Building the future of sleep requires us to make data-driven product, operations, and finance decisions. But as a small team, we faced a challenge every scaling company knows well: the flood of random data asks. We needed leverage. So we hired an analyst who never sleeps: Devin AI.
Building the future of sleep requires us to make data-driven product, operations, and finance decisions. But as a small team, we faced a challenge every scaling company knows well: the flood of random data asks.
Even with dbt, Looker, and Snowflake powering our analytics stack, these requests piled up. Our queue of ad-hoc tasks grew faster than we could ship. When a new report looked suspicious, we had to stop everything, investigate, and reassure stakeholders. It slowed us down.
Our Eight Sleep metrics took a hit.
We needed leverage. So we hired an analyst who never sleeps: Devin AI.
Instead of forcing people in the team to funnel every question through our small data team, we integrated Cognition’s Devin directly into our workflows:
The setup only took a couple of hours from getting access to our account to asking Devin my first question via Slack. From there, Devin began fielding real data requests immediately.
A few weeks ago, our brand-new daily sales dashboard lit up with an unusually high revenue number. Theories flew:
Instead of a human analyst burning hours to untangle the logic, we asked Devin to investigate. It traced the Looker dashboard back to the underlying queries, ran checks in Snowflake, and quickly found the culprit: an email campaign that performed better than expected.
The revenue was real. The model was fine. And Devin had defused what could have turned into a fire drill.
Since bringing Devin into our analytics stack, we’ve seen transformative results:
For our small team, Devin has become an invaluable teammate. It’s helped us work more efficiently and make better decisions.
Reading more about how different people approach the AI Analyst problem, it seems there are usually two approaches at opposite extremes.
Our experience shows the future lies in between but towards exploration. AI analysts should be able to:
With Devin, you really get what you put into it 100 fold. Two months ago, Devin started as our Jr Analyst, and is close to becoming our Senior Analyst. We are experimenting with:
Augmenting our semantic layer. Context is king. There’s no reason not to improve your documentation and semantic layer. So we will be trialing adding additional useful context into our dbt yaml files using the meta field. This should help improve how Devin approaches using a dataset.
Building a context/feedback loop. We’re experimenting with building an automated way to provide Devin with relevant data models and context from prior sessions to improve its retrieval. We’re also experimenting with crowd sourcing our knowledge creation by building a Slack bot to ask users for feedback on Devin’s answers. These should help with relevance and groundedness.
Experimenting with charting. Sometimes you just want a quick chart, and you don’t really want to create a new Looker object with a visualization. Devin just launched a Metabase MCP server that Devin can use to create charts and screenshot them back to users in Slack. Check out their guide here.
Our partnership with Cognition has been instrumental. We’re in constant contact through a shared Slack channel, collaborating on everything from semantic layer design ideas to suggestions for Devin’s roadmap.
Together, we’re pushing toward a future where AI analysts don’t just assist, they own the repetitive work, while assisting humans focusing on the highest-leverage problems.
At Eight Sleep, Devin has already proven the model: democratized data, faster shipping, and sharper decisions.
The next frontier is scaling this across the industry. And we can’t wait to see what the future holds.
