Five years, I left BREX in August. The airline is truly genuine. I joined a Brex when three years old, and I can still remember my first day. At the same time, those five years felt very long. All of this is because of extensive knowledge that I have benefited, to join a small group of data and to learn full data, work with functions, GTM, and productivity. This accelerated growth is one of the major benefits of starting as a data scientist.
“Will I join the start or the most inventory company?” I hear this question on my network at all times. In this article, I will share scientific health at first based on my experience. Hopefully this will help you to navigate your work manner.
Quick Note: “Start” is a broad name that includes many types of companies. In the context, Brex is the first-based Finttech beginning that provides corporate cards, bank services, business Customs Cost Cost Software. I joined the Brex after three years of full experience in product data science. At that time, Brex was a series of three years of C Cecid criction by 500 + Cesers. Therefore, my experiences can vary from the previous company.
I. VS-Special VS.
The Startups Submit immediately – they need to adjust the techniques based on the market response and the Iterate regularly to ensure product marketing. Data scientists, such as expensive use, need to remove their location of focus correctly to create a very large number of business.
Taking my own experience as an example:
- When I first joined the Brex, the most important thing would boot as many customers as possible while controlling the risk of fraud. Therefore, I worked closely with Anorbing team to improve the flow of account application and improve the distribution of the service group.
- As the foundation of our client we grow, the following was to measure our Custom support work (Cx) to provide the best support. I have joined the CX team to analyze customer pain points and reduce the frictions products. (Read my article to get more information on DS in Cx.)
- Later, I worked together with the Ramps team that ramps are new customers and product team to identify the Churn drivers and improve maintenance.
As you can see, the Startups are very inclined in the annala. In big firms, you may face a feature of one product for years; Initially, company needs can completely change within a quarter, and data scientists change their domains regularly as a result.
Upside that this allows data scientists to check and participate with many tasks and have the fullest view of the business. I worked for almost all groups in the last five years – watching that GTM (going to market) Finded Closed hopes and trainings How to deal with customer points and move. This is a more effective way of understanding business functions than reading books or taking courses at business school. It also ensures that detailed scientists have clear and most impacting questions.
But what is the challenge? Data scientists need to follow the company strategy and adapt to changes regularly. This means changing first things, and sometimes it will build things in a quick way, instead of the best or reliable way. Tech Ret Retle Pires quickly march in one trash and many metric varieties, confusing participants and data group itself. Establish excellent habits, so staying and chaos sometimes cannot be avoided – although you are able to set up standards from 0 to 1 (or see others to do so) and it's a data science leaders.
II. A Data Analyst vs. Data Enginre vs. Sciest data? All of the above.
Tasks Articles in Details These days are confusing – some data scientists focus on testing, while others are deeply in the study of the machine; Some detailed commentators simply form Dashboards, but they mainly make product Analytics. But when it comes to starting, articles are a little important – you will do everything.
When I joined BREX, everyone had the same subject, “Data Scientist”, but we should all wear many hats. We separate the data team into DS, DA, and de de apply only from the beginning of the past year. As I said above, the Startups were tend to go to the goal. Therefore, when there is limited power and no clear group structure, you will have to do everything to achieve purpose.
- Data engineering: I have learned data moderation, air load, ETL processes, SQL functioning, other data engineering skills over the last five years. I remember one of my first projects in Breex was to move our data pipes from DBT to the internal tool. Yes, as a Data Scientist at the outset, there is a highest chance and you need to build, own, and maintain your data pipes.
- Previews: Join start means that there are many business unports or minimum data support. Therefore, to help the party understand their performance and get their trust, the first step (after he has built data pipelines) to describe the metrics successful and build Dashboard. When metrics are highly considered, questions such as why they can either move or motivate them naturally. All of these are the general fields of analytics.
- Data science: There are also high-quality data charges that apply the charges at the beginning. The typewriter is helpful to illuminate, predict the Churn, to predict LTV (the value of life's health), etc.
Is it a good or bad thing to wear many hats?
If you have not been sure what kind of data is very interesting, join the start will help you get the whole taste and decide which way to go next. Or if you would like to be the main head of the data or build your company one day, this full display is very important.
At that time, the lowest is clear and – you will spend time in the wrong things, or not related to your long-term work goal. The fact that you own all data life and you can confuse participants, because they usually care about some form of output, for example, Deskboard or models, but they don't see that you need to spend another 50% of the data pipelining.
III. High look
Data scientists at first are never able to be seen. From the first day of Brex, I have to work directly with C-Suite. Leadership often come to you with questions urgent and important business, hoping that you can make the magic of data access to and call business growth. This is not something that you are often experiencing in the established company, especially as a data scientist in Junior. It is a higher stress but the leaky environment.
For example, during the Silicon Valley Bank Crisis on March 2023, many startups were affected, facing the risk of losing their work money. I also worked hard with the leadership team to help start survival in this difficult time. I have created a real time tracker on new customer applications, analyzing the speed of review of the additional employees' requirements, and interact with other DS to speed and accelerate onbearding checks. It was a sharp weekend, working with active crossing in the military (almost brings) from 8am to midnight. However, this is one of my wonderful memories in BREX, showing the achievement of true customers in our leadership, and how data scientists can file a huge business impact.
Iv. Exposure to new tools
The start of the teenager is also brave enough to try the new tech stack. Therefore, generally are the first energy of new tools, while large companies can take months (and layers of approval) before driving aircraft, excluding the larger expenses of immigration.
For example, in my time in brex,
- We started exploring the Illm testing charges in the data science two years ago, and they can access all the llm apis (Openai, and Gemini) open to everyone. Every year, IBREX hosts the internal Hackathon and encourages employees to remove. Two years ago, I partnered with an engineer to create a platform for Ai-Powered Repeent to automatically distinguish, summarize, and analyze various data for various reply. Last year, I built a rag based chatbot to help participants to find a customer's response to a specific product feature. This year, I worked with data details testing Text-to-SQL skills in Calaudude and Snowflake CLI. I totally enjoyed these opportunities to use the edge of the edge of the Data Science sprissim.
- We often drive new data solutions. For example, we were the first hex customer for the books of partnerships and the data sharing. We use Statig to test the event tracking. We also tried a variety of ai-powered Business Intelligence for better performance analytics.
Working at the beginning helped me to stay new technology and accepted my daily walk. That didn't do a more enjoyable work but kept me competing as the industry appears.
On the flip-side, the finding of a retention may mean disrupt the movement of the work and reorganization of infrastructure. It also means an invisible development experience.

Therefore, you should join at the beginning or the most inventory company?
The Startups provide speed, variety, visibility, and cut exposure. But they also bring chaos, convert the priorities, and the need to wear hats may not enjoy it. If you thrive in the bottom and heat to speed up your curve, the start can be the amazing place to grow as a data scientist.
For me, five years in Breen taught me the amazing amount of business and data. I will thank you forever for the lessons, people, and the opportunity to see which data science looks like a quick start.
