[Newsletter #3] Verustruct is Building Momentum – July 2025 Update

Verustruct is developing a suite of novel construction robotics to deliver affordable, sustainable, safe, and beautiful housing, starting with our patent-pending translational slip form (TSF) device. 

Friends of Verustruct, The last few months have been full of exciting progress for the team - big awards, important technical milestones, and fundraising traction. We've also learned some important lessons as we delved into material testing and customer discovery. Below, you'll find company highlights, a candid look at some lessons learned, and what we're building towards next. 

Key Highlights

• USPTO nonprovisional patent filed related to our TSF technology, with 2x continuation patents in the works. 

• Small-scale prototype (v2) completed and successfully demonstrated gantry-less wall scaling operations.

• Cementitious material testing in progress, with 1,000 lbs of free material secured from O&G Industries and initial testing showing promising printing material attributes. 

• 3x Letters of Intent secured from real estate developers and a general contractor excited about working with us once our full-scale tech is ready.

• We won 2nd place and Audience Choice Award for the Planetary Solutions Prize at Startup Yale.

• We also won 2nd place and a Golden Ticket at ClimateHaven (1 year of free rent) for the Climate track at the Yale Innovation Summit. 

• Acceptance into the Keel NYC acclerator, with $150k in funding secured on our round terms. 

Blueprints, Bots, and Big Wins!

We've Kicked Off Full-scale TSF Device Development

Our successful small-scale prototype testing and promising material R&D results have unlocked full-scale TSF device development, and the team is hitting the ground running. We've worked through a full-fledged design criteria review (DCR) for the full-scale printing system, defining critical requirements and our design envelope so we can deliver a fully functional prototype that creates load-bearing, code compliant, beautiful walls. Design work is in full-swing for our dynamic formwork subsystem, with initial manufacturing and testing on our first iteration of this subsystem planned for the end of July.

What We've Learned - Customer Discovery

On the customer discovery side, we've had a ton of insightful conversations and gotten a better sense of what real estate developers are looking for. We've also learned a few things along the way:

• Cost, compliance, and trust matter the most.

• It's becoming more difficult for developers to build projects with rising material costs, labor shortages, and high contractor quotes.

• Developers are becoming more receptive to newer, cost-effective technologies, and are more open to talk through their problems than we predicted..

• Just because a developer says they're willing to sign an LOI, it doesn't mean they will. Classic sales rules still apply. 

We're using these insights to shape our final TSF device, with our design envelope reflecting cost-effectiveness, features to ensure code-compliance, and extreme reliability to become a trusted solution. 

What We've Learned - Materials R&D

We've also been working through material testing, and we've learned some lessons the hard way:

• Concrete mixes are especially sensitive to their water-to-cement (w/c) ratios.

• Ambient conditions matter more than one might think.

• It's possible to burn out a mixing drill with the right (wrong) drill. 

These lessons have shaped recent testing, with samples created that have desirable cure times, cohesion properties, and compression strength development.

What's Next

We are excited to keep making progress on the technology and material R&D fronts, with manufacturing and testing of preliminary full-scale TSF subsystems taking place over the next few weeks, along with concrete formwork testing. Some of our bigger milestones for the next 4 weeks include:

• Design, analysis, manufacturing, and testing of the dynamic formwork subsystem for the TSF device. This will be our first iteration in a series of rapid iterations! 

• Load-bearing wall first layer creation and testing, with various cross-sections and material mixes designed and tested. 

• Continued customer discovery conversations and software development, working through front-end UI/UX for our house design printing software. 

We're also building significant momentum on our fundraising round - reach out to me directly (you can just reply to this email) if you want specific updates on our fundraising progress.

Key Asks

We're looking to connect with civil engineering/residential construction experts that have exposure to the regulatory requirements for single-family home construction in the U.S.

Any introductions would be extremely valuable, thank you! 

Thank you for being part of our journey.We’re gaining momentum and excited to keep making progress. Stay tuned for out next set of updates in August.

With gratitude, Nick Callegari Founder & CEO, Verustruct
