Hi, I'm Matt
A tech founder who's lived the early-stage grind
Growth Mentality was created to offer founders the support I wish I’d had — practical, hands-on guidance from someone who has built early products, spoken to customers, and raised funding, not theory from the side lines.
My Experience:
- Led early sales for two SaaS products - Paranimo and Matchifi - generating their first £50k through early adopters.
- Pivoted the business three times using customer insight to move closer to product–market fit.
- Raised £400k+ in grants and investment
- Coached 20+ Innovate UK founders on MVP development, early adopter sales, and investment readiness.
Who I help
Pre-revenue founders
You’ve got an idea or early MVP, but no paying customers yet. I help you validate interest, run outreach and start real sales conversations.
Early revenue teams
You’ve made a few sales - mostly founder-led and need structure. I help build a simple, repeatable sales process and refine your messaging.
Founders raising funding
You have traction or pilots but need your story to land. I help refine your deck, evidence and narrative for angels, micro VCs and Innovate UK-style grants.
