What Prolog does

Prolog is a Brazilian SaaS company headquartered in Palhoça, Santa Catarina, founded in 2016 under the legal entity ZALF SISTEMAS LTDA, that builds cloud-based fleet management software for the logistics and transport sector. The platform is organized around three core modules: Gestão de Pneus (Tire Management), which tracks tire wear, cost-per-kilometer, tread depth, calibration, and recap lifecycles; Checklist Eletrônico (Electronic Checklist), which replaces paper inspection forms with mobile-based digital checklists and automatic reports; and Gestão de Manutenção (Maintenance Management), which digitizes work order workflows from opening to resolution. The product is delivered as a web application and an Android mobile app, and is extended by an open API that enables integration with ERP systems and third-party fleet management platforms. Supporting the core platform, Prolog publishes an economic savings calculator, a fleet maturity quiz, and online courses on tire and maintenance management.

The company operates a sales-led go-to-market with 'Request a Demo' and 'Talk to a Specialist' as primary conversion points, targeting six vertical segments: cargo transport, passenger transport, industrial operations, agricultural transport, mining, and vehicle rental. Prolog claims more than 1,500 fleet operations as customers in Brazil and abroad, and publishes case studies with named enterprise customers including Transportadora Translecchi (~590 plates, 7,900+ tires), Conlog, and Avilan Transportes (a 10+ year customer). The revenue model is subscription-based SaaS with annual billing, modules sold separately or as an integrated suite, and payment processed via Boleto Bancário; specific pricing is not publicly disclosed. Content marketing—blog, YouTube, Instagram, Facebook, LinkedIn, WhatsApp community, e-books, spreadsheets, and checklists—feeds the top of funnel. The company is privately held, with 51-100 employees, reported 70% year-over-year revenue growth, and completed a R$5.5 million seed round led by US-based Parceiro Ventures in February 2024, with stated plans to double both revenue and headcount in 2024.

Core offering

Prolog sells a cloud-based SaaS fleet management platform delivered through a web application and Android mobile app. The platform combines three core modules — Tire Management (wear, CPK, calibration, recap tracking), Electronic Checklist (digital vehicle inspections with automatic reports), and Maintenance Management (work order workflow) — and exposes an open API for integration with customer ERPs and fleet management systems. Subscription access is licensed per registered user on a non-transferable basis with billing accepted via Boleto Bancário.

Product overview

Prolog offers a unified fleet management platform with three core integrated modules: Gestão de Pneus (Tire Management), Checklist Eletrônico (Electronic Checklist), and Gestão de Manutenção (Maintenance Management). These modules work together to provide complete fleet oversight—tire management handles wear tracking, calibration, and recap optimization; electronic checklists digitize vehicle inspections; and maintenance management coordinates repair workflows. Supporting the core platform, Prolog provides an Economic Calculator for ROI demonstration, the Quiz Mestre da Frota for maturity assessment, and two educational courses on tire and maintenance management. The platform is accessible via web application and Android mobile app, and offers an open API for ERP integration.

Direct peers

• Cobli: Brazilian SaaS fleet management and telematics platform serving logistics and transportation companies with vehicle tracking, maintenance, and driver management. Direct regional competitor with overlapping mid-market and enterprise customer base in Brazil.
• Fleetio: Cloud-based fleet maintenance and management software offering preventive maintenance, fuel tracking, and inspection workflows. Highly comparable product architecture to Prolog's maintenance and electronic checklist modules, serving a similar mid-market fleet operator persona.

Broad incumbents

• Samsara: Public IoT/fleet management platform offering telematics hardware, video-based safety, and SaaS software across asset-intensive industries. Competes with Prolog at the high end of the Brazilian logistics market with bundled hardware-software contracts.
• Geotab: Global telematics incumbent with deep fleet tracking, productivity, and compliance offerings distributed through extensive reseller networks. Comparable in addressing fleet operations across multiple verticals but at significantly larger scale.
• Verizon Connect: Enterprise fleet and asset management suite combining telematics, maintenance, and routing. Competes broadly with Prolog for larger enterprise fleet accounts across geographies.
• Trimble Transportation: Established transportation and fleet software provider offering TMS, fleet maintenance, and telematics solutions. Comparable in addressing commercial transportation workflows but at a much larger enterprise scale.

Regional players

• Onixsat: Brazilian fleet tracking and telematics company serving cargo and passenger transport operators. Overlaps with Prolog's customer base in Brazilian transport verticals with a more hardware-led, tracking-centric offering.
• Autotrac: Brazilian provider of fleet tracking and asset management solutions with hardware and software components. Competes with Prolog in the cargo transport segment in Brazil with a more telematics-native product.
• Sascar: Brazilian fleet management and telematics brand now owned by Michelin, offering tracking, tire management, and driver services. The Michelin-owned tire-management angle makes Sascar a particularly close functional comparator to Prolog's core tire module.

Emerging players

• Azuga: Fleet tracking and driver behavior platform offering GPS, maintenance, and rewards-based safety programs. Overlaps with Prolog's electronic checklist and maintenance modules in mid-market fleet use cases.
