A society of builders.
Before Adelphi was a studio, it was a circle: technological people meeting to argue about the future and their place in building it. No audience, no feed to perform for. That circle is still here — closed, deliberate, and the reason everything else exists.
How the circle formed
Formed by what was missing
Adelphi began as an answer to a gap: in Bulgaria, ambitious deep tech ideas found no early support, no informed capital, and no bridge between science and product — and we had watched what happens when power lands with capital that has no principles. So we built our own circle: founders, engineers, scientists, and investors, united behind a common goal.
The first community-backed products
The cumulative effort of over fifteen members produced the community's first ventures in identity and interview-analysis AI — proof that a trusted circle can build what isolated founders cannot. Those ventures live on today inside the Adelphi portfolio.
A core society, deliberately small
The community matured into a core society with limited entry: members are admitted by invitation and voting, meet in small regular gatherings, assemble monthly, and participate in joint ventures. Confidentiality, loyalty, and consistency are the price of a seat.
The studio era
Adelphi Group is the community's execution engine — a venture studio that turns the circle's expertise, capital, and networks into operating companies. The society remains its beating heart.
Five circles, one core
The core society sits at the center. Around it, five overlapping circles of activity — each one a way the community compounds.
Technology
Engineers and builders combining expertise into complex solutions no single team could ship.
Science
Bridging research and product — the technology-transfer path our country never built.
Investments
Informed capital from people who build, backing ambitious ideas at the earliest stage.
Advisory
Founders guiding founders — strategy, go-to-market, and hard-won lessons shared freely.
Philanthropy
Organized social entrepreneurship and impactful giving for the next generation of Bulgarians.
What membership means
Loyalty over cash
One success is everyone's success. We are there for each other in the hard times, not just the wins.
Confidentiality
What is discussed in the circle stays in the circle. Trust is the entire architecture.
Consistency
We show up — to the gatherings, to the work, to each other. Presence is a commitment.
No bullshit, real results
No social media theater. Shipped products, live deployments, and real outcomes.
Above all, have fun.
“I am starting this community because I have witnessed first-hand the power that we have when united behind a common goal — and I know for a fact that the limits ahead of us are very few, and are yet to diminish further. Together we can make a true difference in this world, so that the generations ahead of us will once again be proud to call themselves Bulgarians. Let's make the future brighter, together.”
Entry is earned
We accept a handful of people each year, by invitation and voting. The door opens through work: an open call, a venture, a collaboration.
