  • Harry Howard AI

    Participated · Seed · Jun 2026

    Harry Howard AI builds an AI-native workspace that coordinates multiple specialized AI agents, persistent project memory, and a cloud-native architecture to support solo founders through idea validation, product planning, asset creation, and operations. The platform positions itself as an all-in-one digital startup team for one-person companies, aiming to replace fragmented tools with a unified workflow. Key technical elements called out include agent orchestration, persistent project memory, and integration of large language models. The company plans to use the $3.0M seed proceeds to accelerate its core infrastructure development, hire additional engineering talent, and speed feature rollouts. Harry, the CEO, stated the platform helps solo founders move from rough idea to market launch in days rather than months. The company is based in Victoria, BC.

  • Felix Health

    Participated · Series B · Apr 2023

    Felix Health delivers telehealth services that enable Canadians to obtain consultations and prescriptions for birth control, PrEP, weight loss, hair loss, erectile dysfunction, skin care, menopause, anxiety, and other mental-health needs. The company recently broadened its scope with Felix Longevity, a preventive wellness program that analyzes more than 35 biomarkers related to metabolic, vitamin, and thyroid health. Management plans to deepen its preventive-care and testing offerings and to scale its weight-loss platform ahead of expected generic GLP-1 availability in Canada by 2026. Felix reported a $150 million revenue run rate in its current fiscal year, reflecting 80% year-over-year growth. Earlier financing of C$18 million in 2023 funded the launch of more complex care categories and therapeutic services. The new capital allows Felix to continue hiring and to expand its holistic, patient-centered virtual care experience.

  • Felix

    Participated · Series B · Apr 2023

    Felix operates a digital-first, end-to-end platform that connects Canadians with healthcare practitioners via text, audio, and video and delivers prescriptions and tests discreetly to patients’ doors. The company treats conditions including erectile dysfunction, weight loss, hair loss, HIV prevention, acne, and birth control and supports ongoing follow-ups. Launched in 2019, Felix says it is Canada’s first end-to-end on-demand treatment platform and emphasizes accessibility for patients who lack timely in-person care. Felix plans to expand into new, more complex care categories and launch additional therapeutic services in 2023, backed by investments in technology, operations, and its team. Financially, Felix completed a Series B raise of CDN $18 million to accelerate growth. Operational metrics in the article cite over 540,000 registered users, more than 200% year-over-year growth since launch, and that 40% of patients are seeking an initial prescription for their health concern. Felix has launched a digital health platform that lets users request diagnoses via an online quiz, have a licensed Canadian doctor review their medical history and symptoms, and chat through a secure messaging system. Doctors can issue prescriptions that are filled and shipped by an accredited pharmacy with discreet packaging and an option for recurring delivery, typically within two days. The platform does not require appointments and does not rely exclusively on phone or video consultations. Current treatment areas include birth control, hair loss, and acne, with planned expansion into aging, wrinkles, cold sores, herpes, HIV prevention, HSDD, and smoking cessation. The company raised $750,000 in a seed financing in March to hire key staff, enhance the platform, and expand services across Canada. Felix is positioning the raise as a bridge to a Series A targeted for the second half of its 2019 fiscal year.

    Participated · Seed · Aug 2021

    Shopistry is a Canada-based e-commerce startup founded in 2019 by Jaafer Haidar and Tariq Zabian that provides a modular, API-first toolkit for brands to create personalized commerce experiences.

Founder Haidar said the company is growing its customer base but did not provide specific growth metrics and expects to share those next year.
