Built for investors who refuse to guess.
Onlysites began as a response to a simple frustration: portfolio data scattered across exchanges, tools that explain the past instead of the present, and decisions made on incomplete information. We set out to close that gap.
From a personal problem to a shared platform.
Onlysites was founded by people who were, themselves, managing positions across multiple exchanges on the side of other careers. The existing tools were either built for institutions with dedicated analysts, or too shallow to support a real decision. Neither option fit.
So we built the platform we wished existed: one that pulls together fragmented data, applies consistent analysis, and presents it in a way that supports a decision rather than just describing a chart. What started as an internal tool became Onlysites.
We remain a focused team, intentionally small, building for a specific kind of user rather than trying to be everything to everyone.
Give serious side-activity investors an institutional-grade view, without the institutional overhead.
We believe good decisions require good inputs. Our mission is to make multi-exchange portfolio analysis accessible, consistent, and genuinely useful to people who have real responsibilities beyond managing their investments — without pretending to replace independent judgment or professional financial advice.
Principles that shape how we build.
Signal over noise
We prioritise information that supports a decision over information that simply fills a dashboard.
Same standard, every time
Analysis should not vary with mood or memory. We apply the same rigor to every account, every exchange, every time.
No manufactured urgency
We present what the data shows. We do not dress up outputs to create excitement where none is warranted.
Built for limited time
Our users have other jobs and other responsibilities. We design for people who need answers quickly, not a new full-time hobby.
A focused group, not a faceless company.
Onlysites is built by a small, cross-disciplinary team spanning data engineering, market analysis, and product design. We work closely together and stay close to the people who use the platform, because the product only stays useful if it keeps reflecting real needs rather than internal assumptions.
