We build robotic arms. Custom-built robotic arms are already in use on the International Space Station and on planetary rovers. Our goal is to provide robotic arms that can be adapted for any space mission— from lunar surface missions to free-flying satellite missions. Robotic arms may be attached to lunar landers and rovers to enable a range of activities, including drilling, prospecting, instrument pointing, mobility, and cargo management. Made In Space Europe also provides robotic arms for orbital and free-flying missions, to support and enable activities such as satellite servicing and refueling, in-space manufacturing, debris capture, payload management, and more.

NativeMeet was created with a simple belief: the world understands places better through people, not polished tourism narratives. Every country has its own food, traditions, language, and everyday stories—but most global platforms fail to represent them authentically. NativeMeet exists to change that. We are building a global cultural community platform that connects people through real local experiences. Instead of curated travel highlights, NativeMeet empowers locals to share their culture as it is lived—through food, traditions, neighborhoods, and community stories. Our model is country-first: we work with one trusted community partner per country who understands local identity and helps grow authentic participation. NativeMeet blends community, content, and technology to create meaningful cultural connections. We collaborate with creators, students, and community builders to document local culture while maintaining trust, accuracy, and respect. Our platform is designed to scale globally while remaining deeply local. We are an early-stage, founder-led startup focused on sustainable, community-driven growth. While we are currently bootstrapped, our priority is building strong local networks, engaged communities, and a trusted global brand before scaling further. Our culture values authenticity, ownership, and inclusivity. We work remotely, respect local autonomy, and encourage our team to lead with pride in their roots. At NativeMeet, growth is measured not just by numbers, but by the depth of connection we create between cultures.

Briidge.one, builds applied AI into how professional firms actually operate, not as another bolt on subscription but as systems grounded in a firm's own record, running inside the workflows people already use and owned outright once we hand over the keys. Another AI subscription doesn't change a firm. AI changes a firm when it runs inside the actual work, grounded in the firm's own data. Most professional firms, MSPs, private equity, investment firms, law firms, real estate, other professional services carry client relationships and institutional knowledge scattered across 5-10, sometimes 15 disconnected tools. Hours leak, records fragment and decisions wait on someone's memory instead of on data that should already be there. How we work We're a company, not a subscription. Every engagement runs through five stages: 1.Diagnose- an audit of how the firm actually operates, run by the people who will build the solution 2.Design- a roadmap naming which workflows, in what order, and what each is worth 3.Build- AI grounded in the firm's record, shaped to the workflow rather than a template 4.Integrate- connected to the tools the firm already runs, so one record moves instead of being retyped between systems 5.Improve- iteration after handover, sized to what's at stake. We build on the platforms professional firms already rely on Atera, ConnectWise, NinjaOne, HaloPSA, Datto, Autotask, DealCloud, Affinity, Datasite, Intralinks, Carta, PitchBook, Clio, iManage, NetDocuments, DocuSign, Yardi and MRI rather than asking firms to rip out what already works. What we put our name on: No outside logos to borrow. Clients own the code, the schema and the data outright with documentation complete enough for another team to take over. No lock in, nothing trained on a client's record and an exit built into every engagement from day one. We're building the team that will define what applied AI looks like for the firms that run the professional world.
