Affiliate Playbook for SaaS Founders

SUMMARY

Emma Gibney, CEO of Rewardful, shares spicy takes on AI coding, SaaS growth pains, and affiliate marketing strategies for founders in a podcast interview.

CORE INFORMATION

Emma Gibney kicks off with a spicy take on "vibe coding," describing it as indiscriminately using AI for coding, which he sees as dangerous in the short term despite his own reliance as a hobbyist developer. He argues AI tools for coding are overrated now but will be underrated long-term, citing examples like Peter Levels' flight simulator project where poor architecture led to scalability issues and hacking vulnerabilities. Another case involves a developer charging $1,000/hour to fix vibe-coded messes, likening it to selling picks and shovels in a gold rush. Gibney emphasizes the spectrum of AI assistance in coding but warns of short-term pitfalls like unmaintainable code, drawing from Twitter anecdotes of real-world failures.

Rewardful, founded in 2018 by Brady Cassidy and Kyle Fox as a side project to solve affiliate tracking for recurring billing SaaS (especially Stripe-powered), grew from personal networks in the indie hacker community. Initially bootstrapped via word-of-mouth and their own affiliate program, it expanded to 2,600 customers through Google search ads, organic search, and recent organic/paid social efforts. Gibney joined three years ago when there were four employees, taking over as CEO after the founders sold and left in late 2022. Now at 12 employees (with a 13th starting), they've navigated growth by shifting from fully async remote work to adding processes like all-hands calls and standups, adapting to larger venture-backed customers with nine-figure funding and massive data volumes that strain servers.

Growth pains include scaling systems for bigger clients, evolving customer needs from indie hackers to enterprises requiring compliance like GDPR and SOC 2, and implementing management layers. Gibney describes using Phil Libin's "rule of 3 and 10," where tripling team size (e.g., 3 to 10, 10 to 30) breaks operations, necessitating operational overhauls. He also references the "invisible asymptote" concept from Andrew Chen or Eugene Wei, where growth plateaus at inflection points around $1.5-2M ARR, forcing reinvention in team, go-to-market, or product. For management, Rewardful added layers early in development (pre-Gibney), then marketing and customer success around a year later, with Gibney now managing four direct reports including heads of engineering, marketing, and customer success to leverage expertise and avoid overload.

MEMO

The Perils of Vibe Coding and AI in SaaS Development

In a candid podcast interview, Emma Gibney, CEO of affiliate tracking platform Rewardful, delivers a provocative take on "vibe coding"—the practice of blindly relying on AI for software development. As a self-admitted hobbyist developer, Gibney warns that while AI tools promise efficiency, their short-term overuse leads to architectural disasters, scalability nightmares, and even security vulnerabilities. He cites indie developer Peter Levels' AI-built flight simulator, which cornered itself into unfixable issues, and emerging "fixer" services charging $1,000 per hour to untangle the mess. Yet, Gibney remains optimistic long-term, predicting AI will revolutionize coding once refined, urging founders to treat it as a spectrum rather than a crutch.

Rewardful's Journey from Side Project to Enterprise Powerhouse

Founded in 2018 by Canadian duo Brady Cassidy and Kyle Fox to address gaps in affiliate tools for recurring SaaS billing—especially Stripe integrations—Rewardful began as a side hustle born from their own frustrations with e-commerce-focused alternatives. Early growth stemmed from indie hacker networks and word-of-mouth, amplified by the platform's own affiliate program. Gibney joined in spring 2022 with just four employees, assuming CEO duties post-founders' exit later that year. By March 2025, the team had expanded to 12 (soon 13), hitting 2,600 customers through a blend of organic search, Google ads, and paid social. This evolution mirrors broader SaaS challenges: shifting from scrappy indie users to venture-backed giants generating massive data loads that once overwhelmed servers.

Navigating Growth Pains and Scaling Imperatives

Gibney details the "growing pains" of tripling team size, invoking Phil Libin's "rule of 3 and 10," where every expansion—from solo to three, three to 10, or 10 to 30—shatters existing operations, demanding new processes like all-hands meetings over pure async Slack chats. He also draws on the "invisible asymptote" concept, where exponential growth flattens around $1.5-2 million ARR, necessitating reinventions in team structure, go-to-market tactics, or product features. Management layers emerged early in development, followed by marketing and customer success, allowing Gibney—a self-described generalist—to oversee heads of departments rather than micromanage 12 individuals. This structure fosters expertise while scaling, though it introduces necessary bureaucracy.

Moving Upmarket: Compliance, Sales, and Pricing Strategies

Larger customers arrived organically via security questionnaires and GDPR requests, pulling Rewardful into enterprise territory without deliberate chasing. Gibney opted to build robust compliance programs, hiring consultants for GDPR and eyeing SOC 2 certification, crucial for data-sensitive tools like affiliate trackers handling payments. Initially product-led, the company now embraces demos and outbound "whale-hunting" to replicate top clients, recognizing lower activation rates in this niche due to revenue dependencies. Pricing overhauls enforced tiers on underpaying high-flyers—from $79 to $499 monthly—signaling sophistication and deterring mismatches, as low tiers scream "not enterprise-ready." Power laws dominate: top affiliates and customers drive outsized value, favoring proactive servicing over broad inbound traps.

Mastering Affiliate Marketing for SaaS Founders

Gibney demystifies affiliate programs as "hard mode" for day-one launches without product-market fit, recommending they follow initial channels like organic social or Reddit engagement. Success stories, like Cometly's $54,000 MRR launch week via a dozen proprietary influencer ties, prove exceptions via pre-built relationships—think ConvertKit's equity deal with Pat Flynn. Post-PMF, passive recruitment via footers and autoresponders builds collateral like media kits and rules against PPC cannibalization or coupon sites. Active strategies involve cold outreach to niche influencers, SEO-paired listicles (with upfront payments for high-effort content), and avoiding mercenary marketplaces. Ultimately, affiliates rent trusted distribution but demand incrementality focus; Rewardful's free academy course equips founders with 12 lessons to implement effectively.
