Here are the five Startup Battlefield finalists at Disrupt Berlin

Fourteen startups presented on-stage today at Disrupt Berlin, giving live demos and rapid-fire presentations on their origin stories and business models, then answering questions from our expert judges.

Now, with the help of those judges, we’ve narrowed the group down to five startups working on everything from productivity to air pollution.

These finalists will be presenting again tomorrow (at 2pm Berlin time, viewable on the TechCrunch website or in-person at Disrupt) in front of a new set of judges. The winner will receive $50,000 and custody of the storied Disrupt Cup.

Here are the finalists:

Gmelius

Gmelius is building a workspace platform that lives inside Gmail, allowing teams to get more bespoke tools without adding yet another piece of software to their repertoire. It slots into the Gmail workspace, adding a host of features like shared inboxes, a help desk, an account-management solution and automation tools.

Hawa Dawa

Hawa Dawa combines data sources like satellites and dedicated air monitoring stations to build a granular heat map of air pollutants, selling this map to cities and companies as a subscription API. While the company notes it’s hardware agnostic, it does build its own IoT sensors for companies and cities that might not have existing air quality sensors in place.

Inovat

Inovat makes it much easier for travelers to get reimbursed for the value-added tax, through an app that employs optical character recognition and machine learning to interpret receipts, determine how much VAT you should be owed for your purchase, and prepare the requisite forms for submission online or to a customs officer.

Scaled Robotics

Scaled Robotics has designed a robot that can produce 3D progress maps of construction sites in minutes, precise enough to detect that a beam is just a centimeter or two off. Supervisors can then use the software to check things like which pieces are in place on which floor, whether they have been placed within the required tolerances, or if there are safety issues like too much detritus on the ground in work areas.

Stable
