What SixSides does
SixSides is a privately held engineering services firm founded in 2017 and headquartered in Buenos Aires, Argentina (despite one firmographic field listing Tandil; the company's own website, privacy policy, and case studies consistently identify Buenos Aires as HQ). The firm provides dedicated senior engineering squads — typically a Lead/Architect, two to four engineers, and an optional QA — that embed into client organizations and own delivery from MVP through growth-stage. Co-founders Martin Zavatto and Andres Ponte (the "Daniel" referenced in client testimonials is treated as a partner identity by the company; the structured leadership record lists Zavatto and Ponte) lead client relationships directly.
SixSides' core technical differentiator is an AI-augmented development lifecycle applied across architecture and design, build and development, testing and QA, and release and operations, with all AI-generated outputs validated by senior engineers. The firm operates a dedicated R&D function that continuously tests new AI tools. Publicly disclosed client work includes the iPartners investment platform (built from the ground up since 2017, scaling from 13 core engineers at baseline to 31 at peak, managing AUD 4.5B+ AUM and 10,000+ active investors), the Tertulia AI-driven bookstore (since 2021, with five engineers delivering backend, mobile, data, and e-commerce across tens of millions of indexed books and hundreds of millions of processed tweets), and the Tertulia for Authors website builder (launched 2024, scaled to thousands of paying subscribers within five months of release).
The business model is straightforward professional services revenue: recurring fees for embedded engineering capacity priced at a discount to NYC-based senior teams, with NDAs and clear IP ownership as defaults. Go-to-market is partner-led direct sales supported by a content-marketing website and a LinkedIn presence, targeting growth-stage technology companies in the Americas and Europe, leveraging Buenos Aires' GMT-3 timezone for 1–2-hour overlap with US East Coast and European business hours. Pricing is not publicly disclosed and no information is available on customer count beyond the three named case studies.
