Digital Gateway builds an AI platform for employee onboarding, training, and competency assessment that captures how a company's best people actually work. And turns it into a system that ramps everyone else to the same level. Every growing company carries the same hidden risk: real performance lives in a few star employees' heads. When they leave, slow down, or get pulled into training juniors, the whole operation feels it. New hires take months to become useful, the same mistakes repeat, and the "how" never gets written down. Our platform fixes that. We extract the knowledge, skills, and decisions of a top performer and package them into a structured role map — a guided learning track of modules, materials, and hands-on assignments. New and existing employees move through the track, get assessed against real competencies, and are signed off by a mentor when they can actually do the job. Managers see, in one view, exactly what each person has mastered and where the gaps are. The result: new hires reach top-performer level in weeks instead of months, onboarding stops depending on your busiest people, and critical know-how becomes an asset the company owns — not something that walks out the door. Under the hood it's an assessment-and-training engine: define the role, capture the standard, assess against it, close the gaps. We start by embedding with a client to map their key role, then the platform scales that standard across the whole team — and every new role map makes the product smarter. We're a small, remote-first team based in Vancouver, building for companies that hire fast and can't afford six-month ramp times. If you want to help put a real onboarding- and-assessment standard inside every growing company — and get in early while the platform is being built — this is your team.
