Why organizations choose us

Toptal in Action

Discover the cutting-edge benefits our clients enjoy from the global Toptal network.

Toptal accelerates Big Sur AI’s prototype, enabling $6.9M in funding and driving market growth.

Challenge: Founded by former Google executives, Big Sur AI aimed to revolutionize e-commerce with an AI-powered sales agent. To attract investors, they needed a fully functional prototype. While experts in back-end AI, they required a front-end specialist to create a seamless user interface.

Solution: Toptal quickly built a polished front-end interface that aligned with Big Sur AI’s vision, translating complex AI-powered back-end functionality into a seamless, intuitive UX. This enabled the company to present a fully functional prototype to investors on an accelerated timeline.

Outcome: By delivering a fully functional prototype in days, Toptal helped Big Sur AI cut weeks from their fundraising timeline and close $6.9M in investment. The company’s AI Sales Agent is available on Google Cloud Marketplace and is integrated with major e-commerce platforms like Shopify, Magento, and Salesforce.

[The Toptal talent] was instrumental in building the prototype and helped accelerate our time to raise funds by several weeks.
