# How Linus sustains fast growth with a lean data team

> Linus's rapid growth meant every report took a month of manual work. Here's how Erathos automated that operation and freed up the team's time for strategic decisions.

Linus is a Brazilian brand of vegan, recyclable, and sustainable sandals, founded by Isabela Chusid in 2018. It is a Certified B Corp, with 100% domestic production and an international presence in more than 10 countries across Europe, Latin America, and Oceania.

Linus, a Brazilian brand of vegan, sustainable sandals, is going through a phase of rapid growth, opening new stores and relying more and more on data-driven decisions. Before Erathos, the company used an ingestion tool that got discontinued, and generating reports took roughly a full month of work for two people. Today, with Erathos handling ingestion, Data Engineer Lucas Galvão leads the entire data operation with a lean, automated setup, without needing to hire another senior team member.

## The results

- **40%** — of working time saved since Erathos took over ingestion.
- **3 months** — of effort saved since hiring Erathos.
- **1 day** — to have all the data ready, when the process used to take up to a month.

## The challenge

Linus is growing at a fast pace, opening new stores and making increasingly frequent decisions about where to expand and how to improve the customer experience. That growth made the previous reporting model unsustainable: a manual process that took roughly a full month of work for two people every time the analyses needed updating.

Before Erathos, the company was already using an ingestion tool, but it was an all-in-one ETL and analytics solution, not specialized in data ingestion, and it ended up being discontinued, leaving Linus without a reliable data infrastructure right when it needed one most to sustain its growth.

Lucas Galvão joined the company with a clear goal: automate report generation. He knew that without a solid ingestion solution, he'd need at least one more senior person on the team, and it would still take much longer to get everything running, close to a year to rebuild what the company has today.

## The solution

Lucas learned about Erathos through a referral and already had prior experience with the tool from a previous job, which gave him confidence to adopt it quickly at Linus. He had worked with open-source Airflow before and chose not to go that route again, given the maintenance burden that kind of solution usually demands. If you want to know more about how Erathos compares to open-source ingestion solutions, there's a direct [comparison between Airbyte OSS and Erathos](https://www.erathos.com/vs/airbyte?utm_source=case-study&utm_medium=referral&utm_campaign=linus).

With Erathos handling ingestion, Lucas structured the data warehouse by organizing incoming data into bronze, silver, and gold layers, with SQL-based modeling. The company's core systems are automatically updated every 12 hours.

## The results

- A report that used to take roughly a full month of work for two people is now generated automatically, with security, reliability, and observability
- Lucas estimates having saved about 40% of total working time and around 3 months of effort since taking over the data function alongside hiring Erathos
- Without Erathos, the company would need at least one more senior person on the team just to keep ingestion running
- Technical support responds quickly whenever a bug comes up, giving Lucas confidence that he doesn't need to worry about ETL maintenance

## What's next

Linus keeps evolving the maturity of its own data stack, with Lucas testing new ways to consume what's already structured. If you also deal with the pain of maintaining ingestion pipelines by hand, [try Erathos for free](https://app.erathos.com/signup) and see what it's like to have your data ready without needing to hire more people for it.

> ETL maintenance would be the biggest problem if I didn't have Erathos. Today I don't need to worry about that. The cost-benefit is excellent, it makes sense given the software engineering team they've built and the engineering support. I've never had a headache with the Erathos team, I've had issues with other service providers before, and that doesn't happen with Erathos.

If I had to run all the ETLs by hand, I'd need at least one more senior person on the team and development would fall way behind. Thanks to Erathos, I have all the data ready within a day, if it weren't for that, it would take a month. And whenever I need changes, the Erathos team is fast.

> I believe I've saved about 40% of all the time I've worked. I joined the company right when they hired Erathos, and I figure I saved about 3 months of work, focusing instead on tool configurations and tough technical decisions. I don't get surprised by costs, it's predictable, and that even improves the relationship with finance.
