Built by
practitioners.
Accountable
in public.
The Strategic Intelligence Solutions Group (SISG) is a boutique advisory firm specialising in strategic intelligence, political and security risk, compliance, and commercial intelligence for clients operating across complex, high-stakes, and rapidly evolving environments, from competitive emerging markets to the most demanding operating conditions in the world.
Founded by practitioners with over two decades of combined experience across the MENA region and the Sahel, SISG bridges the gap between ground reality and high-level strategic counsel.
A network built
under pressure.
Our founding team has operated at the sharp end of decision-making in some of the most demanding environments in the world, across commercial, governmental, humanitarian, and security domains. That experience runs from the field to the boardroom, and it is the foundation of how we read a situation and carry it to a decision.
What sets SISG apart is not only what its founders have done. It is the network built doing it.
Across decades of engagement, we have cultivated a practitioner network of senior specialists that most firms spend years trying to assemble. These are relationships forged under pressure, with people whose judgement has been tested in the exact environments where our clients must succeed. That network is operational from day one.
SISG is headquartered in Madrid, with operational reach across the MENA region and the Sahel, extended through our associate network.
Two partners.
Neither from one discipline.
Neither answers a question from inside one discipline, which is why the firm can take a mandate that does not sit inside one either.
Zein Sourany has worked the same problem from four sides: in state service, in multilateral coordination, in humanitarian operations, and now commercially.
He has held regional responsibility across Libya, Algeria and Western Sahara, building the risk frameworks three country portfolios ran on and negotiating access directly with armed groups, tribal authorities and officials. Before that he was principal liaison in a contested sector of southern Lebanon, coordinating freedom of movement between agencies, authorities and armed actors who agreed on little else.

Complex mandates rarely fail on information. They fail on a wrong reading of who can actually deliver.

What usually takes
three firms.
SISG combines in one firm what intelligence, consulting, and compliance providers each deliver in part. Our model, and the method behind it, is set out in full.
