CJ Venture Tech is a Spanish technology company. We build and publish our own software products and invest in technology projects and assets with a long-term view.
What we do
We combine building digital products with investing in technology. Each side feeds the other: what we learn by building guides where we invest.
We design, develop and publish applications, tools and services for web, desktop and mobile. Well-crafted, useful products that are maintained over time.
We invest capital in technology projects and assets with potential. We look for solid teams, products that make sense and long horizons.
We work with founders, developers and companies to launch joint products, license technology or open new markets.
Software
Tools and services designed and maintained by CJ Venture Tech. Every product starts from a real need and is built to last.

Send transactions, manage wallets (BIP39/BIP32) and query balances, fees and history on Bitcoin, Ethereum, Litecoin, Dogecoin, Bitcoin Cash, Avalanche and any EVM network. React hooks and conversion to 120+ fiat currencies included.
Automatic bookkeeping for freelancers and SMEs.
Upload invoices, bank statements from any bank and cash expenses just as you have them (PDFs, photos, zips): Aconta reads them, classifies them with smart tags and turns them into tidy transactions. Verifactu-compliant and free for up to 20 invoices a month.

Investments
Capital, considered decisions and a long-term horizon. We invest in technology and in assets we know well.
We like to back teams building useful products, with clear business models and the ambition to last. Minority stakes, direct dealings and no rush.
What we look at
Products with a clear, recurring and defensible model.
Infrastructure, automation and developer experience.
Concrete solutions to real problems, not promises.
Stakes, intellectual property, infrastructure and digital assets.
About
CJ Venture Tech was born from the conviction that good software and good investments share the same ingredients: patience, judgement and attention to detail.
We build things we would use ourselves, with the care they deserve.
We would rather grow slowly and well than fast and badly.
Capital and decisions free from outside pressure.
Clear communication with users, partners and collaborators.
