Onshore

AI-driven tax automation and credits platform

Overview

Onshore provides an AI-native SaaS platform that automates corporate tax workflows to identify, optimize, and defend incentives like R&D credits, integrating with payroll, GL, and project systems to validate evidence against IRS standards in real time. It uses an AI-first architecture to perform detailed business-component analysis, automating data ingestion and using proprietary ML with expert oversight to produce audit-ready, traceable tax credits and faster studies (about 28 days). Unlike firms relying on manual work or sampling, Onshore pairs AI-driven analysis with continuous intelligence and oversight to deliver more accurate credits and seamless system integration. Its goal is to turn tax departments from cost centers into growth capital drivers by unlocking billions in unclaimed or misfiled incentives for CFOs and finance teams.

Onshore names Alexis Peschiera as VP of Marketing.

Onshore names Alexis Peschiera as VP of Marketing. Onshore has named Alexis Peschiera as its new Vice President of Marketing, bringing an experienced B2B technology marketer into a leadership role at the AI and fintech software company. Peschiera announced the move in a recent career update, marking her transition to Onshore after her previous work in enterprise technology marketing. Her professional background includes product marketing and go-to-market responsibilities, with experience working across technology organizations and enterprise software. In her new role, Peschiera will take on responsibility for marketing as Onshore continues to develop its business in the technology and financial services space. The company operates in AI and fintech, with its current business activities spanning software and financial services. The appointment comes as marketing functions within B2B technology companies increasingly connect product positioning, demand generation, content, sales alignment, and customer communication. For companies operating in AI and financial technology, marketers also have to communicate increasingly technical products to business audiences while addressing evolving customer expectations around technology and automation. Peschiera's background includes product marketing work at IBM, where her responsibilities have included areas such as product strategy, positioning, messaging, and collaboration across enterprise technology teams. Her LinkedIn profile also shows experience with Software AG and broader product marketing activities. The new position adds senior marketing leadership to Onshore as the company continues building its presence in the AI and financial services technology market. Onshore's current hiring activity also includes marketing and growth-related roles, including a Growth Marketing Lead position focused on demand generation, content, campaigns, and marketing operations. Peschiera's appointment therefore comes at a time when B2B technology companies are placing greater emphasis on connecting marketing strategy with product development, sales, and measurable growth. Her experience across enterprise technology and product marketing brings that background into her new leadership role at Onshore.
