Stella & Dot Founder Raises $5M for AI Marketing Startup

Estimated reading time: 5 minutes · Last updated: 14 October 2026

Jessica Herrin, founder of Stella & Dot, launched Marklo in 2025 and has raised $5 million in seed funding to build AI marketing software that helps Shopify brands decide what to promote and prepare campaigns, as first reported by Crunchbase News. Marklo stitches together sales, inventory and past marketing data from services such as Shopify, Klaviyo, Attentive, Meta and Google to show which past promotions drove results and to suggest next actions. The Burlingame, California–based startup is pre-revenue but reports more than 100 brands in pilot and plans a public release ahead of the holiday season.

Hey, no, I can’t. It’s not Fourth of July. We don’t have the inventory anymore.

Why Jessica Herrin built an AI marketing startup

Herrin’s shift from Stella & Dot to Marklo grew out of practical gaps she encountered running consumer brands. After selling and later reacquiring Stella & Dot, she concluded that opening an online storefront had become easy, but coordinating marketing across multiple systems remained difficult. That problem—data and signals spread across commerce, email and advertising platforms—drives Marklo’s core design.

Marklo gathers sales, inventory and marketing records from Shopify and services such as Klaviyo, Attentive, Meta and Google, then aligns launches, promotions and sales on a single calendar. The company uses those joined records to surface which promotions coincided with sales lifts and to propose the next products to promote, while also drafting campaign briefs and task lists for teams to review.

Herrin says the product intentionally keeps humans in the loop: suggested campaigns are reviewed and approved by people, and Marklo does not use customer data to train its own models, according to the company. That stance is central to the pitch for small and medium brands that want the efficiency of AI without surrendering control of decisions or data governance.

How Marklo works in practice for a Shopify brand

Marklo’s workflow begins with integrations. Once a brand connects Shopify and its marketing channels, Marklo places past launches, promotions and resulting sales on a single timeline so teams can see whether an uplift aligned with an email, paid ad or an organic social post. The software then scores the likely drivers of past results and factors in inventory levels before suggesting new promotions.

A retailer that used Marklo reported planning a month’s worth of marketing in a day instead of a week’s worth of meetings and spreadsheets, Herrin says. The system can draft a campaign based on a previously successful post and create the related tasks for designers and copywriters, with notifications delivered through Slack or email.

Because Marklo factors inventory and timing into its recommendations, it aims to avoid the obvious failure mode of an AI that repeats a past promotional tactic without checking whether the product or stock still exists. In one example Herrin cites, Marklo spotted a color gaining traction on social media and nominated a matching handbag the retailer had in stock but had not recently promoted.

The business plan, investors and scale challenges

Marklo is pre-revenue and plans a subscription model with usage-based add-ons once it launches publicly. The company will use the $5 million seed to hire engineers, develop the product and expand customer support, Herrin said. Forerunner Ventures led the financing, with Freestyle Capital and angel investors from Klaviyo and Shopify also participating.

Investors told Crunchbase News they backed Herrin because she has run brands at every stage and therefore understands where teams lose time and what decisions affect profitability. Kirsten Green of Forerunner said that while AI makes content production easier, the bigger opportunity is recommending what to promote and how that affects margins.

Scaling will require both tighter integrations and support processes. Marklo’s current pilot list of more than 100 brands gives it feedback, but converting pilots into paying customers depends on delivering measurable ROI and on handling integrations with services beyond Shopify and the handful named in early marketing. Those are the technical and commercial hurdles the seed round is intended to address.

Case for and against Marklo’s growth

The bottom line

Marklo packages a familiar set of integrations and AI tools around a narrowly defined problem: choosing what to promote and turning that choice into a campaign plan that factors inventory and timing. The $5 million seed led by Forerunner gives Jessica Herrin runway to hire engineers and move from pilot to paid product, but the company’s success will hinge on converting pilot users into subscribers, proving measurable ROI and maintaining integrations with the commerce and marketing platforms brands rely on. For brands that run on Shopify, Marklo promises to shorten planning cycles—but execution and retention will decide whether it becomes a staple or one more martech tool.
