8 builders who never spoke to each other · contested

Check word of mouth exists before you build

An incentive feeds a fire already burning, it does not light one, and the arithmetic is unforgiving: under a tenth of users ever complete a referral, and the programme only works where your users personally know other potential users. The moment to launch is when you notice readers passing the thing on unprompted. What happens otherwise is documented in detail here, twice, from two builders who did the work and got nothing back.

What both sides agree on

  • Do not read early word-of-mouth demand as a working acquisition channel: a strong network fills the first few slots and then stops.

Where this splits

Jackson and Frigerio treat referral and affiliate programmes as a channel worth standing up, while Tringas built links, share buttons, popups, emails and escalating rewards and recorded no signups, clicks or shares, and Gimenez got the same nothing from a full Dropbox style scheme with happy customers.

    Only build referrals where word of mouth already runs

    Jenny Rothenberg · Jordi Giménez · Lenny Rachitsky · Paul Jarvis · Tibo Louis-Lucas · Tyler Tringas

    1. 1Only build a referral programme if word of mouth is already your main source of growth. The incentive feeds a fire that is already burning, it does not light one.
    2. 2Referrals only pay off when your users personally know other potential users, which is why they suit consumers and small business owners rather than enterprise buyers.
    3. 3Do the arithmetic on your existing user count before building anything, assuming under 10% of users will ever complete a successful referral.
    4. 4Lean hardest on referrals when using your product feels risky, because a recommendation from someone trusted is what clears that bar.
    5. 5Wait until the product already converts before launching an affiliate programme, because affiliates amplify existing growth and cannot manufacture it.

    Stand up a referral or affiliate programme anyway

    Justin Jackson · Manuel Frigerio

    1. 1Treat a referral program as the cheapest scalable way to add engaged readers, since content marketing takes a long time to repay and paid ads or sponsorships keep getting dearer.
    2. 2Set up an affiliate programme to buy referrals, and check early whether your platform lets off-the-shelf affiliate tracking work at all.

What it returned

  • 15%

    Lenny Rachitsky has not seen referrals succeed without strong existing word of mouth. Where they do work, referrals account for somewhere between 15% and 50% of new user growth.

  • Hosts on Airbnb tend to know other people with a spare home, and a Dropbox user probably has friends who would take cheap storage, but a head of HR is unlikely to know many other heads of HR.

  • With only a few thousand existing suppliers you will not produce hundreds of new ones per period through referrals.

  • The examples given are sleeping in a stranger's house and handing your dog to somebody you have only just met.
