Growth that makes sense.
Heyday is a SaaS suite for purpose-driven digital commerce teams. Validate before you build, go live with confidence, and keep your brand consistent even when everyone works with AI.
The smart choice and the right choice are often the same choice.
Commerce teams want to grow, but get stuck in technical complexity, fragmented tooling and risky go-lives. At the same time, pressure to operate responsibly is growing: from customers, from regulations, from their own ambitions.
Better product information reduces returns and increases margins. Honest design builds trust and lifetime value. Safe launches prevent revenue loss. That is not a trade-off between growth and responsibility. That is growth that makes sense.
Heyday is not another tool on the pile. It is an integrated environment that fits how modern commerce teams work: validate faster, launch more safely, communicate more consistently.
The three products stand alone. Together they form a chain from validate to create to launch. This touches all three layers of what we call intelligent commerce: intelligent by design, honest by default, impactful by outcome.
Validate before you build.
An AI platform to test content, campaigns and ideas with a virtual target audience. Personas based on psychology and current market data. No panel, no three-week wait.
- Audience research in minutes, not weeks Present a new product page, campaign or claim, and get immediate qualitative feedback from representative personas.
- Write from your customer, not from your brand Personas point out the mismatch between expectation and reality. Fewer returns, higher margins.
- Understand the why behind your A/B test Variant B wins, but why? Audiences returns the qualitative story behind the numbers.
- Test new markets without investing first Simulate a German, Flemish or B2B audience and validate concepts before you go to market.
Create fast, with confidence.
Lock in your brand as a living digital system instead of a static PDF. Everyone on your team generates on-brand content within guardrails, with confidence that tone, claims and ethical limits are correct.
- Generate on-brand content in seconds Dedicated chat interface plus API layer for LLMs. Marketing, customer service and the German office all write in the same voice.
- Make your brand machine-readable Voice, strategy and boundaries become rules any LLM can follow. One source of truth for brand and AI.
- Stop the sprawl of individual AI subscriptions Central access to generation, with monitoring and traceability. Economies of scale instead of departments each going their own way.
- Ready for the EU AI Act Guardrails check every output for tone, factual claims and ethical limits, before publication. Compliance is a by-product.
Voice
Launch with confidence.
Roll out new functionality to real users in phases and measure the real-time impact on conversion, returns and checkout failures. Canary releasing, built for commerce.
- No more bad deploys on Fridays Start at 5% of your traffic, measure impact on your key metrics, and only scale up when the numbers are stable.
- Works where A/B tests stop A complete checkout overhaul, a new search filter or a new PDP: changes that are too big for A/B tests.
- Decide on data, not on complaints Version-level monitoring shows whether a release is truly better. Continue, pause or roll back: evidence-based.
- One-click rollback If you see a metric deteriorating, you roll back before it costs you your weekend. No manual hotfix deploy.
Built for purpose-driven commerce teams.
Heyday is valuable for digital commerce teams who want to make a positive impact and grow revenue, conversion and customer value. Four roles where work is already under pressure today, and where Heyday makes it lighter.
You make daily decisions about content, releases and campaigns without the time or budget for a study per decision. Heyday gives you validation in minutes, and releases without unnecessary risk.
Audiences Preflight BrandHubYou know what a good message is. What you miss: quick validation of whether a new campaign resonates, and certainty that AI content stays on-brand when you scale.
Audiences BrandHubEveryone in your organisation generates content with AI. Without central guidance, brand consistency becomes the biggest risk, not the biggest opportunity. One viral mistake is hard to undo.
BrandHubYour team barely dares major releases anymore. Black Friday is approaching, and staging doesn't behave like production. You want to measure impact per version, and be able to roll back without panic.
PreflightStart free, scale with your usage.
Audiences is available immediately with a seven-day trial. BrandHub and Preflight start with a consultation. As a private beta participant, you get free access in exchange for feedback.

Heyday is made by Bluebird Day.
Bluebird Day is a Dutch software studio building digital commerce for brands that take it seriously: D2C, B2B and franchise. We have been building platforms, PIM implementations and CRO projects for our clients for years.
Heyday is our tooling layer on top of that work. The products stand alone, but reinforce everything we do for clients. One suite, one login, one design language.
Learn more about Bluebird DayThe suite is built for commerce teams that want to use AI but don't yet know how to do so responsibly. You don't need an AI strategy to get started.
Heyday works for small and larger teams. Teams that need to do a lot with limited capacity get the most out of it: validate faster, launch more safely and communicate more consistently without needing extra people.
No. Each product stands on its own and delivers direct value without the other two. Many teams start with Heyday Audiences because that has the lowest barrier, and expand later to Heyday Preflight or Heyday BrandHub.
You start with a free trial period of 7 days, enough to experience the value. After that you pay a monthly amount based on the plan that suits you. There is no minimum term; you decide when to scale up or down.
We make all costs transparent in advance, including any implementation costs. No surprises afterwards.
Heyday Audiences and Heyday BrandHub are directly usable without technical intervention. Heyday Preflight requires a connection to your platform and needs one-time IT involvement. We guide that process step by step.
Heyday BrandHub can be connected via API to tools your team already uses, such as your PIM or CMS. Heyday Preflight works with Adobe Commerce and Shopware. Shopify is not yet supported.
Heyday is developed by Bluebird Day, part of Handpicked Agencies. We build the products together with other Handpicked labels and with launching customers who look on from practice. Further development is a continuous process, not a one-time project.
We only process the data needed to make the products work. The products are designed with the GDPR as the starting point and we take into account the requirements of the EU AI Act. For organisations with specific compliance requirements we enter into a data processing agreement.
You can always export your data. How this works and which retention periods apply is stated in the data processing agreement available on request. Questions about data processing we are happy to answer personally.
The private beta is invite-only. You get personal onboarding, direct access to the team and free use in exchange for feedback. We work with a limited group so we can guide everyone intensively.
We actively collect feedback from participants and translate that into the roadmap. Your input counts more heavily in this phase than later. You can sign up via the form at the bottom of this page. We will let you know within a week whether we can offer you a spot.
