1. Early-Stage Ventures
From idea to prototype — we help you validate before you build.
We work with founders and product teams who are just starting out — often with nothing more than an idea or wireframe. Our team conducts market research, competitive analysis, and early product ideation to answer the critical questions:
Is there a real need in the market?
Are competitors already solving this problem?
What makes your approach different or better?
We then help translate insights into product concepts that are grounded in accounting reality and positioned for success
-
2. Established Platforms Rolling Out New Features
Reduce rollout risk with independent feature testing.
For more mature products, we act as your independent QA layer, testing new features before they go live. From workflow validation to functional testing across integrations, we ensure every update lands smoothly — minimizing disruptions to existing users and preserving your brand reputation.
-
3. Ongoing QA and Validation Partners
Your outsourced QA and data validation team.
Some companies integrate Preflight Labs into their day-to-day operations. We manage ongoing quality assurance — debugging, regression testing, data validation, and continuous feedback loops with your dev team. Think of us as your QA command center, ensuring accuracy, performance, and trust in every release.
About Us
Accountants + Product Thinkers = Preflight Labs
Preflight Labs was founded by accountants and technologists who saw too many accounting apps hitting the market prematurely, before they had been stress tested by accountants. We bridge the gap between product teams and their customers.
