A streamlined proposal builder that helps agencies send polished client offers before a slow document workflow costs them momentum.
flat for a few years
“Sometimes in minutes they can send a proposal.” The practical edge is getting a clear offer to the buyer while the sales conversation is still warm.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Nusii is Michael Koper’s proposal software for agencies and consultants. It has stayed around $10K per month for several years, while a Google update reduced its search traffic and the decline persisted. Michael bought out a former cofounder who had handled more of the design and marketing; he is now the developer carrying both product and marketing. The customer base spans many industries, but marketing agencies are its largest segment and tend to stay longer than freelancers. The best-fit account described in the conversation is a small agency near twenty employees sending around ten proposals a month. Nusii’s useful product shape is a quick proposal workflow: templates, reusable sections, personalized details, proposal-view visibility, follow-up, and signing. Its challenge is positioning. Proposal software is crowded, competitors make similar claims about simplicity, and the homepage’s broad language does not show why the product is different.
Your first-customer lane should be the small marketing agency Michael described: around twenty employees, a continuing pipeline, and roughly ten proposals a month. Freelancers often cancel once work is won, so build prospecting around teams that keep selling while delivery is underway.
