Osseus

Osseus is the secure research brain for R&D teams. Today, research knowledge is fragmented across specialist tools, decisions, conversations, and people's heads. Osseus crafts this into a permissioned memory that grows with every experiment, decision, failure, and lesson learned. Rather than only retrieving the current state of connected tools, Osseus preserves how work evolved: what was tried, what failed, why decisions were made, and who holds the relevant context. Each person gets a personal

Nessie

match 54

Knowledge work is being restructured by AI. Strategy happens in Claude. Research happens in ChatGPT. Building happens in Claude Code. The people defining the next decade of work are already thinking with AI every day. But none of that thinking compounds. Every session starts from zero. The reasoning behind decisions, the context behind strategies, the evolution of ideas across hundreds of conversations - all of it evaporates. Nessie is the infrastructure that makes it permanent. We auto-sync AI

Etacts

match 54

Etacts was born from the frustration of keeping in touch with our ever-growing list of friends (both business and personal), family, coworkers, and clients. It's impossible to remember to stay in touch with all the people that matter. Etacts helps you maintain your relationships by doing three things: 1) Showing you who you've lost touch with 2) Letting you set reminders to stay in touch with people 3) Helping you get back in touch meaningfully by giving you relevant context about your relations

Hyperspell

match 46

Hyperspell is your Company Brain. AI agents are brilliant and clueless. They ace any test and still have no idea how your company works. Hyperspell connects your tools and synthesizes documents and conversations into a live, permissioned context graph. Any agent can read from it and write back to it like a filesystem, with every fact traced to source.

Crouton

match 46

Crouton is the living map of your organization. It’s for founders and operators at growing companies who need to understand how people, teams, roles, and ownership actually fit together. Today they piece this together from org charts, Notion docs, spreadsheets, Slack, and memory and then redo it every time something changes.

Capacitive

match 43

We supercharge agents from Cursor to AgentKit with product and team-level context. Connect us once to where your internal data lives, then create secure data gateways with granular cross-platform permissions, comprehensive monitoring, and robust security filtering.

Dex

match 41

Dex is a personal CRM that reminds you to keep in touch with the people you would otherwise forget. Dex helps turn your acquaintances into your allies. Going beyond the superficiality of social networks requires commitment. If you remember to keep in touch thoughtfully, you can turn the interesting person you met at a networking event into a friend that has your back. I built Dex after failing to keep up with the tools I tried (Airtable, Notion, etc) for relationship management. Installing an ac
