Onboarding Friction for High-Volume FX/Crypto Prop Traders

We're currently scaling our proprietary trading firm, primarily in high-frequency $EURUSD and $BTCUSD pairs. The onboarding process with several prime brokers and crypto exchanges has been consistently clunky for entities like ours. The KYB requirements, while understood, often feel like they're designed for a different type of institution, with redundant requests and slow verification times. It significantly impacts our ability to diversify liquidity providers efficiently. Anyone else experience this, and what workarounds or specific firms have streamlined this process for high-volume prop desks? We're talking about firms that manage significant AUM and require fast access to deep liquidity, not just retail-level access.
