Big news 📰 - We've partnered with SeedLegals to simplify FP&A for startups
From Spreadsheet Chaos to Investor-Ready & Money in the Bank
For early-stage founders in fast-moving industries like healthtech, the biggest challenge often isn’t the idea - it’s turning ambition into structure. As Genwell began shaping its pioneering, doctor-led weight loss platform, co-founder and CEO Jason Keane knew they needed a financial model that could match the pace of their innovation.
We caught up with Jason to learn how Genwell used Blox to replace spreadsheet chaos with clarity, confidence, and control - and how it’s helping them stay investor-ready as they prepare for the next stage of growth.
Genwell is a people-centred medical weight loss service built on doctor-led care and long-term wellbeing. Founded by Jason Keane and Dr. Kartik Modha, the platform connects people with trusted GPs who provide personalised, clinically safe guidance for sustainable results.
Backed by a community of over 9,500 UK-registered doctors and more than 100 GP investors, Genwell’s vision extends beyond weight loss to enable sustainable, generational wellbeing through thoughtful, empowering healthcare.

“Our goal is to take the best of medical science and make it accessible in a human, supportive way. The idea is to help people achieve long-term results, not quick fixes.”
— Jason Keane, Co-founder & CEO, Genwell
In the early days, Genwell’s team faced a familiar startup challenge - endless spreadsheets that made it difficult to model growth or explain financials to investors.
“We were bootstrapped, pulling in favours, and every time we changed an assumption, the whole model broke. You’d spend more time fixing formulas than understanding the numbers,” Jason explains.
“Spreadsheet nightmare moment - I just tried to change one cell, and everything went wrong.”
As Genwell’s product, clinical operations, and funding conversations evolved, maintaining accuracy and visibility across multiple tabs became increasingly difficult. For Jason, who was leading both strategy and fundraising, the lack of a structured, transparent model created unnecessary friction.
A simple, smarter way to model with Blox
That’s when Jason turned to Blox - introduced through SeedLegals - to rebuild the company’s financial model from the ground up.
“It instantly clicked. Someone had finally built financial planning for founders like me - people who think strategically and visually, not in formulas and cell references.”
With help from the Blox team, Genwell broke down its complex model into easy-to-understand “blocks” - one for each key part of the business:
✅ Doctor referrals and delivery
✅ Patient acquisition and retention
✅ Clinical operations
✅ Revenue streams and runway
One particularly important block was the GP cost block, which tracks the doctors delivering the service. As Jason explains:
“The GP costs represent about 60% of our total operating cost. Having a separate block for this allowed me to focus on the critical part of the business without breaking the model or missing anything.”
This modular setup meant Jason could update assumptions, test scenarios, and see how they flowed through to cashflow and forecasts - all without breaking a single formula.
“It removed financial modelling anxiety. I could focus on one block at a time, tell the story, and see instantly how it affected our numbers.”

Using Blox, Genwell transformed its financial process from a static spreadsheet into a living, interactive model. The impact was immediate:
This structure helped Genwell secure over £500,000 in funding from a network of 100+ investors, giving the team confidence and credibility in every investor meeting.
“Blox helped us turn financial stress into structure. I could walk investors through the business model block by block, and it just made sense.”
With a successful raise completed, Genwell is now using Blox to prepare for its Series A in 2026 - tracking performance against forecasts and refining its model to support growth.
“We’re now moving from planning to proof, comparing real-world results to our forecasts. That’s the kind of transparency investors love.”
For Jason, the biggest difference Blox made wasn’t just operational - it was emotional.
“Not every founder is a finance expert. Blox gives you confidence and clarity, so you can spend less time buried in spreadsheets and more time building your business.”
Here’s what Genwell achieved with Blox - not just in theory, but in real numbers and real investor traction:
“Blox didn’t just help us raise capital - it helped us prove our model, stay accountable, and keep collecting investment with confidence.”
