Solari gives non-technical team members access to agents that work right out of the box.
Sona8 is a voice agent that talks to every employee in a company about how their work gets done. Each employee gets a link and talks to the agent for about 20 minutes. The agent asks follow-up questions, for example why a step is still done by hand or who else is involved. From the conversations we build process maps and a list of the problems people described, sorted by site and team. That is the start. We then stay on through the implementation. After each initiative is rolled out, the agent goes back to the employees involved and asks whether it was implemented and what changed in their daily work. The transformation team sees this after every rollout step. The result is a project management office that has talked to every employee. That context did not exist before, because nobody had the time to collect it. Consulting firms use it to gather ideas at the start of an engagement instead. Transformation and corporate development teams use it to guide the execution of strategic transformation.
We’d like to automate monitoring. To advance that mission, we’re building Sonarly. Software has two phases: build time and run time. Coding agents are getting great at build time, but production is still a mess of charts, logs, and noisy alerts. Sonarly triages production alerts, deduping - prioritizing, and attaching the missing context - so teams can trust what pages them and fix the right issue fast. As you deploy new code, Sonarly keeps alerts and investigations up to date automatically.
With Soon you can invest without the stress of speculating. Our fully automated sweep account attaches to your bank and uses routine spending activity to signal market trades.

Industry leaders like Abnormal AI and eToro use Spinach to capture and transform raw conversations into structured knowledge that powers people, agents, and LLMs across the enterprise, driving productivity for workers and strategic insight for leaders.
Spine AI is a visual workspace where a single prompt spins up a swarm of AI agents that plan, delegate, and execute complex tasks together — with humans fully in the loop. Instead of chatting back and forth with one model, Spine breaks work into visible steps on a shared canvas. Agents collaborate in parallel, ask clarifying questions, use connected tools, and show their reasoning and intermediate outputs as they work. Every agent’s work stays inspectable, auditable, and editable — reducing hallucinations and giving you real control over the outcome. Spine connects to leading AI models and your existing tools, but the real power comes from orchestration: you act as the team lead, Spine runs the swarm. Chat is great for answers. Spine is built for execution.

With AI increasingly automating away code generation, software engineers will spend more time reading, judging, and architecting code rather than writing it. Storia is building an open-source copilot that knows a company's codebase and its context. We are starting with Sage, a Perplexity-like agent for helping developers understand, judge, and generate software. Given an existing codebase, developers can ask Sage questions such as: 1) Given my project’s SLA and latency constraints, what is the appropriate underlying vector database to use? How would I incorporate it into my existing codebase? 2) Why should I pick Redis over Milvus as my underlying vector store? 3) Does this codebase in our organization still work and what steps are required for a complex integration with another library? Sage’s answers are directly supported by documentation and external references like GitHub, Stack Overflow, technical design documents, and project management software, preventing hallucinations. Today, Sage has up-to-date knowledge about open-source repositories (indexed daily). Tomorrow it will have a deep understanding of every line of code on the Internet. For teams, Sage will know about your private codebase too. No group has yet solved how to build an AI system that comprehends a codebase and its context and can empower every developer to architect better code, faster. This requires new research advances because vanilla RAG and out-of-the-box LLMs aren’t going to cut it. We have 20+ years of software engineering and AI research experience. Julia worked on precursors of Gemini using contextual neural techniques before they were called “RAG” (and applied it to products like Google Keyboard and Pixel phones). Mihail built the earliest LLMs at Amazon Alexa and launched the first contextual deep learning conversational AI system in production at Alexa.
