About Us
Who Built This, and Why Transparency Mattered
A small team based in Sibiu, Romania, that decided auditable software was worth building from scratch.
The Company Behind the Platform
Co of Portland began as a tool we built for ourselves — then for traders who asked the same questions we did.
Co of Portland was founded in Sibiu in 2019 by a group of engineers and systematic traders who had grown skeptical of trading software that could not explain its own decisions. The team had collectively spent over a decade working across quantitative finance desks and software consultancies in Romania and Central Europe. The problem they kept returning to was the same: automation tools that executed trades without producing any record a non-developer could read. The company's response was to build the audit trail first — then construct the execution engine and risk controls around it. Today the team of eleven works from offices on Strada Mitropoliei, with onboarding support available in English. The platform serves retail traders across Romania and the broader EU, including clients in Germany, Poland, and Austria. Our teal-modern interface is not a stylistic choice alone — it reflects a deliberate visual philosophy: clear contrast, unambiguous status indicators, and no decorative elements that compete with information. A trader looking at the dashboard should be able to read the state of their strategy in under ten seconds.
How We Work, and Where the Limits Are
Concrete process and honest boundaries — because both matter before you commit.
Our onboarding process begins with a strategy review call — typically thirty minutes — where one of our engineers validates that your rule set can be expressed in our execution model. Following that, we configure the backtesting run and deliver the performance report within 24 hours. Broker connection is completed using your account's official API credentials; we never hold or request your broker password. Strategies are deployed in a paper-trading environment first, then moved to live execution only after your explicit written confirmation. We work with traders who have defined, rule-based strategies. We do not provide trading advice, portfolio management, or signal services. If your strategy relies on discretionary judgment or requires manual overrides more than twice per week, the platform is unlikely to be the right fit — and we will tell you that plainly during the strategy review call rather than onboard you into a subscription that will not serve you well. Performance outcomes depend on market conditions, and no configuration of our software changes that. We are the infrastructure; the strategy and its risks are yours.
A Client Perspective on the Onboarding Process
“The strategy review call took twenty-five minutes. The engineer told me upfront that one of my exit conditions would need to be rewritten because it referenced an indicator the engine does not support. That kind of honesty before the contract was signed told me more about this company than any marketing copy could.”
