About

B2B outreach is broken. You usually have two terrible choices: spend hours every day agonizing over custom DMs, or use mass automation and sound like a generic bot. That's why we built Cyranosales - your AI Ghostwriter for LinkedIn. We realized that founders, top sales pros and sales agencies are stuck in a "delegation trap." You can't outsource your inbox because a VA won't sound like you. Cyranosales solves this by capturing your exact tone of voice and drafting messages that sound like you on your absolute best day. Your only job is to be the Human Judge in the loop - just approve and done. And if you don't even want to do that, you can hand it off to a human assistant. Because your brain is best used for judging great copy, not for writing it. Cyranosales is the flagship software created and operated by our main company, Histack. At Histack, we build intelligent systems and custom B2B sales engines for scaling teams. Whether you use our plug-and-play AI (Cyranosales) or need a fully custom sales infrastructure (Histack), we help you take back your time and scale your revenue. Send me a DM, and let’s see how we can get you out of the writing seat and into the judge's chair.

Cyranosales

CEO & co-Founder

Dec 2025 – Present · 4 mos · Remote

We help founders, agencies, and sales teams scale their outreach without ever breaking character or sounding like a bot.
The Problem: You waste hours overthinking DMs to VIP prospects, but you can't outsource the work because a VA won't "sound" like you. Generic AI just sounds like an enthusiastic intern.
The Cyranosales Solution:
◼️ The AI Ghostwriter: It captures your exact tone of voice and drafts messages that sound like you on your absolute best day.
◼️ The Human Judge in the Loop: You stop writing from scratch. Your only job is to review, approve, and send.
◼️ The Ultimate Delegation: It’s so precise that you can hand your inbox over to a Virtual Assistant, knowing they will maintain the exact same quality and conversion rate as if you wrote every word yourself.
Because your brain is best used for judging great copy, not for writing it.
Cyranosales is a flagship product built and operated by Histack, Inc.

I started blink.it with my co-founder, Michael, in 2015 and transformed a "fun" idea into a company with 25 employees and a 7-digit turnover.
Bootstrapping a company from scratch provided me with extensive experience in:
Turning ideas into reality
Building a company culture of trust and growth
Selling a previously unknown product to cold leads
Self-funding the early stages of a software product with high-margin projects
Setting up all necessary departments for a SaaS company (sales, marketing, development, HR, etc.)

Stop Chasing Leads. Start Closing Deals.
At HiStack, we transform how B2B companies grow by replacing the manual "grind" of sales prospecting with intelligent, automated systems. We believe your sales team’s talent should be spent on closing revenue, not copying and pasting data.
The Problem: Most sales teams lose 40% of their week to administrative tasks—hunting for emails, managing disconnected tools, and sending generic "spray and pray" outreach that gets ignored.
The HiStack Solution: We build robust, automated sales engines using cutting-edge tools like Clay and n8n. By enriching data from over 50 sources, we help you precisely identify your ideal customers and execute personalized outreach at scale—without the burnout.
How We Help:
◼️ Done-For-You Automation: We build, run, and optimize your entire lead generation pipeline. You get qualified leads delivered directly to your CRM.
◼️ Training & Enablement: Through our 12-week intensive program, we train your internal team to master sales automation, giving you the skills to scale your own systems.
◼️ AI Catalysts: We build AI based tools improving your sales process – always with the human in mind.
From strategy and discovery to 24/7 automated lead generation, we provide the infrastructure for predictable growth.
Ready to seize the technological advantage? Let's automate your pipeline.
