Northvector
Evaluation and observability for production AI systems.
Overview
Northvector builds the measurement layer for teams shipping AI into production. Its platform captures every model call, scores outputs against task-specific rubrics, and surfaces regressions before customers find them.
Northvector applied in 2023 with two engineers, no revenue, and an inference bill that was about to end the company. They were approved in three days. The credits covered eighteen months of evaluation runs, and the mentor they were matched with had built the same category before.
What Stackpass unlocked
-
01
Compute they could not have afforded
Evaluation is inference-heavy by definition. $180,000 in credits across cloud and model providers turned an impossible burn rate into a runway they could plan around.
-
02
A mentor who had built the category
Weekly sessions on rubric design and enterprise packaging with an operator who had shipped evaluation infrastructure at scale.
-
03
The introduction that led the seed
One curated introduction from the capital track became the term sheet they signed four months later.
“Stackpass committed in a week when everyone else wanted another quarter of data. That decision is the reason the company exists.”
