Who They Work With

Our Take
The best-documented AI portfolio on this page, and the detail is where the value is. For the manufacturer Aralab, an accounts-payable agent reads any supplier PDF with Claude while deterministic code independently recalculates every line total, unit price and tax figure against the matched purchase order: the model proposes, the validation engine verifies. It shipped in six weeks with one engineer, handles more than 2,000 invoices a month, and moved three finance people off transcription.
The operational choices are published too. LangFuse traces every model call with prompt versions and cost per invoice visible in real time, and the review dashboard sorts each document into automated, partially matched or flagged so attention goes only where the model was uncertain.
Two more agent systems run in production: a compliance platform for a European regulatory-technology startup, cutting time per customer inquiry 75 percent and live at three of the top ten European cosmetic brands, and four chained agents for PepTalk over 3,000 speaker profiles indexed as vectors. The PepTalk write-up states plainly that no measured figure for volume, turnaround or conversion has been published.
Best for teams buying an agent system that has to be auditable and cheap to run, from engineers who work inside your stack and hand it back.
Key strengths
- The hybrid pattern is published, not implied: the language model interprets and deterministic code independently recalculates every figure against the purchase order
- Observability ships with the system—LangFuse traces every call with prompt versions and per-invoice cost visible in real time, so the workflow cannot get quietly expensive
- Models sit behind a provider abstraction and were swapped twice on one engagement without the product changing shape
Good to know
- The largest engagement, the regulatory compliance platform, is anonymized—ask for a speakable reference at one of the brands running it
- The PepTalk system publishes no measured outcome by the agency's own admission; ask what the volume and turnaround figures are now
- No headcount is published against a decade of trading—ask how many engineers would be forward-deployed on your build and for how long
