For Iñaki Zubeldia, founder of Yoseyomo, self-custody is a philosophy he has spent years teaching to his 42K YouTube subscribers. Yoseyomo's first product, a metal vault that protects crypto seed phrases from loss or damage, was built directly on that education work. The company's second product, Inheritans, tackles a question most people never think to ask: what happens to their crypto assets, digital property, patrimonial information and personal legacy content when they are no longer able to manage them.
To accelerate Inheritans' development and scale its B2B model, Iñaki Zubeldia turned to his own community rather than traditional VCs. Using Roundtable, Yoseyomo raised €331K from 60 investors, the majority of them first-time startup investors. The SPV structure allowed Yoseyomo to consolidate 60 individual investors into a single cap table entry, while a convertible note gave the company immediate liquidity before the investment was formally converted into equity.
Key takeaways:
- Inheritans is Yoseyomo's second product: a secure digital platform for organising information, instructions and communications related to crypto assets, digital property, patrimonial assets and personal legacy content. To support its next stage of growth, Iñaki Zubeldia raised €331K from 60 investors in roughly two months.
- Roundtable's platform and the team's fast response times to investor questions helped build trust with a community largely new to angel investing. Around 80 to 90% of Yoseyomo's investors had never invested in a startup before.
- The main appeal of Roundtable was consolidation: one platform to manage communication, KYB/KYC tracking, and investment status for all 60 investors at once.
- Using a convertible note allowed Yoseyomo to access liquidity immediately after investors signed, before the investment was formally converted into equity.
Roundtable: Could you present Yoseyomo to our readers?
Iñaki Zubeldia: Yoseyomo is a crypto vault. It's a piece of metal that makes your seed phrase, which is the password to your crypto wallet, indestructible. We replace vulnerable paper seed phrase backups with a durable metal vault.
We also have a second product, a SaaS platform called Inheritans. It answers the question: what happens to your crypto assets, digital property, patrimonial information and personal legacy content if something happens to you? Roundtable helped us raise funds from our community to support the next stage of its development and growth.
Roundtable: How did you come up with the idea behind both products?
Iñaki Zubeldia: I have a YouTube channel with 42K subscribers where I teach people who don't know anything about crypto how to use it securely, with good risk management. Self-custody means being your own bank in the Web3 world. When I started that channel, I realized people don't have a security culture: we're used to banks providing that security for us as a trusted third party. In Web3, you're your own bank, and with that power comes big responsibility. We built Yoseyomo to help our community practice good self-custody.
The name is inspired by the idea of “your seed, your money”, a play on the crypto phrase “not your keys, not your coins.” It also reflects the brand's Japanese-inspired identity and subtly echoes Satoshi Nakamoto, Bitcoin's pseudonymous creator. Our visual identity is built around a discreet, premium black aesthetic inspired by ninjas, who move silently and keep a low profile. Being your own bank requires strong privacy, personal security and discretion.
After launching that product, we started asking a harder question: what happens to your crypto if you die? If I die, my wife may not know what I own or how to access the information she needs. So we evolved the idea into something broader, encompassing financial and patrimonial information (such as crypto assets, investments, property, valuable collections or startup equity), as well as personal legacy content, including videos, audio messages, family recipes and instructions for loved ones.
Originally, we wanted to give our community the same thing we had gotten from them, a piece of the company, potentially through tokenised ownership or NFTs. But at our stage, that was prohibitively expensive: lawyers, compliance, regulation. Roundtable gave us a much more accessible way to let our community actually own a piece of Yoseyomo.
Roundtable: Taking a step back, how did you discover Roundtable?
Iñaki Zubeldia: Through Aticco Ventures, the VC that invested in our first round. Adrian Escabias from Aticco had spoken to your team and told me some of their portfolio companies were using Roundtable successfully.
He introduced me to someone from your team and I immediately decided that this was the right fit: it was so easy and intuitive. We even did a video for my YouTube channel to explain how the vehicle worked, which helped build trust with my audience.
Roundtable: Did you consider other platforms before choosing Roundtable?
Iñaki Zubeldia: No, I went straight with the recommendation and didn't shop around, because it really felt like the right fit.
Sometimes when I mention Roundtable to other founders, they'll say they've used this or that other platform, but I tell them it's not really the same. Roundtable offered a more complete and founder-friendly solution for our needs.
Roundtable: How was your experience with the platform?
Iñaki Zubeldia: Using Roundtable turned out to be a very good decision. Everything is managed through one platform: investor communications, onboarding, compliance documentation and investment status, and you end up with a single entity on your cap table, which sets the company up much better for future rounds. Working with the Roundtable team was also very easy. My main responsibility was to communicate the opportunity clearly to my community, and they could invest anywhere from €1K to €100K.
In total, we raised €331K from 60 investors. The process was transparent and I could see the status of everyone's KYC at every stage. I was genuinely happy with the experience, and I strongly recommend Roundtable to other founders. Because one of the strongest ways to build a company is to involve the community that already believes in its mission. And Roundtable enabled me to convert that community into investors.
Roundtable: How long did it take from deciding to raise to closing the deal?
Iñaki Zubeldia: We began preparing the round around November 2025 and completed the formal closing process in March 2026. But the actual raise itself took about two months.
Overall, this was a very successful round that met our goals.
Roundtable: Can you tell me more about your experience with the Roundtable team?
Iñaki Zubeldia: The response time was excellent. Whenever an investor had a question or an issue, I would loop in the Roundtable team by email and they would reply very quickly. That responsiveness builds trust, especially for someone who is new to angel investing.
Roundtable: Is your investor community mostly based in Spain, or is it international? Did Roundtable facilitate foreign investments?
Iñaki Zubeldia: Mainly Spain, since that's where my audience is. But we also had investors from Canada, the US, and Mexico. Predominantly Spanish, though, because my YouTube audience is Spanish.
Roundtable made it much easier for those investors to actually participate. Without an SPV structure, direct foreign investment in a Spanish company can involve additional identification, documentation and notarial requirements, which can be disproportionate for investors participating with smaller tickets. Roundtable enabled smaller investors from different countries to take part without facing the full administrative burden associated with investing directly in a Spanish company.
Roundtable: For this funding round, you used a convertible note structure, ending up with a single entity on the cap table instead of 60 separate investors. Can you tell me more about that?
Iñaki Zubeldia: A convertible note is a financing instrument that may convert into equity under predefined conditions. We had already used this mechanism in our first round, and it's very useful: investors sign and transfer the funds, giving us immediate liquidity before the investment is formally converted into equity as part of the subsequent capital increase.
Roundtable: What's the typical profile of your investor community?
Iñaki Zubeldia: When we surveyed our investors, we found out that around 80 to 90% had never invested in a company or startup before. Using Roundtable gave them the confidence to invest through what felt like an official, solid platform.
Apart from that, my audience consists primarily of men between the ages of 40 and 60 who often work in tech: we have lots of developers and engineers, but also business owners and professionals. On our cap table, there was a real mix of backgrounds and profiles.
Roundtable: So most of them weren't professional or VC-background investors, and Roundtable made it accessible and easy for them to invest, correct?
Iñaki Zubeldia: Exactly. Managing 60 individual investors, documents and signatures separately would have created significant administrative complexity. With Roundtable, the whole process was much more manageable and straightforward.
It's all on one platform and you move through the steps in order. The only occasional friction came from gathering specific compliance documents, which is normal in a regulated investment process. But even people who don't speak English, or who had never invested before, moved through it smoothly.
Roundtable: Did you get any feedback from investors about their experience?
Iñaki Zubeldia: Overall the feedback was very positive. Some investors found the KYC process highly detailed, but they understood that this level of verification is necessary in a regulated investment process. One of my early investors is actually a VC and put in just €1K specifically to test out investing through Roundtable. I haven't followed up with them yet on how that went, but I will.
Roundtable: What's next for Yoseyomo now that this round has closed?
Iñaki Zubeldia: We've applied for an ENISA loan, which is a Spanish government financing program, to build on this round's momentum. With that funding we're building Inheritans' B2B model: the same software, but tailored for insurance companies, private banks, family offices, and lawyers. We're developing a white-label B2B solution, because going B2B2C lets us scale faster than B2C, which requires far more one-by-one sales and investments in paid media.
We're already in conversations with major companies in Spain and Mexico, and interest has been strong. Once we land our first B2B customer, we expect that to unlock the rest: a successful first deployment can significantly accelerate adoption among comparable organisations.
This kind of service is increasingly necessary. Today people hold crypto, gold collections, startup equity, homes, and vehicles; all those assets are often spread across multiple countries and are often digital. A traditional will remains essential, but it is not designed to provide a continuously updated inventory of digital and patrimonial assets, nor is it designed to manage the delivery of personal instructions, documents, videos or audio messages. Inheritans complements the legal will by providing a secure and continuously updated inventory of assets, information and instructions.
We are adding a secure digital layer to an area that has traditionally relied on static legal documents and fragmented personal records, making legacy planning more structured, accessible and adaptable to modern assets.
Roundtable: That's fascinating. Last question, would you use Roundtable again for future rounds?
Iñaki Zubeldia: If we raise again from our community, I'd absolutely use Roundtable again. For a larger institutional round led directly by a VC, the structure would naturally be different, but if we need an SPV to involve our community or other angel investors, then yes, without any doubt.
