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 mission is to redefine weight loss and wellbeing through trusted medical expertise, personalised care, and a commitment to long-term results.”
— 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 had multiple sources of data feeding our financial model which led to multiple errors over time that became hugely frustrating as we were constantly trying to fix model versus progressive financial planning,” Jason explains.
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
“We had one briefing session with the Blox team who ingested our model into their system and instantly our model was clean and clear. As a strategic thinker that relates to visual cues, it enabled me to build a comprehensive model in blocks (blox) so we could define the key business growth drivers first, test assumptions and then layer in costs to determine whether the business could generate an ROI for investors.”
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:
“Clinical care was a core component of both our financial model and patient experience. Blox allowed us to quickly identify key operating costs — from clinical staff mix to product lines — and easily test or update assumptions and growth scenarios. We could instantly see how changes impacted forecasts and cashflow, all without risking a single broken formula. Every block was self-contained and enabled us to build a robust end business model.”
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 eliminated the stress typically associated with financial modelling. I was able to focus on one ‘block’ at a time, build the narrative, and instantly see how each adjustment impacted 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 enabled us to build a robust financial model, starting with key growth drivers and layering in operational costs through to projected investment returns — block by block. These modular data components were seamlessly rolled into a single, dynamic dashboard, allowing us to confidently migrate core metrics into our investor deck and ensure the Genwell narrative was both compelling and credible.”
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 an accountant. Blox gave us the financial framework and toolset to build an end-to-end business model with confidence and ultimately 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 design the UK’s first ever GP-only crowd funding round, with over 100 investors truly believing in our patient vision and underlying business model. Blox and their team were instrumental in helping us hit this major milestone and we look forward to taking this to the next stage, series A!”
