From idea to business — starting, building and scaling technology companies hands-on, from the first prototype to exit.
Companies built
Digital Logic is a bootstrapped company builder, started in 2014 in Porto, Portugal. Each company is built in-house from the first prototype through expansion and exit.
Every venture is fully independent — grounded in deep technological focus and real market experience across Fintech, IC Design, Medtech and E-Commerce, with several already created and successfully exited.
SAAS for SME with complete suite of Accounting, Billing, Purchases, Inventory and Salaries. Market leader in Portugal with 150.000 SME, 15.000 Accountants and 500.000 active users. Provides automated document classification and payments integration.
Exited to Oakley in 2022
Fintech SAAS for Financial and Fiscal audit automation and large scale analytics. Customers include 5 European Tax Authorities, several large corporations and over 10.000 SME. Provides automatic findings and machine learning for audit improvement.
Exited to Sovos in 2021
Leading price comparison website and marketplace in Portugal. B2C service with 60 million visits per year, 2 million products and 1.500 online stores. Better shopping experience through curated information, user experience, payment security and improved delivery.
Semiconductor and IC design specialized in subthreshold microchip architecture. The technology is able to reduce the power consumption in idle mode of any other microchip by several orders of magnitude, increasing 10 fold the battery lifetime of IoT systems.
Deep Neural Network for Electrocardiogram (EKG) exams classification. Able to provide over 99% accuracy on over 100 different type of diagnosis. Cardiolife cloud software improves significantly the productivity of doctors and technicians in their diagnosis workflow.
Price Intelligence for e-commerce. SAAS able to provide specialized analytics to Marketplaces, Stores, Brands and Consumers.
AI-first accounting for SMEs and independent professionals. Fully digital team based in Porto — using advanced AI to automate accounting, tax preparation, financial reporting and payroll end to end.
Technology research and its practical application have always been at the core of the work — staying on the leading front of techniques that create strong differentiation and large productivity gains. Some current focus areas:
A full-featured library built on PyTorch, with models for signal, image and text. Applied across healthcare, fintech and e-commerce — from ECG interpretation to fuzzy matching of product prices to default prediction on bank loans.
An in-memory DBMS that runs on the GPU for high-speed access, large-scale data manipulation and real-time OLAP analytics — several orders of magnitude faster than the alternatives.
A Robotic Process Automation library for data collection and real-time actuators, focused on e-commerce and accounting software — aiming for human-level efficacy at machine speed.
Breakthrough integrated-circuit designs for low-power management, the Internet of Things and energy harvesting, built on patented sub-threshold technology.
Modern AI stack — large language models, retrieval-augmented generation, tool use and autonomous agents — applied to automate complex workflows end to end, from document understanding and reasoning to multi-step orchestration across accounting, audit and product systems.
Serial entrepreneur & engineer
A serial entrepreneur and engineer based in Porto, building and exiting technology companies for over 25 years — across fintech, healthcare, IC design, navigation, media and IT.
With a background in Electrical and Software Engineering, started out as a Computer Scientist and returned to hands-on building in 2018, focused on deep neural networks.
