Case Study / Financial SaaS

Building a multi-tenant profit platform from eCommerce financial logic.

Pentane needed to turn a founder's spreadsheet model into a connected SaaS product. Hatchery helped build the calculation engine, data mappings, interfaces, AWS foundation, testing path, and ongoing product releases.

Pentane

Financial SaaS partnership with Pentane beginning in 2023.
Spreadsheet-based financial logic translated into software calculation workflows.
Commerce, advertising, accounting, and P&L data mapped into one operating model.
Current work supports Pentane 4.0, broader test coverage, and Plenum data/API pathways.
Problem

Sales were visible. Profit needed to be trusted.

eCommerce operators can see orders, ad spend, and platform metrics, but the true profit story often lives across disconnected systems. Pentane needed software that could turn a proven financial model into live guidance.

Risk

Bad financial signals lead to bad growth decisions.

If product cost, advertising spend, channel data, accounting entries, and margin logic do not line up, teams can scale the wrong campaigns, cut the wrong spend, or misunderstand where profit is actually created.

Hatchery role

Hatchery helped turn the model into an operating product.

The work connected the math, data, UX, security, hosting, and release path behind Pentane so operators could move from spreadsheet analysis to a live multi-tenant SaaS product.

Comparison

Spreadsheet model vs. operating SaaS platform

Need Spreadsheet-based work With Pentane
Financial logic Formulas are powerful but difficult to operate across many customers. Calculation workflows turn the model into repeatable product behavior.
Data sources Commerce, ads, accounting, and P&L data stay disconnected. Inputs are mapped, normalized, and connected into one financial view.
Multi-tenant use A model is difficult to reuse safely across different businesses. Separate organizations, roles, data boundaries, and customer-specific mappings support SaaS delivery.
Decision support Teams manually inspect disconnected metrics. Contribution margin, breakeven ROAS, CAC, ROAS, and scenario guidance are surfaced inside the product.
Validation Manual review catches issues after the fact. Reconciliation, targeted tests, and expanding end-to-end coverage support calculation confidence.
Distribution Profit signals stop at reporting. Plenum pathways can use financial signals to support media distribution beyond the major ad platforms.
What Hatchery built

Built as one product system.

Strategy, design, code, integrations, infrastructure, and operations move together so the product can launch and keep serving customers.

Financial calculation engine

Software workflows that translate Pentane's financial model into contribution margin, breakeven ROAS, CAC, ROAS, and scenario guidance.

Data mapping and integrations

Connections and mapping logic for commerce, advertising, accounting, and P&L data across different customer environments.

Multi-tenant SaaS foundation

Customer organizations, roles, security boundaries, interfaces, reporting paths, AWS infrastructure, CI/CD, and ongoing release support.

Plenum data pathways

API and data work that helps Pentane use profit signals for broader advertising distribution across open-web media channels.

Decisions

Product choices that made the work hold together.

01

Preserve the financial thinking

The value was not only the code. The product had to preserve Pentane's operating model while making it easier to use, repeat, and trust.

02

Treat accuracy as a product feature

Financial software has to earn confidence. Reconciliation, testing, and continued refinement are part of the product, not cleanup work.

03

Keep the business outcome visible

The interface has to help teams decide what to cut, hold, or scale instead of simply presenting another dashboard.

Pentane today

Pentane is an active product partnership moving toward Pentane 4.0. Hatchery continues to support financial calculation workflows, data integrations, product interfaces, AWS infrastructure, DevSecOps, automated testing, and Plenum data/API pathways.

What this demonstrates

Pentane shows how Hatchery handles complex product work where math, data, SaaS architecture, UX, security, and operations all have to line up. Pentane reports customer outcomes that include one Shopify brand moving from a $102K monthly loss to $44K in monthly profit within 90 days and another customer reporting more than $3.4M in added revenue.

Hatchery's deep development and math expertise has been a critical part of building and launching Pentane. The fact their team is also domestic makes for significantly easier planning and execution, while also adding flexibility and creativity that are crucial in an early-stage business.

Product evidence

Pentane turns financial data into decisions operators can use.

The product views show the command center, Plenum delivery reporting, and the transformation from spreadsheet logic into an operating SaaS platform.

Calculation workflows behind profit guidance Mapped commerce, advertising, accounting, and P&L data Multi-tenant SaaS roles and customer boundaries Plenum pathways for profit-aware media distribution
A working view of profit, not just sales.
Command center

A working view of profit, not just sales.

The command center brings revenue, net profit, ad spend, contribution profit, efficiency metrics, P&L structure, and trend signals into one operating view.

Why it matters

The value is clarity: operators can see whether growth is creating profit or only top-line activity.

Delivery reporting tied to performance.
Plenum

Delivery reporting tied to performance.

Plenum reporting separates spend, impressions, visits, conversions, CPA, CTR, CPC, and CPM so advertising performance can be read against operating outcomes.

Why it matters

The value is control: paid media can be evaluated with clearer signals instead of relying only on isolated ad-platform views.

From spreadsheet logic to a product system.
Product transformation

From spreadsheet logic to a product system.

A complex spreadsheet model becomes a clearer software environment with workflows, dashboards, reports, and customer boundaries.

Why it matters

The value is repeatability: a strong model becomes easier to operate across teams and customers.

Complex inputs become a cleaner growth signal.
Signal path

Complex inputs become a cleaner growth signal.

The system has to pull many noisy inputs through calculation, validation, and product design before the customer can act with confidence.

Why it matters

The value is discipline: useful financial software filters complexity instead of passing it straight to the user.
