• User Observation: Watch where users hit friction or get disappointing outcomes — and fix those quickly.

From Cold Start to Unicorn

The 2020 Fundraising Story

• Remote fundraising during the pandemic from London
• Pitching late at night in a cramped apartment while caring for two young children
• Early harsh investor feedback — “worst idea ever” — which sparked reflection but reinforced the need to intertwine product and growth strategy from day one.

---

Pre‑AI Beginnings

Gamma’s ethos has always centered on making content creation easy & fast.

AI’s arrival amplified this mission, enabling:

• Faster ideation
• Improved accessibility for everyday creators
• Lower intimidation, akin to the “single‑button era” of AI

---

Product Philosophy: Better Different than Better

• Avoid “incremental improvement” traps (e.g., 16:9 legacy slides)
• Use new primitives to empower non‑designers
• Balance automation + human-in-the-loop
• Begin with product core that’s fundamentally different, not just slightly improved

---

Rich & Responsive Storytelling

Grant’s observations led to innovations like:

• Responsive-by-default layouts (mobile-friendly scrolling)
• Embed richer media (websites, interactive content)
• Progressive disclosure for deeper engagement without overload

---

Vision: End-to-End Story Support & AI Avatars

Focus areas include:

• Empowering visual storytelling for non‑designers
• Assisting with public speaking anxiety via AI Avatars
• Closing the loop from ideation → first draft → refinement → feedback

---

Gamma 1.0 → 3.0 Evolution

• 1.0:
• Target innovators ("AI tourists")
• Gain novelty-driven feedback
• 2.0:
• Win early adopters
• Gather structured feature requests
• 3.0:
• Cross into mass market
• Multi-user, prosumer-to-business shift
• Address collaboration, security, privacy needs

---

API & Data Connectivity

Gamma’s API allows:

• Zapier/Make integrations
• CRM-powered personalized presentations
• Real-time meeting-to-PDF output
• Developer-friendly embedding (e.g., real estate listings as branded PDFs)

---

Growth Strategy: Word‑of‑Mouth First

Core Principle:

• Perfect the first 30 seconds of user experience before scaling marketing
• Achieved exponential organic growth without ads

Advice for Founders:

• Validate organic advocacy before pouring money into top‑of‑funnel
• Maintain laser‑focused founder-led marketing for compelling storytelling

---

Pricing Approach

• No monetization at AI launch → urgent need to build payment infrastructure
• Used familiar, frictionless pricing (anchored to ChatGPT model)
• Hit $1M ARR and profitability in 3 months, kept model for ~2 years

---

Bottom‑Up Love & Enterprise Entry

Strategy Sequence:

• Build prosumer adoption first
• Let users internally champion the product
• Introduce enterprise plans when there’s natural pull + top-down needs

---

Moats: Brand & Local Network Effects

• Internal champions turn product into default standard
• Brand recognition drives category dominance
• Virality designed via radically simple creation & sharing

---

Culture & Hiring Principles

• Mantra: Hire painfully slowly
• First 7 hires = complete MVP team → replicated DNA in later hires
• Never lower the bar — hires must excel technically & culturally
• ~25% of team as designers to ensure UI/UX leadership in AI product innovation

---

“Taste” in Product Design

• Taste = entire end-to-end experience, not just visuals
• Curated journey, effortless navigation, guaranteed excellence

---

Founder Mode

Guidelines:

• Do the job yourself before hiring, to set standards & understand nuances
• Grant personally onboarded influencers
• Learned copywriting, hooks, creator mindset — applied to marketing hires

---

Brand Stewardship

• Value: “Don’t be boring”
• Inject culture into brand expression
• Founder participation in creative assets builds authenticity

---
