A lot of solo builders fuse their personal voice and their product company into one undifferentiated thing. The founder's face is the homepage, every post is a soft pitch, every piece of writing is in service of the funnel. It works for some people. I have come to prefer a cleaner setup, where my personal writing and Yonasol each get to do their own job, and reinforce each other where they naturally meet.
So I run two surfaces, on purpose, with different shapes.
- My personal writing is where my point of view on AI and product leadership lives. It is reflective, slower, and not in service of any specific product launch.
- Yonasol is the product company. It is where AI products get built, run, documented, and sold. It is opinionated, focused, and tied directly to what the lab is shipping.
These are not separate lives. They are two parts of the same body of work. The split is about giving each one room to do what it does best.
Why two surfaces
A few honest reasons:
The audiences arrive for different things. Readers who follow my product writing are operators and product leaders looking for sharp ideas about AI, leadership, and how good product work gets done. People who use a Yonasol product are operators trying to solve a specific problem in their week. Sometimes they are the same person. Often they are not. Letting each surface speak in its own register means neither one has to compromise.
The jobs are different. Personal writing earns trust slowly through consistent point of view. A product brand earns trust quickly through a clear promise and a working tool. Mashing them together makes both jobs harder.
The cadences are different. Personal writing is reflective and low frequency. Product work is fast, opinionated, and ships on its own schedule. Trying to run both on one calendar usually means one of them suffers.
It is more fun this way. This is the part that does not get said enough. When the two surfaces are clean, my writing gets to think out loud without it feeling like marketing, and Yonasol gets to ship without every post turning into a referendum on me as a person. Both halves get to be themselves.
What lives on each surface
On my personal writing:
- A point of view on AI, product leadership, and how operators work
- Frameworks, opinions, and field notes from twenty years of building product
- Teardowns of how AI is changing product work and team workflows
- Long-form thinking that is not tied to any specific product launch
- Selective collaborations, conversations, and guest writing
On Yonasol:
- The lab itself, the operating system, and the active bets
- Lab Notes about how the loop runs and what got learned
- Product pages, pricing, onboarding, and customer-facing materials
- Build logs, teardowns, and recipes tied to specific products
- Direct selling, customer conversations, and product launches
The rule of thumb: if it would belong in a thinker's newsletter, it goes on the personal side. If it would belong in a product changelog or a build log, it goes on the Yonasol side. If it could plausibly belong on either, the question is which version of the idea I actually want to write, and I write that one.
How the two reinforce each other
The split is real. The connection is also real, and that is by design.
The personal writing sharpens the lab's thinking. Writing essays about AI and product under my own name forces a level of clarity that flows back into how Yonasol scopes bets, writes copy, and picks problems. The thinking is upstream of the product taste, and you can usually see one in the other.
The lab gives the writing something concrete to point at. Twenty years of product leadership is one kind of credibility. Running a small AI product lab while doing it is another. Yonasol is where the ideas get tested against actual builds, actual users, and actual verdicts, and that pressure-tests every framework I write about.
Readers who find one often find the other. A reader of my AI and product essays might end up using a Yonasol tool. A Yonasol customer might end up reading the essays. That is fine, even good. The two surfaces do not need to hide from each other. They just do not need to be the same surface.
They tell the same story at different speeds. The story is "a product leader who is genuinely curious about what AI does to operator work, and who builds things to find out." The personal writing tells that story in essays. Yonasol tells it in products. Same story, different evidence.
What I still avoid on each surface
Even with the connection, the two surfaces have a few rules I keep:
- No Yonasol pitches inside personal writing. A bio mention is fine. Pointing at a specific product mid-essay is not.
- No personal performance inside Yonasol content. The Yonasol site is not a portfolio for my career. It is a home for products and the system that builds them.
- No founder face doing the selling. Yonasol's products are sold on their own merits. My writing might earn me a hearing with someone, but the product still has to earn the sale.
- No lazy cross-posting. A post that "fits both" usually does neither well. Two real posts beat one hedged one.
That last one is the hardest. The temptation to recycle is real, and most of the time the right move is to write it twice, in the right register for each surface.
How they meet on purpose
A few places the surfaces touch by design:
- Bios. A one-line "I run a small AI product lab called Yonasol" in my bio is fine. That is not pitching. That is context, and it is the kind of detail that makes a product leader's bio more honest, not less.
- LinkedIn. Yonasol is listed there as a founder role, because that is true. The professional record reflects what I actually do. It does not double as a marketing channel for the products.
- Cross-pollination of ideas. If an essay produces an insight that becomes a Yonasol product, the lineage gets acknowledged inside Yonasol's content without the essay having to carry the pitch.
- Direct conversations. In a one-to-one DM, email, or coffee, the split relaxes. People who are already talking to me get the whole picture. The split is for surfaces, not for relationships.
The point is not purity. The point is to keep each surface doing its actual job most of the time, so that when something does cross over, it carries weight instead of noise.
Why this is more fun
The honest answer is that the split makes both halves of the work more enjoyable.
When my personal writing is not carrying a sales job, I get to think more freely. When Yonasol is not carrying my personal narrative, the products get to stand on their own. Each surface is performing its own job, on its own clock, for its own reasons.
Personal writing is a slow-craft pleasure. Sit with an idea, sharpen it, publish when it is ready. Yonasol is a fast-craft pleasure. Build the thing, run it, document it, sell it. Different tempos, different rewards, both worth doing, neither one diluted by the other.
The short version
Personal writing is for thinking. Yonasol is for building. They share an author and a worldview, and they run on different clocks for different audiences. The two surfaces touch on purpose in bios, in LinkedIn's professional record, and in real conversations, and they stay in their own lanes almost everywhere else.
The split is not separation. It is specialization. Both halves of the work get to be exactly what they are, which lets each one be good at its job and lets me enjoy doing both.
That is the deal, and so far it is the version of building this kind of work that actually feels like me.
Lab Notes are field notes from inside Yonasol. They cover how products get built, how the operating system evolves, and what gets learned along the way.
