Short answer: they solve overlapping problems with different depth. Certificial verifies a certificate is on file at the moment of submission (timestamp compliance). Syntheka governs the action of paying a subcontractor and gates it on angle compliance — endorsement, written contract, and coverage form. Many teams will use both. Here is the full comparison, including where Certificial wins.
| Dimension | Certificial | Syntheka |
|---|---|---|
| Core question | “Is a certificate on file right now?” | “Should we release payment to this subcontractor, based on what the prime contract requires and what the policy actually says?” |
| Verification depth | Real-time verification against 25,000+ agencies | Endorsement triplet (endorsement, written contract, coverage form) extracted from the prime contract and checked against each certificate |
| Write-side governance | Alerts and certificates — timestamp compliance | Staged proposals → multi-node approval DAG (segregation of duties) → payment gating → executed with three-way reconciliation |
| Audit trail | Status logs and alert history | Append-only bi-temporal trail with hash chain and causal-ID replay |
| Payment gating | Not in scope | Native: payment applications stay blocked until a qualified approver clears the gaps |
| Multi-entity / multi-GC | Vendor master per client | Entity / project / contract as first-class fields; cross-entity writes require explicit override |
| Self-hosting | SaaS only | Self-hosted or private cloud; data stays in your perimeter |
| Pricing model | Enterprise quote-only | Published tiers: $500 / $2,000 / Enterprise; $1,500 fixed-fee pilot |

If your primary pain is “do we have a certificate on file today,” Certificial's real-time feed against 25,000+ agencies is a strong product. Syntheka's strength is the next layer: gating the action on what the certificate actually says.
Certificial's vendor self-service portal is mature. If you need a certificate intake form that vendors actually use, Certificial has years of design behind theirs.
Certificial covers commercial real estate, retail and franchise, utilities, transportation, manufacturing, and government — broader than Syntheka's seven vertical templates today.
The endorsement triplet (endorsement, written contract, coverage form) is what an auditor will check when an incident lands. A certificate on file today is timestamp compliance. Syntheka checks the angle: is the right endorsement attached, does the written contract require it, does the coverage form respond?
Syntheka's approval DAG can gate the payment application itself, not just send an alert. The payment does not move until a qualified approver clears the exceptions. This is the layer that turns compliance evidence into compliance enforcement.
Syntheka runs in your infrastructure. The certificate, the endorsement, the audit trail — all of it stays inside your perimeter. For projects where the contractor's data sovereignty is a contractual or regulatory requirement, this is the deciding factor.
If you are choosing between Syntheka and Certificial, the most common outcome is: keep Certificial for the agency feed and add Syntheka for the angle-compliance and payment-gating layer. The pilot is built around that outcome.
