Xomnia

Xomnia is a data and AI consultancy founded in 2013 and headquartered in Amsterdam, the Netherlands, with roughly 85 employees before its June 2025 acquisition of Aurai (a 50-person data and AI team founded by Lars Kieftenburg), bringing its combined headcount to 135+ specialists.

As a Dutch company, all client engagements sit fully within EU jurisdiction and GDPR by default.

Gradient Labs

Gradient Labs is a London-based startup founded in 2023 by former Monzo Bank employees Dimitri Masin, Neal Lathia, and Danai Antoniou, with roughly 46 employees and $13M+ in Series A funding at a $60M valuation. Its flagship product, Otto, is an autonomous agent purpose-built for customer operations in regulated financial services, engineered to resolve complex queries end-to-end while maintaining compliance, reportedly achieving up to a 90% resolution rate with a 98% QA pass rate. Its narrow, financial-services-specific focus and UK domicile make it a fit for buyers wanting deep regulatory fluency over broad horizontal agent capability.

Xomnia vs Gradient Labs: pros and cons

Xomnia
+ Fully EU-domiciled (Netherlands), with all engagements sitting inside GDPR jurisdiction by default
+ 135+ specialists post-acquisition gives it meaningful bench depth for a boutique-scale firm
+ Named delivery experience across manufacturing, finance, telecom, energy, and government
+ Over a decade of data and AI consultancy history since 2013
- Recent acquisition (2025) means combined-team integration is still relatively new
- Minimum engagement figures are not published, requiring direct sales contact for early budgeting
- Agentic AI is one part of a broader data-and-AI consultancy practice, not the sole focus
Gradient Labs
+ Founding team's direct experience at Monzo (a regulated UK bank) feeds real compliance fluency into Otto
+ Named, benchmarked production agent with disclosed resolution-rate and QA-pass-rate figures
+ Venture-backed ($13M+ Series A) with runway to keep investing in the product
+ UK domicile with a narrow, deep focus on regulated financial services specifically
- Very narrow focus (financial-services customer operations) — not a fit for other verticals or broader custom agent builds
- Small team (~46 employees) limits capacity and account-management bandwidth
- As a product company rather than a services firm, engagement is closer to platform licensing than bespoke development
