Federico Volonteri, Fractional Product & Design Lead. AI-native builder for fintech and complex B2B products.

I help fintechs and B2B SaaS turn complex problems into simple, scalable products, from strategy and discovery to UX, prototyping and delivery.

8+ years building and scaling products across embedded lending, card issuing, business banking and FX at Defacto, Checkout.com, Qonto and Kantox, later acquired by BNP Paribas.

Now available as a Fractional Product Lead, parachuting into companies that need deep expertise and immediate impact, without the full-time commitment.

About

8 years building product at leading fintech companies, across the full spectrum: from early-stage startups (Defacto) to hypergrowth scaleups (Qonto, Checkout.com) to an FX platform acquired by BNP Paribas (Kantox).

Today I take on fractional product leadership for companies that need a senior IC or strategic lead, and I build AI-native products on the side to stay close to the craft.

Born in Italy, raised in Paris. Started my career as a laser physicist in the San Francisco Bay Area before transitioning into product. Lived in San Francisco, Barcelona, and Paris. I work in English, French, and Italian.

How I can help

Fractional Product & Design Leadership

Ongoing, embedded. You need a senior product leader for an extended period, not a single deliverable: continuous leadership, setting priorities, making the daily calls, designing key flows as they come up, growing the team. Typically 2 to 4 days/week, 3 to 9 months.

Product & Team Structuring

A defined, bounded fix. Engineering has scaled faster than product, roles are unclear, there's no roadmap process, or you're hiring your first PM. In a few weeks I audit how product actually works, define roles and process, build the roadmap, and prepare your next hires. I leave you with a well oiled machine.

Complex Product Initiatives/Launches

Defined scope, one deliverable, critical KPI to move. You have a problem to solve in mind: a new onboarding flow, a new lending or payments product, a regulated workflow, an API, an internal platform, back office automation. I own it end to end, from strategy to shipped product, on a timeline tied to the launch date.

Let's work together.

Experience

Defacto, Product Lead (2023–2025)

Owned lending and partner products end to end, taking onboarding, web application, and recovery from broken to best in class.

  • Redesigned the self-serve onboarding flow from scratch, improving conversion by 20% and contributing to a doubling of the customer base within 6 months alongside go-to-market efforts
  • Rebuilt the core direct lending application end-to-end, halving support ticket volume and increasing customer satisfaction by 30 points while supporting a doubling of the customer base
  • Owned the direct lending roadmap, driving a 20% increase in activation among lending customers
  • On Defacto Connect, delivered a full partner-facing product, reducing partner support requests by 70% and meaningfully improving indirect user satisfaction. Live with partners including Qonto, Malt, Pennylane, and Leano
  • Automated most of recollection operations end-to-end (email sequences, legal procedures, AI calling agents), improving recovery rates from 35% to 50% in 6 months while keeping the team at 1.5 FTE
  • Shipped Pulse, Defacto's first product beyond lending, a company scoring tool based on public data, delivered to 20 beta customers to help them assess counterparty risk before engaging with clients or suppliers
  • Structured the product org: hired the design function, organized engineering (~20 engineers) into squads, and co-owned the company-wide roadmap with the founders

Checkout.com, Senior Product Manager, Issuing (2020–2023)

One of the first product hires on a new business line, owning card issuing APIs, the client-facing dashboard & back-office from zero to general availability.

  • One of the first PMs on Issuing, Checkout.com's first product initiative beyond acquiring, helping build the business line from scratch. Issuing has since reached general availability and become a core product offering.
  • Led the Card Management squad (~5 engineers): designed and shipped the full suite of card creation, management, and spend control API endpoints, webhooks, and developer documentation
  • Led a cross-functional build vs. buy analysis on the risk engine, coordinating across product, engineering, legal, and compliance
  • Led the Experience team (5–6 engineers, 1 designer): shipped the client-facing issuing dashboard and built internal tooling for BIN management and client configuration
  • Standardized product discovery practices and product review processes across the issuing teams
  • Onboarded and supported Jow as the first live beta client on the issuing platform
  • Contributed to the Booking.com RFP process, scoping product requirements for one of the largest potential issuing clients in the pipeline

Qonto, Product Manager (2019–2020)

Led a high-stakes migration for 45,000 active customers with zero acceptable margin for customer-facing failure.

  • Led the full migration of Qonto's 45,000 active customers from banking partner Treezor to an in-house banking infrastructure, a 12-months program spanning product, engineering, ops, design, and growth
  • The core challenge: migration required customers to change their IBAN, cards, and entire banking setup. Result: 98% of customers made at least one transaction on the new platform post-migration
  • Built fine-grained customer segmentation to personalize every touchpoint throughout the migration
  • Shipped weekly production deployments across 9 months: in-app migration flows, card reordering, automated account transfers, and back-end automation of regulatory checks

Kantox, Product Manager (2017–2019)

FX automation platform. Helped reshape the product from brokerage to software, a repositioning that preceded acquisition by BNP Paribas.

  • Led a full platform redesign to reposition Kantox from a brokerage tool to a modern SaaS FX management application, hired the company's first designers and owned the end-to-end product overhaul
  • Structured and launched Currency Accounts, a 0→1 initiative in partnership with Citi Bank enabling Kantox customers to hold and manage money in 20+ currencies
  • Helped structure the Citi partnership from the ground up, product scoping, integration requirements, and cross-company alignment

Building: Beyond consulting, shipping AI-native products.

AI operating system for small jewelers

It all started with a quoting tool. I ended up building an AI operating system for jewelers. I initially built JewelQuote, a quotation tool for high-end jewelers doing bespoke, but as I iterated, users kept asking for one place to run their business. Built for jewelers with 1–15 people. Value from day one. AI does the work, you take the actions.

Surfwise: Next-generation surf forecasting.

Built solo from concept to live product. Surfwise is a mobile-first product designed to simplify a core decision for surfers: when and where to surf. Instead of exposing users to raw forecast data (swell, wind, tide), Surfwise translates it into clear, actionable guidance. The product is intentionally focused: it is not a data platform or social network, but a decision engine.

Surfwise currently covers France, Morocco, and Portugal. Current traction: ~30 weekly active users. Built using an AI-native development workflow with Replit and Cursor. AI systems include a Localization Agent and a Spot Ingestion Agent creating a scalable, semi-automated content pipeline.

JewelQuote: Configure-Price-Quote tool for jewelers.

A niche with real purchasing complexity. JewelQuote is a workflow product designed for jewelry houses and workshops to structure and streamline the creation of bespoke and semi-bespoke quotes. Core flow: select or define a model → input key parameters → review and adjust internal costs → define final pricing → generate a client-ready quote document → convert accepted quotes into invoices. Currently deployed as a single-tenant production pilot with one jewelry house, generating real quotes for real clients.
