- Helcim Inc.
Participated · Series C · Aug 2026
Launched in 2020 and headquartered in Calgary, Helcim builds an end-to-end payments and software platform that includes point-of-sale, invoicing, online checkout, a smart terminal, and embedded payments tools for small and mid-sized businesses. The company reports more than 22,000 active merchants across North America, crossed CA$150 million in ARR, employs about 200 people, and is on track to process nearly CA$10 billion in annual payment volume. Helcim built its infrastructure in-house rather than reselling another processor, enabling volume-based interchange-plus pricing. In January 2026 it released an AI-powered Payment Extension to let merchants self-integrate Helcim's payments into existing software, and adoption has scaled quickly. The company intends to use its recent funding to further develop its payments platform, expand into additional financial services for merchants, and deepen partnerships with regional banks and credit unions.

- Confido
Led · Equity · Mar 2026
Confido offers an API-based platform that lets law firms and legal technology providers accept card and ACH payments, route funds between trust and operating accounts, perform intra-firm transfers, and issue real-time digital disbursements while automatically maintaining compliance with bar and IOLTA rules. Designed around the legal sector’s strict trust accounting requirements, the system replaces manual reconciliation and paper-based processes with automated, compliant money movement. The product is delivered through a single GraphQL API and one underwriting process that LegalTech vendors can embed directly into their own software. Confido currently powers payments and financial workflows for numerous LegalTech platforms and supports more than 1,500 law firms across the United States and Canada. The global legal industry moves more than $1 trillion annually, and Confido aims to consolidate its fragmented financial workflows under one compliant platform. With the new funding, the company plans to bolster its payments and disbursement infrastructure and roll out additional embedded financial products for its partners and law-firm customers.

Recent company milestones include assembling a Scientific Advisory Board comprised of leading figures in oncology screening and molecular diagnostics to guide product development and commercialization strategy. Proceeds from its latest funding are earmarked for continued clinical validation studies and preparing a commercial launch later in 2024.
