Enterprise Planning Architecture, Finally Built to Scale.

Fintastic is an enterprise planning and analysis (FP&A / EPM) platform engineered architecture-first: a density-agnostic engine for sub-second calculations, unlimited concurrent scenarios, and a single model that handles enterprise-scale complexity without compromise.

01 / The problem

Most Platforms Work Until Complexity Catches Up with Them.

Models split. Performance slows. Scenarios become a luxury teams cannot afford. The patterns are familiar, and they are not team problems:

Calculations that take forever

The requirement is seconds, but recalculations stretch into minutes or hours as datasets grow.

Models fragmented everywhere

Logic scattered across files, modules, and disconnected sheets just to keep the platform usable.

Concurrency that freezes

Concurrency during planning cycles causes the platform starts to lock up.

Cycles that drag

Long planning cycles inside a company that needs instant answers.

These aren't team problems. They're architecture problems. Fintastic was built from the ground up to remove them.

02 / Computation engine

Plan as complex as you need, without slowing down.

Model the whole business at any level of detail. As you add dimensions, data, and calculations, the model stays fast and stays in one piece. No slowdowns, no rebuilds, no splitting into separate models.

No ceiling on scale

Handles far more dimensions, data, and calculations than other platforms can.

Performance that holds

Stays fast, even as plans get more complex.

One model, never fragmented

No separate models to build, move data between, or reconcile.

How it works

One engine handles both dense and sparse data, and detects which is which automatically. There is no routing layer and nothing for you to select.

Whatever you send, the engine picks the structure. You don't.
Dense Data Example:  Monthly P&L by department
Every department has a number in every month. Almost no gaps.
Sparse Data Example:  Sales by product, customer, region
Most product-customer-region combinations never happen, so most cells are empty.

Multi-entity models are calculated in a single operation, not entity-by-entity. Calculations complete in seconds regardless of model size, dimensionality, or concurrent user count. This is not a performance target. It is an architectural characteristic.

03 / Adaptive modeling

Models That Represent Your Business, Not a Simplified Version of It.

Traditional platforms impose structural constraints: predefined dimensions, rebuilds on schema changes, new models for every new business line. Fintastic eliminates that trade-off.

Arbitrary dimensionality

No hard limit on dimensions, members, or hierarchical depth. No need to create artificially concatenated dimensions.

Flexible schema

Structure follows your business logic, not platform module boundaries. No rigid templates.

Single model instance

Finance, revenue, workforce, marketing, IT, and operations live in one model. Change one assumption and every dependent calculation updates immediately.

Structural evolution without rebuilds

Add a product line, enter a market, or reorganize. The model adapts. You do not start over or call a consultant to restructure.

04 / Versioning architecture

Every Scenario Is Fully Isolated. Every Calculation Is Independent.

On most platforms, scenarios share compute and memory, so adding versions degrades performance and locks users out. Fintastic works differently.

Versions share memory and compute

Each version is fully isolated

Adding versions slows the platform

Performance stays constant at any version count

Comparing versions requires matching structure and dimensionality

Users are locked out during calculations

Users can perform parallel updates across all versions simultaneously

Cloning takes minutes or hours

Near-instant cloning with all logic and structure preserved

3–5 active scenarios is a practical limit

No limit on concurrent versions

05 / Data architecture

Continuous Synchronization. Not Overnight Batches.

Continuous synchronization keeps the model live. Only what changed is processed, so updates are fast and the numbers are always current.

⇄ Incremental ingestion

New and changed records are detected and ingested continuously. The platform does not reload entire datasets to reflect an update.

◎ Targeted recalculation

Only the calculations affected by a change are recomputed. A single actuals update does not trigger a full-model recalculation.

06 / Modeling language

Powerful Enough for Complex Logic. Learnable in Weeks, Not Months.

Expressive enough for complex logic, approachable enough that analysts build and own models without engineering support.

Fintastic visual formula builder designed for finance and business users

Expressive logic

Handles complex, multi-dimensional business rules without workarounds or external scripts.

AI-assisted formula building

Describe the intent and the platform helps construct, validate, and explain the formula.

Productive in weeks

New builders reach production-grade output in three to four weeks, not months.

07 / Embedded intelligence · Smartastic

AI That Operates Inside the Model, Not on Top of It.

Smartastic works on the same data, formulas, and permissions your team uses every day. No separate data layer, no exported copy, no hallucinated numbers.

Ask in plain language. Smartastic answers from the live model, with the logic behind every number.

structural awareness

It reads your model, not a flat table

Understands dimensional structure and formula dependencies, so answers reflect how the model actually works.

permission-aware

Inside the permission boundary

Respects entity and dimension-level permissions, not as a post-filter. Users only see what they are allowed to see.

natural language

Live answers, no export step

Ask questions in plain language inside the tools you already use, including Slack.

formula assistant + docs

Build faster, document automatically

Builds and explains formulas and generates model documentation on demand.

Every answer is grounded in the live model, so the number you get is the number in the plan.

08 / Governance & security

Granular Controls. Full Auditability. Enterprise Certifications.

Control, isolation, and auditability are structural characteristics of the platform, not bolt-on features.

🔒 Access control and auditability

Cell-level permissions across entities and dimensions

Data masking for sensitive figures

Version isolation with role-based access control

10 / Technical FAQs

Platform Architecture, Answered

Can we consolidate multiple disconnected models into one?+

Yes. The adaptive modeling architecture supports arbitrary dimensionality without rigid modular constraints, so your entire business can operate within a single model instance. In one enterprise implementation, a customer consolidated from 5 disconnected models into 1 fully interconnected model with no performance trade-offs. This is one of the most common migration patterns we see.

How does Fintastic perform in a head-to-head evaluation?+

We encourage structured proof-of-concept evaluations using your actual data and requirements. In these evaluations, Fintastic has consistently delivered results in seconds, with customers reporting calculation improvements of up to 80x. We can set up a POC so you can benchmark performance directly against your current platform.

How much of the implementation can our team own?+

The platform is designed to be self-serve and low-code. In enterprise implementations, internal teams have driven 80%-90% of the build. Model builders with no prior enterprise planning platform experience have onboarded in 3-4 weeks and built production-grade structures independently.

How does the AI differ from what other vendors offer?+

Fintastic AI operates directly inside the planning model, on the same data, formulas, and permission structures your team uses every day. It understands the model's dimensional structure and formula dependencies. It respects entity-level and dimension-level permissions, not as a post-filter. That means no hallucinated numbers, no answers that contradict what the model shows, and full traceability.

How many concurrent users without performance degradation?+

The platform supports unlimited concurrent users in complex enterprise models with no degradation. The architecture handles parallel access natively with no locking, no queuing, and no version conflicts.
