Third Space Learning secures £4.4m to roll out spoken AI tutor Skye
This article covers Third Space Learning, an edtech startup, which has raised £4.4m in a growth funding round to accelerate development of its spoken AI tutor Skye and to scale its product into new subjects and languages while expanding in UK and US schools. The funding aims to convert a decade of tutoring data and research into an evidence-led push to support students and schools with one-to-one maths tutoring.
Third Space Learning, an edtech startup, has raised £4.4 million in a growth funding round to accelerate development of its spoken AI tutor Skye, scale product capabilities into new subjects and languages, and support expansion in UK and US schools. The cash injection aims to turn a decade of tutoring data and research into a tighter commercial push across two major education markets.
Why it matters
AI tools for classrooms are proliferating, but evidence of impact remains the key differentiator. Third Space Learning already operates at scale in schools, reporting support for about 196,000 students across more than 4,200 schools and delivering millions of hours of one-to-one maths tutoring. This funding will determine whether an evidence-led approach to automated tutoring can broaden its reach without losing the instructional rigour that human tutors provide.
The round also underlines growing investor appetite for edtech products that combine research partnerships with scalable delivery — a contrast to offerings that focus purely on technology or content without classroom validation.
Inside the product
Skye is a spoken AI tutor built from Third Space Learning’s decade-long tutoring practice. The product is designed around core human tutoring techniques: dialogue, pacing, targeted questioning and ongoing assessment. The company says Skye’s development is informed by the operational data and pedagogical design that underpin its one-to-one maths service.
Planned uses of the funding include technical and academic investment to improve learning outcomes, extend coverage into additional subjects and languages, and build a dedicated US function as part of international growth. The business points to a research partnership, funded with $1.9 million from the Gates Foundation and run with Stanford University and Cornell University, as evidence of its commitment to evidence-based development in US public schools.
Who are the investors?
Third Space Learning’s new equity investors include British Business Bank’s South West Investment Fund (managed by Maven Capital Partners) and Blackfinch Ventures. Existing backers Foresight Group and Nesta remain involved.
In the announcement, Rafi Khan, Investor at Maven, said:
Third Space Learning has built an impressive business, establishing the only evidence-backed, high-impact AI tutoring offering at scale, validated by partnerships with leading research institutions. Tom and his team are highly innovative with strong operational expertise in school-based tutoring. We're delighted to back the business at this point in its growth journey, and we look forward to supporting the platform as it scales.
In the announcement, Lizzy Upton, Investor at British Business Bank, said:
Third Space Learning is at the forefront of a new wave of education technology, using AI to enhance how tailored tutoring can be delivered at scale. Through the South West Investment Fund, we’re pleased to support the company’s growth as it expands its platform and reaches more learners in the UK and overseas.
In the announcement, Richard Lewis, Investor at Foresight Group, said:
Third Space Learning has a strong track record in delivering high-impact, evidence-led tutoring, underpinned by deep domain expertise. We are pleased to continue supporting the team as they build on this foundation and scale their AI tutoring platform across the UK and the US.
The investor logic is straightforward: back a company that combines classroom distribution, long-term tutoring data and academic validation. The addition of regional growth capital from a British Business Bank fund signals an interest in supporting UK-founded edtechs as they try to convert domestic traction into international revenue.

Founder perspective
In the announcement, Tom Hooper, Co-founder & CEO at Third Space Learning, said:
This investment is a significant milestone in Third Space Learning's journey. There is enormous momentum behind AI in education right now, but real impact only comes when AI tutoring is built on the same evidence and rigour as high-impact human tutoring. This funding allows us to move with greater speed and ambition - deepening Skye's capabilities, expanding into new markets, and reaching more of the students who need it most. Closing the maths achievement gap at scale is what drives everything we do, and the support of Maven, Blackfinch, Foresight Group, and Nesta brings us a meaningful step closer to that goal.
Hooper’s emphasis on evidence and outcomes reflects the company’s positioning: not just an AI product, but a tutoring service whose AI layer is intended to replicate high-impact human practices.
The bigger picture
Third Space Learning’s raise sits within a broader UK and transatlantic trend: investors are willing to fund edtech companies that combine rigorous evaluation with classroom distribution. For UK education policy and procurement teams focused on attainment recovery, tools that can demonstrate measurable learning gains will remain more attractive than flashy but untested alternatives.
As the company scales its US operations and develops Skye across more subjects and languages, the outcome will be a test of whether research-backed AI tutoring can be both effective and commercially sustainable across different school systems in the UK and US. The result will matter to educators, policymakers and edtech investors watching whether evidence-led products can translate into long-term market impact.
