This week’s crowdfunding roundup has a pleasantly eclectic feel. We have a London fintech reimagining how everyday investors access physical gold, a health startup tackling alcohol dependency with clinical-grade treatment, a Cambridge agritech company growing crops in fog and an AI platform automating influencer marketing. Throw in a neurodivergent childcare companion from Italy and you have a cohort that covers a lot of ground.
What connects them is less sector and more ambition: each of these companies is going after a problem that has been underserved by existing solutions, often for a long time.
So, who are the startups crowdfunding this week? Here they are.
1. Goldwise
How much are they raising: £329,000
Website: www.goldwise.com
SEIS/EIS? Yes, EIS
About: Goldwise is a UK fintech modernising how investors access physical precious metals. Founded by former Royal Mint executives, the platform lets users buy, manage and sell fractional gold, silver, platinum and palladium through a mobile app – with institutional pricing, full LBMA-approved metal ownership and no hidden markups. That combination has historically been the exclusive preserve of institutional investors, and Goldwise is bringing it to everyone.
The dual-distribution model is the interesting part. Alongside its consumer app, Goldwise is building a Precious-Metals-as-a-Service API for wealth platforms – which means the company has both a direct-to-consumer play and a B2B infrastructure play running in parallel. Gold has delivered around 8% CAGR since 1971 and grown roughly 150% since 2019. The timing feels deliberate.

2. Nul Health
How much are they raising: £700,000
Website: www.choosenul.com
SEIS/EIS? N/A
About: Nul is building what it describes as the leading alcohol-reduction telehealth company, using medication with a mechanism similar to Ozempic. The Sinclair Method – the clinical approach at the core of Nul’s offering – has a reported 78% success rate. The company soft-launched in summer 2025 and has already reached £300,000 ARR, with 100%-plus compound monthly growth rate between July and November last year and a 55% margin.
With 27.9 million alcohol use disorder cases in the US alone and NHS-partnered trials in design, this is a large and underserved market. The convertible structure and imminent close date make this one worth looking at quickly.

3. Airponix
How much are they raising: £450,006
Website: www.airponix.com
SEIS/EIS? Yes, EIS
About: Airponix grows crops in fog. More precisely, the Cambridge-based company has developed patented soil-free fog technology that uses up to 95% less water than conventional agriculture, can be deployed almost anywhere and produces significantly higher yields from a much smaller footprint. The initial commercial focus is seed potatoes – the generation zero tubers that sit at the very start of the global potato supply chain – a market Airponix estimates at £17 billion globally.
The company has already delivered a £1.4 million commercial facility in Saudi Arabia and completed large-scale trials in both the UK and Kenya. At 92% funded with seven days left, this one is close to the line.

4. SocialTalk
How much are they raising: €450,004
Website: socialtalk.io
SEIS/EIS? N/A
About: SocialTalk is an AI operating system for influencer marketing, built on proprietary data and prediction models to automate workflows, cut manual work and improve campaign ROI. The platform is already used by brands and agencies across 25 countries and has 20,000 users. The business runs a SaaS model combined with social listening and usage-based AI add-ons, giving it multiple revenue streams.
The influencer marketing space has been notoriously difficult to measure and manage at scale. SocialTalk’s pitch is that AI can turn it into a more predictable, data-driven discipline – which, given how much brand spend flows into creator partnerships, is a commercially significant concept.

5. Oli Help
How much are they raising: €175,000
Website: www.olihelp.com
SEIS/EIS? N/A
About: Oli Help is an AI-powered companion for caregivers of neurodivergent children – parents, teachers and support workers who often have little practical guidance on how to respond to a child who thinks and processes the world differently. One in ten children is neurodivergent, and most of the adults around them are navigating it without structured support. Oli fills that gap with personalised, evidence-based guidance accessible through an app.
The platform has had 10,000-plus downloads in Italy, completed a UK clinical pilot and is reporting 7%-plus conversion and 3.8 weekly sessions per user – engagement metrics that suggest genuine utility rather than curiosity downloads. The UK scale-up is the next step, with 180 educators already in beta.
