Alga was born from a simple belief that climate action should not be a privilege. Coming from technology and climate backgrounds, our founders experienced firsthand how complex and inaccessible sustainability can be even for companies willing to do the right thing. We were driven by a shared conviction that we will only solve the climate emergency if access to innovative solutions is democratized and climate compliance becomes a default, not a luxury. Alga exists to make climate action real, practical and within reach for every business.
