Investors - CalcTree

CalcTree is one of seven contech startups selected from over 185 applicants to participate in Suffolk Technologies' contest-focused 

BOOST is an intense six-week startup accelerator that connects technology startups in the built world with academics. Program partners include Autodesk, Procore, Moog Construction, and more. 

By leveraging Suffolk’s tremendous resources and national platform and partnering with innovative startups through the BOOST program, we are identifying the forward-thinking leaders, organizations, and solutions that will unlock our industry’s potential and eventually help us redefine the built world.

- Parker Mundt, Vice President of Platform for Suffolk Technologies

Suffolk Technologies is the venture investment affiliate of Suffolk Construction, ranked #23 on the Engineering News-Record list of “Top 400 Contractors", with $4.5 billion in annual revenue and 2,400 employees.

The construction industry today faces unique challenges in response to current economic conditions. Among increasing project complexities and a growing urgency for sustainable development, owners and contractors are confronting labor shortages, materials cost escalation, and supply chain disruptions. These significant challenges directly impact project outcomes. A recent survey commissioned by Procore Technologies, Inc. (NYSE:PCOR), a leading global provider of construction management software, found 75% of construction projects are over budget, and 77% are behind schedule.

Recognizing the immediate need to leverage digital solutions to address labor, supply chain, design, sustainability, and automation goals, three years ago Suffolk Technologies, the venture investment affiliate of Suffolk, created its BOOST program.”

If you’re an Investment Analyst, Associate, Principal, or Partner, you’ll want to know who the existing backers are of a startup. It’s part of building conviction. We’ve written this article detailing the investors who’ve come on board. 

At the end of this article, we outline precisely how you can reach us and the expected next steps to quickly determine whether CalcTree is a potential fit for your investment thesis.

We avoid cold starts where we can, which means attending to something before it hits the ‘Important / Urgent’ quadrant. This is part of the culture we’re creating at CalcTree, which you can read more about 

. Our preference is to build investor relationships well ahead of time where trust grows by following our updates and milestones. 

Below is a spotlight on some of the investors we’re proud to have onboard. In addition to those listed, we’re equally pleased to have a network of investors with the right mix of expertise covering the various dimensions of building a successful startup. We’ve enjoyed going on the journey together, learning from them, and getting support when required. 

Right from the start, we felt an investment from Foundamental made sense due to their strong understanding of PLG startups in the built environment. In 

, we explain why we believe the contech space needs more product-led growth startups.

Foundamental's impressive portfolio includes startups like Speckle, Snaptrude, Rayon, Alice, Enter, Infra.Market and many more. Many of them have gone on to raise funds from top tier global VCs (Accel, a16z, Insight, etc.) in following rounds, so we’re excited to be in such great company!

“CalcTree's platform revolutionizes the workflows of engineering calculations, enabling real-time collaboration between cross-functional teams and democratizing knowledge access for AEC professionals across the globe. We are grateful to CalcTree and the team for choosing us as their partner on their journey.”
