B2B Case Studies
You don't need a better pitch.
You need better proof.
Prospects don't stall because your offer's weak, they stall because they can't tell if they can trust you to deliver. Social proof fixes that.
We turn one chat with your happiest customer into a complete B2B case study, including video, written, and a social pack.
You're losing deals you should be winning.
Not because your product's worse. Not because your pitch is weak. But because when you say you're good, you're not giving them a reason to believe you.
That's the trap. Everything you say about you gets viewed through a sceptical lens. You're the seller, of course you think you're great. The issue isn't how you're saying it, the problem is that promises aren't enough.
Promises only work if they're supported with facts. A real customer, on the record, backing up everything you promise. That's not a pitch. That's proof.
Ring a bell?
- Prospects go quiet right after a good sales call
- Your only "proof" is a logo wall
- You've got a customer who'd rave about you, but nobody's asked them yet
- Sales can't back up what they say
- You've been meaning to get a case study made for over a year
If any of these sound familiar, you need proof to help you get deals over the line.

How LeadForce Solutions found SaaS leads that don't exist in other databases with SaasyDB
LeadForce Solutions, a go-to-market engineering firm for AI and software companies, needed a lead source with contacts that weren't already saturated with outreach from competing agencies. Founder Aaron Gusinov discovered SaasyDB through a recommendation from go-to-market practitioner Taylor Heron, tested the data with a monthly subscription, and found that most contacts did not appear in any other database he checked. When scored against his target persona criteria, the majority of SaasyDB leads landed in "perfect fit" or "good fit" — a hit rate he had not seen from broader platforms. Aaron purchased a lifetime deal for $1,500, calling it his best investment in lead sourcing. Cold email campaigns using SaasyDB leads produce a 3% overall reply rate with 10–15% positive responses.
What problem was LeadForce Solutions trying to solve?
Aaron Gusinov designs, builds, and runs outbound systems in-house for AI and software companies looking to grow. His own client acquisition runs on the same cold email infrastructure he builds for others. If the lead source is weak, his pipeline dries up.
What was the hidden cost of an unreliable lead source?
Beyond the filtering problem, Aaron describes a "mental cost" in not knowing whether the leads in his database were current, relevant to his niche, or already receiving dozens of competing pitches each week. For someone whose business depends on standing out in an inbox, that doubt hung over every campaign. "If they're already in a public database that everyone has access to, you are competing, even if your offer is amazing, by virtue of having 50 other offers that are not good."
How did Aaron discover SaasyDB?
While building LeadForce Solutions alongside a position at J.P. Morgan, Aaron was studying go-to-market engineering from practitioners who had already built outbound agencies. One of them was Taylor Heron, a prominent figure in the field.

How Mila added 4,000+ LinkedIn connections in 2.5 years with Extrovert
Mila Tsirelman sells technology services for COMMIT, a firm with 1,200+ enterprise clients across AI, cloud, and cybersecurity. After adopting Extrovert's AI-powered engagement platform, she grew her personal network from roughly 5,000 to over 9,000 connections in 2.5 years, with the majority of new connections driven by 10–15 inbound requests daily from target-audience prospects who discovered her through AI-assisted comments. Her team adopted the platform 1.5 years into her own use. She now runs two Extrovert accounts daily, crediting the tool with shortening her sales cycles by converting cold outreach into warm inbound conversations.
Why wasn't LinkedIn working for Mila before Extrovert?
Mila Tsirelman manages business development across EMEA for COMMIT, a technology services firm that builds software, AI/ML solutions, cloud infrastructure, and cybersecurity products for more than 1,200 enterprise clients. Her job is finding and closing new business. LinkedIn? Before Extrovert, she barely used it.
What changed in the first three months?
Mila started using Extrovert 2.5 years ago, initially on her own before her team joined 1.5 years later. The early weeks weren't easy. The biggest pitfall was targeting — LinkedIn's most active commenters tend to be students and early-career professionals, not the enterprise buyers she was after. She refined her playbook three to four times before the tool started surfacing the right people consistently.
How does Extrovert surface prospects Mila would never have found?
Ask Mila what she values most about Extrovert and she won't say the AI commenting. It's the content discovery underneath. The platform surfaces posts from people she has no connection with, matched by topic rather than who she already knows.

Book a callThese folks trust me.
Best Case Studio is a brand new company, so we don't have many testimonials yet. But I was a freelance copywriter for eight years before this. Here are a few things past clients have kindly said about me.
In just two days, we completely rewrote Creatora.io's homepage. Same product, same features, but a radically clearer story. He didn't just improve our messaging. He saved us weeks of wandering in the dark.
Jon's feedback on how to improve the positioning of my SaaS company was powerful, easy to digest, and easy to implement. I'd recommend Jon to anyone whose marketing website is important to their company's growth.
Jon's an extremely talented writer, professional and scrupulous to the highest degree. We've used him on a lot of content projects and we're looking to use him even more. Don't hesitate — he won't let you down.
His ability to create original and engaging content on any topic has made him the go-to writer at Powered By Search. Bouncing ideas and structuring content strategies with him is super easy.
He brought fresh perspectives we'd never thought of and gave us a new tone of voice that's more vibrant — but the essence of our value is still very clear. That's skill.
Who's actually doing this.
Best Case Studio is a two-person, husband-and-wife studio. Jon runs every interview personally — that part is never delegated.

Frequently asked questions.
Everything you need to know before sending us a case study.
Do I have to ask my customer for a favour?
No. You make one warm intro. That's it. We handle the ask, the scheduling, and the interview, and we make it effortless for them. Nobody's grovelling.
What if my results are confidential or under NDA?
We can anonymise. A skilled interview pulls out the value of the story without exposing anything you can't share.
I got burned by a cheap case study before.
Yeah, we hear that a lot. Cheap-and-generic is exactly what we exist to fix. Go read an example and judge for yourself. That's the whole point of showing them.
SaaS or services? Who's this for?
Both. If you sell B2B and you've got at least one customer who's genuinely happy, you've got a Proof Kit waiting to be made. If you're pre-product-market-fit or your customers wouldn't publicly endorse you, this isn't your next move yet.
What if my customer says no?
Rare, when the intro's warm and we make it easy. But if they pass, we'll build the kit around your next-best customer. You're not paying for a maybe.
Who actually does the work?
Jon McGreevy runs every single interview — that never gets handed off. As we grow we may bring in trusted help on writing or editing, but the conversation with your customer is always Jon's. Jessie McGreevy handles scheduling and project logistics.
Do you work with clients outside the UK?
Yes. Most of our clients are in North America. Interviews are remote, pricing is in USD, and we work to your timezone for calls.
Your move.
Your best customer already said the thing that closes your next deal.
You just haven't captured it yet. One intro. One conversation. A complete Proof Kit in two weeks — for $2,500.
Or send us a case study you've already got and we'll tell you, free, what's letting it down. Email Jon →
