About OntaBuild

We’re building an AI‑first platform that delivers predictive certainty— forecasting cost, schedule, and risk before a shovel hits the ground.

Why OntaBuild

Forecastable outcomes

Evidence‑based cost & time windows

Explainable AI

Drivers, priors, and confidence

Aligned incentives

Contracts & workflows that match forecasts

Continuous learning

Every project improves the next

Mission

To replace guesswork in construction with explainable, probabilistic forecasts and data‑defined workflows that align Owners, GCs, Designers, and Subcontractors.

Predictive Certainty

Reference Class Forecasting + causal features produce cost & time windows with confidence bands.

Operational Control

Control Tower orchestrates scope, logistics, contracts, and constraints across teams.

Continuous Learning

Every project feeds the models; provenance, drift, and feedback are tracked by design.

Origin Story

OntaBuild was founded by a builder, a scientist and a software developer who saw the same pattern again and again: budgets and schedules set by optimism and convention rather than evidence. We started with an epistemic question—why does construction fail in the face of innovation and intellectual talent?—and built a stack that turns knowledge structures into delivery systems.

  • 20+ years of vertical construction experience embedded into the model design.
  • Research‑backed approach: reference classes, unpacking, and bias mitigation.
  • Platform services that meet teams where they work—field to boardroom.

Timeline

  • Year 0

    Research

    Studied failure patterns; formalized domain ontology.

  • Years 1+2

    Prototype

    Reference classes + pilot datasets; first accuracy wins.

  • Years 3+4

    Platform

    Control Tower, Data Fabric, and assurance features.

  • Next

    Scale

    Portfolio learning across owners, GCs, and public sector.

Operating Principles

01

Epistemology → Ontology

Define knowledge first. Formalize the domain. Then automate delivery with agents.

02

Explainability

Show drivers, priors, and confidence. Decisions should be auditable and defensible.

03

Alignment by Design

Incentives, contracts, and data access designed to align all stakeholders.

04

Human‑in‑the‑Loop

AI accelerates expertise; it doesn’t replace it. We keep the practitioner in control.

05

Security & Governance

Role‑based access, provenance tracking, and compliance for enterprise & DoD.

06

Outcomes over Outputs

We measure certainty windows, variance reduction, and portfolio‑level learning.

Method

From Knowledge to Control

  1. 1

    Unpack

    Structure drawings, narratives, and history; unify taxonomies for cost & time.

  2. 2

    Model

    Build reference classes, causal features, and priors for asset types.

  3. 3

    Forecast

    Generate distributions; expose drivers and assumptions.

  4. 4

    Decide

    Operationalize into contracts, procurement windows, and logistics strategies.

  5. 5

    Learn

    Close loop with actuals; detect drift; improve models and playbooks.

Platform Stack

  • Forecasting Engine Probabilistic cost & schedule with confidence bands.
  • Control Tower Orchestrate scope, risk, and logistics across teams.
  • Data Fabric Ingest, normalize, govern; maintain provenance and lineage.
  • Assurance Security, auditability, explainability for enterprise & DoD.
