Silvia Curioni did not leave Silicon Valley because tech failed her. She left because it succeeded—and still left her hungry for something slower, more tactile, and closer to the cultures that raised her. After co-founding three startups, shipping products used by major grocers, and living the late-night code-and-pitch cycle, she started ZIPPERLY at 40: Italian-made leather handbags, Brazilian-crafted jewelry, designed in San Francisco. The brand’s promise is simple and stubborn. Heritage is not a mood board. It is a supply chain.
You spent more than a decade building tech companies. What actually broke the spell?
Burnout, but not the Instagram kind. I was running startups while raising two young children and checking every box that is supposed to mean you have arrived. The work was impressive on paper and empty in the body. On a trip back to Italy, where I had lived for five years earlier in my career, I watched artisans work leather the way my father’s generation treated craft—as identity, not inventory. I realized I had been building systems for other people’s lives and postponing my own. ZIPPERLY was the decision to stop postponing.
Tech founders usually talk about scale. Fashion founders talk about season. How do you hold both?
I still think like an engineer. Small batches, tight feedback loops, no paid ads until the product and the story can carry themselves. But leather does not iterate like software. A full-grain bag from Civitanova Marche is meant to last decades, not a sprint. That tension is the point. Technology taught me how to find customers without shouting. Craft taught me that some things should not be optimized away. We grow ZIPPERLY the way we make the bags: slowly, on purpose.
The brand splits production across Italy and Brazil and design in California. That is a logistical headache. Why insist on it?
Because that is my life. I was born in Brazil to an Italian immigrant father. Italian at home, Portuguese in the street. Later Italy. Then the United States. For years I treated that split as a problem of belonging. Christian Louboutin once said that when we come from different cultures we are not divided, we are multiplied. That line became the brief. Bags in Italy. Jewelry with Brazilian artisans. American restlessness in the design. The Bird of Paradise is the symbol because it grows in both Brazil and California and refuses to be shy about it.
What does “tech plus fashion” look like on a Tuesday?
It looks like me answering customer messages myself, tracking a shipment from the Marche, rewriting a product page, and then going to the workshop photos to check a stitch. It also looks like using every cheap, powerful tool I already knew from startups—email, analytics, a direct relationship with the buyer—so the brand does not have to rent attention. I wrote about growing without paid ads because that constraint forced clarity. If a bag cannot sell on quality and story, more spend will not save it.
You launched in your forties after selling companies. A lot of people treat that as late. Did it feel late?
It felt late for about a week and then it felt accurate. Forty is not a crisis if you treat it as inventory. I already knew how to raise money, miss payroll in my head at 2 a.m., ship a product, and recover from a bad partnership. Fashion was the new language. The old skills translated. I had support—my husband, close friends—and I had enough scar tissue to know that fear is just data. Vera Wang and other women who started later were useful reminders that the calendar is not the board.
Slow fashion is easy to say and expensive to do. How do you keep it from becoming a slogan?
We make fewer pieces. We work with multi-generational workshops. We talk about the leather as full-grain that ages instead of a surface that photographs well once. Some accessories use different materials because not every object needs the same pedigree, and I would rather be honest than pure. The goal is an heirloom, not a drop. If a customer can pass the bag to a daughter and still recognize it, the model worked.
What do you tell other women who want to leave a “serious” industry for a “pretty” one?
That the binary is the trap. Fashion is operations, cash flow, customs, quality control, and taste under constraint. Tech is also taste, whether people admit it. The harder part is identity. You will feel like an impostor in the new room and a deserter in the old one. Do it anyway, in small steps, and keep the parts of yourself that already work. I did not throw away computer science. I used it to build a store that could talk to a woman in another country without a middleman shouting over her.
Where is ZIPPERLY going next?
More wholesale, more cultures in the next collections, and the same refusal to rush. I started a newsletter, The Female Founder, because the private version of this story—mother, wife, immigrant, former engineer—is the part other women keep writing to me about. The bags are the product. The permission to start over without erasing the first career is the other one.
ZIPPERLY will not look like a unicorn deck, and that is the design. Curioni is betting that a woman who has already scaled software can scale meaning the same way: one durable object, one honest origin story, and a customer who recognizes herself in the stitch.
