We build, back and grow SaaS and online businesses.

Aptitude is a product studio and early-stage investor. We spent years building websites and running digital campaigns for other companies. Now we put that experience, and our own capital, into SaaS and online businesses: ours, and yours.

We bring the frame, the walls and the floor. You bring the missing side.

Our campaigns have been covered by

  • Mail Online
  • Metro
  • ABC News
  • BuzzFeed

One company, three sides.

Most founders end up hiring an agency, raising from an investor and paying for growth separately. We do all three, and we have done them for our own products first.

  • Build

    We design, engineer and launch SaaS products, platforms and online stores. Strategy, UX, full-stack development and the infrastructure to run it, from first prototype to paying customers.

  • Back

    We invest early, with capital and with time. A board seat when it helps, a sounding board always, and the judgement of people who have built and run online businesses of our own.

  • Grow

    Growth is where we started. SEO, content, paid acquisition and conversion: the digital marketing playbook we ran for clients for a decade, applied to your product.

Companies we have built and backed.

We take a hands-on role in every company we are part of, from writing the code to sitting on the board.

Your company

We are looking for the next SaaS or online business to build or back. If you are a founder with an idea or an early product, we would like to hear about it.

Pitch your business

Before the ventures, the agency.

From 2009 Aptitude was a digital agency. We built content-managed websites and ran digital marketing campaigns for companies large and small, and some of that work made the national papers. Every product we build or back now gets the same craft and the same obsession with growth.

Album Covers: The Bigger Picture
Our campaign imagining famous album covers uncropped was covered by Mail Online, Metro, ABC News and BuzzFeed, and earned more than 2,000 backlinks from 300 domains in under two weeks.
Decibel Nutrition
A content campaign built on linkable infographics took average website visits from 100 to 40,000, peaking at over 80,000 unique visitors a week.
Merchello
We built Merchello, which became the largest open-source ecommerce platform for Umbraco. Ecommerce is our specialism: online stores, checkout and payments for clients, and the platform other developers built theirs on.
  • They created a lot of content for our business with some of the infographics going incredibly viral, bringing in traffic of over 80,000 unique visitors a week at one point.

    Adam Johnson Decibel Nutrition
  • They gave me advice, not just on my actual logo, but on marketing the brand and helping me think about my target market. They had my company’s best interest at heart.

    Amy Neale Mooeys
  • Great to work with. Very good understanding of our challenges and the importance to overcome them, despite the complexity of our needs.

How we work with founders.

No pitch theatre and no fixed playbook. Each partnership is shaped around the company and what it needs next.

  1. Talk

    Tell us what you are building and where you are stuck. A short call, no deck required.

  2. Dig in

    We look at the product, the market and the numbers together, and tell you honestly whether we are the right partner.

  3. Shape the deal

    Investment, a build partnership or both. We agree a structure that fits the stage of the company.

  4. Build and grow

    We work alongside you on product and growth, with the same urgency we give our own ventures.

You are raising

You have a SaaS or online business with early traction and want an investor who rolls up their sleeves. We back founders with capital, board-level support and hands-on help with product and growth.

Pitch your business

You are building

You have an idea or an early product and need a team to design and build it properly. We work as your build partner, and where it fits, we invest alongside you.
