I take any problem
from a blank page
to a product people trust.

Software got cheap to make. Judgement did not, and that is what I sell. I earn it through research into the market, the customer, the competition and the business model, turn it into a case the business will back and a plan the engineers can build, then lead the team of engineers and AI agents that ships it.

Ten years in digital assets — tokenised real-world assets, stablecoin rails, DeFi lending, on-chain privacy — have made me deep enough to choose the standards a product stands on, and clear enough to make it simple for the people who use it.

Outside crypto, I bring the same judgement to AI as a forward-deployed AI product manager: inside a business, I find the workflows where agents save real time and money, and design how they work alongside the people who approve their output.

Analytics that take a business question to an answer.

Mu Sigma built an enterprise analytics product for Fortune 500 clients that automated the path from problem to insight and cut the time to an answer by over 90%. My product journey started on its team, where I ran the cleaning, modelling and insight work that fed it.

Enterprise productData and insights

What I can do for you

Five kinds of work you can bring me in for. I have done all of them end to end, on my own products, inside listed companies and as an outside consultant. Hire me for one and you get the other four as well.

Zero-to-one product leadership

I will find the problem worth solving and ship a first version your users can test.

  • Turn your thesis into a scoped first product, a roadmap and one north-star metric
  • Run the discovery and place small bets, so we learn before we build
  • Set the commercial model and unit economics before a token or price exists
  • Design the first screens myself and hand engineering a spec they can build from

Forward-deployed AI product management

I will embed with your customer or your enterprise, find the workflow where AI pays, and take agents to production.

  • Map the customer’s real workflows on site and pick where an agent belongs
  • Write the business case and win approval, from the first workshop to the executive sponsor
  • Set the guardrails: approval gates, LLM evals, human-in-the-loop sign-off and an audit trail
  • Take the first module through UAT to production, then feed what we learn into your platform

Digital assets, payments and DeFi products

I will own a trading, margin, lending, payments or custody product and explain its risk and compliance setup to a regulator.

  • Define margin, collateral and liquidation rules a trader or an agent can read
  • Choose the rails, from stablecoin settlement to custody, and decide build, buy or partner
  • Design the KYC and onboarding funnel so compliance does not kill conversion
  • Turn DeFi steps into plain banking actions, with the liquidation risk shown on every borrow

Privacy and zero-knowledge products

I will design privacy-preserving compliance: what your product proves, what it hides, and how it stays usable.

  • Specify selective disclosure: which facts an auditor, a regulator or a counterparty sees
  • Pick the proof system and know what proving costs before it hits the roadmap
  • Write the circuit-level spec with your cryptographers: commitments, nullifiers, range proofs
  • Explain the proof to non-cryptographers: your board, your auditor, your users

Capital, partnerships and go-to-market

I will raise the grants and capital, get integrations live, and grow the builders around your product.

  • Write the grant and investor case and run the process to a close
  • Structure integration partnerships and see each one through to launch
  • Define the developer product: API and SDK use cases and the docs builders read
  • Run the hackathons, workshops and community programmes that bring developers to build on your product

Which one is your product missing?

Tell me where it is stuck and I will say what I would do first.

My thesis

By 2030 I expect regulated money to settle on-chain, AI agents to spend it within limits their owners set, and zero-knowledge proofs to handle what must be disclosed. I build products where these three meet.

  1. 1Digital assets: regulated money moves on-chain

    Tokenised deposits settle inside the largest banks, tokenised treasuries are past $15 billion, and collateral moves between custodian and exchange around the clock. Banks and asset managers go first on permissioned rails with qualified custody; fintechs arrive through stablecoins under GENIUS, MiCA and Canada’s Stablecoin Act.

  2. 2DeFi: credit against the whole book

    Perp DEXs clear a tenth of crypto perpetual volume, yet on-chain credit is still overcollateralised and siloed by venue. I expect the layer above the venues to win: one margin account, portfolio margin on net exposure, a live risk engine. Funds adopt it first, fintechs embed it over an API, banks follow once collateral is tokenised deposits.

  3. 3AI agents: software gets a spending limit

    Visa, Mastercard and Stripe sit inside the x402 Foundation; agent wallets, MCP tool access and spending policies are live, and ERC-8004 gives an agent an on-chain identity and reputation. The product to build is a policy layer: know-your-agent, per-task limits, allowlists, and a named person signing above a threshold.

  4. 4Privacy: prove it, never publish it

    Institutions will not put their books on public rails without selective disclosure, and the rules are moving that way: the EU identity wallet ships by end-2026 and proof of reserves is becoming table stakes. Viewing keys, privacy pools and range proofs make compliant privacy the default; compliance officers, not cryptographers, decide what is shown.

Where they converge

  • Agents spend under policy

    An agent with an allowance, an allowlist and a session budget, paying over x402 or a card rail for exactly what its owner permitted.

    I framed this: Perflo
  • Credit against net exposure

    A trader, a business or an agent borrows against its whole book in one margin account, under a health factor that no AI prompt can change.

    I build here: Vanna
  • Prove the facts, keep the book private

    A desk proves it is collateralised, eligible or screened with a zero-knowledge proof and a viewing key for the regulator; the book stays private.

    I prototyped this: ShieldLend
  • Agents inside the ERP

    Agents draft the order, the invoice match and the posting; a person confirms each one before it reaches the ERP, and every write is logged.

    I build here: agentic infrastructure for three listed companies

Next: the account where people, businesses and their agents hold tokenised money, borrow against it and prove only what they must. Auri is step one.
