The forecaster inside your AI agent.

LLMs reason over text. They can't predict what happens next from your client's data, that has to be modeled. Phaeth Cortex is the forecasting layer you embed in your agent: it predicts demand, revenue, churn and outcomes, runs what-if simulations, and is called over a stateless API & SDK. We own the modeling; you ship the feature, your brand, your margin.

Predict, simulate, then monitor: one loop your agent runs.

Cortex turns your client's data into a twin your agent can query over the API: simulate a what-if (blue), act on the forecast (jade), monitor outcomes and drift (amber), then learn and predict again. Entities, actions and roles: the same model behind every job.

01
Entity Twin

The blueprint: model the things that matter

Customers, facilities, assets, tickets, or populations become queryable twins that collect data and can be classified, segmented, and predicted against: the risk-free sandbox for every what-if.

baseline locked · ready to simulate
02
Action Twin

The execution: model the changes you ship

Email campaigns, surveys, product features, and process changes become testable actions you can replay and compare in simulation, then push live when the numbers hold.

03
Role Twin

The pulse: model the goals and decisions

A role twin, such as a hotel manager or support lead, watches every entity and action twin, alerts on drift, recommends the response, and feeds real outcomes back into the next simulation.

The dashboard told you what happened.
The agent reads your docs.
The twin tells you what's about to happen.

Every business question used to end in a chart. Then in a chatbot. Now it ends in a prediction. Phaeth is the tool that gets you there in the same afternoon: a twin trained on your data, not another agent reasoning over text.

Dashboard

  • Tells you what already happened
  • Static: read-only
  • Built once by IT, hard to change
  • Data has to travel to the cloud
  • You stare at it and decide alone

Twin

  • Tells you what's about to happen
  • Live: you can talk to it
  • Built on demand, in plain language
  • Runs where your data lives
  • Alerts you the moment it matters

Phaeth tells you what to do.


Every role gets a twin. This is one of them.

A Role Twin is any job function: defined by the actions it can take, the metric it owns, and the entities it acts on, whether those entities are customers, accounts, or tickets. The example below is a support lead testing three resolution strategies across a population of synthetic tickets; a pricing manager, a maintenance planner, or a loyalty marketer works exactly the same way. Each Entity Twin is built from your real data, then enriched with signals derived from it.

From your client's data to a forecast: over one API.

Cortex ingests first-party data from any system of record, CRM, ERP, billing, sensor logs, trains and maintains a calibrated model with machine learning, then serves predictions, what-if simulations and drift signals back to your agent over a stateless API. It stays decoupled from delivery, so you're never tied to one vendor. The flow below: records in, Action Vectors out.

The alerts you never got.

Every one of these warnings was sitting in ordinary support data: ticket queues, chat logs, CSAT surveys. Nothing was watching. You found out the way everyone does: after it cost you.

⚠ This alert never fired · churn · found out at renewal
Acme Corp churned in March after three reopened tickets. You found out at renewal.
The warning was there: the same issue reopened three times, CSAT slipping, replies getting slower for three straight weeks. Nobody connected the tickets to the account. Cost: a $48,000 renewal, and they weren't the only one.
With Phaeth: the Role Twin fires this alert weeks before the renewal, with the at-risk accounts ranked by value and the reopen pattern driving each one.
⚠ This alert never fired · SLA breach · failed Saturday 02:10
A VIP ticket sat 14 hours past SLA on a Saturday night. The reopen and breach risk was clear two days earlier.
The breach alarm fired at 02:10, the moment the clock ran out, not the days before when the ticket was clearly heading sideways. Cost: a furious enterprise customer and a service credit, for a ticket that could have been escalated on Thursday.
With Phaeth: the Role Twin reads the same queue and gives you days of warning on the tickets about to breach or reopen, with the escalation to make now.
⚠ This alert never fired · launch · discovered in production
A pricing-page change buried your queue for three days. The macro you shipped to clear it tanked CSAT.
The change was never tested against your own ticket history, it shipped straight to customers. The surge hit, the canned reply went to everyone, and satisfaction cratered. Cost: a week of overtime and a CSAT hole that took a month to climb out of.
With Phaeth: the change runs against your twins first. The ticket surge and the CSAT drop show up in simulation, where they cost nothing.

Your only test environment is production.

Every campaign, price change, and process tweak debuts on real customers, because until now there was nowhere else to rehearse it. Phaeth gives you that somewhere: a population simulation over your entity twins, built from your own history, where any change can fail safely before it goes live.

01
TEST

Replay changes against what already happened

Validate a new email campaign, survey, support process, or product feature against historical outcomes before customers experience it.

02
SIMULATE

Predict the likely effect with machine learning

Replay the action across the whole twin population, every customer, account, or ticket, and read a distribution of outcomes with confidence levels, not a guess.

03
IMPROVE

Turn insight into autonomous improvement

Once live, the twin keeps watching outcomes, alerts when performance changes, recommends the next-best action, and improves the loop over time.

LLM synthetic personas

  • An LLM improvising how a customer might sound
  • Trained on the internet, not your business
  • Gives you prose, not probabilities
  • Different answer every run
  • No way to verify it against reality

Phaeth population simulation

  • Entity twins built from your real customers, accounts, and tickets
  • The actual statistical distribution of your population
  • Gives you numbers with confidence levels
  • Deterministic: same recipe, same result
  • Backtested against your held-out history

Anyone can ask an LLM to play your customer.
Phaeth replays the action against the population that actually behaves like them.


Not another agent.
A forecaster.

Every agent reasons over text you already wrote. None of them train a predictive model of the client's business. Cortex is the forecaster you drop inside your agent, so it stops guessing and starts predicting.

Agent platforms

  • Reason over docs, tickets, and tools
  • Answer "what does my data say?"
  • Output: chat replies & workflow actions
  • Built on an LLM + integrations
  • Tests ideas on LLM personas that sound like customers
  • No model of what happens next

Your agent + Cortex

  • Predicts from your own data
  • Answers "what happens if we change this?" before launch
  • Output: test → simulation → recommendation → action
  • Creates Entity, Action, and Role Twins in plain language
  • Tests actions on a population of your real entity twins
  • Gets sharper with every outcome it sees

Other platforms gave your agent a co-pilot.
Cortex gives it a forecaster.


Specialised for support.
Open for everything else.

Phaeth works on any prediction problem you can describe. Customer support is the one we lead with: we've shaped the tool to know which signals close a ticket for good, and which ones quietly cost you the account. Bring your own; every new use case our users try makes Phaeth smarter for the next one.

SUPPORT

Resolution & Reopens

First-contact resolution, reopen risk, escalation. Built around queue age, channel, sentiment, and prior contacts: the signals that decide whether a ticket closes for good.

SUCCESS

Churn & Renewal

Account health and renewal risk read from support behaviour. Reopen patterns, response times, and CSAT trends: the early warnings a healthy ARR number hides.

OPERATIONS

Queue & Staffing

Ticket volume, surge, and handle-time forecasting. Channel-mix, seasonality, and launch-aware: so the queue is staffed before the spike, not after the backlog.
