Hartza Capital is a French FinTech company founded in 2025 by Aurélien Perrier. Our founding conviction: technology and finance are not two separate disciplines — they reinforce each other. A well-designed cloud infrastructure produces better financial analysis. And rigorous financial analysis guides technology architecture choices. Both move forward together.
Technology in Service of Finance
Financial markets generate volumes of data impossible to process manually. Tick-by-tick prices, options flows, earnings call transcripts, regulatory filings, macroeconomic data — a human analyst can only exploit a tiny fraction. That’s where our infrastructure comes in.
Hartza Capital operates a cloud-native stack on AWS specifically designed for financial research:
- Collection: real-time ingestion of market feeds via specialized financial APIs, stored in time-series databases
- Processing: normalization and enrichment pipelines for raw data — computation of operational metrics, detection of statistical patterns, company scoring
- Modeling: quantitative strategy backtesting, valuation model construction, scenario simulation
- Production: deployment of trading algorithms in containerized environments (Docker), monitoring under real market conditions
This infrastructure is not a peripheral tool. It’s the engine that allows our analyses to go beyond the annual report and analyst consensus.
Finance Guiding Technology
Technology without finance produces elegant models that don’t correspond to anything real. At Hartza Capital, every architectural choice answers a precise financial question.
Why a time-series database rather than a classical relational database? Because market data is fundamentally sequential and financial queries — “give me all days where volume exceeded 3 times the 20-day average” — need to execute in milliseconds. Why backtest on tick-by-tick data rather than daily closing prices? Because intraday strategies behave differently depending on market microstructure, and an approximate backtest leads to poor decisions in production.
Financial rigor demands technical rigor. And technical rigor makes financial rigor scalable.
Our Research Philosophy
Mainstream financial research suffers from two structural biases: bank sell-side research follows the interests of the issuers who pay them, and the financial press sacrifices depth for speed. Hartza Capital produces independent, quantitative, and transparent research.
Independent. We invest our own capital and receive no compensation from the companies we analyze. When we hold a position in an analyzed security, we systematically disclose it at the beginning of the article.
Quantitative. Each analysis crosses market data processed by our infrastructure with in-depth fundamental analysis — annual reports, SEC/AMF filings, earnings call transcripts. Our valuation models are built from scratch.
Transparent. We document our assumptions, sources, and methodology. What we write, you can replicate.
Our Founder
Aurélien Perrier built his expertise at the exact intersection of these two disciplines over more than a decade, developing in parallel a deep understanding of financial markets and technical mastery of the systems that process them.
Financial Experience
- 10 years of stock market and equity investing
- 7 years of credit analysis and corporate lending
- 5 years of real estate investing (direct and crowdfunding)
- 3 years of private equity exposure
Technical Expertise
- 8 years of production algorithmic trading system development
- Design of market connectivity infrastructure (Interactive Brokers Gateway, open-source on GitHub)
- Building financial data pipelines on AWS cloud
- Backtesting on tick-by-tick data, deployment and monitoring of strategies under real market conditions
The two dimensions are not additive — they are multiplicative. Knowing how to read a balance sheet and knowing how to build the API that collects market data in real time produces an analytical capability qualitatively different from either taken separately.
