Key Takeaways
- Shackleton AI raised a $5M seed round led by Battery Ventures and left stealth on November 4, 2026.
- Its platform manages over $1B in project value across 15+ US states; valuation is undisclosed.
- The founders built the software inside Ernest, a contractor that reached $35M in revenue.
Lead
Shackleton AI came out of stealth on November 4, 2026, announcing a $5M seed round led by Battery Ventures. The New York company sells an "agentic operating system" for development and construction. It uses AI agents to take over the administrative work that consumes project managers. The platform launched in June 2026 and now manages more than $1B in project value across more than 15 states.
Brick & Mortar Ventures, Trust Ventures, Correlation Ventures, Motivate Partners, Thayer Investment Partners, Act One Ventures, Brainstorm Ventures, Silence VC and others also took part. The company did not disclose a valuation. It plans to use the money to widen the set of workflows its agents handle and to speed up sales.
What Does Shackleton AI Actually Do?
Shackleton sells a single system that covers the full project lifecycle, from site selection through project turnover. It combines development, preconstruction, project and field management, finance and communications, which contractors usually run in separate tools.
The agents handle specific chores. They draft requests for information (RFIs), flag overdue submittals and budget changes, and turn field notes into daily reports. Humans review and approve the work before it goes anywhere, so the product is built as an assistant to project teams, not a replacement for them.
Customers include midsize general contractors in multifamily, industrial and commercial construction. Multi-location restaurant brands also use it, among them Red Lobster, Dog Haus and Pepper Lunch. The company says customers have finished projects up to 35% faster and 18% under budget. Those figures are self-reported and the company has not published the baseline behind them.
Who Is Behind Shackleton AI?
Three co-founders run the company: Michael Ragheb, who is CEO, Hassan Yasin and Olexandr Kaltsev. They previously built Ernest, a tech-enabled commercial general contractor that grew to $35M in revenue across the Southeastern US. The agent platform began inside Ernest as an internal tool before the founders turned it into a standalone product.
That origin shapes the pitch. Construction software has a poor record of surviving contact with the field office, where superintendents and project managers drop tools that add work. A product tested on the founders' own jobs carries more weight than one designed from outside the industry.
Why Did Battery Ventures Back a Seed-Stage Construction Startup?
Battery led because it sees construction as a large, under-digitized sector where manual work is the norm. Michael Brown, a general partner at Battery Ventures, said: "Construction is one of the largest and least digitized sectors in the economy, and the teams running these projects are buried in manual work."
The round is modest by 2026 AI standards. At $5M, it funds a small team through a go-to-market push but not a long fight against well-capitalized incumbents. The investor list is also telling: a growth-oriented firm such as Battery leading a seed suggests it is betting on the founders' operating record as much as on the technology. The syndicate mixes real estate technology specialists with generalist seed funds, which fits a product that straddles property development and contracting.
How Crowded Is Construction AI?
Construction AI is busy, and Shackleton enters a market where established project management suites already hold the contractor relationship. Incumbents can bolt agents onto existing workflows, while startups must persuade firms to change systems. Shackleton's wedge is breadth: one system that replaces several point tools, plus agents that act on data across them.
That breadth is also the risk. A platform spanning development, preconstruction, finance and field management has to be good at all of them, or contractors will keep their existing tools and use Shackleton only for the agent layer. The $1B in managed project value shows early use, but project value is not revenue, and the company has disclosed no revenue figures, customer counts or headcount.
What Comes Next for Shackleton AI?
The near-term test is whether the agents can take on more complex work, such as change orders and financial reconciliation, without raising the review burden on human staff. Expanding beyond midsize general contractors and restaurant developers into larger firms would show whether the product scales past its founding niche. A follow-on round would likely depend on disclosed revenue and retention data that the company has not yet shared.
Outlook
Shackleton AI starts public life with a $5M seed, a Battery Ventures lead, a June 2026 product launch and more than $1B in managed project value. Its strongest asset is founders who ran a contractor and built the software for their own use. The open questions are valuation, revenue and whether a single platform can displace the tools contractors already use.
