Selected work.

Ampivo Green

Agri-commerce · India

Provingmark runs delivery on the farmer app and the backend behind it.

Ampivo Green puts farmers at the centre of low-carbon agriculture in India.

Agri Kisan Setu is its farmer-facing Android product: mandi price lookup from the Government of India open-data set, localised weather, scheme listings and a crop register, with tutorial and scheme content read aloud for farmers who cannot read it.

Provingmark leads product engineering, releases and the operating roadmap.

Live on Google Play in twelve Indian languages.

Emerald Healthcare

Medical travel · India

Provingmark designed the consent and record-release model before any product code.

Emerald Healthcare arranges planned treatment at Indian hospitals for patients who are abroad while they decide.

A medical record crossing a border is the whole risk in that business, so the engagement began with the consent model, the record-release path and the Indian statutory surface mapped — then the site, then the platform behind it.

Every capability fails closed until it is complete.

emeraldhealthcare.info is live, with the platform in development behind it.

EMVO

Enterprise AI · founder's office

Provingmark worked across the founder's office: positioning, site, collateral and the investor deck.

EMVO is an enterprise AI company. Provingmark worked directly with its founder across the founder's office: product positioning and narrative, the website, the collateral set, the investor pitch deck and the investment strategy behind it.

The positioning line written in that engagement still runs on emvo.ai.

Truffles

Cross-border payments · Singapore

Cross-border payments, with invoices that prove settlement without exposing the parties.

A cross-border payments company in Singapore, founded and run by Provingmark's founder: multi-currency collection accounts, SWIFT payouts and FX for small international businesses, delivered through a licensed Major Payment Institution partner and wrapped in an institutional KYB and AML onboarding stack.

Its differentiator was privacy-preserving invoicing — invoices minted as ERC-721 tokens with encrypted fields and Merkle-proof settlement receipts, so a counterparty could verify an invoice was paid without seeing who paid whom. The ledger and reconciliation discipline behind our payment reconciliation work comes from here.

Selected for Outlier Ventures' first Base Camp cohort.

Neleus

Trading infrastructure

Memory and market signal for agents that trade, with refusals between the model and the order.

A Rust trading stack, co-founded by Provingmark's founder, that puts processed signal and persistent memory in front of autonomous agents trading live venues. Its architecture is the reference for our AI agent development work.

Four independent refusals sit between a model and a live order.
