The goal was to de-risk the investment. I needed to prove the business model was viable before we spent months building it - even if that meant scrapping the original idea for a better one

I joined Papermill at the idea stage, when it was conceived as a B2C tool to help students write academic reports more efficiently. But after running validation tests, my research proved the student market wasn't viable. I guided the team to pivot toward B2B agencies instead, resulting in a completely new product direction that secured our first paying clients.

My contribution:

  • Led the foundational research that informed the pivot from B2C to B2B.

  • Designed, prototyped, and validated two distinct product directions.

  • Built the design system and branding to support rapid experimentation.

  • Managed the user community to gather continuous feedback.

01

The Challenge

Papermill began as a solution for university students. We identified that formatting academic papers was a major headache from broken citations to layout errors and set out to fix it with an automated writing assistant.

Research & Design Approach

Overall scope:

Built a 50+ member Discord community by recruiting through university channels and student forums, creating ongoing access for rapid testing. Used JTBD interview structure to separate genuine pain from polite enthusiasm.

12

in-depth interviews

A/B tests

Key insight from initial research:

Interviews revealed that the problem was real, but the market wasn't. Students were too cost-conscious to pay for software, preferring to struggle with MS Word simply because it was free and familiar.

The Solution

What I Designed

Built a document editor focused on:

  • Clean, distraction-free interface

  • Smart referencing system (library + inline insertion)

  • Style templates based on university guidelines

  • Academic features (math, code, word counting)

Visual Direction

Tested two approaches with users. Students preferred the Formal direction—clean, trustworthy, professional.

Testing & Iterations

First iteration:

~15 bugs, referencing flow issues, responsiveness problems

Second iteration:

Down to 1 bug, 4/5 users completed tasks successfully, much improved usability

The Discovery

Here's where it got interesting. While usability improved, user feedback revealed something unexpected:

Students:

"I personally haven't had any problems with assignments... I just turn [grammar checking] off and do manual proofreading."

They liked it. They wouldn't pay for it. I proposed testing with other segments. Ran the same prototype with B2B agencies:

Agencies:

"Everything is a bit of a battle to get into format... Our 35-page wildlife survey reports take 10 days to create."

06

The Insight

Through designing and testing, I'd built a product with:

✅ Good usability (80% task success)
✅ Professional interface
✅ Features solving real problems
❌ Users who wouldn't pay

The problem wasn't the design. It was the market.

Students tolerated manual work because time was cheaper than money.

Agencies couldn't tolerate it because time was money.

07

Impact

For the business:

  • Identified market mismatch after 6 months, before 18+ months of heavy development

  • Redirected strategy toward B2B (now foundation of current API business)

  • Research contributed to UK innovation grant

For my practice:

  • Learned that good usability doesn't equal product-market fit

  • Practiced testing for willingness to pay, not just task completion

  • Proved the value of testing broadly, not just validating assumptions
