Why now
As major infrastructure builds, industrial facilities, and data centers enter aggressive rollout phases across the U.S., construction companies are under immense pressure to deliver more projects, faster.
Yet while AI has transformed industries such as finance, healthcare, and manufacturing, preconstruction, where every job is won or lost, still runs on manual takeoffs and spreadsheets. Attentive.ai is changing that.
From maintenance jobs to the construction core
Attentive.ai first built its AI engine to automate property measurements for landscaping and paving maintenance jobs using AI and aerial imagery.
Working closely with these companies revealed a broader truth: their construction divisions faced the same problem: takeoffs consuming hours of manual effort across trades.
That insight led to the creation of Beam AI, purpose-built for construction estimating.
Today, Beam AI automates takeoffs for mechanical, concrete, steel, civil, utilities, roofing, and more. Contractor & suppliers cite time savings approaching 90% and a meaningful increase in how many bids they can submit, often close to 2X in a quarter.
With over 1,100 customers, the platform is redefining what AI in preconstruction can achieve.
100% automated takeoffs: A category in the making
Construction is one of the largest industries in the world, yet the slowest to digitize.
“We’re in an era where AI is fundamentally reshaping every industry, and construction cannot be left behind,” said Shiva Dhawan, Co-Founder & CEO of Attentive.ai.
For decades, preconstruction has relied on manual takeoffs, spreadsheets, and siloed estimating processes that can’t keep pace with today’s scale or complexity.
“What sets this moment apart is the shift from tools to delivering outcome-as-a-service. With Beam AI’s human-in-the-loop model, estimators get 100% completed takeoffs and measurable productivity gains without adding headcount. We eliminate the repetitive, manual work so teams can focus on strategic bid prep that improves their win rate.”
The next wave of efficiency won’t come from marginal gains; it will come from AI-native workflows that redefine how estimators, project managers, and business developers operate.
AI for the preconstruction backbone
Preconstruction teams have always carried the weight of the bidding cycle, responsible for takeoffs, estimates, and bidding while racing against fast-moving bid submission windows.
Beam AI is turning those bottlenecks into data-driven, collaborative, and scalable workflows, enabling estimators and project teams to focus on strategy.
This momentum is being driven by the people who use Beam AI every day. The estimators & preconstruction managers are responsible for keeping projects moving. Their workflows are changing because the constraints that once slowed bidding down are, for the first time, starting to lift. The impact is showing up in the day-to-day pace of real projects.
For many teams, the shift exceeds just increased productivity; it’s confidence that the estimating process is finally modernizing in a way that respects trade knowledge rather than replacing it.
Looking ahead
This Series B fuels the next phase of expansion as AI becomes central to preconstruction - a decade of building smarter, faster, and together with AI at the center of every bid.
Attentive.ai hopes to expand into a full preconstruction software ecosystem, covering takeoffs, estimating, bid management, and collaboration all in one platform. The company is enhancing AI models for faster turnaround times across trades, investing in U.S.-based AI and engineering talent to accelerate product development, and strengthening marketing and customer success operations.
Attentive.ai is also scaling its enterprise footprint, partnering with large GCs, subcontractors, and suppliers in high-growth segments like mechanical, concrete, civil, utilities, and more. The long-term vision is to make AI the backbone of preconstruction, helping contractors bid smarter, faster, and with higher confidence, across every trade and every job.
