sproof sign: Digital signature tool launched with major customer on board

With sproof sign, the Salzburg-based start-up sproof has launched a digital signature tool. The experts for document certification are hitting a nerve with it. Major customers contacted them even before the official launch.

Clemens Brunner, Fabian Knirsch and Erich Höpoldseder from sproof recognized the need for signing documents and contracts from any location already before Corona. “We have noticed that many are working with the semi-digital method: Print out, sign, scan, e-mail, then send the original by mail to ensure legal compliance, and if there are several signatories, the whole procedure is done in several rounds. With sproof sign, we provide companies with a tool that digitizes this process quickly and easily,” says Erich Höpoldseder.

This company already relies on sproof sign

For ADVOKAT, Austria’s leading provider of software for lawyers, the tool is an ideal addition to its range of services. The pioneer in terms of law firm automation supplies more than 2,200 law firms and companies with its software. ADVOKAT Managing Director Dr. Manfred Wurz: “sproof sign was integrated with our system in a simple way. In the future our customers will be able to collect digital signatures in three simple steps. A practical feature that is in great demand in times of Corona”.

It was important to the software market leader that the electronic signatures have legal validity. “This is given by the mobile phone signature. When it comes to data security, we also use state-of-the-art encryption and servers in the EU,” explains Fabian Knirsch, CTO of sproof.

Corona as a customer magnet

The privacy and security experts at sproof – Clemens Brunner and Fabian Knirsch, both researchers at the Center for Secure Energy Informatics at the Salzburg University of Applied Sciences – have developed the new tool in the last months. Given the current crisis, the fact that their idea generated such great interest came as a surprise for the three business partners. “We had actually prepared ourselves for the fact that customer acquisition after the lockdown would be slower, but the opposite is true. Companies have an urgent need for digital signatures and more resources to deal with our product,” says Clemens Brunner.

About sproof sign

With sproof sign, contracts, circulars, or agreements can be signed in all the usual variations, from a manual signature to a digital or legally required official signature. sproof sign automatically takes care of inviting contacts, collecting signatures, and sending automatic reminder emails. At any time, the issuer can retrieve the current status of the signatures already made for a document and save the signed document on his or her PC or server system. For administrations and companies that want to integrate sproof sign into their existing applications via API, sproof offers a cost-effective premium API.

Demo Day 2020: This was the pitch

demo day video conference pitch screenshot

Yesterday was the day: we got to present sproof at the Startup Salzburg Demo Day 2020 in front of a top-class expert jury and a broad audience including investors, founders and other entrepreneurs.

When we joined the Startup Salzburg Factory last year, we knew this was the beginning of something great. After nine months of fine-tuning our ideas, working on our business plan, talking to mentors and networking with relevant stakeholders, we were ready for the highlight of this journey.

Positive feedback from the jury

For the first time, the stage of the Demo Day was online and the event virtual. But thanks to the great organization by Startup Salzburg and derBrutkasten, everything turned out just fine. Almost 200 participants joined in when Fabian Knirsch, CTO of sproof GmbH presented our three-minute-pitch to the audience.

In the prominent jury sat ICT top-manager Eva Wimmers, Clever Clover president Heinrich Prokop, business angel Olav Carlsen, founder Marius Donhauser and investor Franz Fuchsberger. We were more than happy to hear their positive feedback!

Our Startup Salzburg Factory journey

Over the last months, the Startup Salzburg team accompanied us in bringing our business idea to the market. In addition to individual coaching, we were professionally accompanied by our mentor Mag. Gabi Tischler from the Salzburg Chamber of Commerce and got the opportunity to network at exclusive events. We got a lot of feedback and took lots of inspiration from the factory and we are looking forward to the time after the factory.
