Ex-Spotify Engineers Raise $10 Million To Bring AI Personalisation To E-Commerce

Three former Spotify engineers have raised $10 million in seed funding for Malachyte, a startup that aims to bring AI-powered personalisation to online retail.

The company was founded by Sidd Motwani, Ian Anderson and Shivaditya Sinha, who previously helped build Spotify’s recommendation technology. Their goal is to apply a similar approach to e-commerce by predicting what shoppers want in real time rather than relying on purchase history or demographic profiles.

Beyond Traditional Recommendations

Malachyte’s platform analyses browsing behaviour as customers interact with an online store, using signals such as searches, clicks, scrolling and items added to a cart to continuously refine recommendations.

According to Chief Executive Sidd Motwani, the system begins building a customer profile from the moment a page loads and becomes more accurate as the shopping session progresses. That allows retailers to personalise product rankings even for first-time visitors without requiring an account or previous purchases.

The company also considers contextual factors, such as the device being used or how a customer arrived at the website, to better understand purchasing intent.

Expansion Plans

Founded in 2024, Malachyte tested its technology with more than 20 enterprise customers across retail, travel and grocery before focusing on e-commerce.

The platform launched with Fun.com in late 2025 and has been available to Shopify merchants since June through a native integration, while larger retailers can access it via an API.

The $10 million seed round was co-led by Bessemer Venture Partners and Gradient, with participation from Harpoon Ventures. The funding will be used to expand the company’s commercial operations, strengthen product development and accelerate growth.

OpenAI Brings Unlimited Text Chats To Free ChatGPT Users

Unlimited Text Conversations Roll Out

OpenAI is removing limits on text-based conversations for all ChatGPT users, following the platform’s recent milestone of surpassing one billion weekly users.

The update introduces GPT-5.6 Luna as the default model for Free and Go users, replacing GPT-5.5.

New “Think” Button For More Complex Questions

Alongside unlimited text chats, Free and Go users will gain access to a new “Think” button, allowing them to use additional reasoning power for more complex queries.

OpenAI noted that separate usage limits will continue to apply to file uploads, image generation, voice features and other multimodal tools.

Faster Responses For Paid Subscribers

The update also brings improvements for ChatGPT Plus and Pro subscribers. They will receive access to GPT-5.6 Sol, an upgraded model designed for everyday tasks such as web research, planning, writing, decision-making and answering questions. According to OpenAI, the model delivers shorter, more robust responses.

The company noted that this version is separate from the GPT-5.6 Sol model used in Codex and Work, which remains unchanged. Plus and Pro subscribers will also receive a new thinking slider, allowing them to adjust how much reasoning the model applies before generating an answer, depending on the complexity of the task.

OpenAI Reports Fewer Errors

According to OpenAI’s internal testing, GPT-5.6 Luna produces 62% fewer factual errors than GPT-5.5 Instant, while GPT-5.6 Sol reduces factual errors by 68%.

The updated GPT-5.6 Sol model is available to Plus and Pro users starting today. The remaining features for Free and Go users will roll out throughout the week, with unlimited text chats and the new Think button becoming available next week.
