Solenne Niedercorn Desouches began her entrepreneurial journey in 2015, stepping boldly away from the structured, familiar world of finance into the unpredictable terrain of entrepreneurship. What looked like a logical transition from banking to business soon revealed itself to be a humbling crash course in everything she thought she knew and everything she didn’t. Today, as the founder of Finscale, Solenne Niedercorn Desouches stands as a testament to what it means to learn by doing, to fall forward, and to build something lasting from lessons earned the hard way.
Solenne Niedercorn Desouches was not new to high-stakes environments. In finance, she managed deals that moved millions. She understood numbers, strategies, negotiations, and the serious weight of decisions. But running a business? That was an entirely different game. The first venture she launched taught her more than any job or degree could have. It stripped away assumptions and demanded that she wear every hat marketer, admin, brand strategist, copywriter, and more. Solenne Niedercorn Desouches quickly learned that technical expertise in one field does not automatically translate into entrepreneurial success.
When she talks about that period, it’s with the clarity of hindsight and the honesty of someone who’s done the work. The first business didn’t fail it educated. It was a proving ground. It was where she discovered that marketing is not a bonus, it’s the lifeline. That building a brand goes far beyond logos. That a brilliant product doesn’t matter if no one hears about it. And that no one teaches you how lonely and complex the journey can be until you live it.
Solenne Niedercorn Desouches doesn’t glorify hustle for its own sake. Her reflection is refreshingly grounded. She speaks about learning to price services, chasing unpaid invoices, crafting persuasive offers, and producing content that builds credibility not as glamorous highlights, but as necessary skills. She faced hard truths: a handshake isn’t a legal agreement, financial emails don’t drive sales, and burnout is what happens when you don’t learn automation fast enough.
By the time she founded Finscale, her second business, Solenne Niedercorn Desouches was not the same person. She had built new muscles. She knew how to navigate legal complexities, how to position her services in a B2B space, and how to make technology work for her instead of against her. Finscale wasn’t just a business; it was a sharper, more resilient reflection of her evolution as a founder.
What makes Solenne Niedercorn Desouches inspiring isn’t the outcome it’s the process she openly shares. She is not trying to sell a success story wrapped in gloss. She’s pointing out the jagged path behind it. The missed contracts. The rewrites. The uncomfortable client calls. The tools she had to teach herself just to survive Zapier, Notion, APIs, CRMs. Every system she now masters came from the necessity of not drowning.
There’s something deeply relatable about how Solenne Niedercorn Desouches tells her story. She doesn’t pretend to have had it all figured out. Instead, she invites others especially those in finance looking to cross into entrepreneurship to consider what they don’t yet know. That invitation isn’t a warning. It’s an opportunity. She’s saying: your experience matters, but you will need to become a student again.
For many, leaving a successful career in banking would be unthinkable. But Solenne Niedercorn Desouches took that leap, and in doing so, discovered a different kind of success one rooted not in titles or numbers, but in growth, grit, and meaningful impact. Through Finscale, she didn’t just launch a venture she created a platform that reflects her belief in sharing real lessons, supporting others in the ecosystem, and evolving alongside her work.
