ConTech and PropTech start-ups are the most dynamic players in innovation in building, construction and architecture. And for this reason, they are obliged to face accelerated growth, incorporating external partners and investors with which to increase their turnover and expand their scope of action. Once again, REBUILD is dedicating an afternoon specifically to the entrepreneurial ecosystem of the sector. We will start the day with a round table, in which we will review cases and analyse the challenges and opportunities for startups on their way to scaleups. We will be joined by international experts, startup investors and founders of the best startups from previous editions of the REBUILD CONSTRUCTION TECHNOLOGY STARTUP FORUM. A whole afternoon dedicated to the present future of the sector from the hand of the most disruptive initiatives.
