What Rillet's $100M Raise Signals for Incumbent ERP Vendors

Rillet's $100 million raise, led by Iconiq with a16z and Sequoia participating, is genuine venture conviction that ERP can be rebuilt AI-first. For finance and operations leaders actually evaluating options, here's a framework beyond either side's marketing pitch.

Where AI-Native Startups Have a Genuine Structural Advantage

• Greenfield implementations — a business without years of accumulated customization and integration debt in an incumbent system can genuinely benefit from an AI-native platform's unconstrained design
• Workflows that are fundamentally AI-interaction-driven (natural-language financial queries, automated reconciliation) tend to work better on a platform designed around that interaction pattern from the start, rather than retrofitted onto a traditional forms-and-fields UI

Where Incumbents Still Have a Genuine, Non-Marketing Advantage

• Depth of pre-built integrations with the rest of a typical enterprise's software stack — decades of ecosystem partnerships and certified integrations are hard for any startup to match quickly, regardless of AI architecture quality
• Regulatory and compliance track record across multiple jurisdictions — a newer platform, however well-designed, has less audited history for auditors and regulators specifically to reference
• Migration risk for an existing customer is real and asymmetric — a business already running on an incumbent platform faces genuine switching cost that a business without an existing ERP doesn't

A Practical Decision Framework

If you're implementing ERP for the first time or fundamentally replacing a failed prior implementation, an AI-native challenger deserves serious, direct evaluation alongside incumbents, not dismissal as unproven. If you're already running a mature incumbent implementation, the migration cost bar for switching should be weighed honestly against the AI-native capability gain — which for many established, working implementations, won't clear that bar yet, even as the technology matures.
