The Multi-Entity Evolution: How Slash and OakNorth Are Solving Modern Business Banking's Biggest Pain Point

published on 12 August 2025

Running multiple businesses used to mean juggling multiple banking relationships, countless logins, and endless administrative overhead. But two forward-thinking neobanks are changing that narrative with innovative multi-entity management solutions that recognize how modern entrepreneurs actually work.

The Problem: When One Login Isn't Enough

Serial entrepreneurs, holding company structures, and multi-entity businesses have long faced a frustrating reality: traditional banking wasn't built for their world. Whether you're managing a trading company alongside a holding company, or you're a serial founder building multiple ventures simultaneously, the banking experience has been fragmented, repetitive, and painfully slow.

The numbers tell the story. Many business owners found themselves managing 10+ different banking logins, re-uploading the same documents repeatedly, and even resorting to spreadsheets to track cashflow across entities. It's an administrative nightmare that pulls focus away from what really matters: growing your business.

Two Solutions, One Vision

Two neobanks have recently launched solutions that tackle this exact problem, each with their own approach to streamlining multi-entity banking.

Slash: The Dashboard-First Approach

Slash has gone live with what they're calling "Multi-Entity Management" – a solution that puts simplicity at its core. Their approach centers around a unified dashboard where business owners can:

  • Toggle between entities instantly – No more logging out and back in to check different company accounts
  • View statements and analytics in seconds – Real-time visibility across all your businesses
  • Keep spending and reports organized per entity – Maintain clear financial boundaries while managing everything from one place

The promise is simple but powerful: your businesses shouldn't run on 10 different logins.

OakNorth: Built on Customer Feedback

OakNorth's approach comes from a different angle – they listened to customer frustrations and rebuilt their entire multi-company experience from the ground up. Ben Evans, Senior Product Manager at OakNorth, explains how they heard the same feedback repeatedly: "I want to bank with you for all my companies – but it's too much hassle."

Their solution focuses on eliminating friction at every step:

  • Streamlined onboarding: If you already have one OakNorth business account, adding additional company accounts happens directly from your web dashboard
  • No duplicate documentation: Skip the repetitive form-filling and ID uploads
  • Unified management: Control all your business accounts from one login with the same visibility across each entity
  • Speed by design: Switching between companies takes seconds, not minutes

What This Means for Modern Business Banking

Both solutions represent a fundamental shift in how neobanks think about business customers. Rather than treating each business account as a separate relationship, they're recognizing that modern entrepreneurs operate in interconnected ecosystems of companies.

The benefits extend beyond convenience:

Time Savings: Customers report saving hours on administrative tasks, allowing them to focus on growth rather than banking logistics.

Better Financial Oversight: Unified dashboards provide clearer visibility into cash flow patterns, spending trends, and financial health across all entities.

Reduced Cognitive Load: Managing finances becomes less mentally taxing when everything lives in one organized system.

Faster Decision Making: When you can instantly access financial data across all your companies, strategic decisions happen faster.

The Competitive Landscape

These launches signal a broader trend in business banking. Traditional banks, with their legacy systems and separate product silos, struggle to deliver the seamless multi-entity experience that modern businesses demand. Neobanks, built on modern technology stacks, can offer the flexibility and integration that growing businesses need.

The timing is particularly relevant as we see more entrepreneurs building portfolio companies and sophisticated business structures. The old model of "one business, one bank account" simply doesn't match how many successful entrepreneurs operate today.

Looking Forward

Both Slash and OakNorth hint at even more sophisticated features on the horizon. OakNorth specifically mentions plans for enhanced user permissions and activity management across businesses, while Slash's focus on analytics suggests deeper business intelligence capabilities may be coming.

The real winner in this evolution? Business owners who can finally focus on building great companies instead of wrestling with their banking infrastructure.

The Bottom Line

Multi-entity management isn't just a nice-to-have feature – it's becoming table stakes for any neobank serious about serving modern businesses. Slash and OakNorth are leading this charge, each offering their own take on solving one of business banking's most persistent frustrations.

For entrepreneurs managing multiple entities, the question is no longer whether you can find a bank that understands your needs – it's which solution fits best with how you actually work. And that's a much better problem to have.

The future of business banking is multi-entity by default. These two launches prove that the industry is finally catching up to how modern entrepreneurs actually operate.
