Company Overview

About Bitstack

Bitstack is a Paris-based Bitcoin savings and investment platform — backed by Y Combinator with $9.1 million raised including a $5.25 million Series A led by ISAI in December 2024 — providing French retail investors with a simplified mobile-first application to buy, hold, and earn on Bitcoin through automatic savings rules (roundup purchases, recurring DCA buys, cashback in Bitcoin). Founded in 2019 and serving 150,000 users who have collectively saved €125 million in Bitcoin with $3.5 million in revenue in 2024, Bitstack has established itself as France's leading Bitcoin savings app by democratizing cryptocurrency access for mainstream investors who find traditional crypto exchanges complex and intimidating.

Business Model & Competitive Advantage

Bitstack's consumer-friendly Bitcoin-only approach differentiates from multi-asset crypto exchanges: rather than offering hundreds of tokens with complex DeFi features, Bitstack focuses exclusively on Bitcoin with savings-oriented features (automatic roundup purchases that convert spare change from daily purchases into Bitcoin, recurring DCA schedules, and a European Bitcoiner community). The French regulatory framework (Bitstack is registered with the AMF as a PSAN — Prestataire de Services sur Actifs Numériques) provides the compliance foundation that attracts mainstream French investors wary of unregulated crypto platforms after the FTX collapse. The neobank positioning (simple, app-first, no fees for basic services) echoes Revolut and N26's consumer bank success in France.

Competitive Landscape 2025–2026

In 2025, Bitstack competes in the European Bitcoin retail investment market with Coinbase (NASDAQ: COIN, dominant crypto exchange), Bitpanda (Austrian crypto investment platform, $370M raised), and Revolut (UK neobank with built-in crypto, $45B valuation) for French and European retail Bitcoin investment. The Bitcoin bull market (2023-2024 Bitcoin appreciation, ETF approvals in the US) and growing European retail investor Bitcoin interest create favorable market conditions for Bitcoin savings platforms. Y Combinator backing connects Bitstack with the fintech investor community. The 2025 strategy focuses on the roundup and DCA product features that drive habit-based Bitcoin savings, expanding to other EU markets (Germany, Spain) where French regulatory compliance frameworks are applicable, and building the Bitcoin inheritance and estate planning features for the growing Bitcoin-holding household demographic.
