In today’s world, Virtual Reality has great positive impact all over the industries, especially for the architects and designers in the construction field. Virtual Reality enables the formation of a digital twin and decreases the burden it has in visualizing the design and product.


Founded in the year 2015 by Gautam Tewari and Tithi Tewari, Trezi is a completely diversified virtual reality platform that completely transforms the design experience for the AEC industry by uniting together all the stakeholders involved in the design project in order to team up at full scale. This platform offers a real-time, diversified, and interactive design experience that verbalizes design plan to match client expectations,and provides significant business impact and further enhance and improve profitability.

Trezi help architects and designers in order to get intuitive designing and fast decision-making, that results in decreased errors and omissions, time and cost benefit and scale up clients satisfaction. In order to build Product Manufacturer and Suppliers, Trezi act as a platform for digital product mock-ups and staging. Trezi improves product experience, understanding, and market reach, generates time cost savings, as well as build a unified customer engagement. 

Trezi was launched with a aim to become the leading immersive and diversified design collaboration platform for the creating industry that unite together all stakeholders in the design project, including architect/designer to engineering services to owner/tenant. The aim is to collaborate on the 3D design in an interactive and immersive environment and make better decisions.


Tithi Tewari along with her husband, Gautam Tewari’s startup SmartVizX came up with Trezi, a completely immersive virtual reality(VR) product that aims in helping all stakeholders in the building construction industry collaborate and communicate effectively. Both of them has a degree in Construction Management from the University of New South Wales, Australia has more the 20 years of area of expertise in the design and architecture industry.

Serving in architecture and design industry for more than 20 years, Tithi noticed various issues and situations during communicating design plans to clients via traditional tools and mediums which helped a little in order to aid their overall understanding. Regardless of the extensive use of 3D renders and walk through, she witnessed that clients had difficulty in visualizing the end-product.

This resulted in differences in expectations and the end-product or the final outcome, miscommunication, and time and cost overruns. These challenges made Tithi and Gautam to come up with a solution to benefit with seamless design collaboration, virtual co-location of teams, and remote working without a hitch. This led them to launch the startup with the idea of virtual reality at its core. 

“Trezi is a breakthrough SaaS product transforming design communication in the building construction industry. It allows users to step into the virtual world with co-designers and clients to interact with their design, and each other, in real-time, within immersive environments and over desktop systems alike,” explains Tithi.


Trezi is even used by India’s topmost architects, infrastructure developers, co-working companies, large enterprises, developers, and manufacturing firms. Tithi says the product is used by more than 50 percent of India’s top 50 architecture firms. When compared to conventional methods, the VR products helps architects, designers, consultants, as well as building product manufacturer to associate seamlessly and its time and cost-efficient.

“We are not the typical fresh college grad kind of a startup. We have been in the industry for long, and have extensive hands-on experience. Early traction came from my professional network who eventually became our customers as well. These networks definitely helped us kickstart the sales, followed by word-of-mouth publicity. Also, because of our experience and the understanding of the field we could talk incisively about the pain points during our outreach,” Tithi says. 

In just five years of its inception, the startup has an total revenue of around $4.5million. It enables users to explore, review, and modify their designs at full scale and colour. Due to the COVID-19 pandemic and the continuous lockdown, the building construction industry has been hit badly. Migrant labourers are losing jobs and finding it difficult to stay afloat and corporations are continuing to work remotely during these times. With stay at home orders and work-from-home becoming a new normal, Trezi is helping the industry continue with their work. 

The startup is working to enable a smooth transformation from traditional office ecosystems to agile virtual workplaces for all their customers. As Trezi is a first ever VR product, it has allowed the use of the software over standard desktop systems without a hitch – which implies that the unavailability of a VR headset or a powerful PC need not hold people back from using Trezi. “As an industry, we have been extremely averse to new tech. This pandemic may just wake us all up to that reality. A new way of working, collaborating, and information sharing is bound to emerge,” says Tithi.


In the year 2016, Trezi raised $500,000 funding in angel round of funding that was led by IAN and Stanford Angels and Entrepreneurs. After this in July 2018, it raise $1.5 million funds in Pre-Series A round of funding led by YourNest VC and IAN Fund. Trezi recently raised around $1 million that was led by existing investors and Rockstud Capital Investment Fund.
