Customer.io offers limitless possibilities, and Mavlers ensures you have the bandwidth to capture them all-turning your most ambitious ideas into live, revenue-generating workflows.

Why teams work with us: We've built 500+ automation workflows across Customer.io, Braze, Klaviyo, and Salesforce Marketing Cloud.

stitch
We stitch data, advertising and marketing technology together to drive measurable business outcomes. Marketing is more complex than it’s ever been The increase in diversity of consumption from fragmented experiences that go across device, browsers, apps and physical experiences are leading to marketing complexity where requirements are outpacing available resource while providing real challenges within the measurement space as well. Today we are exposed to more than 5,000 ads per day, yet 91% of people who could buy your product will never click on your ads (they still view it). E-commerce is growing fast, yet 94% of transactions still happen in the real world. To get full visibility into the customer journey - we need to close the loop with customer data while reducing our reliance on proxy metrics such clicks. Why choose us? At stitch we have over 30 years of combined strategic, technical and implementation experience from global tech companies, agencies and consultancies (such as Facebook, Microsoft, Accenture, Initiative Media, Clemenger & Colenso BBDO) helping brands fully realise the potential of merging strategy, data, advertising and marketing technology to deliver more profitable business outcomes through a transformed customer experience.

Brightlabs
Are you a meditation teacher? Do you want an app to easily distribute and monetize your content? After the 10th person asked me (Toby) to build a meditation app for them, I decided to launch Brightlabs. We basically white-label Brightmind (my meditation app), and set you up with a state-of-the-art mobile subscription app that you can customize however you want. Over the last decade, we’ve refined our tech stack so your app will run smoothly on all devices, and you can add content with the click of a button. Here’s a full breakdown of what you’ll get * White label-app with custom branding * User onboarding * Content library * Gamification * Timer * Favoriting * Offline functionality * Reminders * As we add features to Brightmind, you’ll get them * If you want custom app features, we can build them * Update content easily at anytime * Fully scalable (even if millions of people download in a day, nothing will break) * 24/7 bug fixes * With a click of a button, we can deploy an app update to both iOS and Android * Email and push notification systems * Analytics * A/B testing * Automated crash reporting Revenue Apple’s App Store, by gross revenue, is now bigger than 90% of Fortune 500 companies. Let that sink in for a moment. People are used to buying subscriptions on their phones for content that they find valuable. The fact that Apple and Google already have their credit card information makes purchasing as easy as a thumbprint or Face ID. Launching a mobile app is one of the best ways to get paid for your hard work.
