We are Pleo - it's a part of who we are as a tech company. We help customers to delegate employee spending through an expensing platform. This ends out of pocket spending, encourages autonomy and trust in employees, and takes a huge burden off the finance team. Our product is a SaaS expensing platform that comes with physical pre-paid cards (so with a fintech twist) that are then distributed to all employees of the company. The best part is we're all users of Pleo ourselves - so it's a very applicable tool. It impacts anyone in a company who could spend money on behalf of their business - be it a coffee with clients or a Mac for a new hire. Working at Pleo means you're working on something very exciting: the future of work. Through fintech we've seen a way to impact how people work; we think company spending should be delegated to all employees and teams, that it should be as automated as possible, and that it should drive a culture of responsible spending.

The way businesses buy stuff is completely broken. Whether it’s SaaS, hardware, or contractors, the average B2B purchase takes over 3 months, requires 50+ emails, and involves multiple different stakeholders (IT, Legal, InfoSec, Finance, etc.). No one likes the way it is and it’s slowing businesses down. Omnea’s platform handles the entire purchasing process: giving employees an easy place to make requests (Intake), managing the necessary approvals for the purchase to be made (Approvals Engine), and automating all renewals management & supplier risk assessments. Omnea gives both buyers, and finance & procurement leaders critical visibility into how, when, and why money is being spent. Given the current market's increased focus on capital efficiency, there has never been a more vital time for businesses to use Omnea and get control of their spend. This is why we're one of the fastest growing Series A B2B businesses in Europe, backed by tier-1 VCs like Accel, First Round, & Point Nine. Welcome to Spend Control 2.0 — built for tougher times.
