About Fifty One Degrees
Fifty One Degrees is a London AI firm at Great Portland Street with a second office in New York, founded in 2023 according to its own about page. It is led by co-founders Nick Harding, CEO, who previously founded the consumer lender Fluro, and Mark Somers, CPO, who co-founded the risk consultancy 4most. AI is essentially the whole business: custom agents, conversational and voice AI, Claude and OpenAI enablement, a Fractional AI Officer service, and data science and engineering. Older G2 listings under the same company name describe a HubSpot marketing agency, which suggests it pivoted from growth work.
It publishes 12 case studies, 7 of them agent builds, several with figures: 48% of Heatable's aftercare inbound resolved without a ticket, monthly compliance monitoring of Phoenix's 700+ representatives, eight KYB checks per case for Equals Group. It prices its Claude rollouts on its own site, from £25,000 for Claude Ready to £50,000-£70,000 for Claude Integrated, and says a proof of concept costs under £15,000. Clutch shows 5.0 from 6 reviews, which match named case studies, and Google 5.0 from 4.
The outside record is small and recent, and four case studies give no measured outcome, including the one for 4most, a related party the firm discloses. Its Clutch reviews arrived in two bursts, its OpenAI and Claude partner listings are self-stated, and its founding year is 2024 on Clutch and DesignRush. It holds no security certification, and its two G2 listings have no reviews.

Our verdict
Fifty One Degrees suits a mid-market UK or US company, particularly in financial services, that wants a bespoke production agent or a Claude rollout at a price it can see before the first call.
The case for it is published results on named clients: Heatable resolves 48% of aftercare inbound without a ticket, Phoenix monitors all 700+ of its representatives monthly, and Equals Group runs eight KYB checks per onboarding case through an agent. Its Claude packages are priced on its own site, and its Clutch reviews describe the same projects.
The caution is age and scale. The firm is two or three years old, its outside record is 6 Clutch and 4 Google reviews collected in bursts, four of its case studies state no outcome, and one of those is for a company its own co-founder co-founded.
A small business, or a team that wants n8n or Zapier automations it can maintain itself, should look elsewhere: entry pricing starts at £25,000 for enablement and the agents are custom Python.
Pros
- Named agent case studies with figures: 48% of Heatable's aftercare inbound resolved without a ticket, 700+ Phoenix representatives monitored monthly
- Publishes Claude rollout prices on its own site, from £25,000 for 4 to 5 weeks to £50,000-£70,000 for 14 to 18 weeks
- 7 of 12 published case studies are agent builds in production or pilot
- Clutch 5.0 from 6 reviews, each matching a named case study, and Google 5.0 from 4
- Offices in London and New York
Cons
- A young firm, founded in 2023 or 2024 depending on the source, with 6 Clutch and 4 Google reviews as its whole outside record.
- Four case studies give no measured outcome, two are proofs of concept, and one, for 4most, is a related party: co-founder Mark Somers co-founded 4most, which the firm discloses.
- Entry pricing is high for a small business: Claude enablement starts at £25,000 and DesignRush lists $250 an hour.
- Agents are bespoke Python builds; a buyer who wants n8n, Make or Zapier automations to maintain in-house is outside its model.
- Its OpenAI Select Partner and Claude Services Partner status is self-stated and was not checked against the vendors' directories.
