Luciana Reznik Keeps Choosing the Hard Part

The second time Luciana Reznik started a company, she already knew what an ending looked like. Wolox, the software firm she had begun with university friends in Argentina, had grown across Latin America and the United States. She had occupied nearly every useful seat: programmer, process builder, innovation lead, chief executive, growth executive. In January 2021, Accenture acquired the business. The student venture had become an institution large enough for another institution to buy.

An acquisition is a lovely noun. It sounds finished. For a founder whose company has also been her first job, education and adult identity, the verb that follows is less obvious. Reznik stayed for a time, leading work for Accenture's West market and learning the manners of corporate America. The experience gave her room to think. It also clarified the thing she missed: building.

So she returned to the beginning. Not an innocent beginning, exactly. Experience does not restore the factory settings. It lets a founder recognize the butterflies and keep the meeting on schedule.

Reznik studied software engineering at the Instituto Tecnológico de Buenos Aires. Wolox began while she was still a student, created with a group of friends who wanted to build digital products from Argentina for the world. She did not arrive with a polished theory of management. She arrived with technical training, leadership experiences and a willingness to learn in public.

That learning became the job. She wrote software, worked on process and quality, led innovation and then served as CEO. During her chief executive years, Wolox grew from roughly 50 people to 350 and expanded from one country to five. Each jump made the previous operating system obsolete. Roles had to change. Responsibilities had to move. A process that felt sophisticated at 50 people could become adorable at 350.

She described her preferred leadership as horizontal: build balanced teams, give people room to work where they are strongest, keep the conversations open, and remain available for the difficult decisions. The last clause matters. Horizontal leadership without an owner can turn a calendar into a swamp.

Her habits were deliberately porous. Customer calls sat beside strategy work. Mentors sat beside people she mentored. Books and podcasts arrived at a pace of roughly one every two weeks. Away from work, she played tennis, studied music, and sought out cultural and social projects. Curiosity was not framed as decoration. It was part of the machinery.

In 2018, Forbes Argentina included her in its 30 Under 30 recognition. In 2019, Endeavor selected Reznik and Wolox co-founder Agustina Fainguersch as Endeavor Entrepreneurs. Accolades offered a public shorthand. The harder private work remained organizational: how to keep a company recognizably itself while its head count, customers and geography changed underneath it.

After Accenture, Reznik gave the next choice time. She spent about four months studying fields that interested her. Climate change was on the list. So was biotech. Crypto and blockchain formed the third area. Then she made a decision that says more about her founder philosophy than any market map: she chose whom she wanted to build with before the final idea was settled.

Nicolás Magni and Guido Marucci Blas had been university peers and fellow Wolox builders. By the time the three started Cedalio in 2022, their working relationship was measured in years, not coffee chats. Trust was already a tested asset. They paired it with an unusually explicit decision system: 12 areas of responsibility, each with a founder who had the final call after discussion and debate.

The first version of Cedalio helped developers store structured data with the auditability and verifiability associated with blockchain systems. Reznik argued that useful infrastructure should hide its own complexity. People use email without knowing the communication protocols beneath it; developers should not need a dissertation on blockchain to benefit from it either.

This was not a casual market. It carried research risk, shifting technical assumptions and skeptical capital. Reznik was wonderfully unsentimental about the comfort available: “The word ‘safe’ does not exist in what we are doing.” Customers, not confident adjectives, would prove whether value was present.

Cedalio joined Y Combinator's Summer 2023 batch with six people. Its public description soon began to move. The underlying database and extraction capabilities found a use in sustainability reporting, where utility bills, supplier forms and other scattered records needed to become structured, auditable information. Cedalio presented tools for AI-assisted extraction, consolidation and reporting.

Today the company introduces itself differently again. Cedalio is an AI agent platform for the office of the CFO. It automates procurement, accounts payable and the data flows between invoice intake, three-way matching and payment. Finance teams, in this formulation, should govern the work instead of performing every repetitive step.

A product tour through blockchain, sustainability and accounts payable can look like three startups wearing one trench coat. The more useful reading is in Reznik's distinction between technology and value. She has repeatedly argued for falling in love with the problem, not a particular tool. Cedalio kept following messy, consequential business data until it found a sharper owner and budget.

The destination also carries traces of Wolox. Reznik spent years learning how large organizations buy, how founders validate services, and how an offering must adapt when it crosses borders. On a 2023 podcast, she discussed the founder-led work behind enterprise sales: earning the first meeting, asking for useful feedback, pricing bespoke early work, creating urgency, and eventually transferring customer knowledge to a team. Cedalio now sells into a world she has already observed from several angles.

Reznik's interest in information is not limited to databases. In a 2026 post, she described sales meetings where buyers looked to her male co-founder, Nico, for approval, assuming he held the final word. She chose to treat the slight as an instrument. While attention went elsewhere, she could listen, watch intentions and read the room. When Nico later looked to her for approval, the real decision map became visible.

Her conclusion was brisk: being underestimated can be an advantage, if you use it. There is no claim that bias becomes harmless. There is a founder's habit of converting available information into leverage, even when the circumstances are irritating.

That habit extends to geography. Reznik has lived in the Bay Area since 2018, while Cedalio maintains deep ties to Latin America. In August 2026, she explained the relationship in commercial terms: San Francisco does not replace the Latin American market; it can amplify it. A partnership made in the city can become pipeline across several countries. Place is not a badge. It is distribution.

Reznik's second company does not repeat the first one's product. It repeats a more interesting pattern: gather people whose judgment she trusts, enter a complicated market, learn from customers, assign responsibility, and let the organization change before the old version becomes sacred.

The Wolox exit proves that she can finish a company chapter. Cedalio shows why finishing was never the principal attraction. In an interview after the sale, Reznik said she had understood that she needed to become an entrepreneur again because it was what she liked doing. The aspiration was not simply another transaction. It was a return to purpose through the work itself.

There is a temptation to make a repeat founder's story about superior pattern recognition. Reznik's version is more human. The second beginning still carries insecurity. The world is different, the industry is different, and the stomach still notices. Experience helps her handle the feeling; it does not abolish it.

That may be the part worth keeping. Reinvention is not a dramatic declaration made once. It is a series of ordinary permissions: to study before choosing, to keep old collaborators, to abandon an old pitch, to admit that a customer owns the verdict, and to remain the kind of person who can be surprised by the answer.
