Sienge + BigQuery
Sienge is the leading technology ecosystem in the construction and real estate industry in Brazil. Used by more than 9,000 clients — including 77 of the country's top 100 homebuilders —, Sienge centralizes construction management, finance, purchasing, contracts, inventory, and after-sales in a single integrated platform. BigQuery is Google's fully managed, serverless data warehouse designed for large-scale analytics. Together, they form a powerful combination for teams that need to turn operational construction data into business intelligence.
With Erathos, you can integrate Sienge data into BigQuery in minutes. Our platform handles the entire process of moving your data to your analytical environment, allowing you to join this data with other sources in your Data Warehouse. This way, your time is focused on what actually drives value — extracting valuable insights and making data-driven decisions.
What Sienge data does Erathos sync to BigQuery?
The integration automatically syncs the main Sienge objects:
Projects (Obras) — daily job logs, schedules, cost estimates, and construction progress
Finance — accounts receivable, bank slips, transactions, and cash flow
Contracts — customer data, units, statuses, and change logs
Purchasing — orders, suppliers, quotes, and purchase orders
Inventory — material movements, balances, and requisitions
Units — real estate properties, developments, delivery status, and after-sales
Why sync Sienge to BigQuery?
Native Sienge reports are useful for daily operations, but they have a clear limit. Moving your data to BigQuery allows you to join it with other sources — sales and marketing data, actual construction costs, quality indicators — to answer questions that Sienge alone cannot. Actual cost per development. Budget variance by phase. Profitability per unit and per product.
How it works
Erathos connects to Sienge via its official API and syncs your data incrementally — only new or updated records are processed in each run, keeping pipelines fast and BigQuery costs predictable. You choose the sync frequency (ranging from 5 minutes to daily), the objects to sync, and the target dataset. Every run is logged with full observability: runtime, rows processed, errors with context, and instant alerts via Slack or email if anything goes wrong. No black box. No surprises. Full control.
No credit card required.

Bruno Rosso
Data Analyst
Every new source implementation, if I had to do it alone, would take me about two or three months. With Erathos, it's done in a few hours. I don't need a data engineer's skillset to deliver real value with company data.

Luis Ribas
CTO
I can describe my experience with Erathos as seamless; we had no major issues migrating from our old data pipeline platform. Their support is always impeccable, both in answering questions and resolving issues. I highly recommend them, without a doubt.

Sayuri Valente
Project Manager
The robustness and efficiency of Erathos's connectors—whether for Meta, Google, RD Station, or ERPs like Bling and Conta Azul—make the entire pipeline much faster and more reliable. The technical documentation is extremely well-crafted and intuitive, which greatly legacy simplifies implementation.

Kauê Raizer
Co-founder
Centralizing our data with Erathos gave us a roadmap to structure the company: today, we can view NPS and churn in a consolidated way and use that to drive decisions. If I were to give advice to another founder, it would be: centralize your data from day one.

Matheus Nunes
CTO & Co-founder
Erathos revolutionized data management at WE. By integrating multiple SaaS platforms into a single DW, our engineering team can now focus on the core business. We implemented dashboards providing insights across all departments, enriching our data culture and streamlining decision-making.

Fernando R.
Head of Data
Erathos brought an incredible boost in productivity. With no worries about data ingestion, the team focused on strategy rather than pipeline maintenance. Implementing a new connector takes minutes, and the reliability is outstanding. It was one of the best decisions we've made.

Carlos Schwabe
Co-Founder & CDO
We used to have a lot of rework, but not anymore. Working this way is much more efficient. If it's not your core business, hire Erathos. Spend your time modeling your own domain, not someone else's.

Fernando Costa
CTO & Co-founder
It was impossible to run our operations on spreadsheets. Erathos was a perfect fit: they became the data engineer I didn't have. We managed to reduce analysis time, establish weekly data rituals, and, most importantly, trust the data we use.

Thiago Paz
CFO
If I didn't have this infrastructure, I would need three or four people to do what Erathos does today. I was able to drive real value from my data with a much leaner team than I ever imagined needing.
8
Felipe Corrêa
CTO & Co-founder
Erathos is essential for anyone looking for a quick go-live when centralizing data from multiple sources. We successfully integrated 6 different data sources in a single day, something that would have taken weeks without Erathos.

FAQ
What is Erathos and how can it help my company?
Erathos is a data ingestion platform built for reliability, transparency, and control. We help data teams connect their tools—like Sienge—to their data warehouse, without the maintenance overhead of in-house pipelines or the opacity of traditional ETL tools. Our customers reduce pipeline maintenance by up to 80%.
Does Erathos sync Sienge historical data to BigQuery?
Yes. During the first sync, Erathos performs a full historical load of your Sienge data. From then on, subsequent syncs are incremental—only new or updated records are processed, keeping the pipeline efficient and BigQuery costs predictable.
How often does Erathos sync Sienge data to BigQuery?
You can configure table-level sync frequency from every 5 minutes to daily. Erathos uses incremental syncs, meaning only new or updated records are processed in each run—keeping pipelines efficient and BigQuery costs predictable.
What happens if a Sienge sync fails?
Erathos automatically detects failures and sends alerts to your email, Slack, or Discord with full execution context — not just a 'job failed' message. Intelligent retries handle transient errors, and every run is logged so your team can debug in minutes, not hours.
Is there a free trial available for the Sienge connector?
Yes. Every Erathos connector includes a 14-day free trial. Connect Sienge to BigQuery and start syncing immediately — no credit card required.
