  • HalalBooking

    Led · Equity · Oct 2025

    Founded in 2014, HalalBooking operates a booking marketplace that lets Muslim travelers filter more than 500,000 properties in over 100 countries for halal food, alcohol-free options, women-only facilities and modest swim policies. The company’s proprietary technology tailors search results to lifestyle requirements and has attracted a loyal base of 1.9 million Loyalty Club members across 110 countries and over 3,000 affiliate partners. In 2024 the firm is on track to generate approximately $75 million in revenue, and it logged $28.8 million in sales for the July–September 2025 quarter alone, marking 25 % year-over-year growth. Year-to-date gross booking volume reached $70 million by September 2025, while the platform facilitated more than 16,000 hotel reservations last year for over 100,000 customers. Management plans to invest in further technology upgrades, broaden property inventory and expand across Europe, the Middle East and additional high-potential regions. Looking ahead, HalalBooking intends to raise a $20–30 million institutional round in 2026 to fund its next phase of global expansion.

  • Fellos

    Participated · Equity · Oct 2025

    Founded in 2024, Fellos operates an online clinic that lets men consult a general practitioner through chat and, when appropriate, receive medication delivered directly to their homes via partner pharmacies. The platform currently targets erectile dysfunction, premature ejaculation, acne and hair loss—areas where men are often hesitant to seek in-person care. Fellos has already treated more than 10,000 patients, demonstrating rapid early traction in the Dutch market. By lowering barriers to care, the company aims to close the digital-health gap between the Netherlands and more advanced markets like the UK and Germany. With its newly secured funding, Fellos plans to expand into additional men’s health verticals and broaden its mission of making care more reliable, secure and accessible. Financially, the startup has raised over €2 million in growth capital to fuel this next phase of service expansion.
