Client

A US-based startup founded by creatives who have contributed to projects for Apple, Meta, Adidas, and other global brands. Their product, Neudesk.ai, is an AI-powered document creation platform designed for freelancers and solo entrepreneurs. It helps users pitch their work more effectively, automate proposal workflows, and close deals faster.

Business Challenge

For many freelancers and small business owners, creating a professional proposal often feels more like a headache than an opportunity, especially for those working in creative industries like advertising, photography, or content production. What should take minutes often turns into hours of drafting, revising, and sending countless follow-ups to clients.

Proposals are usually built manually, scattered across different tools, and often need legal input. Despite all this effort, important details often slip through the cracks. Switching between documents and apps, rewriting the same information, and trying to keep every proposal consistent quickly drains both time and focus.

Our client wanted to change that. Their goal was to remove the chaos and replace it with a smooth, unified experience that guides users from pitch to contract signing in one seamless flow.

The challenge was to automate complex proposal creation workflows while keeping the editing and collaboration process intuitive. One standout feature requested by the client was the ability not only to display the proposal document, but also to attach vendor videos and genuine client testimonials, helping build trust from the very first interaction.

To bring this vision to life, the client partnered with Upsilon to build an MVP designed to make every part of the process smarter, faster, and more seamless.

Solution

Before development began, the client presented Upsilon’s team with a clear MVP concept, initial design, and a list of desired integrations.

Our experts analyzed these inputs and, drawing on extensive experience in AI and product development, proposed the most suitable technologies and AI tools. Together with Neudesk, we selected:

React

for the front end

Python

for the back end

LangChain

for rapid prototyping with AI

The first product version was built intentionally simple and focused on an intuitive AI document copilot. This smart editor allows users to interact with AI using prompts to create, edit, and personalize proposals and contracts in seconds.

Within one seamless workspace, users can:

Generate proposals in seconds
Personalize and
brand content
Add vendor’s videos
and testimonials
Automatically turn proposals into contracts
Share proposals
via email or link
Get feedback and approve
documents in one click

AI sits at the heart of the product, helping users draft smarter and move deals forward faster. It keeps every document well-structured, aligned with the client’s tone and goals, and ready for the next step in the sales process. It also provides dynamic suggestions for pricing, performance metrics, and quick wins, supporting users at every stage of proposal creation.

The result is a simple yet powerful platform that saves freelancers and startups hours of manual work, simplifies collaboration, and turns the entire proposal-to-contract process into one effortless experience.

Impact & Results

The new platform was launched in time and within the budget. It made proposal and contract management a much smoother experience. Instead of juggling tools or getting stuck in endless edits, users can now focus on their work and client relationships.

Here’s how the change shows up in practice:

Workflows became simpler

Everything happens in one place, from creating proposals to signing contracts.

Collaboration is
improved

Clients can leave comments, approve, and sign directly within one workspace.

Smoother communication

Fewer emails, more clarity, and faster decisions.

The AI helps users stay consistent and on-brand, guiding structure, tone, and pricing suggestions automatically.

Neudesk received an MVP ready to test with wider audiences, showing strong potential for investment and future scaling.

Working with Upsilon was a smooth and straightforward experience. The team was organized, responsive, and brought solid technical insight throughout the MVP build. They helped me evaluate options, make informed decisions, and kept development on track from start to finish. I’m happy with the result and appreciate the partnership.
