## About Ritual

## Company Overview
- **One-liner**: Ritual is a social ordering app and online ordering platform that connects local restaurants with customers, offices, and building tenants, enabling convenient order‑ahead and pickup.
- **Entity Type**: Private (funded – Seed, Series B, Series C, and later rounds; total funding $137.3M)
- **Headquarters**: Toronto, Ontario, Canada (with additional offices in the United States)
- **Founded**: 2014
- **Founders**: Ray Reddy (CEO & Co‑founder) – additional co‑founders are not publicly named in the available sources.

## Core Business
- **Primary industry**: Food technology / Consumer services (online ordering, restaurant technology, employee meal perks)
- **Target customers**: B2B (companies offering meal perks to employees, building management) and B2C (individuals ordering takeout). Secondary customers are restaurants (especially independents) wanting a low‑commission ordering channel.
- **Mission / purpose**: “We’re for restaurants and the people who love them” – helping local businesses thrive online by providing affordable technology and fostering community around food.

## Products & Services
- **Ritual App (Consumer)**: A mobile app that lets users order ahead from nearby restaurants, skip the line, and pay. Includes a unique “social ordering” feature where co‑workers can add orders to a single pickup.
- **Ritual for Restaurants**: An online ordering system that gives independent restaurants a digital presence with lower commissions than major delivery platforms.
- **Ritual for Offices & Buildings**: Meal program and tenant rewards that make it easy for companies to offer daily lunch credits, connecting office workers with local eateries.

## Market Standing
- **Valuation / Market Cap**: Not publicly disclosed.
- **Key Metric**: Annual revenue of **$30M** (latest available); total funding **$137.3M** across 5 rounds.
- **Notable Investors**: Insight Partners (led Series B), Mantella Venture Partners, Mistral Venture Partners (seed), and others.
- **Growth Signals**: Small team of ~15 employees (down ~26% YoY, indicating a lean operation); acquired AllChecked.in in 2021; presence in North America and Australia; continues to serve both consumers and enterprise meal‑perk programs.

## Competitive Advantages
- **Restaurant‑first model**: Lower commission structure compared to incumbents like DoorDash, making it more attractive for independent restaurants.
- **Social ordering moat**: The ability for co‑workers to piggyback on one order creates a network effect within offices and buildings.
- **Hybrid‑work alignment**: Office meal credits and building partnerships directly address the “return‑to‑office” trend.

## Strategic Focus
- Deepening relationships with office buildings and enterprise clients to drive recurring meal‑perk revenue.
- Continuing to offer affordable technology to independent restaurants to help them compete digitally.
- Maintaining a lean, low‑burn approach while refining its product for a post‑pandemic hybrid work environment.

## Why Work Here
- **Culture**: Values include Ownership, Impact, Open‑mindedness, and Good Judgement. The team is small (15 people) so every hire has outsized impact.
- **Work policy**: Hybrid model – weekly credits are provided when in the Toronto office, and daily credits are available on office days.
- **Perks**: Ritual Credits for meals; emphasis on work‑life balance (rating 3.6/5) and culture (3.9/5) on LinkedIn.
- **Engineering culture**: Data‑driven decision making, modern tech stack (Kubernetes, Python, Google Cloud, Snowflake, React, etc.). Previous employees have gone on to top tech companies (Shopify, Amazon, Google, Wealthsimple).
- **Career growth**: Employees rate career opportunities at 3.6/5; leadership is hands‑on due to team size.
