Citibox Overview

About Citibox

Citibox is a Madrid last-mile logistics company founded in 2015. It installs connected parcel boxes in residential buildings so delivery companies can leave e-commerce orders securely when recipients are away. Residents receive digital notification and collect packages later, while carriers reduce repeated delivery attempts, distance traveled and time spent at individual doors. The company combines physical mailbox infrastructure, access technology and logistics software. It serves property communities, logistics operators, retailers and consumers through a shared delivery network. Citibox earns recurring service and network revenue and has expanded into pickup points and returns. Its acquisitions of mobile-access company iOmando and parcel-network operator Celeritas broadened the platform beyond its original smart boxes.

Jan 2021SeedAlma Mundi Ventures (lead)$13MCitibox operates a technology platform that connects last-mile delivery couriers with online shoppers through a network of smart parcel lockers installed inside residential buildings. The system enables 24/7 package delivery and pickup by automating building access and sending delivery notifications, reducing failed deliveries and enhancing courier productivity. Shoppers receive parcels securely in their buildings at their convenience, while property owners and managers benefit from streamlined parcel management and improved resident satisfaction. Citibox solution integrates with mobile apps and leverages automated locker networks to handle online orders for residential settings, aiming to lower delivery costs and improve accessibility for urban residents. Alma Mundi Ventures participated in Citibox's seed round in 2021.
Jun 2019SeedBernardo Hernandez; Luis Miguel Gilpérez; Richard Alden; Santiago Fernández Valbuena; Javier Rubio$13MCitibox is a Spanish smart mailbox company that raised capital in a Series A round on June 18, 2019, with investors including Bernardo Hernandez, Javier Rubio, Luis Miguel Gilpérez, Richard Alden, and Santiago Fernández Valbuena. The company subsequently expanded operations and later raised €80 million in debt financing on July 2, 2024, led by Growth Credit Partners and CoVenture. In September 2023, Citibox acquired Celeritas. The company operates a network of smart mailboxes throughout Spain and has built operations with approximately 80 employees.
Jun 2018Series AAndreas Mihalovits$7MCitibox announced a EUR 6.2 million Series A financing on 20 June 2018, with SEUR contributing EUR 750,000 and Andreas Mihalovits identified among the round's investors. The transaction is separate from the January 2018 early financing already recorded for Citibox and reflects the larger round announced later in the year. Citibox installs connected parcel boxes in residential buildings so carriers can complete deliveries when recipients are not home. Residents receive a mobile notification and retrieve a parcel using a transaction-specific code, while logistics providers consolidate stops and reduce failed delivery attempts. The company earns revenue from parcel operators that benefit from lower delivery costs and higher route productivity rather than charging the recipient for each collection. The capital supported deployment across Madrid and preparations for expansion to Barcelona and other large European cities.
Jan 2018SeedBig Sur Ventures (lead)$3M-
Jan 2017Undisclosed stageBStartup-BStartup invested in Citibox during 2017, establishing an equity position in the company through Banco Sabadell's early-stage startup program. The official portfolio identifies the company, the investment year and BStartup's continuing or historical relationship with the target. Citibox application that helps to receive delivery of products and services at home, even if the recipient is not at home. That operating description identifies the target's product and customer problem and distinguishes it from similarly named businesses. BStartup's program combines direct equity investment with specialist banking and access to Banco Sabadell's operating network for Spanish technology companies. The official portfolio continues to present the company as a current BStartup holding. The live database contains no BStartup participation for Citibox in the official investment year, and the target's other recorded financings fall outside the same-event collision window. This candidate therefore records the missing BStartup investment while leaving unsupported co-investors, stage detail and monetary terms blank.
Jan 2016Pre-seedBonsai Partners (lead); Mission; Carlos Blanco; Big Sur Ventures$800KCitibox completed a seed financing during 2016 with Big Sur Ventures and Bonsai Partners. Citibox develops smart parcel boxes and related logistics software for residential buildings, allowing carriers to deposit e-commerce deliveries securely when recipients are absent and enabling consumers to collect them later. The system aims to reduce repeated last-mile delivery attempts, congestion and emissions while giving logistics operators a shared delivery point. Big Sur has described itself as the company's first venture-capital investor, and the firm's current portfolio independently records 2016 as its Citibox investment year. The financing timeline also identifies Bonsai, which is already attached to the database row. Because the difference is below the repository's material correction threshold and the accessible evidence does not fully reconcile all tranches, this repair adds the missing investor and documentation without changing the stored amount.

Latest Acquisitions by Citibox

Celeritas
iOmando
Description
Celeritas is a Spanish parcel and e-commerce logistics company based in Madrid. It operates a network of convenience points where consumers can collect online purchases or leave returns, complementing delivery to homes and businesses. Retailers and logistics partners use the network for last-mile and reverse-logistics services across Spain and Portugal. The company manages transport, parcel routing and handoff through physical locations and supporting technology. Its customers are businesses that need distribution coverage, while end consumers use the pickup and return points. Celeritas earns logistics and delivery-service revenue rather than payment-processing fees. Citibox acquired the company in 2023 for EUR 21 million, combining the point network with Citibox's residential smart parcel boxes.
iOmando was a Barcelona access-control technology company founded in 2011. It developed software that allowed a smartphone to open connected doors, gates and parking entrances, replacing or supplementing physical keys and remote controls. Property administrators could manage permissions digitally and grant or revoke access without distributing new hardware credentials to each user. The product served residential communities, car parks and other managed facilities. iOmando combined connected devices with mobile and cloud software and earned product and service revenue from deployments. Citibox acquired the company in 2017 to add building-access capability to its smart parcel-box network. The technology and team were subsequently integrated into Citibox rather than continuing as a standalone business.
