Abies Ventures, Inc. (Head Office: Tokyo, Japan; Managing Partner: Fuyuki Yamaguchi;
hereafter, “Abies Ventures”) is pleased to announce that Abies Ventures Fund I, L.P.
invested in Mighty Buildings, Inc. (hereafter “Mighty Buildings”), which produces
prefabricated housings by its own proprietary 3D printing technology based in San
Francisco, California, USA.

Abies Ventures is a venture capital firm that aims to discover startups possessing revolutionaryhigh-level scientific or engineering technology (deep tech) that contribute to the advancement ofhuman civilization and the realization of a sustainable society, and to develop them into global
companies.
Mighty Buildings aims to unlock productivity in construction by combining 3D printing andprefab, making construction more sustainable, efficient, and affordable. The company invented
a proprietary composite material that can be 3D printed and hardens almost immediately thanks
to a UV-curing process, while also maintaining cohesion between layers to create a monolithic
structure. Mighty Buildings can 3D print structures 2x as quickly with 95% less labor hours and10x less waste than conventional construction. The company can produce a large variety ofdesigns with a small workspace footprint because 80% of the work can be automated through3D printing and robotic finishing. The company has also developed new formulations thatincorporate recycled materials as well as end of life recyclability to close the loop on theproduction process, enabling virtually near zero waste.
The company offers two collections of 3D-printed homes, (1) Mighty Mods - where the houses
are fully produced off-site at its factory and transported to construction sites and (2) Mighty
houses - where the homes are assembled on-site with the panelized Mighty Kit Panel Systemmodules produced at its factory. Mighty Buildings is the first company to achieve certification
under the UL 3401 standard for evaluating 3D printed building structures and assemblies, andhas already sold and built its houses in California in the USA. The Company aims to expand its
business not only in the USA but also Asia market including Japan in the future. Ultimately, thecompany’s vision is to provide production-as-a-service, with builders and architects designing
their own structures and then using Mighty Factories to produce them.
