Gamma's biggest amplifier after word of mouth was influencer marketing done the hard, unscalable way. Instead of betting a big budget on a handful of million-follower creators (whose scripted posts feel like ads), Grant Lee personally onboarded thousands of micro-influencers, targeting 'echo chambers' of niches like educators. Because roughly 90% of reach comes from an unpredictable 10% of creators, you cast a wide net, spread budget across many, and double down on what pops.
Origin
Developed by Grant Lee at Gamma, drawing on Dunbar's number (the ~150-person trusted network) to explain the halo effect that makes micro-influencer recommendations feel like they come from a friend.
Core principles
- 01Influencer marketing is not turnkey; the founder must be deeply involved, onboarding creators like customers or teammates
- 02Big trendy creators given a script produce content that feels like an ad and wastes money
- 03Micro-influencers in niche 'echo chambers' (e.g. educators telling other educators) carry genuine trust and spread like wildfire
- 04Roughly 90% of reach comes from less than 10% of creators, and you can't predict which, so play the numbers game
- 05Influencer spend acts as an amplifier: each dollar drives additional word of mouth on top of direct results
- 06No follower minimum matters; platforms like TikTok reward useful, authentic content regardless of audience size
How to run it
- 1
Target niche echo chambers, not taste-makers
Find pockets where your product is genuinely useful and where members trust and talk to each other (e.g. teachers sharing time-saving tools over summer break), instead of chasing a few million-follower influencers.
Pro tip Let the creator tell your story in their own voice; your job is to make sure they understand the product, not to script them.
Watch out Handing a big creator a script to read immediately feels like an ad and buys no authentic connection to their audience.

Personally onboard creators like teammates
Jump on a call with each creator, walk through the product, answer questions, and brainstorm hooks so they feel like an extension of your team.
Pro tip Creators can feel whether you put in the work; if you do, they come back and post again, building a relationship over time.
- 3
Spread the budget across many, never one basket
Rather than blowing $20k on one big influencer, work with ~40 different creators across varied personas and use cases to see what works. Start with ~20-30 creators a month and scale up.
Pro tip Budget guidance of roughly $10-20k/month sustained over ~6 months; individual creators cost a few hundred to low single-digit thousands.
Watch out Putting all eggs in one basket is the surest way to fail: you miss the winning pockets and wrongly conclude influencer marketing is a waste of time.

Remove friction with an open-source brand kit
Publish your brand, voice, tone, art direction, and prompts (Gamma used brand.gamma.app) so creators can produce on-brand content without reinventing the wheel.

Measure, then double down on what pops
Track which personas and channels convert, then concentrate next month's budget there (if educators work, find more educators). Expect a power law across platforms.
Pro tip LinkedIn conversion rates ran roughly 4-5x higher than other platforms for Gamma; test widely then double down on the one or two channels that move the needle.
In the wild
Gamma targeted educators, who make slides daily and love telling other teachers about time-saving tools, especially over summer break when they gather to discuss what will help next school season. Grant onboarded creators manually, later scaling via YC company First Collab and small hungry agencies like AKG Media in the UK.
→ Over 50% of Gamma's growth stayed word of mouth, and influencer spend amplified it: one unit through influencer drove roughly 1.5 additional users on top via word of mouth.
Common mistakes
Betting big on a few million-follower creators
Large creators given a script produce ad-like posts disconnected from their lives, feel inauthentic, and waste a large budget on people who move on the next week.
Starting with too small a budget in one basket
Founders blow their whole budget on one big influencer, see it fail, and quit, when they should have spread the same money across ~40 creators to find the unpredictable winners.
Is it for you?
Best for
Prosumer/consumer or bottoms-up B2B founders willing to do unscalable manual work to build an authentic creator channel
Not ideal for
Founders wanting a turnkey, hands-off campaign or products with no natural niche community of daily users
From the transcript
“all the initial influencers I onboarded manually myself”
“You want to be able to have them tell your story but in their voice”
“finding the thousands of micro influencers that have an audience where your product maybe is actually useful”
“we call them echo chambers where if you find a pocket like educators, teachers love telling other teachers about products they love using”
“that 20k, I could actually probably work with, you know, 40 different influencers and see what actually works”
“every time we invest in influencer marketing we actually see word of mouth increase even more”
