We are recruiting for a Senior Venture Builder to join Nesta’s Mission Studio
Mission Studio is creating the future of mission-driven tech startups. We're tackling the UK's toughest social challenges - from net zero to obesity - by building commercially successful businesses. We have a great team of ex-founders, venture designers, builders and experienced studio operators and are looking for an exceptional senior venture builder with hands-on entrepreneurial experience to add to our team.
As a Senior Venture Builder you will partner with founders to build scalable, high-impact businesses, from concept to validation and early stage growth as well as provide guidance to other venture builders day-to-day. You will have the start-up know how, scrappiness and technical skills to transform and scale ideas into thriving businesses. These are essential to the role and to complementing our team’s existing abilities.
Please note this is a 12 month maternity cover role.
Who You Are:
Essential skills
Entrepreneurial experience: You have worked 10+ years directly at or with early-stage startups (e.g. founder, product manager, or venture studio designer/builder) and delivered strategies to progress from 0 to 1, demonstrated by a track record of launching and scaling startups or products and continually implementing lessons learnt along the way. Experience working alongside founders in a mentor style role is a plus.
Lean venture building experience: Building on the above bullet point, you have proven experience and deep understanding of Lean Startup and lean venture building methodologies, with a strong belief in hypothesis-driven experimentation, rapid MVP testing, and data-informed decision-making.
Leadership experience: Hands on experience guiding teams or individuals who are implementing building 0-1 ventures, helping to set direction, developing repeatable processes, providing counsel and challenging assumptions day-to-day.
Product development: You have experience in product management, defining roadmaps, prioritising features for early-stage ventures and user feedback / UX testing.
Growth: Experienced in driving business growth and customer acquisition, ideally through experience in a combination of the following:
Performance marketing: Running ads on Google, Meta, etc., optimising campaigns and modeling attribution
B2B marketing: testing B2B demand via lead generation
Experimentation and growth hacking: e.g. A/B testing, rapid experimentation frameworks, virality tactics, lifecycle marketing, etc.
Data & analytics: Tracking and analysis of data on user behaviour and experiments to understand user journeys and retention
Technical skills: Proficiency in tools to support support building and testing MVPs (e.g., Python, JavaScript, no-code/low-code tools) and to support marketing and user acquisition (e.g. HubSpot, Customer.io, Braze, Google analytics / Mixpanel)
Core competencies
Leadership & mentorship: You have hands-on experience leading early-stage teams and guiding others through the 0→1 journey. You set direction without ego, challenge assumptions constructively, and act as a trusted “critical friend” to help founders make better decisions.
Comfortable with ambiguity: You thrive in grey areas, look at ambiguity as an opportunity, and possess plenty of entrepreneurial grit which manifests via initiative in identifying problems and implementing solutions.
Agile & adaptable: Familiarity with rapid experimentation, A/B testing, and data-driven decision-making. You are able to iterate and pivot quickly, based on real-world learnings and customer actions.
Clear communicator: You have exceptional communication and interpersonal skills, and are able to work closely with founders, designers, and engineers to bring concepts to life and reconcile conflicting views.
Mission-driven: You're not just looking for a job; you're on a mission to make a difference, to challenge the status quo and to innovate for social good.
What You'll Do:
You will be able to hit the ground running, working across multiple concepts and with multiple founders at once to lead the testing, validation and building of venture concepts as scrappily and speedily as possible
Partner with the founders who join for the 6 month Build process working together to get the business to a strong ‘spinout’ position and ready for scale.
Be a sparring partner for founders and senior leadership team, to help them challenge the status-quo and design long-term strategies, with the goal of maximizing impact and commercial potential.
Lead product development, implementing the founder’s strategy whilst advising on best practices.
Embrace the start-up spirit, iterating fast and learning faster, all while keeping our mission at the heart of everything you design.
This is your canvas. Paint big. Be the builder behind our next-gen startups, producing solutions that are not just viable, but vital.
What we offer:
Location: At least 2 days a week at our Thames-side, Blackfriars office in London with the freedom to work remotely on other days.
Compensation: Competitive salary, between £70,000- £75,000, depending on experience
Start date and role duration: We are looking for a candidate to commence the role in late April. This is a 12 month maternity cover role.
