Gigaton

If procurement requires published, audit-ready security and compliance proof (SOC 2 Type II / ISO 27001 certificates, subprocessor lists, detailed security whitepapers)

• The vendor does not publish these details prominently; organisations that require these documents during initial procurement may find incumbent vendors easier to evaluate.

If the plant strategy is to work exclusively with a single automation vendor

• If an incumbent vendor (ABB/FLS/Rockwell/Honeywell) already manages the DCS/APC stack and procurement prefers a single accountable supplier for OT lifecycle and support, upgrading the incumbent APC may present lower integration risk.

If the organisation will not accept autonomy risk

• Automated closed-loop control in high-temperature continuous processes can present governance and safety challenges. If an organisation will only accept decision-support (recommendations), analytics-only vendors or advisory configurations of APC may be preferable.

If transparent, independently validated ROI is required prior to purchase

• Much of the vendor’s ROI evidence is vendor-published or reported in industry press. Organisations requiring audited, third-party validated savings should plan for a pilot with strict measurement protocols and clearly defined baselines.

Limitations acknowledged or implied by vendor/public materials

• Data readiness is a gating factor: the vendor markets a data assessment as a precondition for deployment.
• Detailed results and methodologies are often gated behind contact forms, limiting public verification.

Common limitations in continuous-learning control systems (buyer diligence topics)

• Governance of continuous learning
  • How model updates are validated prior to deployment
  • Whether a human-in-the-loop approval step exists and how rollback mechanisms operate
• Safety and process constraints
  • Enforcement of hard process limits independent of AI policy
  • Procedures for sensor failure, analyzer outage, or abnormal operating modes
• OT cybersecurity
  • Cloud connectivity architecture, data egress controls, and incident response procedures

Vendor-stated differentiators (to be validated in pilots)

• Use of continuously-updating machine learning models that the vendor describes as "self-learning," intended to reduce the need for periodic manual retuning.
• Features described by the vendor as providing operator-facing explanations for control actions.
• Predictive modelling and digital twin-style simulation capabilities for scenario analysis prior to live changes.
• Reported short time-to-initial-deployment in showcased cases (for example, a cited 8-week period to reach a live state in one case study).

What is independently verifiable

• Corporate rebranding (from Carbon Re to Gigaton) and company incorporation details are verifiable via corporate registry records.
• The Series A funding round size and date are corroborated by multiple public announcements.
• Contract announcements in industry press provide third-party confirmation of commercial engagements.

Where competitors may have advantages

• Incumbent automation vendors typically provide mature security/compliance documentation, established long-term support organisations, and wide integration experience with DCS and plant safety systems.

• A small reduction in the vendor's reported fuel cost index driven by a modest decrease in specific heat consumption
• A notable reduction in C3S variability
• A small reduction in fuel-derived carbon emissions
• A short deployment period to go live (on the order of weeks)

• The plant operates with a high thermal substitution rate using refuse-derived fuels and sought to extend capabilities of its existing APC with AI-based models.

• Detailed baselines, statistical analysis, test design, and evidence of result durability across multiple operating regimes are not publicly available. Full results presented by the vendor are gated behind vendor access controls, limiting independent verification.
• It is unclear whether the reported savings are net of software and services costs.
