Energy Sources for Urban Areas: Tripling the global installed capacity of renewable power by the end of the decade is identified as the most important lever to reduce carbon dioxide emissions by 2030. This is especially critical in American cities, where on average ~70% of energy is “dirty” (e.g., produced by coal or natural gas). The American energy grid is at its weakest (recently graded at a D+ by the  American Society of Civil Engineers), demand growth over the next 5 years is expected to be 10X that of the last 10 years, and regulatory complexity consistently delays new project development.

• Water Intelligence: Water intelligence is crucial as 90% of climate change will be experienced through water while water pricing does not provide accurate supply and demand signalling. Holistic data solutions for water quantity and quality are needed for resource insights, forecasting and management.

• IoT for Heavy Industry: Industrial manufacturers prefer improving efficiencies in existing processes over implementing new ones. We are excited about a combination of proprietary data (via IoT) and AI-driven optimisation, especially for heavy industry.

• Energy Flexibility within the Built Environment: Flexibility in the built environment is essential as the roll-out of energy infrastructure is exponentially growing. Linking assets with each other as well as the grid and enabling flexible energy trading gains more relevance.

• Coastal Resilience Technologies: I’d love to see more startups building solutions to help vulnerable coastal locations in the fight against climate change. This may be surrounding potable water, natural disaster defence solutions, or better infrastructure to adapt to climate change. 

• Chemical Clean Up Technologies: Helping remove chemicals/ contaminants from soils or water. This could be bioremediation solutions for oil spills, PFAs or toxic chemicals that harm humans and mammals. 

• Green Port Side Solutions: Finding ways of making port operations cleaner and helping with the infrastructure needed to make maritime greener.
