Best Environmental Startups to Watch in 2023

Green startups are on the cutting edge of new technology while also helping the world at large recover from years of overuse. While sustainability can help every human hope for a better future, these companies are taking action on green practices that will help everyone in the years to come. Here are the top environmental startups to watch out for, along with detailed information on what they do, their funding, and how they are changing sustainable business.

 1. Biome Makers

Recovering soil health is an essential step towards a more sustainable future. Biome Makers, a startup founded in 2015 by Alberto Acedo and Adrián Ferrero in Silicon Valley, is dedicated to improving the world’s soil health — one farm at a time. Since its inception, the biotech startup has prioritized recovering soil health by supporting farmers around the world to enhance both their farming and business practices. Detailed reporting and analytics provide farmers with soil fertility, biodiversity, and health stats to help them make informed, impactful changes.

Today, Biome Makers is implementing AI technology supported by their expertise in agronomy (the science of soil management and crop production) to create a virtual assistant that is able to help farmers increase crop yields and quality.

2. Aurora Solar

As the demand for alternative energy sources increases, solar energy companies are more popular than ever. Aurora Solar provides solar energy companies with software to design and sell solar paneling systems for customers remotely. With the US government planning to invest nearly $2 trillion into the industry, the sky's the limit for sustainable startups like this.

3. Treeapp

What if you could plant a tree across the world, from your phone in just one minute? With Treeapp, you can. This ultra-sustainable startup was created by three London Business School graduates — Godefroy Harito, Jules Buker, and Leo Ng — in 2019. The app officially launched on April 22, 2020, coinciding with Earth Day. Within its first year, it planted 230,000 trees across the globe. Customers simply select a reforestation project to support, plant a tree, track the global impact for free due to Treeapp’s partnerships with businesses and organizations around the world that are equally passionate about sustainability.

4. EcoCart

EcoCart is a browser extension startup company that allows users to offset their carbon emissions for free from select businesses. Partnering with over 10,000 businesses such as American Eagle and Glossier, customers who choose to offset their emissions using EcoCart are rewarded with EcoPoints to receive prizes and help provide clean water and trees around the world.

This eco-friendly startup, founded in 2019 by Peter Twomey and Dane Baker, claims to have offset 4 million pounds of carbon dioxide (CO2) emissions, saved more than 8,000 trees, and helped power more than 700 homes thus far. In addition to EcoCart’s browser extension, the startup offers environmental accounting services that help businesses track their own carbon emissions.

5. Bluebird Climate

Bluebird Climate is on a mission to help brands across the world measure their sustainability practices to open partnership opportunities with other businesses. The software focuses on the consumer products industry, which is responsible for a large number of carbon emissions let go into the atmosphere. Bluebird hopes to decarbonize the industry by giving consumer brands the ability to produce and market products that have little or no carbon emissions.

Their end goal is to help these consumer brands attract consumers that care about sustainability and business green practices. Brands will be given an in-depth analysis of the carbon and waste footprint of their products and compare it to similar products in the industry. Their data will help consumer brands recognize opportunities to improve sustainability practices and decrease costs.

6. Viva Maris GmbH

Based in Schenefeld, Germany, Viva Maris GmbH is a green startup company that is committed to protecting the ocean through nutrition, education, and raising awareness about the human impact on the ocean. To do this, Viva Maris GmbH creates food products using an ultra-sustainable oceanic ingredient — algae.

Beyond their delicious algae products, the startup also prioritizes the protection of the ocean’s biodiversity, securing employment for former fishermen, and assisting with the preservation of natural marine algae.

7. Algenesis

It’s no secret that plastic is polluting our oceans, land, and air. Algenesis, an eco friendly startup founded in 2016 by Dr. Stephen Mayfield, is doing something about it. Using their patented Soleic™ technology, Algenesis produces fully biodegradable plastic made from algae. Not only is this a renewable product, but it is also a high-performance material allowing it to compete with plastics we currently use. Currently, the company produces footwear and hard material for surfboards; however, they plan to expand to include a variety of products to mitigate the use of wasteful plastics.

8. Bottle+

The sparkling water industry had a market size of $29.7 billion in 2020, and it’s estimated to grow at a compound annual growth rate of 12.6% from 2021 to 2028. With that type of growth, the number of wasted bottles and cans around the world that are produced to hold sparkling water will also increase. Bottle+ aims to counteract this problem by making a reusable water bottle that can turn flat water into sparkling water with the use of a small CO2 tank attached to the bottom of the bottle.

The bottle will ultimately reduce the production of single-use plastic waste that ends up in our landfills and in our oceans. The new bottle should produce the equivalent of 15 bottles of sparkling water and can be consumed while at work or in the comfort of your home. Consumers will be able to refill their CO2 tanks using a cylinder that can be found in many local grocery or home goods stores.

9. Smart Microfarms

Smart Microfarms doesn’t just grow highly sustainable, profitable, and nutritious algae known as Spirulina. This startup also produces scalable microfarms for homes, community gardens, and entrepreneurs to grow Spirulina as well. Their smart microfarms technology makes this type of farming accessible to even novice algae growers, decreasing the need for expert advice during production and helping to boost food security and entrepreneurship.

With an expert team including CEO Robert Henrikson, founder of Earthrise Farms — the world’s largest algae farm — and author of Earth Food Spirulina, you could say Smart Microfarms is a powerhouse in both the algae and sustainability spheres.

20. Olive

Online shopping is more prevalent than ever before, and unfortunately, that can mean an excess of waste and an increase in emissions. Olive has taken the initiative to create a cleaner method of online shopping by partnering with brands such as Goop, Anthropologie, and Adidas to provide a single delivery option that encompasses all brands featured rather than shipping items individually. Founder Nate Faust (who also co-founded Jet) launched the startup with a goal of minimizing the single-use packaging associated with online orders and provide an exceptional customer experience.

Fortunately, AMP Robotics, a startup founded by Matanya Horowitz in 2015, has a better idea. AMP Robotics, a recycling robot company, has developed AI technology that correctly identifies and sorts recyclables to ensure all materials that can be recycled are put to use. Not only will this decrease the amount of waste, but it will also streamline the recycling process which may increase the number of goods that are made of recycled materials.
