Gridless, a bitcoin mining company, has raised $2 million in a seed funding round led by Twitter co-founder Jack Dorsey’s payment company Block (SQ) and venture firm Stillmark. Gridless helps generate new sources of energy in East African rural communities. The investment will support the company’s expansion of bitcoin mines across African markets. In its first year, Gridless has contracted five project pilots in rural Kenya with African hydroelectric energy company HydroBox.
