Building on Snowflake vs. Buying Aquata: A Decision Framework
Snowflake is a legitimate, widely adopted data platform. BlackRock’s Aladdin Data Cloud runs on Snowflake. State Street Alpha is powered by it. Dozens of asset managers use it as the foundation of their data infrastructure. The question firms face when evaluating Snowflake is not whether it is a capable technology; it is, but whether building an investment data platform on top of it is the right use of engineering resources, capital, and time. This page is for firms actively considering a Snowflake-based internal build as an alternative to purchasing Aquata. It is a genuine comparison, not a dismissal. The right answer depends on your firm’s engineering capacity, timeline, strategic priorities, and how you value operational independence versus speed to value.
Note: Information on Snowflake’s platform capabilities is based on Snowflake’s public documentation, product announcements, and independent market analyses reviewed March 2026.
What is Snowflake?
Snowflake is a cloud-native data warehouse that provides scalable storage, compute, and a growing suite of AI and analytics capabilities, including Cortex AI for Financial Services, launched in October 2025. It is one of the most widely adopted data infrastructure platforms in financial services, used by major asset managers, banks, and hedge funds as a foundation for data engineering, analytics, and AI workloads.
Snowflake excels as a horizontal infrastructure layer: high-performance query execution, elastic scaling, and a data sharing model that enables collaboration across organizations. It does not have an investment domain data model, pre-built connectors to prime brokers or fund administrators, investment-specific data quality rules, or an operational workflow layer. Everything beyond storage and compute has to be built, maintained, and evolved by your own engineering team.
That distinction matters. The decision to build on Snowflake is not a decision to buy a data platform. It is a decision to become a data platform company alongside being an investment management firm.
Evaluating a Snowflake-based Build in a Changing Data Environment
Investment data environments have become more complex. Firms increasingly operate across public and private markets, with data flowing across front, middle, and back-office functions. The tools that generate data, the counterparties that provide it, and the regulatory requirements that govern it all evolve continuously.
As a result, evaluating a Snowflake-based build is less about Snowflake’s capability as an infrastructure platform, which is well-established, and more about whether your firm has the engineering capacity, domain expertise, and time horizon to build and maintain a production-grade investment data platform on top of it, and whether that investment is the best use of your resources.
Understanding a Snowflake-based Investment Data Build in Practice
Domain data model: building from a blank schema
Snowflake provides a blank, general-purpose data schema. Your engineering team defines every entity, relationship, calculation, and data quality rule relevant to investment operations. Investment data has significant domain-specific complexity: security master conventions, prime broker reconciliation formats, fund administrator data structures, corporate actions handling, and asset class-specific calculation logic all require investment domain knowledge to model correctly. Getting to production-grade domain coverage requires hiring and retaining engineers who understand both cloud data architecture and the investment lifecycle, a combination that is expensive and slow to build.
Connectivity and integration: a custom engineering project per source
Every data connection in a Snowflake build, to prime brokers, fund administrators, custodians, market data vendors, and internal systems, is a custom engineering project. Each integration requires design, development, testing, and ongoing maintenance as counterparty data formats change. Firms evaluating a Snowflake build should assess the full integration scope across all counterparty and vendor connections, and project the engineering time required to build and maintain each one. Pre-built connectors in a purpose-built investment data platform address this at the domain level rather than the infrastructure level.
Maintenance: a permanent engineering cost, not a one-time project
Building on Snowflake produces a system your firm owns and must maintain indefinitely. As Snowflake releases new features, pricing changes, or architectural updates, and as investment strategies, counterparties, and regulatory requirements evolve, your engineering team is responsible for keeping the build current. That is a recurring cost that does not diminish after go-live. Upgrade planning, query optimization, and ongoing governance require sustained engineering attention. Managed upgrade cycles in a SaaS delivery model transfer that responsibility to the vendor.
A Broader Shift in Investment Data Platforms
Firms are increasingly distinguishing between infrastructure decisions and investment data strategy decisions. Snowflake is an infrastructure platform; an investment data platform is a domain solution. These are different things and conflating them leads to engineering programs that take longer and cost more than anticipated.
The question is not whether to use Snowflake. Many firms use Snowflake effectively, for analytics, BI, and data science workloads on data that has already been governed and normalized elsewhere. The question is whether Snowflake, with a custom build on top, can replace a purpose-built investment data platform, and whether the engineering investment required to make it do so is the best use of the firm’s resources.
For most investment management firms, the answer is that engineering capacity generates more value when applied to investment-differentiated work than infrastructure construction.
Why Firms Choose Aquata over Building on Snowflake
Firms evaluating a Snowflake-based build are typically weighing speed to value, engineering cost, and long-term maintenance against the flexibility of building from scratch.
- Investment domain expertise is pre-built, not assembled over years: Aquata’s investment data model, pre-built connectors to counterparties and market data vendors, and domain-specific data quality rules represent years of accumulated expertise. A Snowflake build starts with a blank schema. Getting equivalent domain coverage requires hiring and retaining engineers who understand both the technology and the investment lifecycle.
- Time to value is measured in weeks, not years: Aquata can be deployed in components to deliver incremental value from the outset. A Snowflake-based internal build typically requires 12 to 24 months before reaching production-grade capability for investment operations, assuming experienced engineers, clear requirements, and no significant scope changes.
- Maintenance is a permanent cost, not a one-time project: Building on Snowflake produces a system your firm owns and must maintain indefinitely. Aquata’s managed upgrade cycles and SaaS delivery model transfers that responsibility to Arcesium, so your engineering capacity is not consumed by infrastructure upkeep.
Strategic Fit
A Snowflake-based investment data build is the right choice for a specific profile: large technology organizations with many experienced data engineers, investment strategies with highly non-standard data requirements that packaged products cannot accommodate, existing Snowflake infrastructure that is already mature, and a multi-year technology horizon that justifies the build investment.
For most investment management firms, particularly those growing, running complex multi-asset operations, or seeking to reduce engineering overhead, a purpose-built platform delivers faster time to value and a more direct path to operational capability.
Choosing the Right Approach
The most important question is not whether Snowflake is a capable technology, it is. The question is whether your firm’s engineering capacity is best spent building and maintaining investment data infrastructure or applied to work that is more directly differentiated for your investment operations and strategies.
Snowflake is not a reason to avoid Aquata. The two are not mutually exclusive. Several Aquata clients use Snowflake downstream for specific analytics, BI, or data science workloads where Snowflake’s query performance and data sharing capabilities add genuine value. The question is whether Snowflake, with a custom build on top, serves as the investment data layer, or whether a purpose-built platform like Aquata handles that domain, and Snowflake sits downstream for the workloads where its infrastructure strengths are most relevant.
Aquata also connects directly with Opterra, so operational and investment data share a consistent, validated source of truth without a separate synchronization project.
Pricing Considerations
Aquata follows a consumption-based pricing model, allowing firms to scale usage in line with data volumes and workflows.
When evaluating a Snowflake-based build, firms should consider costs beyond infrastructure consumption. Snowflake compute and storage costs are generally visible and measurable, but they represent only one component of the overall investment.
Additional costs include the engineering resources required to build and maintain pipelines, integration development for counterparties and vendors, investment domain expertise to define data models and quality rules, ongoing query optimization, platform governance, and the operational effort required to maintain and evolve the platform over time. Firms should also consider the opportunity cost of allocating engineering capacity to infrastructure development rather than investment-differentiated initiatives.
Alternatives to Building on Snowflake
Firms evaluating alternatives to a Snowflake-based investment data build are typically comparing how different approaches balance engineering investment against speed to operational capability.
At this stage, the focus often shifts to a small number of questions: whether a purpose-built platform can accommodate the firm’s specific data requirements, how quickly it can be deployed, and whether the total cost of ownership, including engineering time, integration development, and ongoing maintenance, is lower than building from scratch.
Snowflake is a strong infrastructure choice for many workloads in investment management. The question is whether it is the right foundation for an investment data platform specifically, and what it takes to build and maintain one on top of it.
This is the context in which platforms such as Aquata are typically considered.
