Trust infrastructure for digital platforms under regulatory pressure.
Reproducible ML decisions. Verifiable creator payouts. Auditable ad attribution. Stable watermark detection. One arithmetic substrate, one SHA-256 per artifact, provable compliance across AI Act, DSA, and DMA.
Each POC opens with a scenario a platform team will recognize, walks through what SolvNum changes, and ends with a benchmark number plus a SHA-256 you can re-derive on your own hardware.
The same deterministic arithmetic, evidence-based tooling, and audit-grade research platform show up across AI decisions, ad measurement, creator payouts, content integrity, privacy, and regulatory compliance.
AI Decision Audit
Reproducible ML decision pipelines
The decision layer downstream of any ML model — calibration, policy-rule aggregation, thresholding, decision logging — made bit-identical on every platform. One SHA-256 receipt per decision that any party can independently re-derive. The audit artifact that EU AI Act Article 12 and DSA Article 40 actually ask for.
SolvNum
Ads Measurement
Attribution that advertisers can verify
Shapley-value and Markov-chain attribution on the SolvNum substrate. Bit-identical per-campaign credit across every platform, with a three-sided handshake (advertiser, platform, regulator). Optional deterministic differential-privacy overlay that is itself reproducible. The arithmetic-drift component of the reconciliation problem stops being a reconciliation problem.
SolvNum
Creator Economy
Verifiable creator payouts
A five-stage payout pipeline (engagement rollup, fraud adjustment, eligibility, revenue share, FX + tax) in integer micros. Platform issues a receipt; creator re-derives in their browser; regulator re-derives from the audit artifact. Three parties, zero trust, one SHA-256. The dispute queue becomes a hash check.
SolvNum
Content Integrity
Stable watermark detection across platforms
LLM watermark detectors compute a z-score and threshold to decide “watermark present” or “absent.” Near the threshold, float drift flips the decision. SolvNum makes the detection statistic bit-identical across platforms so the decision is stable on every borderline case.
SolvNum
Privacy-Preserving Measurement
Deterministic differential privacy
Standard DP adds random noise that is not reproducible across platforms. Deterministic DP replaces the random source with a cryptographic DRBG keyed on a committed secret. SolvNum’s proprietary quantization absorbs cross-platform math-library divergence in the noise draw. The DP-protected output is bit-identical and still ε-DP. A genuine research contribution with no clean production implementation elsewhere.
SolvNum
Regulatory Infrastructure
AI Act, DSA, DMA compliance substrate
EU AI Act Article 12 (decision logs), DSA Article 40 (researcher reproducibility), DMA Article 5(9) (advertiser verification) all converge on the requirement that the same input must produce the same output with a reproducible audit trail. SolvNum is the arithmetic substrate that makes this possible across every hardware combination a regulator could audit from.

The platform product line on top of one arithmetic substrate.
Each product brief below opens with a scenario your team will recognize, then walks through what it is, who uses it, why it’s defensible, and how the claims survive review.
Built for teams that have to survive regulatory review.
Read-only reproducibility audit on your pipeline in two weeks. Shadow run alongside your existing stack for one month. Production pilot on one workload. Every option credits in full toward a Year-1 license. Every numerical claim traces back to a test ID, a seed, and a verdict in a live evidence register.
