Our story

Built by engineers who watched models silently fail in production

Inferpathio exists because model monitoring is still mostly manual — cron jobs, Slack messages, and spreadsheets. We built the lifecycle layer that closes the loop automatically.

Founding story

The spreadsheet that started everything

In 2021, Kevin Nakamura was the ML platform lead at a mid-size financial technology company in Seattle, running a team responsible for roughly 40 production models spanning fraud detection, credit scoring, and customer churn. Those models worked. They just didn't stay working.

Every quarter, someone on the team discovered — usually because a downstream business metric had gone sideways — that a model's input distribution had shifted weeks earlier. The tooling gap was obvious: there was no systematic way to watch 40 models simultaneously, no automated trigger to retrain when drift was detected, and no immutable record of which model version had been running when an incident happened. The team tracked model states in a shared spreadsheet. Retraining was triggered by Slack messages and gut feeling.

Kevin spent two years trying to stitch together MLflow for versioning, Prometheus for metric scraping, and custom Python scripts for drift scoring. It worked — barely, and only as long as the team that built it stayed employed there.

In early 2023, Kevin moved to Seattle's Capitol Hill neighborhood and started building Inferpathio with two engineers from his former team: a full lifecycle platform that handles experiment tracking, model versioning, drift monitoring, and retraining automation as a connected graph rather than four separate tools.

Inferpathio is not a monitoring dashboard. It's not an experiment tracker. It's the connective layer between those things — so when drift is detected, retraining starts automatically, and the new model version is registered with full provenance back to the original training run. The loop closes without a human in the middle.

We're a small, bootstrapped team. We take on customers we can actually serve, not ones we need to fake references for.

How we work

Three principles we don't negotiate on

SDK before UI

Every feature ships as a Python API first. If the SDK is clunky, the dashboard doesn't matter. ML engineers live in code, not browser tabs.

Non-invasive by design

Inferpathio is not a framework. It wraps your existing training code without restructuring it. Your PyTorch loop, your XGBoost pipeline — unchanged. We observe; we don't impose.

Statistical correctness first

We'd rather ship PSI and KS-test with well-documented thresholds than a dozen drift signals that fire false positives and erode trust. One reliable alert beats ten noisy ones.

No feature without a production story

Inferpathio is not a generic ML platform. We don't build model serving, feature stores, or training infrastructure. Every feature we ship is part of the monitor-detect-retrain loop — nothing else.
