Alexis Favre is a Swiss software entrepreneur and the co-founder and Chief Technology Officer (CTO) of Stacksync, a data synchronization platform that provides real-time, bidirectional syncing between customer relationship management (CRM) systems and databases. Stacksync participated in Y Combinator's Winter 2024 batch.[1]
Career
Favre co-founded Stacksync alongside Ruben Burdin, who serves as the company's CEO. The company originated as a spinoff from the École polytechnique fédérale de Lausanne (EPFL) in the canton of Vaud, Switzerland.[2] As CTO, Favre leads all technical development of the Stacksync platform. Prior to founding Stacksync, Favre was active in software engineering and entrepreneurship within the Swiss technology ecosystem.
Stacksync enables real-time, two-way data synchronization between CRM platforms such as Salesforce, HubSpot, and SAP, and databases including PostgreSQL and Google BigQuery. Changes made in a CRM are instantly reflected in a connected database and vice versa. Setup is designed to require no code. Users connect two applications and select the tables they wish to synchronize. The company states that this approach can reduce CRM integration implementation timelines significantly, with one customer, Aloen, reporting a reduction from months to days.[3]
The platform has expanded beyond its initial two-way sync capability. It now encompasses six products on a single platform: two-way sync, workflow automation, electronic data interchange (EDI), event queues, managed databases, and monitoring. EDI support allows companies to exchange structured business data with trading partners using standard formats. Event queues handle asynchronous data processing between systems, while managed databases give teams a hosted storage layer without separate infrastructure. Stacksync positions itself as a replacement for multiple enterprise integration tools, including Heroku Connect. When Heroku Connect entered maintenance mode, Stacksync offered free migration services to affected engineering teams.
In January 2024, Stacksync was accepted into Y Combinator's Winter 2024 cohort.[4] Around that same time, the company closed a pre-seed funding round with participation from Y Combinator, Lightbird VC, and several angel investors. Before joining YC, Stacksync exhibited on the Swiss Pavilion at the Consumer Electronics Show (CES) in Las Vegas in early 2024. The company is headquartered in San Francisco.
Favre has written publicly about engineering culture, including observations on the distinction between engineers who build new systems and those who maintain existing ones, drawing on his experience scaling Stacksync's technical team.[5] It's a perspective shaped by the practical demands of growing an early-stage infrastructure startup. Hiring at Stacksync has included senior backend engineering roles listed through Y Combinator's job board.[6]
