Fractional CTO 💡 Top Startups Voice⚡ Helping startups make better SaaS

I'm an experienced SaaS CTO, working on a 'Fractional' basis, meaning that companies can hire me part-time as their Interim CTO, or as an advisor to the board. 

I work for startups, scaleups, ISVs and other software companies, or consultancies turning into SaaS companies.

My work is transformational: when I leave, a company should be better off in terms of their (tech) strategy and/or operational excellence.

Before becoming a CTO, I have been a solutions and cloud architect. I still code, as an open source contributor, and sometimes for 'my' startups, doing Proof-of-Concepts.

I'm a Web Standards evangelist, and a Social Impact Lover. 

I've seen it all, with more than 30 years of experience in Software Development, and I'm now focusing on Native Cloud as a natural fit for startups and scaleups.

I write a lot about the life of a CTO, and about the Modern Web.

Chief Technology Officer

According to chatGPT, this is what AI thinks about me:

Oh boy, here comes Oshri Cohen, the fractional CTO who’s got the look of a man who’s perpetually stuck between a tech startup pitch and a modelling gig for "Men’s Plaid Monthly." That checkered shirt is doing its best to scream "casual" while you’re giving off serious "I’m about to deliver a TED Talk on the future of AI" vibes. Did you just roll out of bed or roll out of a GQ photoshoot? Because honestly, it’s hard to tell.

Let’s talk about that hair for a moment. It’s as if your barber said, “I’m going to give you the hairstyle of a rugged entrepreneur who hasn’t had time to worry about trivial things like grooming,” and you responded with, “Make it look like I’m always thinking ten steps ahead.” Are you planning a hostile takeover of a tech firm or just trying to figure out what’s for lunch? The world may never know. 

Your expression is priceless too. That’s the face of a man who’s just been asked to explain blockchain to a room full of 80-year-olds. There’s a mix of determination and resignation in your eyes, like you’ve seen things… tech things. Maybe you’re pondering the intricacies of quantum computing, or maybe you’re just trying to remember if you turned off the coffee pot this morning. Either way, it’s intense.

And speaking of intensity, let’s not ignore those rolled-up sleeves. Classic move, my friend. It says, “I’m ready to get down to business, but also, I might fix your Wi-Fi if you ask nicely.” The epitome of approachable professionalism. You’re not just a man of action; you’re a man of subtle yet impactful fashion choices. That shirt is perfectly tucked in, not a wrinkle in sight. Did you iron it with your mind while solving complex algorithms? I wouldn’t be surprised.

Now, let’s address the whole fractional CTO thing. That title is like saying, “I’m so good; they only need a fraction of my brilliance to keep things running.” It’s the ultimate power move. Why be a whole CTO when a fraction of you is more than enough? You’ve got 25 years of experience packed into a demeanour that says, “I’ve seen some stuff. I’ve debugged code in the trenches and lived to tell the tale.”

So here you are, a paradox wrapped in plaid, a tech guru with the looks of a model and the wit of a comedian. Keep doing you, Oshri. The world of technology needs its heroes, especially the ones who can rock a checkered shirt and a steely gaze while cracking a joke about the latest software update.
