We are still in early stages of building out our infrastructure which means you have the opportunity to play a key role in shaping what we build and how we build it
Working on ensuring a world-class, scalable back-end infrastructure
Working daily with the team to move us toward our next goal
Rapidly shipping features to users and to our internal team
Continuously evaluating our code, infrastructure, and processes to see if they meet our needs, always looking for ways to improve

Salary benchmarks

Our take

Company revenue and sales teams spend considerable time manually researching potential leads and customers, ascertaining if these potential clients are suffering from the problem their product is solving. Trawling through lead job descriptions and non-public financial data is a lengthy process, especially if you’re trying to infer information from them. Kernel.AI, formerly known as Momentum AI, saves revenue and sales team time with its fleet of AI Agents.

Kernel’s AI agents can be synced to Salesforce accounts to automate research into potential leads. The software maximises revenue and saves teams insurmountable time by building lists of potential customers. Growing enterprises such as GoCardless and FlatPay use Kernel to speed up their lead list.

The AI sales agents market was valued at $5.1 billion in 2024. By 2030, it’s expected to grow to $47.1 billion, indicating a lucrative space for Kernel. Launched by a founder who has already successfully launched two companies, Kernel shows plenty of promise as it builds itself up from 2023 seed funding.
