Lucas and Luna examine the discipline of software testing as a strategic function, not a checkbox. Each episode focuses on a specific testing practice — from unit test coverage metrics and integration test design patterns to the economics of test automation ROI and the psychology of flaky test triage. They walk through real-world case studies: how Stripe reduced regression defects by 40% with contract testing, the trade-offs between Selenium and Cypress for e-commerce checkouts, and why Google's test size taxonomy (small/medium/large) forces better architectural decisions. Lucas explains the math behind mutation testing scores and the diminishing returns of 100% code coverage; Luna challenges him on how to sell testing budgets to skeptical product managers and when manual exploratory testing still outperforms automation. They also explore testing philosophies — shift-left vs. shift-right, risk-based testing prioritization, and the role of AI in generating test oracles. The listener lea

How to Test AI Chatbots Without Losing Your Mind
Aug 19, 202611 minS4
In this episode, Lucas and Luna tackle a question every QA team is facing in 2026: how do you test AI chatbots when the output is never the same twice? They move past the hype and get into the practical weeds — from probing a GPT-4-powered support bot with borderline prompts to automating evaluation with LLM-as-judge and golden sets. You'll hear about the 'human-in-the-loop' escape hatch that saved a fintech's customer service rollout, the metrics that actually matter (think intent accuracy, not just response time), and why your test suite should score, not just assert. If you're building or testing AI features, this episode delivers a concrete framework you can steal for your next sprint. No fluff, just the stuff that keeps AI features from breaking in front of your users. #AITesting #ChatbotQA #LLMTesting #PromptEngineering #TestAutomation #QATeam #SoftwareTesting #AIQuality #GoldenSet #LLMAsJudge #HumanInTheLoop #FintechQA #AISafety #TechPodcast #FexingoBusiness #BusinessPodcast #AIEngineering #QualityAssurance Keep every episode free: buymeacoffee.com/fexingo
How to Test Security Vulnerabilities Without a Red Team
Aug 18, 20269 minS4
Episode 159 of Software Testing with Fexingo digs into security testing for everyday QA teams. Lucas and Luna explore how a small fintech startup caught a critical authorization flaw using simple fuzzing and threat modeling — no dedicated security engineers needed. They walk through concrete techniques: mapping attack surfaces, fuzzing JSON inputs, testing for broken access control, and using OWASP ZAP for automated scans. They also discuss why security testing is a mindset, not a tool, and how to weave it into your regular regression suite. If you've ever wondered where to start with security testing, this episode gives you a practical, low-cost playbook.

How to Test Data Pipelines Without Trusting the Output
Aug 17, 20267 minS4
In this episode of Software Testing with Fexingo, Lucas and Luna tackle one of the most frustrating problems in modern data engineering: knowing whether your data pipeline is actually producing correct results. They open with a real-world story about a financial services firm that discovered a silent currency-conversion bug in its reporting pipeline — a bug that had been live for six months and had already influenced client reports. From there, they break down why traditional testing approaches fail for data pipelines, and introduce a practical framework built around data contracts, schema validation, and profiling checks that run on every batch. They walk through a concrete example using a simple e-commerce order pipeline, showing how to write expectations that catch anomalies before they reach dashboards. You'll learn how to test not just the code, but the data itself, and how to build trust in systems that otherwise look fine while quietly corrupting decisions. No fluff, just actionable techniques you can apply to your own pipelines. This episode is a must-listen for data engineers, QA professionals, and anyone who's ever stared at a dashboard and wondered if the numbers are real. #DataPipelineTesting #DataQuality #DataContracts #SchemaValidation #DataProfiling #TestAutomation #QA #SoftwareTesting #DataEngineering #ETL #BatchProcessing #AnomalyDetection #Tech #Business #FexingoBusiness #BusinessPodcast #ReliableSoftware #DataTesting Keep every episode free: buymeacoffee.com/fexingo
How to Test Accessibility Without a Dedicated QA Team
Aug 16, 20268 minS4
In this episode of Software Testing with Fexingo, Lucas and Luna explore how small teams can integrate accessibility testing into their existing QA workflows without a dedicated specialist. They break down the WCAG 2.2 criteria, the surprising cost of ignoring accessibility in both legal and user terms, and practical tools like axe-core and Lighthouse that catch issues before release. Learn why accessibility is not just a compliance checkbox but a core quality attribute, and how to make it a natural part of your testing strategy. With real-world examples and actionable advice, this episode is perfect for developers, QA engineers, and product managers looking to build more inclusive software. #AccessibilityTesting #WCAG #SoftwareTesting #QA #InclusiveDesign #AxeCore #Lighthouse #AutomatedTesting #ManualTesting #TechForGood #ProductQuality #Compliance #ADA #Section508 #DigitalInclusion #FexingoBusiness #BusinessPodcast #Technology Keep every episode free: buymeacoffee.com/fexingo
Database migrations are one of the riskiest operations in software—a botched schema change can take down a service or corrupt data. In this episode, Lucas and Luna discuss the concept of expand-and-contract migrations, using the example of splitting a users table. They explain how to test migrations in a staging environment, the role of feature flags, and why rollback strategies matter. They also touch on the importance of load testing against a copy of production data. Tune in to learn a practical approach to keeping your database changes safe and your service available. #DatabaseMigrations #SchemaChange #ExpandAndContract #TestingStrategy #RollbackPlan #FeatureFlags #DataIntegrity #StagingEnvironment #LoadTesting #ContinuousDelivery #SoftwareTesting #QA #Tech #SoftwareEngineering #FexingoBusiness #BusinessPodcast #Technology #Reliability Keep every episode free: buymeacoffee.com/fexingo
Every question we get asked before someone starts their trial.
If you have a concern about deliverability, AI quality, data privacy, or whether this will actually work for your specific situation, it's probably answered below.
What is the difference between Founder Solo and Founder Pro?
Founder Solo gives you 50 AI pitches per month using the credit model (Standard pitches cost 1 credit, Enriched pitches cost 2). Founder Pro raises that to 200 credits per month and adds full Booking Probability access, unlimited Magic Match, Apollo enrichment credits, and data export capabilities. Both plans use the same credit system, so you can stretch your monthly budget further by using Standard-mode drafting.
How do agency tiers work?
Agency tiers have no base fee. You pay per managed client and per talent profile. Agency Standard is $199 per client per month; Agency Pro is $399 per client per month. Both add $39 per talent profile per month. Your own team's user seats are always free.
What is a talent profile?
A talent profile represents one person (founder, executive, or spokesperson) you are booking onto podcasts. It includes their bio, topics, headshots, and outreach history. Team plans include 5 profiles; agency plans are pay-as-you-go.
Can I switch plans later?
Yes, at any time. Upgrades take effect immediately; downgrades apply at the end of the current billing period. Contact support if you need help migrating between plan families.
Do you offer a free trial?
Every paid plan includes a 15-day free trial. Your card is saved at signup but you will not be charged until day 16. Cancel any time from your dashboard.
What happens if I cancel?
You keep access until the end of your current billing period. No charges after that. Your data is retained for 30 days in case you reactivate.
Is the 20% annual discount automatic?
Yes. Select Annual on the pricing toggle and the discounted price is applied automatically at checkout. The annual price shown is the full year cost.
What if I have more than 50 profiles or 20 clients?
That is our Enterprise tier. Contact our sales team and we will build a custom plan with volume pricing, a dedicated account manager, and SLA guarantees.
