Sway

We create seaweed-based compostable packaging that replaces plastic while protecting oceans and ecosystems.

Sway is a material innovation company scaling home compostable, seaweed-based solutions for plastic. We've been recognized as a TIME Best Invention of 2025, a Fast Company World-Changing Idea, and winner of the TOM FORD Plastic Innovation Prize. Our technology drops into traditional plastic infrastructure while working to replenish ocean health, promote regenerative materials, and create a more inclusive environmental movement.

WHAT YOU'LL DO
Over 12 weeks, you'll help us climb Google's rankings for high-impact keywords like "seaweed packaging," "compostable packaging," and "next-generation materials." Your work will directly shape how people discover Sway and, ultimately, how they access alternatives to conventional plastics.

Phase 1 (Weeks 1-3): Audit

• Conduct a comprehensive technical SEO audit of Sway's website (site structure, performance, indexation, user experience)
• Analyze current keyword rankings and competitive positioning
• Identify content gaps and quick-win opportunities
• Deliver a clear, prioritized audit report with recommendations

Phase 2 (Weeks 3-4): Strategy & Roadmap

• Develop a strategic execution plan prioritizing high-impact opportunities
• Recommend on-page, technical, and content improvements
• Identify keyword targets aligned with Sway's business priorities
• Present findings and roadmap to our Marketing & Communications team

Phase 3 (Weeks 4-12): Implementation & Quick Wins

• Implement priority technical SEO improvements (with our team)
• Optimize existing content for target keywords
• Create content briefs for new pages
• Configure Rankmath settings and reporting dashboards
• Track KPIs and share monthly progress updates
• Identify and execute quick wins toward longer-term visibility goals

WHAT YOU'LL NEED
Essential Skills:

• 5+ years of SEO experience with proven results (rankings, organic traffic growth)
• Expertise of technical SEO (Core Web Vitals, crawlability, structured data)
• Proficiency with Google Search Console, Google Analytics 4, and competitive analysis tools (SEMrush, Ahrefs)
• Fluency in SEO for Wordpress (site structure, plugin management, performance)
• Ability to audit, strategize, and execute independently
• Clear communication with non-technical stakeholders

Desirable Skills:

• Experience with Rankmath or Semplice (platforms Sway uses within Wordpress)
• B2B or sustainability sector SEO experience
• Portfolio or case studies showing measurable SEO wins
• Interest in material science, climate tech, or sustainability

WHY THIS MATTERS
Search visibility is how the world discovers that seaweed-based alternatives exist. Every keyword you optimize, every page you improve, and every ranking we climb puts Sway closer to the brands and distributors actively looking for solutions to plastic packaging. Your work will help scale a material innovation that directly improves ocean health, our climate, and our worldwide waste problem.

SUPPORT & WHAT YOU'LL GAIN
We'll set you up for success:

• Mentorship: Direct collaboration with our Head of Marketing & Communications; access to Sway's founding team and product/R&D insights
• Feedback: Monthly check-ins, strategic guidance, and technical support as you navigate implementation
• Reference & Portfolio: This becomes a standout case study for your portfolio — measurable SEO wins at a mission-driven startup
• Impact Clarity: Monthly reports showing rankings, traffic, and business impact
• Community: You'll join the Sway team and the broader network of ChangeMakers driving climate innovation

Inshira Technologies LTD.

We help small manufacturers reduce waste, energy losses, and emissions using their existing operational data.

We are a UK startup building the intelligence layer for manufacturing. Our AI platform uses the production data SME manufacturers already have to show exactly where time, cost, materials and energy are being lost - no new sensors, no six-month IT project, results in weeks. Every factory we win takes real waste and energy out of a production line, which is the change we are here to make.

Why we need you

We know who we are selling to: SME manufacturers across the UK and Europe, and the operations managers, production directors and owners inside them. What we do not have is an experienced B2B seller to get us in front of them and convert interest into signed pilots. That is where you come in - hands on, alongside the founder.

What you will do

• Turn our target profile into a prioritised, named account list you can actually work
• Run outbound to those accounts and open doors with the right people
• Run and coach discovery calls: better questions, harder qualification, and objection handling around data access, ROI and "we already have a system"
• Work with the founder to move a small number of live opportunities toward paid pilots
• Leave behind a short, usable outreach and objection-handling playbook we can run ourselves

Deliverables

These are scoped to fit roughly 16-24 hours in total, so they are deliberately tight rather than sprawling.

1. A prioritised list of 30-50 named UK and EU SME manufacturers, with the right contact identified at each
2. One tested outbound sequence (email and LinkedIn), sent to that list, with response data
3. 5-6 qualified discovery conversations booked
4. 2-3 opportunities progressed toward a pilot, with a short written pipeline handover
5. A 2-3 page sales playbook, including a simple qualification checklist we can keep using after the engagement ends

Who we are looking for

• Proven B2B sales experience, either selling technology or SaaS at an early-stage startup, or selling into manufacturing, engineering or industrial environments. Either background works; both is a bonus.
• Comfortable with a considered, multi-stakeholder sale and a longer buying cycle
• Genuinely hands on - you will be writing outreach and joining calls, not only advising
• Confident talking about operational efficiency, waste and ROI with non-technical buyers
• Self-directed: we will give you context and then get out of your way

Nice to have

• A network in UK or EU manufacturing
• Experience selling a first product with few case studies to lean on

Time commitment and working style

2-3 hours per week for 1-2 months, fully remote and flexible. We keep it to one 30-minute sync per week plus async messages, so your time goes into selling rather than meetings. We are UK based (GMT/BST) but will work around your schedule.

Your impact

You will help a small climate-and-efficiency startup land its first paying manufacturing pilots, and walk away with a clear, attributable story of having built a B2B sales motion from close to zero.

Minimum Hours per Week:

2-3 hours per week

Duration:

1-2 months

We're looking for an experienced Fundraising Volunteers to help us find the money we need to keep our club going and grow. This is a vital role where your skills can make a real difference. You'll be working behind the scenes to find new funding opportunities, write strong applications, and help us show funders the amazing impact our club has. If you've got experience in fundraising and want to use it for a great cause, we'd love to hear from you!

The Unseen Barriers Foundation is looking for new Board Trustee's.

We are a new, disabled-led Scottish charity (status pending) tackling the invisible causes of exclusion. Shame, sensory overload, emotional exhaustion, disbelief. These are the things that stop people from showing up — to appointments, to events, to life.

The Foundation is built around two original lived experience contributions by our founder:

The Unseen Barriers Framework — a landmark conceptual model naming the distress-based barriers that keep disabled people locked out of support

Cùran — a green plush dragon created as a visual anchor for distress, shutdown, and solidarity

Both are licensed to the Foundation by the creator to ensure they serve a purpose-first, rights-based mission.

We are now looking for trustees to help shape this work from the ground up. This is a working board — not a figurehead role. Trustees will actively contribute to strategic direction, governance, and growth.

We are currently remote-first to ensure full accessibility, but will provide office space (Edinburgh/Glasgow area) once funded. You do not need to be based in either city.

Estimated time commitment:

Around 6–8 hours per month including preparation, meetings, and task-based input

Board meetings held every 6–8 weeks via Zoom

All access needs will be fully accommodated

We are especially keen to hear from:

Disabled people and unpaid carers

People with lived experience of distress, neurodivergence, or poverty

Individuals with skills in finance, charity governance, fundraising, legal oversight, or communications

If you believe in radical inclusion, and want to join something disruptive but grounded, get in touch.

We believe in finding the right people, not just filling seats. Informal conversations will take place on a rolling basis, and trustees will be appointed as and when suitable candidates are identified. Early expressions of interest are encouraged.

Use your creativity as a graphic or motion designer to help us grow our cinema's social media presence and our audience.

We're a certified B Corp and registered social enterprise at an early and exciting stage. We've run our first trial event in London and are working on building the community before we scale. This is an opportunity to shape how an emerging climate action community delivers impact.

The role

We're looking for a proactive, personable, and organised volunteer to build and manage the distribution partnerships that get Earth Steward's events in front of the right people.

This is fundamentally a business development and relationship management role. You'll be representing Earth Stewards Travel Club externally, opening doors, and building the network of partners who help us grow without paid advertising.

• Build and maintain ongoing relationships with accommodation partners, keeping them updated on upcoming events and new tour routes
• Explore reciprocal opportunities where relevant, promoting partner properties to our community in return

Tourism organisation partnerships

• Identify and approach tourism organisations, destination management organisations, sustainable travel networks, and visitor guides whose audience matches our community of eco-conscious travellers
• Pitch co-promotion arrangements: newsletter features, social media cross-promotion, event listings in partner channels, or collaborative event programming
• Develop relationships with organisations already working at the intersection of tourism and sustainability including B Corp networks, social enterprise communities, and green travel platforms

Partnership management

• Maintain a simple CRM or partnership tracker to record outreach, conversations, and active relationships
• Brief the founder regularly on pipeline and active partnerships
• Work with the Community & events marketing coordinator to ensure partner co-promotion is joined up with our own content calendar
• Identify new distribution opportunities as the event programme grows and new routes launch

Who we're looking for

Essential

• Genuine passion for sustainability, climate action, or conscious travel
• Confident communicator: comfortable reaching out cold, following up, and building relationships with people you haven't met before
• Organised and self-directed: able to manage a pipeline of outreach without close supervision
• Professional written communication skills: you'll be representing Earth Stewards externally in emails and proposals

Desirable

• Background or experience in sales, business development, account management, hospitality, or tourism
• Existing knowledge of or contacts within the London hotel, hostel, or sustainable tourism sector
• Experience with partnership or sponsorship outreach
• Familiarity with sustainable travel organisations, B Corp networks, or social enterprise communities
