Flat6Labs
Flat6Labs is a Cairo-based startup accelerator and seed-stage investor, one of the most active in the Middle East and Africa. As of August 2025 its investing runs through a new venture arm, F6 Ventures, under the F6 Group holding company. (don't) Waste Water tracks one water company in its portfolio, the Tunisian air-to-water startup Kumulus, across two deals.

The take
Flat6Labs has been accelerating Arab startups since 2011, when Ahmed El Alfi launched it in Cairo as the accelerator sibling of his venture firm Sawari Ventures. It is a generalist platform, not a water fund: fintech, logistics, healthtech and edtech are its bread and butter, run through seed programs in Egypt, Saudi Arabia, the UAE, Jordan, Lebanon, Tunisia and beyond. Water turns up the way it does for most generalists, as the occasional exception rather than the thesis.
Flat6Labs entered a new chapter in August 2025, folding the accelerator and a dedicated investing arm into a holding company called F6 Group. The investing now runs through F6 Ventures, a seed-stage firm managing six funds and more than $90 million, led by general partners Dina El-Shenoufy and Ramez El-Serafy, while Yehia Houry took over the accelerator. For a founder pitching the group today, F6 Ventures is the door you actually knock on.
Flat6Labs reached water through its Tunis program, not through any environmental mandate. Its single water-tracked company is Kumulus, a Tunisian climate-tech startup founded in 2021 whose machines pull drinking water straight out of the air, condensing humidity and filtering it into something safe to drink. That is decentralised drinking water for places the pipe network never reached, the kind of off-grid, development-minded bet a Middle East and Africa accelerator is well placed to make.
Flat6Labs, for a water founder, is a long shot rather than a destination: in the water raises I track it has backed exactly one water company across two deals, and it reached that company through acceleration rather than a water thesis. The open question is whether Kumulus stays a one-off or whether F6 Ventures, now hunting across Africa and the Gulf with fresh capital, decides water scarcity is too obvious a problem in its own backyard to keep leaving to others.

Frequently asked
- What does Flat6Labs invest in?
- Flat6Labs is a generalist seed-stage accelerator, not a water specialist. Through its programs and the F6 Ventures funds it backs early-stage startups in fintech, logistics, healthtech, edtech and more across the Middle East and Africa. The only water company (don't) Waste Water tracks in its portfolio is Kumulus.
- Is Flat6Labs a water investor?
- Flat6Labs is not a water fund. Water reaches it incidentally, through one portfolio company, Kumulus, a Tunisian startup whose machines make drinking water from air humidity. (don't) Waste Water tracks a single Flat6Labs water company across two deals, which places it in the occasional, not focused, water-investor category.
- What is F6 Group and F6 Ventures?
- Flat6Labs reorganised in August 2025 under a holding company, F6 Group, splitting into two arms: Flat6Labs, the accelerator now led by CEO Yehia Houry, and F6 Ventures, a seed-stage venture firm managing six funds and over $90 million. F6 Ventures is run by general partners Dina El-Shenoufy and Ramez El-Serafy.
- Who runs Flat6Labs?
- Flat6Labs was founded in 2011 by Ahmed El Alfi, with Hany Al Sonbaty as Founder and Chairman of the parent F6 Group. Today F6 Group is led by CEO Dina El-Shenoufy, who also co-founded its venture arm F6 Ventures with Ramez El-Serafy; Yehia Houry leads the Flat6Labs accelerator.
- Where is Flat6Labs based?
- Flat6Labs is headquartered in Cairo, Egypt, where Ahmed El Alfi founded it in 2011. It runs startup programs and offices across the Middle East and Africa, including Saudi Arabia, the UAE, Jordan, Lebanon, Tunisia and Nairobi. Its Tunis program is where it backed Kumulus, the one water company in its portfolio.
