AI-driven scheduling and contractor management visualized over an active construction site.
Denver, Colorado, August 20, 2025
Assignar, a cloud-based construction operations platform, secured a $20 million Series B to accelerate North American expansion, double headcount and develop AI/ML-driven features. The funding will support hiring across product, engineering, sales and customer success, boost research and development, and deliver new capabilities including a contractor hub and a schedule recommendation engine that uses data and machine learning. Targeting subcontractors and self-perform general contractors in heavy civil and infrastructure sectors, Assignar aims to improve resource-loaded scheduling, field data capture and real-time visibility across projects while scaling responsibly with the new capital.
Assignar, a cloud-based construction operations platform focused on heavy civil and infrastructure contractors, announced a $20 million Series B funding round on May 19, 2021. The raise was led by a real estate and proptech investor, with participation from prior backers and new investors. The company plans to use the capital to accelerate North American growth, expand its workforce, and add artificial intelligence and machine learning capabilities to its product.
The Series B was led by Fifth Wall, with a repeat investment from Tola Capital and a new investment from Ironspring Ventures. As part of the round, a partner from the lead investor joined Assignar’s board. The funding brings Assignar’s total capital raised since founding in 2014 to approximately $31 million.
Assignar says North America represents roughly 25 percent of its revenue and that the new funds will support faster expansion in that region. The company intends to double its headcount from about 65 employees and hire across all departments, while increasing investment in research and development. Planned product investments include a contractor hub and a schedule recommendation engine that leverages project data, AI and machine learning to improve planning and execution.
The platform helps subcontractors and self-perform general contractors schedule and track crews and equipment, capture field data and manage timesheets. It aims to streamline field-to-office operations, improve quality and safety oversight, measure productivity and give managers a real-time view of granular field activity. Assignar’s tools support resource-loaded scheduling, crew and equipment matching, and project-level progress monitoring.
Assignar serves hundreds of international customers across the United States, Australia, New Zealand and Canada. Its users work on public and private multibillion-dollar projects in infrastructure, road, rail, heavy civil and utilities. Customers range from specialist contractors operating a handful of crews to multinational firms working across major infrastructure programs.
The company was founded in 2014 and began in Australia before relocating its headquarters to Denver, Colorado in 2017. Assignar maintains offices in Denver and Sydney and positions itself as a platform aimed at the field-level subcontractor segment rather than software built solely for large commercial general contractors.
Assignar reports strong historical revenue growth, noting it has more than doubled revenue year over year since inception, with reported revenue growth of 75 percent in 2020. The company also notes that growth was paced to manage cash flow. A customer example cited in the company announcement shows measurable operational savings after adopting Assignar’s timesheet and reporting tools, along with faster access to consolidated project snapshots across many active sites.
The fundraise comes as infrastructure investment discussions in North America highlighted the need for better field-level visibility and productivity tools. The lead investor is a proptech-focused firm that manages capital commitments across real estate and related industries and has invested in a broad array of property and construction partners. The investor’s participation signals an interest in products that can connect project owners, general contractors and subcontractors through better operational data and execution tools.
Assignar will use the capital to speed development of a contractor hub to centralize workflows and launch a schedule recommendation engine that applies AI/ML to historical and real-time data. The roadmap also references creation of project optimization capabilities to improve crew and equipment assignment, reduce paperwork, and shorten planning cycles.
Executives framed the capital as a way to deepen market presence where public and private infrastructure spending is increasing, while addressing longstanding productivity gaps in construction. By focusing on subcontractors and field operations, Assignar aims to provide owners and large contractors with improved line-of-sight into field activity and productivity metrics that have traditionally been difficult to collect and act upon.
