Contxto – Real estate continues to be riddled with problems for startups to solve (with a little help). Correspondingly, Colombian proptech Aptuno announced it raised US$680,000 in a pre-seed round through Magma Partners and angel investors. Aptuno’s platform was launched in April of this year and currently showcases 300 rental properties divided among Bogotá and Medellín. This is one of the pain points Aptuno wants to address via machine learning and its own stock of credit. La Haus is in the business of selling real estate while Aptuno is all about rental management.
