Every firm deep-researched by agentic AI, scored for potential and scoop, and fact-checked before publish.
75 firms this week: operational AI agents, industrial carbon tools, and lab robotics releases
Operational AI agents handling design, audit, and clinic calls. A former NVIDIA design lead sells on-prem agent platforms to top chip firms. A European audit startup adds source vouching and recalculation to its agentic testing stack. A Maastricht team fields LLM agents that answer 30 to 50 percent of missed inbound calls at hearing clinics and book appointments.
Industrial carbon tools retrofitting kilns and coating chips. Mafix activates silicates through thermal ion exchange in cement kilns to produce silicon fertilizer that captures 2.7 tons of CO2 per hectare in field trials. HexSeed deposits CO2-derived diamond films onto finished GaN devices to cut heat losses in data-center power modules. A Canadian recycler processes rare earth magnets from e-waste into mixed oxides under contracts with magnet makers.
Lab robotics releases targeting swarms, low-cost hardware, and embodied tasks. A Montreal lab's decentralized SLAM repo reached 650 GitHub stars after ESA and DARPA tests. A Sherbrooke team published full CAD, firmware, and ROS code for an autonomous plasmid assembly pipeline on a UR3 arm. A Toronto student delivered a complete open-source electrochemistry robot built for under 500 dollars.
The rest of the issue covers health data aggregation, defense interceptors, payments processors, and commerce graphs.

Scores run 0 to 100. Potential: how likely the firm is to become a real winner, judged across the six dimension scores and held consistent with them, whether or not anyone has heard of it. Scoop: how unlikely a well-read tech investor is to have heard of it yet. High means it has not reached the outlets that reader follows, whatever the firm's quality or age. How our top potential scores did.
