AI has made the routine parts of marketing almost free — anyone can generate a campaign, a brief, an ad in seconds. What it can't hand you is judgement: knowing which decision is the right one, and why. That's the skill that still separates good marketers from the rest, and it's the one universities struggle to teach. Novela teaches it through simulation. Students step into realistic versions of platforms like Google Ads and Meta, run real campaigns for fictional brands, make decisions and live with the consequences — building judgement through practice instead of memorising theory. An AI copilot works alongside them, the way it will in their actual careers. And it's working. More than 50 universities use Novela today, including Columbia, Northwestern Kellogg, Oxford, Imperial and INSEAD. We're a two-founder company, profitable, and growing fast — and we're now hiring beyond the founders for the first time. The hard problems we're working on: how do you teach a skill that can only be built by doing? How do you make a simulation realistic enough that practitioners respect it and students genuinely learn from it? And how does a small team serve hundreds of professors around the world without losing the quality that got us here? If those are the kinds of problems you want to spend your time on, we'd like to meet you.

Warmo is a GTM Signal Intelligence Platform that helps B2B founders, agencies, and sales teams find high-intent prospects automatically.

Winning bids is how all governments and large organisations buy their goods over the world. These are extremely complex, time-intensive contracts that take large teams months to prepare. We're building an AI bid creation platform, where we generate final proposals, not first drafts, to reduce the time of creating bids by 75%. We value quality, simplicity and speed. Our vision is to have every business in the world, through using mytender.io, an experience where they create a proposal, something they look forward to.
