Portfolio company Crewline raised a $7.1 million seed round led by Initialized Capital and Nebular to advance self-driving construction equipment. Its initial product, an autonomous vibratory roller guided via an iPad, is already operating on live job sites, signaling early commercial validation in a $10 trillion construction market.
The focus on automating heavy machinery aligns Entrepreneurs First with structural themes of labor shortages and flat productivity in construction. If Crewline scales its platform safely and efficiently, the company could strengthen EF’s positioning in industrial automation and support higher long-term portfolio valuations.
Bubble Robotics, another Entrepreneurs First portfolio company, secured a $5 million pre-seed round to build autonomous systems for continuous ocean operations. The company’s AI-driven robotic platforms are designed to function at sea without vessels or human crews, aiming to replace expensive, dangerous, and episodic offshore missions.
Bubble’s technology targets sectors such as offshore energy, subsea infrastructure, and marine monitoring, where persistent autonomous infrastructure could reduce costs and improve utilization. Entrepreneurs First backed Bubble “from day zero,” reinforcing its role as an origin-stage investor in frontier robotics and blue-economy themes.
Alongside portfolio funding news, Entrepreneurs First introduced “Build 2036,” a monthly, application-only founder forum in London. The gathering will convene small groups to debate a single long-term thesis about the future and identify high-conviction opportunities.
The Build 2036 format emphasizes structured critique over traditional networking, signaling an effort to attract analytically minded, thesis-driven founders. This initiative may enhance deal quality, deepen EF’s community, and strengthen its brand in a competitive early-stage venture landscape.
Collectively, the week’s activity highlights Entrepreneurs First’s commitment to autonomy across land and sea, while also investing in processes to surface ambitious new founders. These moves support the firm’s long-term strategy of building and backing deep-tech companies with potential for durable impact.
