London-based PrimaryBid, which develops software connecting retail investors with public companies, raises €42.3M Series B

Context & Ripple Effects
PrimaryBid's €42.3M Series B lands mid-2020 as the London startup scales its core pitch: software that lets public companies allocate shares to ordinary retail investors during IPOs and follow-on raises, rather than reserving allocations entirely for institutions. The round sits inside a broader run of London fintech financings in the same period, from Modulr's €21.3M raise for digital transaction banking to Divido's lender-marketplace round.
The bet paid forward: by early 2022 PrimaryBid had converted this Series B into a $190M Series C led by SoftBank's Vision Fund 2, confirming that issuer-side demand for retail inclusion was durable enough to attract top-tier growth capital.
First-order effects
- PrimaryBid gains the capital to scale its placement software across more public companies and offerings, moving retail allocation from pilot deals toward a standard part of its bookbuilding product.
Second-order effects
- Investment banks and issuers running UK fundraises face growing pressure to include a retail tranche, since a rival platform now has the funding to make retail participation operationally routine.
Third-order effects
- If the SoftBank-backed follow-on is any guide, retail-inclusion infrastructure consolidates into a category of its own within capital markets plumbing, with London as the proving ground for whether ordinary investors get structural access to primary issuance.
The trend: Capital markets are slowly rewiring share allocation so retail investors participate directly in primary issuance, and London fintech is where that infrastructure is being funded first.
