When and on what basis should a startup add a second product?

Sanjit Biswas · Dec 8, 2023

The right trigger for a second product is repeated organic customer demand, and that can come very early — Samsara's second product conversations happened when product one was around $10M in revenue

Customers who loved the GPS tracking product kept asking which dash camera worked with the system and said they'd prefer it in one platform, making the platform desire clear

Toast's full product suite was not a day-one vision; it emerged over time from customer needs

You can only do so much to begin with; a customer laid out all the systems he already ran and said they all had to integrate with the point of sale, which is the restaurant's central nervous system, and partners often wouldn't work with a tiny company so Toast had to build

Empowering a frontline employee to chase a customer-observed use case can create billion-dollar product lines — ServiceNow's HR product came from a sales engineer listening to a customer.

The platform already did 99% of what was needed; the value came from listening to the customer and letting the person closest to the problem run with it.

Scope: single illustrative case

You should only expand into new products or buying personas once you are already deeply penetrated and clearly winning in the core market, and the expansion should follow where customers are already using the product

Following the customer produced better success — hundreds of customers were already using ServiceNow in unintended ways, which they then productized; and expanding before winning in ITSM would have been a distraction requiring a new selling model for buyers outside the core

Scope: required creating business units and a different selling model

Adding pay-in/merchant acquiring was a natural evolution for Airwallex because customers already using it for global payouts also needed to process payments in

They had already built payout rails and FX, and end-to-end money flow is what customers paying contractors, suppliers and tuition also require

A Duolingo dating/matching product is the most appealing of the ideas, because there are already signs of latent dating demand on the platform

The best way to build product is to capture latent demand users can't satisfy on your product today — couples have met competing on leaderboards, found each other on Facebook and married, so the behavior already exists

When going multi-product, you should choose a second product that can reuse systems already built for the first, and rebuild those systems multi-tenant to also serve the product after that

Ramp's reimbursement product reused employee identity, request/approval flows and money movement from the card product — only the money movement destination had to change

Toast's hardware/software/network platform transfers to other brick-and-mortar verticals — grocery, convenience stores, gas stations, bottle shops — because they share the same operational complexity, employee counts and revenue profile

The sales model, service model, and depth of product Toast built for restaurants apply to these adjacent categories with similar complexity

Scope: must be done gradually, one sub-vertical at a time; starting with food and beverage retail

Physics is the subject Duolingo should add next, on competency grounds rather than market size

Launching new subjects as standalone apps was a mistake; anything educational should go into the main Duolingo app as a super app

Every experience you add to a platform should raise retention and frequency of the whole; if it doesn't, it is subtracting rather than adding.

The user should discover that the new service is better because you already know them and have the network — otherwise adding services just shows off capability without translating to their experience.

A second product doesn't have to make the first better and should be independently transactable, but concentric circles matter: solving a second problem for the same buyer makes a single lead yield two productive sales conversations

Customers can buy either product alone, though they do add context to each other and most customers buy multiple; selling to the same person is far more efficient

18:51 Independently sellable product for the same buyer

Dharmesh Shah · Jun 13, 2022

Founders should put off the second product for as long as they can, but not forever

Everyone models the upside of a second product but ignores that complexity isn't incremental — it adds a whole new axis to the business, making every decision, chart and resourcing choice harder

38:07 Delay a second product as long as possible since complexity adds a new axis not an incremental cost

Dharmesh Shah · Jun 13, 2022 · hedged

Companies are better off going all-in on a second product with full commitment than running cheap experiments or MVP tests

Product investment is a self-fulfilling prophecy: if you decide you're going to conquer the category, you put the best people and resources on it and leave no obstacle in the path, which raises the odds it succeeds

39:38 Commit fully to a second product rather than cheap mvp experiments since commitment is self fulfilling

Pat Grady · Jul 8, 2024

Companies are usually better off making their existing product better than adding new product lines

Unless what you already do is head and shoulders above the alternatives in the market, you get more juice out of improving it than out of doing more things

58:16 Improve the existing product rather than add new lines unless it is already best in market

Ilir Sela · Aug 4, 2023

The right time to introduce a second product is once the first product has enough scale and a cohort of customers who have realized success with it — and it should be introduced only to those customers, not the whole base

Every customer sits at a different point in their external business life cycle and in the internal adoption curve, so a multiproduct pitch to a merchant in a market where you're barely present is intimidating while integrated merchants are ready for more

26:30 Introduce second product only once first product customers reach scale and target only that cohort

Geoff Charles · Dec 6, 2023

Most of the company should stay single-product focused until you reach real market share, while a small tech R&D team continuously builds the next product without pulling in go-to-market resources

After PMF the binding constraint is go-to-market, not tech, so marketing and sales must stay focused on product one; a small tech team can have the next product ready in your back pocket for when growth slows

Some Bolt investors and employees argued the scooter launch was a mistake because hardware is a hard business and scooters would cannibalize highly profitable short ride hailing trips at much worse margins

About 40% of ride hailing trips in these countries are under four kilometers, so the overlap with scooters is large

Car rental will long term become a multibillion-dollar category for Bolt, because incumbent rental companies deliver a poor customer experience

Nobody is happy with the old-school car rental experience, and Bolt can improve it — including by partnering with incumbents and giving them tools and operational know-how rather than operating everything itself

The right time to start a second product is when you can see your core product's growth rate flattening one to two years out — stay focused on core as long as possible, but start early because second products take 12-24 months to build and bring to market

Segment waited a long time because core was growing fast with lots of runway, but you need to be ahead of the flattening and second products take a while to hone and deliver

38:22 Start second product before core growth flattens since build takes 12 24 months

Sumeet Gajri · Jan 17, 2020

Growing via social media or traditional advertising is a poor way to build a business in a commodified market because CAC eventually becomes unsustainable

You have no control over those acquisition channels, so growth is very expensive; whereas companies selling second and third products into their own customer base have near-zero customer acquisition cost

28:03 Cross selling into the existing customer base avoids the unsustainable cac of paid social and ads in commodified markets

Des Traynor · Jul 18, 2022

Two products should only live in the same company if the combination is multiplicative rather than additive — otherwise you should start a second startup

There must be shared entities, a shared source of truth or customer record, shared workflows and UI that give both products unfair advantages from cohabitation, so you can build product B better than a stranger could and customers prefer buying it from you

17:29 Second product must be multiplicative with shared source of truth not merely additive

Des Traynor · Jul 18, 2022

For an established company, shipping a new product that doesn't meet the brand's default quality assumptions is brand-damaging, so the release must be fully resourced to match your brand posture

Customers have default expectations when they see your logo, and handing a large customer a one-feature product makes them question what they're paying for

19:51 New product launches must match brand quality expectations or risk damaging the brand

Des Traynor · Jul 18, 2022

Whether something should be a new product or just a paid upgrade to the existing platform usually turns on whether it has a distinct buyer the current product wouldn't appeal to, plus whether you have a cross-sell/upsell plan

Without a plan for the two audiences to hear about each other it just becomes an entirely separate line of business

21:14 Distinct buyer and cross sell plan determine whether a feature is a new product or a paid upgrade

Des Traynor · Jul 18, 2022

How customers currently solve the problem is a good test: if they hack it in Excel it's probably a feature, but if they already pay for a whole separate platform it can justifiably be a separate product with separate buyers

Existing willingness to buy a second tool in that space signals a standalone product market

21:55 Existing solve method excel hack vs paid platform signals feature vs product

Adding adjacent capability (e.g. analytics reports) turns you into a different kind of company with a different brand, go-to-market and engineering needs

Investing in commodity categories like skincare regimens and vitamin supplements in the early years was a massive mistake, and the belief that assortment alone wins is wrong — the right assortment wins
