I’ve had the pleasure of talking at TCV’s Have interaction Summit the previous two years. The Summit gathered ~40 CPOs and product leaders to speak by means of subjects centered round product growth and product-led progress. This yr, subjects ranged broadly from incorporating AI to ship world-class shopper experiences to defining and measuring completely different types of community-powered progress. I by no means posted my speak from final yr, so I’m adapting it right into a weblog put up right here, and can do the identical for this yr’s speak within the following weeks and in addition to some observe up questions from the Summit I’ve had an opportunity to ruminate on.

Additionally, I publish on Substack now! So subscribe right here.

After product/market match, most corporations’ obsession just isn’t enthusiastic about learn how to create their subsequent superb product. Their obsession is considering progress. Particularly, how do I get this product I do know is effective within the arms of everybody it may be worthwhile to. Most corporations have a major acquisition loop that drives this scalable progress, and sadly, there aren’t that many acquisition loops that actually scale. Even after they scale, they finally asymptote, and firms want to seek out new methods to develop. This may be new progress loops for a similar product, or completely new merchandise. On this put up, I’ll clarify how to consider the timing of that, and present a few of the successes and failures of my profession.

As I’ve mentioned in earlier essays, product/market match could be laborious to interpret on the time. Once you discover product/market match, issues don’t go away. Clients don’t cease complaining. The truth is, they complain extra, as a result of they just like the product sufficient to care. What they cease doing is leaving. And also you begin with the ability to purchase extra of them in a scalable manner i.e. an acquisition loop.

Due to this and different elements, whenever you discover product/market match, you possibly can’t cease iterating. Product/market match has a constructive slope. If you happen to discover product/market match and don’t proceed to make the product higher, a rising aggressive panorama and buyer expectations can have you ever fall out of product/market match over time. However whenever you do obtain product/market match, when you don’t cease iterating, your portfolio of what you’re employed on wants to vary.

At Reforge, we speak concerning the 4 forms of product work. As soon as you discover product/market match, zero to at least one product/market match work goes away completely for some time as your portfolio shifts to several types of product work:

  • Options: enhance present product/market match
  • Development: connecting extra individuals to present product/market match
  • Scaling: with the ability to scale the product to extra customers and extra groups internally
  • Product/Market Match Growth: new segments, markets, and finally merchandise


The expansion work particularly turns into a serious focus, strengthening and discovering new acquisition and engagement loops. Most corporations after they discover product/market match with their first product solely have one acquisition and engagement loop that’s profitable, and the job of a lot of the staff is to refine and scale these loops. At Pinterest, I used to be initially in command of constructing a brand new acquisition loop constructed on prime of Google. It appeared like this:

We finally re-architected our engagement loops to be based mostly round personalization as a substitute of round pals. Once you sew these acquisition loops and engagement loops collectively, it creates a extra sophisticated progress mannequin that appears like this:

The acquisition loop now feeds new customers right into a personalization loop that will increase engagement over time, and emails and notifications reinforce that loop by distributing related content material to customers exterior the product to convey them again. Everything of Pinterest for the primary few years I used to be there was tuning these loops in a method or one other. Ultimately, the corporate wanted to layer in new advertiser centered loops to monetize, however I’ll skip that element for now.

Once I arrived at Eventbrite, the corporate was much more mature than after I began at Pinterest. However much like Pinterest, it began with one acquisition and engagement loop driving its progress.

Creators market their occasions to herald new ticket patrons. A lot of these ticket patrons, as soon as launched to Eventbrite, begin creating occasions themselves. And when occasion creators are profitable at promoting tickets, they arrive again and create extra occasions. However Eventbrite didn’t cease there. It stored investing in making its general progress mannequin stronger.

Why did they do that? Nicely, all progress loops finally asymptote. If you happen to get good at modeling your loops, which mainly takes the diagrams above and turns them into spreadsheet based mostly forecasts of the influence to what you are promoting, you can begin to foretell when they’ll cease driving the expansion the corporate wants. Modeling each helps you are expecting when these asymptotes will occur and unconstrain these loops by discovering their bottlenecks and assuaging them. At Pinterest, we 5x’d conversion fee into signup over time, and doubled the activation fee of signups to engaged customers over time as a few examples.

Some constraints in your progress loops can’t be essentially unconstrained by optimization although. The corporate requires both new progress loops or new merchandise to amass, retain, or monetize higher. Modeling your loops helps you begin investing in constructing out these new progress loops or merchandise properly upfront of whenever you want them to maintain your progress, due to course creating them takes rather more time than enhancing a present loop. We consider this as sequencing completely different S-curves of progress.

By my arrival as an advisor by 2017 and CPO by 2019 at Eventbrite, the corporate had layered on many extra acquisition loops onto its authentic loop to proceed to develop, creating a way more sophisticated progress mannequin.

Now, I do know this seems sophisticated, however all that’s actually occurring right here is Eventbrite took its monetization of ticket gross sales and re-invested all of that cash into new acquisition loops to herald extra occasion creators (gross sales, paid acquisition, content material advertising). Additionally, Eventbrite took the rising scale of occasion stock created on the platform and began distributing it themselves to drive extra ticket gross sales per occasion to locations like Google, Fb, Spotify, and its present base of thousands and thousands of people that had purchased tickets to earlier occasions.

Folks don’t speak sufficient about how a lot S-curve sequencing work went on in any respect these profitable corporations, so I needed to offer you a style of what it appeared like throughout my expertise at Grubhub, Pinterest, and Eventbrite as a result of it’s loads, and a whole lot of it didn’t work. Let’s begin with Grubhub summarizing ten years of selections that each helped and harm Grubhub because it scaled to be a public firm (+’s present up the place I feel the choice helped, and -’s the place I feel the choice harm):

  • 2004: Grubhub co-founder collects menus of Chicago neighborhood eating places, scans them, and places them on-line (+)
  • 2005: Grubhub expands to cowl all of Chicago (+)
  • 2006: Grubhub launches on-line ordering from eating places (+)
  • 2007: Grubhub optimizes gross sales mannequin and expands into second market (+)
  • 2008: Grubhub unlocks demand aspect channels and refines growth playbook (+)
    • Grubhub launches Boston and New York (+)
    • Grubhub touchdown pages for eating places that ship to X begin rating properly on Google (+)
    • Grubhub unlocks paid acquisition to drive demand (+)
  • 2009: Grubhub scales market launch playbook (+)
    • Grubhub switches from flat price to share mannequin (+)
  • 2010: Grubhub launches pickup (-)
    • It doesn’t discover product/market match and hurts supply use instances (-)
    • Grubhub now launching no less than one new market per thirty days (+)
  • 2011: Grubhub acquires Campusfood and launches restaurant web sites (+)
    • Grubhub acquires Campusfood to develop to many school markets (+)
    • Grubhub acquires Fango to construct in-restaurant tech (+)
    • Grubhub launches restaurant web sites to drive in-restaurant progress (+)
  • 2013: Grubhub acquires Seamless (+)
  • 2014: Grubhub goes public and begins constructing a supply community to compete with Uber and Doordash (+)
    • It doesn’t matter as these corporations elevate billions of {dollars} to destroy Grubhub’s community impact (-)

What you possibly can see right here is regardless of a profitable consequence of an IPO and $7.6 billion exit, Grubhub made a whole lot of errors. If you happen to strip these errors out, the sequencing of S-curves seems like:


The principle classes that matter right here to me are that Grubhub tried product growth too early with pickup. However market growth turned a serious energy and properly oiled machine by means of gross sales and search engine marketing experience in addition to strategic M&A. That strategic M&A failed them, nonetheless, in responding to the specter of supply networks. Grubhub was integrating its largest acquisition when Doordash and Uber Eats rose to prominence, and whereas Grubhub acquired over a dozen corporations, it by no means acquired the one which was really disruptive (Doordash).

Okay, let’s do Pinterest in the identical format:

  • 2010-2011: Founder visits DIY/Craft Meetups and convinces Influencers to begin “Pin It Ahead” Marketing campaign (+)
    • This will get individuals to learn to use the “Pin It” performance of their browser (+)
    • Pinterest makes use of Fb Signal-In to bootstrap community of pals as extra individuals be a part of the platform (+)
  • 2011-2012: Pinterest leverages Fb Open Graph to share each Pin into customers’ Fb feeds (+)
    • Pinterest begins to amass sufficient content material to make discovery, not saving, major worth prop (+)
    • Retention and frequency of use enhance (+)
  • 2013: Fb turns off Open Graph and progress stops (-)
  • 2014: Pinterest fails to unlock progress with new merchandise, however does unlock Consumer Generated Content material distributed by means of search engine marketing (+)
    • Pinterest launched a maps product, a Q&A product, and a messaging product, and all fail to drive progress (-)
    • Pinterest finds one other channel in Google to distribute its top quality content material to after Open Graph turned off by Fb (+)
    • Customers are available in with much less match to present community, so buddy graph ceases to drive ongoing discovery. Retention decreases. (-)
  • 2015: Information community results kick in (+)
    • Whereas buddy graph ceases to work, Pinterest now has the size of content material to advocate nice content material simply based mostly on customers’ pursuits. Strikes to curiosity, not buddy based mostly discovery. Retention improves once more. (+)
    • Pinterest pauses all U.S. work to verify we unlock worldwide markets (+)
    • Pinterest tries to re-ignite consumer sharing and fails (-)
  • 2016: Pinterest crosses 50% worldwide energetic customers (+)
    • Focus shifts to constructing promoting enterprise to become profitable (+)
    • Development staff begins significantly experimenting with paid acquisition as new channel (+)

Regardless of Pinterest being price *verify’s right now’s inventory value* $21.5 billion on the general public markets right now, you continue to see a whole lot of the errors we made. An excessive amount of new product growth that didn’t pan out and an excessive amount of making an attempt to regain what we had misplaced vs. leaning into new areas that have been working. Community impact merchandise rely much less on new product innovation except it’s the one solution to monetize. And Pinterest tried the more durable growth earlier than the simpler ones. Market and class growth are usually a lot simpler than product worth growth. However, Pinterest did make a really profitable pivot from direct community results to knowledge community results and from Fb to Google as the first distribution channel. Once you strip the failures out, our success seems like the next sequence:

Okay, for the final one, let’s do Eventbrite:

  • 2006: Eventbrite launches to permit occasion creators to simply accept funds on-line (+)
  • 2007: Occasion creators begin placing $0 within the fee discipline to create free tickets, driving enormous consciousness (+)
  • 2008-2012: Eventbrite builds extra options to assist occasion creators run their enterprise and consists of them in ticket price (-)
  • 2012: Eventbrite builds gross sales staff to scale to extra upmarket occasion creators (-)
    • Eventbrite launches new international locations with sales-led technique (-)
    • These international locations by no means construct the self-serve progress movement of the U.S.
  • 2016: Eventbrite launches shopper vacation spot to assist shoppers discover occasions (+)
    • search engine marketing touchdown pages that includes occasions in numerous cities develop into giant drivers of ticket gross sales (+)
    • Eventbrite begins scaling emails to shoppers of occasions they is likely to be curious about (+)
  • 2017: Eventbrite launches packages and acquires Ticketfly to maneuver upmarket into the enterprise music section (-)
    • Packages makes Eventbrite extra money within the quick flip, however drive churn and fewer acquisition over time (-)
    • Many Ticketfly prospects are a poor match for Eventbrite from a service / performance perspective. Phase is low progress. (-)
  • 2018: Eventbrite acquires Picatic to construct developer platform (-)
  • 2020: Pandemic hits, and Eventbrite rewrites technique to deal with impartial, frequent creators and assist them develop
    • Concentrate on self-service and serving to creators drive demand
    • Cancel separate music product and developer platform
  • 2021: Eventbrite launches Eventbrite Increase, a collection of instruments to assist creators enhance their very own advertising
  • 2022: Eventbrite launches Eventbrite Adverts to assist occasion creators attain extra shoppers looking for occasions on Eventbrite

Since this shift is occurring in actual time, I’ll describe the S-Curve sequencing Eventbrite was investing in as of the top of my full-time function. The worth prop is shifting from funds and ticketing to serving to occasion creators develop their ticket gross sales. Eventbrite has launched new pricing with instruments like advertising instruments that assist occasion creators get higher at their very own electronic mail and efficiency advertising in addition to allow them to get extra distribution inside Eventbrite’s platform. The income from it will assist drive extra funding within the shopper product aspect of Eventbrite, which hopefully drives extra shoppers seeking to Eventbrite to seek out issues to do and shopping for extra tickets from our creators.


Hopefully you see from these examples that sequencing S-Curves to drive progress of corporations over the long run just isn’t solely fairly troublesome, however the craft of doing it’s under-developed. All three of those corporations made some crucial profitable strikes in addition to main errors that set them again years. I hope that by learning these and different examples startups can get smarter about how they sequence their S-Curves and drive long run success for his or her corporations. In my subsequent two posts, I’ll go deeper on how to consider how platform shifts like AI have an effect on this and publish much more on when and learn how to spend money on constructing your second product efficiently.

At the moment listening to my Rhythym & Bass playlist.
