Lucca Tosto
Most small businesses reach a point where the founder is too busy to keep operations together, but not big enough to hire someone full-time. That's where I come in.
I've spent the last eight years working across operations, finance and technology: the unglamorous machinery that decides whether a business runs smoothly or not. I bring that senior, cross-functional experience to small teams, for exactly as long as they need it.
I work remotely from southern Italy, in English, Portuguese or Italian, whichever puts you at ease.
Where the experience comes from
-
2021 to NowRedefine FinanceFractional Operations Manager · Training & Consulting
As Redefine's head of operations for almost five years, I handled everything from setting the company up in Bahrain and later relocating it to the United Kingdom, to implementing its financial processes (QuickBooks, accounts payable and receivable), rolling out every digital system, and building the HR processes. More recently I implemented the AI systems, starting with ChatGPT, then Perplexity and now Claude. It's a long-standing relationship, still active today on a two-day-a-week retainer.

2021 to 2022Arazul CapitalBanker · Wealth Management
Arazul is a boutique financial services firm in São Paulo, with over R$2 billion in assets under management across credit, corporate finance, asset and wealth management, and trading, and associates in China and the USA. I looked after clients directly, designing personalised portfolios and wealth management solutions with integrity always at the forefront, and built relationships strong enough that many of those clients are friends to this day.

2020WalkeCo-Founder · Fintech
Walke was my first time owning a business: a forward-looking fintech I founded with fellow computer engineering and business administration students. The idea was to make investment advice more affordable, a platform connecting independent advisors to people willing to pay fixed fees, where everyone could also share portfolios and ideas like a social network. I managed and optimised the MVP development alongside the CTO and CEO, leading a team of four developers. We raised outside investment and were paying the whole team, but eventually wound the company down when further funding dried up, since we were all still at university. Still, it was a formative first taste of building something from nothing.

2020 to 2024BRASFICo-Founder · Research Alliance
I was invited to help build BRASFI by Viviane Torinelli, PhD, a risk manager at the Central Bank of Brazil and, at the time, a PhD student, who has since become a long-standing friend. The Brazilian Research Alliance for Sustainable Finance and Investments was inspired by GRASFI, its global research counterpart, and we built it from nothing: I ran the first webinar, led the early social media, then moved onto the admin side. As funding and annual membership fees came in, I became head of finance, formally establishing the association in Brazil, managing expenses, forecasting and reporting back to the members. It has since grown across 15 Brazilian states and 10 countries.

2018Family businessIntern · Restaurant
My family has been in the restaurant business in Brazil for over half a century, at one point across seven states, including Brasília, São Paulo, Salvador and Recife. It's where I learned the basics of owning and running a business: the finance side, and people management, which can quietly make or break a business.
Not a specialist in one thing.
A generalist who's done them
Breadth across functions
Operations, finance, technology and AI under one roof, so the seams between them stop being your problem.
Done-the-work credibility
I've built and run these things myself, on the field, not just advised them from a slide deck.
Multilingual
Fluent in English, Portuguese and Italian, useful more often than founders expect.
Lean by design
A base in southern Italy means senior help stays within financial reach for a small team, without lowering the quality of my services.
How I work with you
Trustworthy & transparent
You'll always know what I'm doing, why, and what it costs. No black boxes, no padded invoices.
Loyal & committed
I take on few clients and stay close to each. Your business gets attention, not a queue position.
Adaptive
Every business is different. I shape the work around how yours actually runs, not a fixed template.
