What's the endgame? The platform pulls workflows — from site selection and bidding through project turnover — into one system. Its AI agents draft RFIs, chase overdue submittals, flag budget variances, and turn field notes into daily reports, work that today spreads across seven to 10 separate tools and costs teams 10 to 15 hours a week.
The traction: Launched in June 2026, Shackleton now manages more than $1 billion in project value across over 15 states, serving midsize general contractors and multi-location brands including Red LobsterDealroom has a profile for this one. Try Dealroom →, Dog HausDealroom has a profile for this one. Try Dealroom →, and Pepper LunchDealroom has a profile for this one. Try Dealroom →. The company says multi-location customers have finished buildouts up to 35% ahead of schedule and as much as 18% under budget.
Why now? Co-founders Michael Ragheb, Hassan Yasin, and Olexandr Kaltsev built the product after scaling Ernest, a commercial general contractor, to $35 million in revenue while battling fragmented software. "I was spending more time moving data between systems than running my jobs at Ernest," Ragheb said.
Investor view: "Construction is one of the largest and least digitized sectors in the economy," said Michael Brown, general partner at Battery Ventures. "We believe their agentic approach is how construction projects will be managed going forward."
The signal: At $5 million, the round lands near the 91st percentile for US seed deals in real estate, a sign of investor appetite for AI tools targeting construction's long-standing digitisation gap — intensified by tariffs, higher interest rates, and owners demanding faster rollouts.
