Developing an Emergency Services Platform and Contributing to $16M Funding Round of RapidSOS


RapidSOS is a US-based privately funded company in the emergency services platform business. They have partnered with Internet of Things companies and the public safety community to create the RapidSOS Emergency API — a product that links any connected device to 9-1-1 and first responders, making it possible to get unprecedented life-saving data to public safety in an emergency.

About the project

When we were first approached by RapidSOS, they were developing their Emergency API. At that time, they already had an existing platform that was receiving signals from the outside and processing them, but the steps of this process were customized separately for each client.

Our tasks

Building a more intuitive model to help serve more customers faster

RapidSOS looked to build an interactive module of their product interface that would help users design workflows on their own in a graphical form.

Providing the client with a PoC and building front-end

Before developing a fully functional front-end part of the product, we were tasked to build a Proof-of-Concept utilizing Rappid (JointJS+).



1. Serving more patients quickly

In order to be able to serve more patients quickly, the client needed a new, more intuitive module for the interface where the users could design workflows on their own, interactively, and graphically.

2. Finding a cross-functional team proficient at Rappid (JointJS+) framework

While trying to develop such a solution, the client came across the Rappid framework (from 2022 known as JointJS+), but having no in-house experience with said technology, they looked for a tech partner who would be proficient at it.

Neoteric has built a strong technical foundation, and the quality of their deliverables continues to impress. They provide us with a level of innovation that most outsourcing environments don’t. They thrive in environments that require them to make more holistic designs, or even in proposing new user interactions that we didn’t specify.They provide very good results. I’m also surprised at how independent they are.

1. Building a proof of concept

In the first three weeks, we utilized Rappid (JointJS+) to build a proof of concept based on the delivered requirements. After getting the green light to move on to the second phase of the project, we began building the front-end portion of a fully-functional product.

2. Developing a front-end side of the product

During that phase, we faced some challenges, the biggest of them being the restrictions of Rappid (JointJS+) itself. In order to fulfill the requirements of RapidSOS, we needed to extend the capabilities of the framework and develop one of its functionalities.

The solution worked and was eventually implemented by the creators of Rappid (JointJS+) and included in its next version. The module we created solved the problem presented to us by RapidSOS and there was no further need to customize the process for each user.

Technology we used

Project Results

Teaming up with Uber

In April 2018, RapidSOS teamed up with Uber to pilot an in-app 911 feature with emergency authorities in multiple cities. The feature helps participating 911 centers better locate mobile 911 callers and provides valuable safety and security for Uber users.

Getting $16M founding from Microsoft

Also in April, Microsoft Ventures joined RapidSOS in a $16M funding round to accelerate the deployment of the RapidSOS Next-Generation-911 Clearinghouse, a free software upgrade for 911 centers to receive data from IoT devices utilizing the Emergency API.


The solution we built utilizing Rappid (JointJS+) was successfully implemented by the client. As a result, with the ready product in place the client partnered with Uber aiming to boost security of Uber users. Later, RapidSOS received funding of $16M from Microsoft Ventures.
