Bringing Quality and Observability to
Big Data Ingestion

Upsolver's mission is to accelerate the delivery of big data
to the people who need it.

To achieve this, we invented cloud-native technology for ingesting batch and streaming data with built-in quality and observability. By addressing data quality issues as data arrives, Upsolver eliminates the time and complexity of delivering trustworthy analytics, without compromising on data freshness or scale.

Who We Are

Upsolver is a closely-knit group of data engineers and infrastructure developers who are obsessed with making big data ingestion pipelines so easy to create that any data practitioner could do it, even when dealing with streaming and complex data at big data scale. We built the first version of Upsolver for our own use, and enjoyed eating our own dog food so much that we decided to bring this value to every company doing analytics in the cloud. We now claim numerous companies as customers spanning industries as diverse as oil & gas to gaming, feeding both operational analytics and customer-facing data products.

What we lost in the transition to big data

In the early days of Upsolver we recognized that something important was lost in the transition to big data. Decades ago, databases were invented to abstract away the complexity of coding over raw file systems, letting data teams “speak” in schemas and SQL, which let them transform data more easily and iterate faster.

Upsolver’s goal is to re-invent the simplicity of a database on top of the tremendous economic and “power at scale” advantages of the cloud. That is why we focused on either no-code, or low-code using SQL as the lingua franca for designing pipelines, and for data lake transformations why we automate all of the plumbing that takes most of the time.

By eliminating any compromise across the dimensions of power, simplicity and affordability, we are transforming the data pipelines that power cloud analytics workloads. Data engineers who use Upsolver become much more productive, delivering data pipelines that normally would have taken months, in hours. Plus, SQL-savvy data consumers such as data analysts, analytics engineers and data scientists now can ingest and transform complex raw data, without having to become data engineers.

Realizing the potential of the cloud

This will widen the aperture of analytics, unlocking data that heretofore has been difficult to analyze. System logs, clickstreams, IoT sensor feeds, and other continuous data sources will be blended with static and historical data to create query-ready data sets that feed reporting or ad hoc queries with unmatched data freshness, as well as customer-facing data products.

Upsolver Core Values

Earn customers’ trust

Always remember that our customers are actually partners for the journey. They provide the feedback required for building the product, they tie their good name to Upsolver’s success and they provide the funds to run the business. Earn their trust by creating value proactively and continuously. Always! be respectful, quick-to-respond and honest, even if it’s uncomfortable.

Treat the company like it’s yours

Take initiative, own issues and resolve them. Instead of saying “it’s not my job” or optimising for short-term results, hold yourself and others accountable for Upsolver’s long-term success. Give feedback and be open to get feedback since we are all working for the same goal.

Disagree and commit

Harmony can be the enemy of excellence and quality. Challenge decisions and deliverables when you disagree, even when doing so is uncomfortable or exhausting. Be tenacious and don’t compromise for the sake of social cohesion. Once a decision is determined, commit wholly.

Obsessively listen

Customers are aware of the problems they want to solve. Obsessively listen to them and ask questions until you truly understand their pain points and what caused them. Don’t block yourself from feedback even if it conflicts with your basic assumptions about our offering. Where there is pain, there is opportunity.

Simplify and invent

Big data is a very complex field so don’t expect customers to just give you solutions to their problems. Be creative by eliminating steps and options that don’t add value to the process. Surprise customers with solutions that are an order of magnitude easier compared to what they know.

Create the best technology for big data

People are used to managing a tradeoff between ease-of-use, cost and flexibility. Growing fast requires we change the “laws of physics” for big data and cancel this tradeoff using the best technology in the market. Always insist on the best possible processing performance, the lowest possible infrastructure cost, elastic scaling and flexibility to implement any data processing use case.

Integrity first

Treat your co-workers, customers and partners like you would like to be treated yourself. Never discriminate, cheat or insult. Create a fun and professional workplace which you would want your closest family to work for. When you make a mistake and you will, communicate it, find a way to fix it and move on.
