Key takeaway

Forest closed £40m on 29 April with mobility VCs, £10m Fintex debt and an OKAI minority stake.

Forest closed a £40 million Series B on 29 April 2026 for London e-bike expansion⁠¹. B8 Venture Partners, Fen Ventures and Güil Mobility Ventures wrote the equity tranche; Fintex Capital provided £10 million of asset-backed debt; hardware supplier OKAI took a minority stake. The company has 1.5 million users and operates in 18 London boroughs, having recently won the sole-operator contract in Richmond.

The round translates to roughly 18 boroughs of London e-bike infrastructure backed entirely without retail-investor capital. Venture Capital Trust networks, the listed funds that channel small-investor money into early-stage UK companies, are absent from the CAP table. The VCT tax relief move from 30% to 20% in early April removed the retail seed and growth pool that once would have anchored a round of this size; growth-stage replacements are now visible.

Fintex Capital's £10m asset-backed tranche carries the structural weight. Mobility hardware spend, the bikes, batteries and docking stations, can be financed against the asset rather than from equity, which lowers founder dilution while letting Fintex secure repayment against a tangible fleet. OKAI's minority stake aligns the supplier and operator on hardware roadmap, the equivalent of a strategic investor lock-in. Specialist mobility funds writing the equity makes sense for the same reason: B8, Fen and Güil all hold mobility portfolios that benefit from co-investment exposure.

Forest's contract wins also matter. Sole-operator licences in London boroughs are fixed-term franchise instruments; lose them at renewal and the asset base evaporates. Q1 2026 brought £7.8bn into UK venture capital and that liquidity is showing up at the £40m tier. The £500k to £2m tier where most university spinouts raise has not been replaced; this is the deal shape the post-VCT-cut middle of the market produces.

Deep Analysis

In plain English

Forest is a London company that operates electric bikes you can hire by the minute via a smartphone app. Unlike the old-style Boris Bikes locked to docking stations, Forest's bikes can be left anywhere within a defined area and found via GPS. The £40m raised on 29 April will fund expansion across more of London. The money comes from a mix of sources: venture capital firms took equity stakes, a lender provided debt secured against the value of the physical bikes, and the Chinese manufacturer that makes the bikes also took a small ownership stake in the company. At 1.5 million users across 18 boroughs, Forest is already one of the largest shared micromobility operators in Britain. The new funding targets the boroughs not yet covered.

Deep Analysis

Root Causes

London's shared micromobility market consolidated faster than most European cities for two reasons.

First, Transport for London's borough-by-borough licensing system, introduced after the unlicensed dockless bike scatter of 2017-18, requires operators to demonstrate insurance, geofencing, and borough-specific parking enforcement. This compliance overhead eliminated most smaller operators by 2022, leaving a high-entry-barrier market where only well-capitalised players could compete. Forest's 18-borough coverage is itself a regulatory achievement.

Second, post-pandemic commuting patterns in London shifted toward short-distance mixed-mode trips (tube plus bike, bus plus bike) at precisely the moment when e-bike battery technology crossed the 40km range threshold that makes a zone-2-to-zone-1 commute practical on a shared bike.

Source Landscape

This story draws on neutral-leaning sources

The £40m split three ways: equity (£30m from three VCs), debt (£10m asset-backed from Fintex Capital), and hardware stake (OKAI's minority equity position). The debt-equity blend is unusual at Series B and reflects the capital-intensive nature of shared e-bike fleets: each bike costs roughly £800-£1,200, meaning 1,000 bikes requires £800,000-£1.2m in hardware capital before a single ride is taken.

OKAI's minority equity stake creates a vertically integrated supply relationship. If OKAI manufactures Forest's hardware at cost-plus, and holds equity in Forest's upside, the effective hardware subsidy functions as a product-market-fit bet. This structure is comparable to how Chinese CATL took equity positions in EV manufacturers to secure battery supply contracts at scale.

Different Perspectives

Nscale and Open Cosmos

Nscale chose the New York Stock Exchange for its listing on 18 September, putting Britain's largest AI infrastructure bet to American public investors rather than British ones. Open Cosmos took the opposite route four days earlier, raising nine figures from an all-domestic syndicate on five years of profit, evidence that staying is possible when the balance sheet allows it.

Dame Chi Onwurah and the Science, Innovation and Technology Committee

Committee chair Dame Chi Onwurah wrote to government on 7 September asking how Matt Clifford's conflict at ARIA arose and what safeguards protect its governance, and expects a detailed response. Her question has not yet been put to the Sovereign AI Unit, whose own chair sits at a venture capital firm while overseeing state AI equity.

The Entrepreneurs Network

The Entrepreneurs Network's founder survey found 65% say Britain is easy to start a business in but only 14% say it is easy to scale one, with 82% negative on tax and 74% finding investment hard to access. On this reading the constraint is regulation and tax, not the capital-vehicle design the state keeps adjusting.

New Economics Foundation

The New Economics Foundation argues fiscal accounting rules, not political will, cap what Britain's state capital vehicles can do. Matching the KfW and Bpifrance benchmark of 1% of GDP would need the National Wealth Fund to deploy roughly GBP21bn a year by 2028-29, about four times its current capacity.

Competition and Markets Authority

The CMA's 8 September report on public procurement asked whether Britain's roughly GBP400bn state-spending system is built to grow high-potential firms rather than simply widen SME participation. Its Recommendation 5 calls for a dedicated frontier-technology procurement framework, an official acknowledgement that today's design may serve the wrong target.

Highland Europe

Highland Europe, the growth-equity firm behind a €1bn-plus fund, took €65m from the British Business Bank into its Technology Growth Fund VI on 30 July via British Patient Capital. For a Geneva-based growth investor, the Bank's cheque is routine cornerstone capital, unrelated to which Whitehall department currently claims to sponsor UKRI.
