- QA Wolf
Participated · Series B · Jul 2024
QA Wolf provides an outcomes-based QA testing platform that automates test creation and runs for Android, iOS, web, and Salesforce apps with humans in the loop. The company pivoted after its 2019 launch from test orchestration to selling test coverage to better align incentives and increase real-world test coverage. Customers pay a flat rate that includes test creation, unlimited parallel test runs, and 24-hour failure investigation and maintenance. QA Wolf says customers ship 2–5x more often and reduce rework by shifting testing earlier in the development cycle. The company serves over 130 customers, including Salesloft, Drata, and AutoTrader.ca, and has a roughly 130-employee workforce. QA Wolf plans to use new funding to build additional features, enhance its automation technology, and grow its team. QA Wolf builds and runs automated end-to-end tests for web applications and integrates with customers' internal systems to provide a real-time view of software performance. Clients submit a short demo of their app, and QA Wolf creates a testing plan and codes automated test suites written in Playwright so tests can be migrated if desired. The service supports web apps that use third-party services like Stripe and Salesforce and includes ongoing support for writing and maintaining tests, investigating failures, and reporting bugs. Founded in 2019 by Jon Perl, Laura Cressman and Scott Wilson, the company combines technology, a people-driven approach, and a business model aimed at delivering high-performing, accurate testing. At the time of the announcement QA Wolf had a 45-person team, more than 50 customers, expected to grow to 60 employees by year-end, and reported revenue up 25x over the past year with business doubling in the last six months. The company plans to use new funding to expand engineering, sales and marketing and to build datasets of tests across web apps to develop additional products and services.

- Wand App
Participated · Seed · Aug 2023
Wand.app is an AI-powered creative tool designed to give artists manual control over image generation through visual tools and personalization rather than relying solely on text prompts. Its illustration tool converts sketches or edits into fleshed-out suggestions, and users can teach a personal AI to replicate a specific aesthetic. Editing occurs on a freeform art board where individuals or teams iterate, and the product runs on mobile and tablet (with Apple Pencil support) and will soon arrive on desktop. The company is testing with a small group of beta users and plans a public launch in the coming months. Wand plans to build collaborative team features, extend creative tooling to desktop, research foundation model architectures and fine-tuning techniques, and explore marketplaces for artists to share or sell fine-tuned models and potential 3D modeling applications. For now it uses an in-app credit system to cover GPU costs and is considering subscription pricing similar to DALL-E 2, Midjourney and Dream Studio longer term.
