There is a big gap between the innovations humanity has already come up with and what is available to patients for diagnostics and treatment. This gap is largely caused by a high degree of regulation which is needed to ensure patient safety. At Platomics, it is our mission to cut the gap between the technology humanity has at its disposal and what we can offer to patients - from currently up to 10 years down to 2 years and less.

Postservice.at gives founders, freelancers, online sellers and international companies a real, legally valid business address in the heart of Vienna, at Seitenstettengasse 5, 1010 Vienna, two minutes from Schwedenplatz. The why behind us is simple. Starting a company in Austria means putting an address into the commercial register, and for most founders the only free option is their private home address, which then stays public forever. We built the alternative we wished we had: a professional first district address that keeps your private one private. Unlike a PO box, our address is a genuine physical location with a company nameplate and a staffed reception. It is accepted by the Austrian commercial register (Firmenbuch), valid for the website Impressum under the E-Commerce Act, and recognised by the trade authority. That makes it usable for company registration, trade licensing, invoices and your website. Beyond the address, we handle your business mail. Letters are received in person on every business day, scanned GDPR compliant inside Austria, and delivered as PDF to an encrypted online mailbox, with options for forwarding, package acceptance and, on the Premium plan, RSb registered letter acceptance. Setup takes about two minutes online and the address is usually usable within one business day. Operated by 1010 Works GmbH and bootstrapped for over eight years, Postservice.at is trusted by more than 1,000 customers and rated 4.9 of 5. Plans start at 49 EUR per month, with no setup fee and monthly cancellation. We are a small, self funded team that values transparency, speed and real personal service in German and English, and we are building the simplest way to give any company a professional home in Vienna.

BOND is on a mission to open up Europe's 2.5 trillion euro public procurement market to the companies that are shut out of it today. Every year SMEs miss 40 to 60 percent of the tenders they could win, lose 8+ hours a week to manual search, and spend over 100,000 euros a year on it, simply because tenders are scattered across thousands of portals in more than 20 languages. We think that is both unfair and fixable. So we are building the AI platform for public tenders in Europe. Tender Match continuously monitors 2,000+ procurement portals across all 27 EU countries, translates every notice, and uses semantic AI to match it against a company's real profile. Our AI agents read 100+ page tender documents in seconds and run a gap analysis that shows exactly where a company is strong and where it falls short. The hard problems we solve sit at the intersection of large scale data, multilingual semantic matching and cost efficient AI. Our multi agent architecture lets us deliver enterprise grade analysis at a price SMEs can actually afford. We are backed by NVIDIA Inception, Microsoft for Startups and AWS. We are an early, fast moving team that ships quickly with modern AI and cares more about impact than titles. If you want to build something genuinely useful in a huge, overlooked market, with real ownership from day one, we would love to meet you.
