How Attentive AI is Empowering the Backbone of the Preconstruction Industry with AI

Attentive AI, the company behind Beam AI, led by Shiva Dhawan, Rishabjit Singh, Shikhar Tripathi, and others, has announced a $30.5 million Series B funding round led by Insight Partners, with participation from Vertex Ventures, Tenacity Ventures, and InfoEdge Venture Fund.

As large-scale infrastructure, industrial, and data center projects surge across the U.S., construction firms face mounting pressure to build faster and more efficiently. While AI has revolutionized sectors like finance and manufacturing, preconstruction, where projects are won or lost, remains largely manual. Attentive.ai is changing that.

Attentive.ai started by automating property measurements for landscaping and paving using AI. Seeing the same manual inefficiencies in construction led to Beam AI, built to automate takeoffs across trades like concrete, mechanical, and roofing. Now used by over 1,100 customers, Beam AI helps contractors save up to 90% of their time and nearly double their bids, redefining AI in preconstruction.

Construction, one of the world’s largest yet least digitized industries, is entering a new AI-driven era. For decades, preconstruction has depended on manual takeoffs and spreadsheets that can’t keep pace with modern demands. Beam AI changes that through a human-in-the-loop model that delivers fully completed takeoffs and measurable productivity gains without increasing headcount, allowing teams to focus on strategic bid preparation. The next leap in efficiency will come from AI-native workflows that transform how estimators and project teams operate.

Preconstruction teams have long shouldered the pressure of takeoffs, estimates, and bids within tight deadlines. Beam AI transforms those bottlenecks into data-driven, collaborative, and scalable workflows, freeing estimators and project teams to focus on strategy and winning more bids.

This momentum is fueled by the estimators and preconstruction managers using Beam AI daily. As long-standing bottlenecks in bidding begin to lift, their workflows are transforming, driving faster execution and real impact on active projects.

This Series B fuels Attentive.ai’s next phase of growth as AI becomes central to preconstruction, powering a new era of faster, smarter, and more collaborative bidding.

The company is expanding into a full preconstruction ecosystem spanning takeoffs, estimating, bid management, and collaboration. It’s enhancing AI models for quicker turnaround, growing its U.S. engineering team, and deepening partnerships with major GCs and subcontractors across key trades to make AI the backbone of every bid.
