Thor’s Hall is building a performance-based network for creators, publishers, marketers and online communities.

Our model is simple: if a partnership generates revenue, everyone involved shares in the results. We currently focus on online gaming and iGaming, with the goal of building a wider network of creators, publishers and growth partners across multiple markets. We are still early, which means the people joining now have the opportunity to help shape how Thor’s Hall grows, test new acquisition strategies and potentially develop long-term partnerships as the network expands.

Pathr is building the connected intelligence layer for boating. Our marine navigation app is live on iOS and Android, helping boaters plan safer routes, navigate waterways, monitor their vessels, and make better decisions on the water. We're also developing HelmLink, our hardware platform that connects directly to a boat's NMEA 2000 network and brings real-time vessel data into Pathr. Together, the app and HelmLink create a growing marine data network. We're building toward tools for recreational boaters, commercial operators, fleets, marinas, and other businesses that need better visibility into what's happening on the water. We're a small, early-stage team solving difficult problems across navigation, geospatial data, routing, hardware, mobile software, and marine intelligence. That means people joining Pathr early have the opportunity to own meaningful parts of the product and help shape the company from the ground up. If you're excited by boats, maps, connected hardware, real-world data, or building ambitious products at the earliest stage, we'd love to hear from you.

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.
