Actuarial Labs introduces Pia
The modeling platform
for insurance pricing.
Pia turns raw policy and claims extracts into filing-ready GLMs and GAMs in minutes. No data-engineering queue, no data-science backlog. Your actuaries stay in charge.

Who does what
The hand‑offs disappear.
A pricing review used to wait on a data engineer, then a data scientist. Pia now does both, and the actuary works on the part that needs judgment.

Data engineering
- Map columns to rolesTarget, exposure and 9 rating factors found
- Join policy and claims filesClaims summed per policy, exposure counted once
- Clean what extracts really look likeSentinels, currency typed as text, Excel dates
- Split and freeze the holdoutHalf of it stays sealed until the champion is chosen

How it works
From raw extract
to filed rate.
Pia does the data engineering and the data science. Your actuaries make the calls and sign the filing.
Step 01
Drop in raw extracts. Pia finds the schema.
Policy, claims and exposure files exactly as your admin system exports them. Pia recognises the target, the exposure and every rating factor from the data itself, reconciles the files and cleans what real extracts look like.
| IDpol | Unique on every row | Identifier |
| ClaimNb | Count, mostly zero | Target |
| Exposure | Fraction of a year | Exposure |
| DrivAge | Integer, 18 to 100 | Rating factor |
| BonusMalus | Integer, 50 to 230 | Rating factor |
| Region | 22 levels | Rating factor |
Step 02
Pia proposes. You approve.
Safe fixes are applied and logged. Anything that changes what the data means is proposed with its evidence and waits for an actuary. Nothing touches the data until you say so.
Step 03
Every model family, ranked on one holdout.
GLMs, shape-constrained GAMs, frequency × severity and a GBM benchmark, tuned and ranked in minutes. You see how much lift is left on the table, and what it costs to file.
Step 04
Relativities you can stand behind.
One-way experience beside every relativity, credibility-weighted where data is thin. Override a level and your reason lands in the audit trail, with your name on it.
Step 05
The filing writes itself.
Actuarial memorandum, exhibits and rate pages, drafted from the model with every number traced to its source. Edit any section; Pia keeps the numbers tied.
Selected relativities are credibility-weighted between indicated experience and current factors, and capped at ±10%. The selected relativity for Territory 08 is 1.180, for an overall indicated change of +6.2%.
Step 06
Reviewed before the regulator does.
Pia reads the filing as the examiner will, against the rules of the jurisdiction it is filed in. Every check shows the rule, its source, and what your filing says.
Built for the people
who sign the filing.
Half the holdout stays sealed until the champion is chosen, so the score you file is the score you earned.
Actual against expected in every decile of risk, not just in total.
Every fit, override and approval: who, when and why, ready for the examiner.
Hosted in Canada, isolated per account, never used to train an AI model.
