From energy startups to robotics and artificial intelligence companies, the Puget Sound is home to a diverse array of tech businesses, many of which raised capital last month. In fact, the companies that raised April’s five largest funding rounds pulled in a collective $117 million, slightly up from the largest rounds raised by Seattle tech companies in March.

Backed by fresh capital, these local tech businesses have big plans. Read on to see who topped the list this month and what each company has in the works.

Fixie is currently hiring for several engineering positions.

Lexion is an operations workflow and contract management software. The company was founded in 2019 to help the legal industry, but it has since expanded into healthcare, manufacturing, consumer goods, gaming and more. Lexion secured a $20 million Series B round led by Point72 Ventures in April, bringing its total capital raised to more than $35 million to date. This includes an $11 million Series A in 2021 and $4.2 million seed round in 2019.

Carbon Robotics creates cost-effective and efficient tools for farmers, including a laser-weeding robot powered by AI.

Developing energy power packs and micro-fusion reactors, Avalanche Energy closed a $40 million Series A round from Toyota Ventures, Founders Fund and others.
