What is Smile.io?

Smile.io leans on loyalty content and partner integrations to push retention

Smile.io's feed is mostly educational loyalty content aimed at DTC and mid-market brands — omnichannel loyalty, zero-party data activation, reviews-plus-rewards, and 2026 retention trends — interleaved with partner-integration co-marketing (Digioh, Judge.me) and the occasional integration launch like Smile x GoGenerosity. Publishing cadence is low and spread over months.

What is Solidus?

Solidus builds out its new admin with product properties and store credits

The visible activity is on solidus_admin, the project's next-generation admin interface, which at v0.4.0 added a product-properties create/edit flow, a store-credits show page, and order-email display. The work is steadily porting merchant-facing admin functionality into the new UI.

Smile.io leans on loyalty content and partner integrations to push retention

◆ Current state

Smile.io's feed is mostly educational loyalty content aimed at DTC and mid-market brands — omnichannel loyalty, zero-party data activation, reviews-plus-rewards, and 2026 retention trends — interleaved with partner-integration co-marketing (Digioh, Judge.me) and the occasional integration launch like Smile x GoGenerosity. Publishing cadence is low and spread over months.

◆ Where it's heading

The strategy is positioning Smile as the retention layer in a stack of best-of-breed Shopify tools, sold through integration partnerships and education rather than a steady feature drumbeat. Expect more partner integrations that pair loyalty with reviews, data, and engagement tools, and continued thought-leadership content on retention economics.

◆ Prediction

Next moves likely continue the integration-partnership pattern (pairing Smile loyalty with complementary DTC tools) alongside retention-focused content; net-new product features aren't visible in this feed.

Solidus builds out its new admin with product properties and store credits

◆ Current state

The visible activity is on solidus_admin, the project's next-generation admin interface, which at v0.4.0 added a product-properties create/edit flow, a store-credits show page, and order-email display. The work is steadily porting merchant-facing admin functionality into the new UI.

◆ Where it's heading

With only the new-admin line visible here, the direction is clear: incrementally rebuild the Solidus admin experience screen by screen toward feature parity with the legacy admin.

◆ Prediction

The next entries likely continue filling out the new admin with more merchant-management screens.
