Investor Profile: Apex Ventures — Thesis, Cheque Size & How to Apply

For deep-tech founders in Europe, APEX Ventures — styled Apex Ventures — is a specialist worth a close look. The Vienna-based firm says it backs the most ambitious deep-tech founders as they turn scientific insight and engineering excellence into category-defining companies, with a focus on early-stage companies where defensible intellectual property, technical depth and market timing come together.

APEX Ventures was founded in 2016 and is based in Vienna, according to investment directories. Its team, in its own words, combines scientists, engineers, operators and investors, with technical expertise, investment experience, operational know-how and access to European deep-tech ecosystems.

Thesis and sectors

The firm focuses on technology domains with the potential to reshape large global markets, and it names six of them: Artificial Intelligence, Autonomous Systems & Robotics, Energy Transition, Next-Gen Computing, Medical Technologies and Space. Its strategy language is consistent — massive markets, exceptional problem solvers — and it looks for founders best positioned to lead in those markets, not for incremental products with a thin technical moat.

Stage discipline is equally clear. APEX Ventures invests at early stage, from Seed to Series A, in Europe.

Fund size, cheque size and portfolio

APEX Ventures does not publicly disclose a single headline fund size on its official site, so this profile records its fund size as not publicly disclosed rather than borrowing a figure from a different firm with a similar name. What it does state is its average initial ticket: €0.5m – €2.5m. That range tells a seed or Series A founder immediately whether the firm can lead or co-lead a round of the size being raised.

Its portfolio, showcased on its own site, includes ATMOS Space Cargo, HyperHeat, OroraTech, planqc and Quibim. Recent portfolio news underlines the range: Spleenlab, which builds artificial intelligence that helps robots perceive the world, was acquired by Quantum Systems, and Mobius Labs was acquired by Dropbox, while UniSieve has put a membrane-powered carbon-capture unit into operation and planqc has argued the case for industrial-scale quantum investment to European leaders. Founders quoted on the firm’s site praise the same things: fast strategic understanding, hands-on help to focus and execute, and experience scaling deep-tech companies.

Partners, programmes and support

The firm’s published team includes Tim Hos, Andreas Riegler, Wolfgang Neubert, Stefan Haubner, Golnaz Borghei and Marcell Farkas, among others. APEX Ventures does not advertise a public accelerator programme or a credits and perks scheme; its support model is direct partnership and access to its European deep-tech network, including technical, commercial and hiring help as companies move from breakthrough to global business.

How to apply for funding

APEX Ventures does not run a public application portal. Its official site offers a “Get in touch” contact route, and that is the correct first step, ideally reinforced by a warm introduction from a portfolio founder, a university technology-transfer office or a European deep-tech investor who knows the team. A strong approach leads with the scientific insight, the protectable technology, the market it can reshape and the evidence so far, and it states the round size plainly so the firm can judge fit against its €0.5m – €2.5m initial ticket.
