The SaaS Podcast – AI, Growth & Product-Market Fit for SaaS Founders Episode: SaaS Product-Market Fit: Zero Code to 8-Figure ARR Host: Omer Khan | Guest: Sarah Ahmad, Co-founder of Stable Date: March 19, 2026

Episode Overview

In this episode, Omer Khan sits down with Sarah Ahmad, co-founder of Stable, the AI-powered virtual mailbox for businesses. They explore Stable’s journey from zero code MVP to $10M+ ARR, diving deep into product-market fit, validation without code, the evolution of marketing in the AI era, and the operational complexities of building a SaaS product that bridges digital and physical worlds. Sarah candidly shares missteps from her first startup, the pivots that shaped Stable, and practical advice for founders navigating today’s rapidly shifting landscape.

Key Discussion Points & Insights

1. Stable’s Origin Story & Product-Market Fit

• Sarah’s First Failed Startup: The team's pre-Stable project, Mistro, offered international benefits for remote teams but failed the COVID-era product-market fit test—even when offered free (05:04–07:10).

  • Quote: “Even looking at giving the product away for free, people still didn’t want to use it. It was just this really good opportunity for us to just learn really fast that hey, this doesn’t have arms and legs.” (06:20, Sarah)

• How Stable Was Born: Dozens of discovery interviews with founders and ops managers uncovered a recurring pain—what to do with physical business mail when remote (07:11–08:19).

• Zero-Code MVP & Validation: The first version of Stable had zero code—just a landing page, a Google Doc, onboarding Zoom calls, and a Stripe link. Early customers received manual service with their mail uploaded to Google Drive, emails handled one by one (08:19–10:38).

  • Quote: “When we launched for this one, it was immediately clear how much more market pull there was… That was really the signal of okay, there’s something here. Now let’s go back and figure how to actually offer this product.” (09:18, Sarah)

• Advice on MVP Reluctance:

  • “The first version of Stable was embarrassing… If you’re solving something that’s a worthwhile problem to be solved, people… will be okay with it not being the best polished product.” (11:18, Sarah)
  • Customer experience compensates for lack of polish—manual onboarding, above-and-beyond support. (12:00)

2. Differentiation and Standing Out in a Crowded Market

• Finding the Wedge: Stable positioned itself as the “modern player” in a legacy industry full of clunky incumbents (13:40–14:51).
  • Small details generated delight—help with the change-of-address process, Slack notifications for mail, and then deeper automations as Stable evolved.
  • “A lot of these companies have been around since the 2000s. Their software is really clunky… That really gave us the insight of there’s a really big opportunity to build a number one product in this industry.” (06:55, Sarah)

3. Early Growth: Customers, Team, and Channels

• Growth without a Growth Team: Stable grew to 1,000 customers and $1M ARR with just 6–7 people. Word-of-mouth and content (especially blogging and organic SEO at the time) drove initial traction (15:22–16:42).

• Paid Ads Hindsight: Sarah admits to under-investing in paid ads early, due to excessive micro-optimizing and not taking big enough swings (17:23–20:12).

  • Quote: “You have to take just really big swings to understand if a channel is working.” (17:24, Sarah)
  • Retroactively, they would have spent “at least thousands” over a few months saturating high-intent searches.

• Manual Processes & Scaling Operations: The first 100 customers received fully manual service—no code. Software was only written as those manual processes neared their limits, allowing for immediate iteration and focus on core needs (22:49–24:27).

  • Quote: “We hadn’t written any code—just sending photos and PDFs via email and Slack… We started writing the software as we scaled. It was all piecewise.” (22:49, Sarah)

4. Physical Operations: More than Just SaaS

• Unlike pure-software SaaS, Stable requires a robust physical mail-handling operation—partnering with coworking/logistics businesses, running their own centers, and automating mail logistics (24:27–26:03).
  • Dallas is Stable’s largest processing center, over 10,000 sq ft.
  • “For our end customer it’s a magical experience… but there’s a lot of steps and operations that goes in behind the scenes.” (25:10, Sarah)

5. AI’s Impact: Product & Go-to-Market

• In-Product: AI has enabled advanced mail automation (e.g., data extraction, routing, integrations with customer systems)—a democratization of tech that once had to be handbuilt (26:34–29:32).

  • Quote: “Now [AI’s] very smart… You can basically figure out how to provide that logic tree, take something our customers are doing, and just automate it end to end.” (27:15, Sarah)

• On Growth & Marketing: SEO is less powerful as Google’s AI overviews swallow up organic results, so Stable now doubles down on diversified content, thought leadership, partnerships, and even direct mail for outreach (29:32–30:43). Outbound email has gotten noisier.

  • “The B2B marketing playbook definitely flipped on its head in the last couple years... We have to shift toward thought leadership, just other ways to get eyeballs.” (28:44, Sarah)

6. Moat, AI Threat, and Adapting as a Leader

• Stable’s Moat: Physical logistics and network of operations are hard to replicate and currently not easily automated by AI (31:02–32:29).
• Biggest Threat: Rapid evolution of AI could shift the software workforce and customer behavior; staying ahead requires team-wide AI fluency and constant tinkering.
• Leadership Evolution: Sarah’s journey from product builder to CEO—biggest shift was the need for constant overcommunication, clarity, and transitioning from “product-building” to “company-building” as the team scaled beyond 15–20 people (34:31–36:14).
  • “People can’t read your mind… It’s really important to say what you think about things but also say it many times. One time is not enough to get through to folks.” (35:30, Sarah)

7. Challenges & Reflections

• Hardest Parts: Grit and relentless optimism are critical for pushing through fires—“you always do” get through them (33:23).
  • “It’s really just like staying positive through all of that and just like not giving up…” (33:32, Sarah)

Memorable Quotes & Notable Moments

• “The first version of Stable was embarrassing… If you’re solving something that is a worthwhile problem to be solved, people… will be okay with it not being provided in just like the best polished product.” (11:18, Sarah)
• “We hadn’t written any code and just like, you know, just sending all of these basically photos and PDFs via email and Slack. Then we started writing the software.” (22:49, Sarah)
• “The B2B marketing playbook definitely flipped on its head in the last couple of years… What we saw last year, with AI overviews in Google Search really taking over… people weren’t clicking down even into [our blog posts].” (28:44, Sarah)
