A personalised print business, built from the image up

Giant Sparrows was a vertically integrated print-on-demand business. People turned their own Instagram and Facebook photos, or licensed artwork, into high-end phone cases we printed in a Brixton workshop and shipped worldwide. I co-founded it, built the technology, took it to profit, and sold it in 2017.

In a nutshell

Two of my co-founders were artists; I built the technology. Together we made it genuinely easy to take an image you loved, your own photo or a licensed piece of art, and turn it into a beautifully made physical object. We owned the whole value chain: the design experience, the image ingestion, the printing, the packaging and the global fulfilment, all from a single workshop in Brixton.

The personalisation side found product-market fit fastest, and because we were early with a high quality product, we grew quickly on low acquisition costs. Then the wall arrived. Larger competitors entered the category, offered a worse experience and product, and simply outspent us. What saved the business was something we never planned: Content owners like the British Museum and Tate Modern asked us to fulfil their content for their own retail channels. That trade line grew to 60% of revenue and provided a beach head as we grew our consumer offering.

We sold in 2017 to a Scottish print company. It was a good outcome and a formative one. The lesson I carried out of it was about defensibility.

01 · Context

Two trends converging

Giant Sparrows sat at the intersection of two things happening at once in 2014. The first was the high-end mobile accessory market, which was exploding on the back of the iPhone. People had started spending real money to protect and personalise a device they carried everywhere. The second was social imagery: Instagram and Facebook had turned everyone into a photographer, and, crucially, both had opened up API access. For the first time you could reach into someone's own camera roll, with their permission, and do something with it.

The gap in the middle was the interesting part. People were sitting on thousands of images that meant something to them and the mobile phone was a blank canvas. We set out to offer a product that felt high quality and personal: take an image you care about, and make something you would actually want to own or gift.

02 · What we built

A vertically integrated print-on-demand business

We built the end-to-end service ourselves, front end through to fulfilment. The quality of the end product depended on controlling every step, and the margins allowed us higher acquisition costs. There were two content offerings.

Personalisation

Turn your own photos into something you'd keep

Connect an Instagram or Facebook account, and our custom-built design UI let you make a single photo, a collage, or whatever layout you wanted, and see it as a finished case. The whole point was to shorten the distance between "an image I love" and "a beautiful thing in my hand" to as few steps as possible. This became by far the most popular part of the business.

We licensed the highest-quality dye-sublimation system for polycarbonate and sourced the cases from Asia. Everything else, the front end, the backend, the ingestion, the packaging and fulfilment, we built and ran ourselves.

03 · Finding the market

Personalisation won, and it grew quickly

We had a hypothesis about which door people would come through, and the market corrected it quickly. The licensed marketplace was admired; the personalisation product was what drove the numbers. Being able to put your own photos onto a genuinely high-quality case, easily, was a differentiator.

And it grew exceptionally quickly. Three things compounded: the product itself was good enough that customers told other people about it, we were early to the segment so paid search was still cheap, and that early start let us build strong organic rankings. The reviews were the part I was proudest of. People do not write warm reviews about a phone case unless the object genuinely delighted them when they opened the box.

04 · The wall, and the pivot

Sat on by an 800lb gorilla

About a year in, our defensibility turned out to be far thinner than I had assumed. Competitors, PhotoBox among them, entered the category and started rapidly increasing their paid spend.

Frankly, they offered a worse personalisation experience, but it did not matter. They brought marketing muscle and brand presence we could not match, and our growth in the personalisation space plateaued. I had believed a better product was the moat. It was not. That is a lesson I have not forgotten.

What rescued us came from a direction we had never planned for. Content owners started approaching us: the British Museum, Tate Modern, textile designers and artists who wanted a really high-quality product made with their content, to sell through their own channels and physical retail. The marketplace work had proven we could hit that bar. This trade business was higher-volume, and it grew to 60% of revenue. It is what carried us into profit.

05 · What worked, what didn't, what I learned

Where you start is not where you end

The hardest part was not commercial. Three years in we had a profitable business earning good revenue. It just was not the business my co-founders had set out to build. When a Scottish print company approached us, selling was the right call, and we all went our separate ways proud of what we had made.

✓ Vertical integration paid off

Owning the whole value chain, from the digital personalisation experience to our branded box landing on the doorstep, is what helped us deliver a quality product with high margins. Our cost base was instrumental in helping us to pivot when we needed to.

↻ The product was not the moat

I assumed our experience and quality made us defensible. A worse competitor with a bigger budget proved otherwise inside a year. Distribution and brand were the real moat, and I had underweighted both. It is the first question I now ask of any consumer business.

Bootstrapping a start-up is hard, building a consumer brand from scratch is even harder. By the end of three years we were all exhausted.

✓ Diversification and resilience

The pivot to producing for content owners came from adapting to market conditions. The marketplace work had earned us credibility with serious institutions, and when they asked, we were ready. Our trade relationships became genuine partnerships over the years.

↻ Building something personal is its own reward

Giant Sparrows was a highly personal endeavour. My co-founders created a beautiful website and curated amazing content for the marketplace, which supported a roster of artists through royalties. Our custom case builder allowed people to create highly personal items and gifts, and it was lovely to see the joy reflected back in the reviews.
