Area of expertise

AI under regulatory constraints
The pressure to do something with AI arrives before anyone has decided whether it fits, and for a business taking recurring payments in a regulated market the risk runs both ways: paralysis, or a rushed bet that crosses a line the market's excitement won't move.

Platform migration and scaling
A business has to re-platform, front end, back end, or both, while subscriptions, billing and renewals keep running. It gets treated as an engineering cutover, but the part that bleeds money is the revenue layer that has to survive the move.
more →
Regulatory compliance
A payment or compliance requirement lands (an SCA deadline, a PSD2 reading, a market-entry rule) and product, legal and engineering each work to a different definition of compliant. The deadline doesn't move, so the risk is to over-build or miss the line and loses revenue to failed authentications.

Subscription optimization
Trial-to-paid or retention flattens, and sometimes it's easy to answer with untested changes: an onboarding tweak, a paywall edit, a reminder email. But what's really needed is an experimentation framework inspired by the goals the company wants to achieve.

Ways to work together

Recommended start

Diagnostics

1 week fixed

A focused week on what's breaking, where, and in what order to fix it, with final written assessment and a prioritised plan.

  • Rapid discovery of revenue leaks and process bottlenecks
  • Stakeholder interviews and data analysis
  • Prioritised action plan with clear next steps
  • Written diagnostic report with recommendations
  • Quick wins identified for immediate impact
bugdiscoveryGTM

Project

1-3 month depending on scope

A scoped piece of work with a defined outcome: a migration that has to hold revenue, a trial-to-paid or renewal problem traced and fixed, or an SCA/PSD2 programme shaped into something the team can build. It ends with a working solution the team can carry.

  • Clear project scoping and success metrics definition
  • Hands-on delivery alongside your team
  • Handover of documentation for continuity
  • Roadblock identification and mitigation
  • Working solution shipped to production
bugdiscoveryGTM

Embedded

3-12+ month quoted

Ongoing senior ownership, around two days a week, for a company that needs someone holding the payment and subscription layer through a period of change, but isn't ready to hire a full-time lead for it. It's built to hand back: the aim is a team that owns it without me.

  • Onsite, hybrid, or remote
  • Senior product leadership—strategic and operational
  • Decision making and process ownership
  • Team support: coaching, hiring support, mentoring
  • Stakeholder engagement

Advisory

1 day day rate

Day-rate advisory for bounded questions (an authentication or renewal decision, a payment-provider evaluation, a regulatory reading) and a faster emergency rate when an SCA or payments deadline is close and the answer can't wait.
Package highlights:

  • Engagements from a few hours to a few days a week
  • Advice on strategy, UX, hiring, partnerships, and compliance
  • On-demand calls for critical issues
  • Remote only
  • Assessment of urgent risks and mitigation options

About

Maria Grazia Chetta

I have addressed complex product challenges, including building platforms from the ground up, migrating legacy systems under regulatory pressure, and managing compliance programmes across multiple markets. These initiatives have delivered measurable results, such as reducing operational costs, accelerating go-to-market, and mitigating compliance risk. When renewals decline, trial-to-paid conversions drop, or market-specific authentication issues arise, growth is at risk. The underlying causes often include market-specific authentication requirements (such as SCA and PSD2), customer journey flaws, or inadequate cancellation logic. These issues can hinder growth until they are thoroughly analysed and resolved.

My goal is to deliver solutions that provide lasting value by using framework-based methods, standards, and documentation. This approach ensures effectiveness continues after my involvement.
My expertise lies in solving complex, ill-defined problems that require clarity and structure, rather than focusing on a specific industry. My approach is well-suited for leadership teams and organisations undergoing transformation, scaling, or regulatory change, especially in complex, highly regulated, or technology-intensive sectors.

I have a combined STEM background in Statistics and Life Sciences, and completed a capstone project in applied machine learning.
