Loom, Zoom, In-Person: Best Formats for SaaS Customer Discovery Interviews
For SaaS founders, getting real insights from customer interviews is crucial. A poorly run interview yields polite, useless answers that won't help you build a great product. The way you conduct these interviews—async video, live video, or in person—changes how customers respond, the depth of their feedback, and your ability to dig deeper. Your choice depends on your SaaS's stage, who you're talking to (B2B IT managers vs. B2C app users), and what you need to learn.

The Quick Answer
For SaaS founders, use Loom for initial outreach when exploring a new B2B software idea or sharing a mobile app wireframe. Send a quick video explaining your concept and asking if they’d be open to a chat. Use Zoom for the main customer discovery interviews, especially when validating problem statements or iterating on an MVP. You need to ask follow-up questions and see their reactions. Choose in-person interviews when you need to understand complex existing workflows within an enterprise, observe how a team uses current software tools, or if you're targeting high-value C-suite executives who value face-to-face interaction.
Side-by-Side Breakdown
Loom: Typically free to $15/month for creators. These are async video messages. Best for warming up potential B2B SaaS clients or early adopters. You can share a quick demo of an early feature, a mobile app wireframe, or a landing page concept. Asking users to 'watch this 90-second video and share one thought' often gets more replies than a cold meeting invite. Downside: You can't ask questions on the spot or dig into surprising answers.
Zoom: Free (40-minute limit for individuals) to $15/month per user for businesses. This is a live video call. Ideal for detailed customer discovery with potential B2B buyers, product managers, or power users of a B2C app. You can share your screen to walk through a clickable prototype (like from Figma or Adobe XD), watch users interact with an early build, and ask 'why?' as you go. You'll hear tone and see reactions. Downside: Scheduling is a hurdle, and no-show rates for cold B2B outreach can still be 30-40%, wasting your time.
In-person: This offers the highest quality feedback, but carries a hidden cost of your time and potential travel. Best when you need to observe how a target user interacts with existing enterprise software in their actual office, or to understand complex data flows. It's also critical for securing feedback from senior executives who prefer direct engagement. Downside: Limited by location, very time-intensive for a small SaaS team, and travel expenses (flights, hotels) can add up quickly.
When to Choose Loom
Choose Loom early in your SaaS validation process. Use it to send a personalized video to potential beta users, industry influencers, or target B2B decision-makers, rather than a dry text email. A short 90-second Loom where you explain your SaaS concept, show a basic wireframe or mock-up (e.g., in Figma), and clearly state why their feedback is critical, often leads to more replies. It's also perfect for sharing a specific prototype feature or a new mobile app onboarding flow and asking for recorded feedback without needing to schedule a live call. This asynchronous approach helps you gather initial reactions to your software ideas quickly.
When to Choose Zoom
Zoom is your go-to for almost all live SaaS customer discovery. This is where you validate core problem statements, test user journeys within your MVP, or dig into feature priorities for your next sprint. The live format is crucial because it lets you share your screen to demo an early software build or a competitor's product and watch their real-time reactions. If a potential B2B customer mentions a surprising workflow or a critical integration need, you can immediately ask 'Tell me more about that.' Always record these sessions (with permission) and use services like Otter.ai or Google Meet's transcription to capture every detail. Both what B2B users say and how they say it about your software are valuable data.
When to Choose In-Person
For SaaS, choose in-person interviews when your software needs to integrate deeply into a client's existing physical or digital workflow. This is key for enterprise SaaS. Watching an IT manager navigate their current CRM, or observing how a team actually handles data entry in their office environment, can reveal bottlenecks or integration points no Zoom call would uncover. In-person also builds significant trust, which is often essential for closing high-value B2B enterprise deals. Lastly, senior executives in larger companies are far more likely to grant an in-person meeting than respond to a cold Zoom invite, signaling seriousness and building a relationship from the start.
The Verdict
For most SaaS founders aiming for product-market fit, the best approach for customer discovery involves a clear sequence. First, send a Loom video to warm up potential users or B2B decision-makers, offering a glimpse of your software vision and earning their interest. Next, conduct a focused 30-minute Zoom conversation, using frameworks like "The Mom Test" to avoid pitching and truly understand their pain points. Always record and transcribe these sessions using tools like Otter.ai or Happy Scribe to capture every detail for your product roadmap. In-person interviews are a powerful bonus, especially for high-value enterprise clients or complex workflow analysis, if logistics and budget allow.
How to Get Started
To start your SaaS customer discovery, record a direct 90-second Loom video. In it, introduce yourself, briefly show a sketch or early UI of your software idea, and clearly state what specific problem you're trying to solve. Send this video to 10 people in your target segment—perhaps IT managers on LinkedIn, specific roles in industry Slack communities, or early adopters on Product Hunt. In the video, end with one simple, specific question like, 'How do you currently handle X problem?' to make replying easy. For anyone who responds with useful input, follow up promptly with a Zoom calendar link to schedule a deeper discovery conversation.

FREQUENTLY ASKED QUESTIONS
Should I record my customer interviews?
Always, with permission. Recordings let you review what you missed in the moment, share key clips with co-founders or advisors, and build a library of customer language you can use in your marketing.
How do I get people to agree to an interview?
Lead with curiosity, not pitch. Say: 'I am researching how [their type of business] handles [problem area]. I am not selling anything. Would you spend 20 minutes telling me about your current process?' Most people agree when the ask is genuinely about them.
How many interviews do I need?
After 5 interviews you will start hearing patterns. After 10–15 you will hear most of what there is to hear in that segment. Aim for 10 minimum before drawing conclusions.
