We're MegaCpp
Company, founders, and one public product
Datasunrise OÜ is the company in Tallinn, Estonia behind the MegaCpp brand. Our public focus is simple: one product called SLM Ensemble, one domain centered on C++, and a technical story that stays inspectable.
We keep expanding the public documentation, examples, and technical writing as the stable product surface becomes easier to describe cleanly.
Why MegaCpp exists
MegaCpp started from a fairly practical observation: generic AI copy tends to become least useful exactly where C++ work becomes most expensive. Cross-file edits, build-aware reasoning, refactors, and review loops all need tighter grounding than a generic assistant usually provides.
That pushed us toward a narrower public position. Instead of presenting a sprawling stack of semi-public products, we chose one product surface and a clearer separation between public claims, technical notes, and active research.
The result is a simpler company story: Datasunrise OÜ operates the MegaCpp brand, SLM Ensemble is the one public product, and the surrounding articles explain how the engineering work is evolving.
What we optimize for
Specialization Over Sprawl
MegaCpp is intentionally narrow. We would rather do one C++ product well than pretend to cover every software task at once.
Grounded Public Writing
Public pages should separate durable claims from experimental work. The blog and documentation carry the deeper technical detail.
Developer Workflow First
C++ work is shaped by repositories, build systems, review cycles, and compiler context. That is the product surface we care about.
Build in the Open
We publish notes, samples, and references because engineering claims are easier to trust when readers can inspect the supporting material.
Short version
Datasunrise OÜ is formed
Datasunrise OÜ was registered in Estonia on March 23, 2022 and now operates the MegaCpp brand.
MegaCpp direction becomes explicit
The team narrowed its public scope to C++-focused model work, public documentation, and technical writing around that domain.
SLM Ensemble becomes the public product
SLM Ensemble is presented publicly under the MegaCpp brand through one product page, supported by technical articles and architecture docs rather than a broad product matrix.
Founders-led build phase
David Gornshtein and Boris Tamarkin continue shaping the public technical story, company presence, and product direction.
