Frontera Agritech is an agricultural biologicals company building integration-first solutions designed to work within existing farming value chains — not against them. We develop microbial crop treatment products that enhance plant resilience, improve nutrient uptake, and support sustainable yield outcomes. Our approach is grounded in practical agronomy: products that fit seamlessly into current workflows, compatible with standard equipment, existing chemistries, and established distribution channels. Our Focus Areas: 🌱 Biological Crop Treatments — Microbial formulations that strengthen crops against abiotic stress, improve soil biology, and reduce dependency on synthetic inputs. 🔬 Field-Validated Science — Every product is backed by rigorous multi-site field trials across diverse geographies and growing conditions, ensuring performance you can trust. 📦 Integration-First Design — Our formulations are designed for compatibility. They work alongside conventional crop protection programs, delivered through the partners and retailers farmers already rely on. Why Frontera: Agriculture faces a dual challenge: producing more with less while transitioning toward sustainable practices. We believe biologicals are a critical part of the answer — but only if theyre practical, proven, and easy to adopt. Thats why we focus on removing barriers to adoption rather than asking farmers to change how they work. Our team brings together decades of experience across agronomy, microbiology, agricultural commerce, and scaling operations in global markets. Were building Frontera to bridge the gap between biological innovation and real-world farming. Headquartered in Malaga, Spain with field operations and trial networks across key agricultural regions.

You started a business to do meaningful work — not to chase receipts, reconcile bank feeds at midnight, or remind your team about expense reports for the third time. Yet for most European SMEs, daily financial operations are still a grind. Invoices pile up in inboxes, payroll eats a full day every month, and the tools that were supposed to help just created more tabs to manage. Rise fixes this. Our AI-powered platform takes over the repetitive financial work that drains your time — pulling data from your email, calendar and bank feeds, matching invoices, preparing bookings and flagging what actually needs your attention. Qualified accountants verify everything, so the books stay clean without you lifting a finger. We built Rise for professional services firms and SaaS companies with 5–50 employees across Europe — the businesses too complex for self service tools, but too lean for a full back-office. Rise Financial Group is headquartered in Switzerland, combining Swiss financial precision with Nordic engineering excellence. Stop managing your finances. Start managing your business.
