Tesora

Build rating models in Excel. Deploy with audit trails.

Version control, trauma studies, and SOX compliance for your rating algorithms. No Python required. Every version saved for on-leveling.

Three pillars of rating governance

Build models your actuaries already know how to build. Version everything for on-leveling. Govern with trauma studies and compliance automation.

What makes us different

The governance features that make actuaries say "finally."

Why pricing teams choose Tesora

Spend less time deploying software. Spend more time updating your models.

Frequently asked questions

Common questions from pricing actuaries.

Build

Excel-native rating models. API-ready in seconds.

Build rating models the way your actuaries already work, in Excel. Define inputs, factor tables, and calculation formulas. Save the model and the API is automatically generated. No Python required. No waiting for IT.

Excel formula engine

Use the formulas your actuaries already know. VLOOKUP, INDEX/MATCH, IF statements, nested calculations, all work exactly as expected.

Factor table management

Upload million-row lookup tables with automatic interpolation and extrapolation. Territory factors, class codes, ILFs, all versioned and auditable.

Typed input schemas

Define exactly what inputs your rater needs. The system validates every quote request against the schema before calculation.

Auto-generated API

Save your model and the REST API is ready. Integrate with Kalepa, Guidewire, or your custom front-end.

Version

Every version saved forever. On-leveling solved.

The biggest pain point in pricing: bringing old rates to current level. Every model version is persisted with full history. In 2050, you can still on-level 2025 rates.

Immutable version history

Every save creates a new version with timestamp, author, and change description. Previous versions are never modified.

Effective date management

Schedule future versions with effective dates. Deploy the new ILF curve for next quarter while today's quotes still use the current version.

On-leveling engine

Take any historical exposure and rate it at any version, past, present, or proposed. The system handles the translation automatically.

Diff and compare

See exactly what changed between any two versions. Factor table diffs, formula changes, input schema modifications.

Govern

Trauma studies. Staleness alerts. Full audit trails.

Nobody else has this. Run your entire book through a proposed rate change before you deploy it. Get AI-powered alerts when factors go stale. Full SOX compliance with dev/test/prod separation.

Trauma studies

Before deploying new rates, run your existing book through the new model. See exactly which policies have the biggest rate changes.

Staleness monitoring

"Your territory factors haven't been updated in 10 years." AI monitors factor freshness and nudges actuaries to review.

Test case validation

Generate 1,000 test cases automatically. Run them through every model version. Catch regressions before they hit production.

SOX compliance built-in

Dev, test, and prod environments with role separation. Full audit trails, who changed what, when, and why.

Your actuaries already know how

Excel formulas, factor tables, and calculation structures your team uses today. No retraining. No Python courses.

Never lose another version

Every model change is persisted forever. On-level any historical exposure to any rate version.

Enterprise-grade security

SOC 2 Type II certified. 256-bit encryption, strict access controls, continuous monitoring.

How is this different from HyperExponential?

HX requires Python. We're Excel-native. Your actuaries don't need to become developers. Same capabilities, versioning, API generation, governance, but using the tool they already know. And we're significantly cheaper.

Can we import our existing rating models?

Yes. Upload your Excel raters directly. The system parses formulas, identifies factor tables, and creates a versioned model. Your existing logic is preserved exactly.

What about complex rating algorithms with custom logic?

Excel formulas handle 95% of rating logic. For the edge cases (custom credibility calculations, proprietary curves), we support formula extensions that your actuaries can define without writing code.

How do trauma studies work?

Upload your in-force policy list with their rating characteristics. Select the proposed model version. The system rates every policy at both old and new rates, showing you the distribution of changes sorted by impact.

What integrations do you support?

REST API for any system. Native connectors for Kalepa, Guidewire, Origami Risk, and Duck Creek. Microsoft 365 (SharePoint and Teams) for document ingestion and notifications.

How does role separation work for SOX?

Three environments: dev (actuaries build), test (QA validates), prod (underwriters use). Different roles have different access. Actuaries can't push directly to prod. Full audit trail of who promoted what and when.

Trauma Studies

Run your entire in-force book through proposed rates before filing. See the distribution of changes. Know who you'll lose.

Staleness Alerts

"Your territory factors haven't been updated in 10 years." AI monitors factor freshness and nudges actuaries to review.

On-Leveling Engine

In 2050, bring 2025 rates to current level. Every version persisted. No more behemoth Excel machinery.

Instant API

Save your Excel model. API is ready. Integrate with Kalepa, Guidewire, or your custom front-end in seconds.
