Pi Labs

Choosing the right route

• Pre-seed companies: the Growth Programme is the route for this stage.
• Seed to Series A companies: Direct Investment is the route, and applications are open year-round.
• Companies outside Europe: the site names Europe as its focus and does not name India. Confirm eligibility with the firm before applying.

How applications work

• The 2026 Growth Programme round is closed, and the programme page lists no later round.
• Direct Investment applications go through the form on its page, year-round.
• General questions can go to info@pilabs.vc.

How selection works

• About a quarter of Growth Programme applicants are interviewed.
• The firm says its team reviews each Direct Investment application carefully.

What the firm looks for

• Companies building a digital and sustainable built world.
• Companies with the potential to scale globally, which the Growth Programme page stresses.

Pi Labs is an early-stage venture capital firm based in London. It backs founders building a digital and sustainable built world, and it has been making investments since 2015.

How programmes work

Pi Labs has two routes. The Growth Programme is a 10-week accelerator for pre-seed companies. It pairs participants with an investment from the firm, direct introductions to prospective customers and potential investors, and an annual Demo Day. The programme is built to generate sustainable growth for early-stage companies transforming the built world. The 2026 round is closed. A hub page on the site still says "Register for interest for 2026", so the site's messages about the round do not agree.

Direct Investment is a separate route. The firm invests directly in seed to Series A companies looking to fuel their journey, and applications are open year-round. Once a founder applies, the firm says its team will review the application carefully.

Who can apply

The Growth Programme is for pre-seed companies that are early-stage and transforming the built world, with potential to scale globally. Direct Investment is for seed to Series A companies. Across the firm, the about page says it invests from pre-seed to Series A, as well as making follow-on investments.

The site describes its geographic focus in different ways. Its homepage says European and Northern American start-ups, its about page says it backs founders globally, and another page says it invests in European startups going global. The Growth Programme page also says the firm is actively investing further afield in North America, Asia and Israel. India is not named anywhere on the site. Founders based in India should confirm eligibility with the firm before applying.

Scale and track record

These are the firm's own figures, and most of them are undated.

The firm states that it has made about 100 investments since 2015 across 15 countries, over three funds, and has delivered 19 exits. It closed its third fund in 2022. The homepage counter says 90+ companies have been invested in, while another page says the firm has backed more than 70 companies. This page does not choose between those counts.

The firm's ecosystem page lists over 400 people, including founders, mentors, co-investors, limited partners and venture partners. It names more than 100 founders, more than 100 mentors, over 160 co-investors, over 60 limited partners and seven venture partners.

On the Growth Programme, the page states that 56 companies have gone through the programme to date, with no date given. It says 90% of teams have raised capital since the start of the 2022 programme. About a quarter of companies that apply are interviewed.

Location

The site gives the registered office as 33 Broadwick Street, London, W1F 0DQ. The firm is based in London. It says Europe feels like home, and that it is now actively investing further afield in North America, Asia and Israel, particularly in companies with the potential to scale globally.
