Join Secures 6M in Series A Funding, Helping Solve Construction’s 9B Problem

OAKLAND, Calif.–()–Join, the leading decision-making platform for the built environment, announced today it has raised $16 million in Series A financing. The new funding round was led by SignalFire, along with participation from Building Ventures, Ironspring Ventures, MetaProp, and Standard Investments. This brings the company’s total amount raised to $30 million. The company will use the new funding to support rapidly increasing demand for its product.

Join, founded in 2017, is the first collaborative SaaS platform that facilitates decision-making and trust among all project stakeholders including contractors, owners, designers and architects.

“In construction today, various stakeholders are involved in taking a concept through design, planning, and procurement – meaning thousands of decisions are made typically using error-prone spreadsheets,” said Andrew Zukoski, Join co-founder and CEO. “Inefficient decision-making is costly, leading to rework, budget overruns and material waste. Join helps solve this problem by providing real-time visibility for all decision-making stakeholders to mitigate risk, ensure accountability and promote trust.”

​​Data silos are a prominent issue in the construction industry, due to large teams of stakeholders with data coming in from many different sources. Bad data in construction may have cost $1.84 trillion due to inaccurate, incomplete, inconsistent or untimely numbers and $89 billion of avoidable rework caused by poor decision making, according to a 2020 survey conducted by Autodesk and FMI Corp.

“These collaborative approaches require contractor input earlier in the process,” said Ilya Kirnos, Founding Partner and Chief Technology Officer of SignalFire. “Join is the only platform on the market designed to support collaborative decision-making, and its rapid adoption is a testament to its effectiveness.”

“Join has helped my current project simplify what used to be a time consuming, multi-step process,” said Melanie Moreschi, a Preconstruction Manager for DPR Construction. “Any time we’re working with an owner, particularly on a TVD job, there are numerous requests for the current job value during preconstruction. With Join, we have been providing that information instantaneously.”

The fast-growing client base of Join includes some of the largest firms in construction, such as Clark Construction, DPR Construction and McCarthy Building Companies. The construction management software has been used in a variety of projects – ranging from $2 million to $2 billion – for healthcare facilities, research centers, affordable housing, and entertainment and sports complexes.


Join simplifies decision-making in construction. The Join platform is the only software that addresses the multidisciplinary nature of AEC decision-making, enabling all stakeholders to gain real-time visibility into each decision and its impact. Industry leaders such as Clark Construction, DPR Construction, and McCarthy trust Join to make timely and smart decisions that drive projects forward. For more information, visit
