When a startup begins its journey, data is often scattered across various tools, systems, and spreadsheets. However, as the business grows and its operations become more complex, the need for a structured approach to data becomes unavoidable. This is where the first data expert enters the picture—a pivotal hire that often shapes the company’s data culture and infrastructure for years to come.

For many startups, this first data hire comes after a successful seed investment round, when resources allow for an initial investment in analytics infrastructure. Increasingly, however, startups recognize the importance of centralized data much earlier in their lifecycle, opting to bring in a freelance data expert even before formal funding. These data champions set up foundational data systems and deliver actionable insights that drive decision-making and growth.

This blog post explores the role of a company’s first data expert, their challenges, and their strategic decisions. Particularly the choice to implement a startup data warehouse as the central hub for all things data.

Why do startups need a data expert early?

Before diving into the specifics of the role, it’s worth understanding why startups need to invest in a data expert early. At the seed stage or even pre-seed stage, startups often operate in an environment of limited resources and high uncertainty. Decisions need to be data-driven, but extracting insights from data can feel like an impossible task without proper infrastructure.

Some of the critical needs a first data hire addresses include:

• Breaking down data silos: Sales, marketing, product, and finance teams often operate in isolation, using different tools to manage their workflows. This results in fragmented data that are difficult to aggregate or analyze.
• Providing clear metrics and KPIs: Founders and stakeholders need to understand the business’s performance at a glance, which requires well-defined KPIs.
• Enabling scalability: A well-structured data warehouse lays the groundwork for advanced analytics, machine learning, and other initiatives as the company scales.

The many hats of the first data expert

The first data expert in a startup wears many hats, combining the skills of a data engineer, data analyst, and often a product manager. Here are the key responsibilities they take on:

1. Setting Up the Data Warehouse

The data warehouse is the heart of a startup’s data strategy. It’s the central repository where all data from various systems is consolidated, cleaned, and organized. For the first data expert, setting up this infrastructure is often the first order of business.

• Choosing the right tool: Cloud-based platforms like Snowflake, BigQuery, and Redshift are popular choices for startups due to their scalability and flexibility. The data expert evaluates these options based on the company’s needs and budget.
• Automating data pipelines: Tools like Fivetran or Airbyte simplify the process of extracting, transforming, and loading (ETL) data into the warehouse. The data expert configures these pipelines to ensure seamless data ingestion.

The goal is to create a system that allows stakeholders to access accurate, up-to-date data without manual intervention.

2. Building a data modeling infrastructure

Raw data is rarely ready for analysis. The first data expert uses tools like dbt (a data build tool) or Dataform (google cloud) to transform raw data into clean, structured datasets that support decision-making.

• Transforming raw data: Using SQL-based workflows, the data expert creates models that aggregate, filter, and join data from various sources to make it analysis-ready.
• Creating a layered data model: With the help of the modeling our champion creates the familiar bronze, silver and gold layers. Thinking about reusability.
• Defining business logic: Every startup has unique definitions for metrics like Monthly Recurring Revenue (MRR), Customer Lifetime Value (CLTV), or User Retention. The data expert collaborates with stakeholders to define and codify this logic in the data models.
• Creating reusable datasets: The data expert ensures consistency and scalability across analyses by organizing data into modular, reusable models.

3. Understanding Stakeholder Requirements

In a startup, the first data hire often works closely with non-technical stakeholders—founders, marketers, salespeople, and product managers—who may have limited understanding of what data can and cannot do. This creates a unique set of challenges:

• Managing expectations: Stakeholders often have high expectations, hoping for instant insights or predictive analytics. The data expert must balance these demands with the reality of building a robust data infrastructure from scratch.
• Facilitating communication: By translating technical concepts into business-friendly language, the data expert ensures stakeholders understand the value of their work and align on priorities.
• Identifying quick wins: To build trust and demonstrate value, the data expert focuses on delivering early wins—actionable insights or reports that address pressing business questions.

4. Delivering Insights and KPIs

In addition to setting up systems, the data expert must provide insights that drive decision-making. This often involves:

• Designing dashboards: Using tools like Looker, Tableau, or Metabase, or Mitzu, the data expert creates dashboards that visualize KPIs and track performance over time.
• Generating reports: From churn analysis to campaign performance, the data expert generates detailed reports tailored to stakeholder needs.
• Telling a story with data: By contextualizing numbers with business insights, the data expert helps stakeholders understand not just what is happening, but why.

5. Bridging the Gap Between Data and Product

A less obvious but equally important aspect of the role is understanding the startup’s product or service. This knowledge allows the data expert to:

• Collaborate with development teams: Whether it’s tracking user behavior in a SaaS application or measuring feature adoption, the data expert communicates data requirements to developers.
• Drive product improvements: By analyzing user data, the data expert identifies opportunities for product enhancements or new features.
• Support growth initiatives: From customer segmentation to pricing experiments, the data expert provides the analytics foundation for growth strategies.

The Challenges of Being the First Data Expert

While the role is rewarding, it’s not without its challenges. Some of the most common hurdles include:

• High expectations with limited resources: Stakeholders often expect a fully functional data infrastructure and actionable insights within weeks, even if the company’s systems are in disarray.
• Wearing multiple hats: The first data hire is often a jack-of-all-trades, juggling engineering, analysis, and strategy. This can lead to burnout if not managed carefully.
• Educating stakeholders: Many founders and team members lack a clear understanding of what data can realistically achieve, requiring the data expert to manage expectations and advocate for a long-term approach.

The Long-Term Impact of a Strong Foundation

A skilled first data expert doesn’t just solve immediate problems; they lay the groundwork for a data-driven culture that scales as the startup grows. By centralizing data, standardizing metrics, and delivering actionable insights, they enable teams across the organization to make informed decisions.

Over time, the startup’s data infrastructure can evolve to support more advanced use cases, such as:

• Predictive analytics: Forecasting future trends based on historical data.
• Machine learning: Building models to optimize processes or personalize user experiences.
• Real-time analytics: Providing up-to-the-minute insights for time-sensitive decisions.
