Mentoring for Early-Stage B2B/B2C Tech and SaaS Founders

Building was easy. Nobody warned you about the silence afterwards.


You started this because you saw something that hadn’t been built. You knew you could build it. You did build it. The architecture is clean. The MVP works. The few people you’ve shown it to said it was “really cool.” One of them paid you, sort of, after a discount.

Six months in. Maybe twelve. You’ve added three more features because you weren’t sure what was missing. You’re not sure those features were the answer either.

The product is solid. The market has gone quiet.

That quiet is the loudest thing in your week.


I’m Sid Kathirvel, founder of Unlock Growth. I’m a trusted mentor through CodeBase Techscaler, Barclays Eagle Labs, Opportunity North East, and Edinburgh Innovations. I work with early-stage businesses across Edinburgh, the Lothians, Glasgow, Aberdeen, and throughout Scotland.

You wrote the cold email. You didn’t send it. You went back to the code.


You spend most of your week inside the product. You tell yourself you’re shipping — and you are, technically. There’s a feature you can polish. An onboarding flow you can rework. A bug that a beta user mentioned three weeks ago that’s been sitting in your head.

You spend three days on it. It feels like progress because you’re moving.

Underneath, you know you’re hiding. Building is the part you know how to do. The other part (talking to strangers about money, writing the cold email, standing on a stage, recording the demo video) wasn’t in the original plan.

You wrote the cold email last Tuesday. You rewrote it on Wednesday. By Thursday, you’d softened it, hardened it, and softened it again. You finally sent it on Friday. Nobody replied. You’re not sure if it’s the email that’s wrong, or the list, or you. You’re not sure how to find out. Sending the next one feels like flinching.

Some part of you secretly suspects the product is still just a hypothesis. That, when an enterprise prospect actually puts it through real conditions, it’ll fall over. That, when someone asks “so how does this compare to [the big incumbent]“, you’ll hesitate just long enough that they’ll notice. You’ve already had calls where you suspect the buyer sensed your insecurity — they suggested “let’s chat, see how it goes,” and you went along with it because resisting felt like overclaiming. That deal hasn’t moved since.

If there’s a co-founder, the conversations with them have become circular. Same topics. Same dead ends. The problem keeps getting kicked down the road because neither of you knows where to start, and admitting that to each other feels like admitting too much.

If there’s no co-founder, the isolation is its own particular thing. You’re doing the code, the partnerships, the customer support, the demo calls, the pitch deck, the financial model, and the contractor invoices. Nobody is in the boat with you. The only way you’d know whether you’re doing any of it well is if someone outside told you. And there’s nobody outside who’d know.

You watch competitors with worse products win bigger deals. Their marketing is slicker. Their LinkedIn presence is louder. Their websites talk about outcomes while yours talks about features and integrations — because that’s what you’ve actually built and that’s the part you’re proud of.

You catch yourself thinking: they shouldn’t be winning. We have a better product.

And then immediately: but we’re the geeks in the garage. They have a sales team. We have a Stripe account and a pipeline that won’t fill.

To keep the trickle of conversations alive, you’ve started offering free trials. Or extended free trials. Or “just pay what feels fair, we’ll figure it out later.” The first time you discounted, it felt like a strategic move. The third time, it started to feel like begging. The handful of users you do have are getting white-glove onboarding from you personally (calls, screen-shares, custom Loom videos) because you’re terrified that if anything fails for them, you’ll lose the only social proof you have. Those hours of hand-holding per user doesn’t scale, and you know it.

Underneath all of it is the financial runway. Twelve months. Nine. Six. The number gets smaller every Sunday night when you do the maths. Every month that goes past without traction is a month you can’t get back. Every feature you ship instead of doing customer interviews is a small bet that the next thing you build will finally be the thing that makes them care.

You don’t know if any of those bets are working. You can’t tell from the inside.

Sid was a really helpful sounding board in the run-up to Scottish EDGE. He helped me refine the emotional storytelling behind BlazeBalm™ and shared really useful marketing frameworks that went well beyond the pitch training. Sid had a genuinely holistic understanding of what I was trying to achieve, offered insight beyond the immediate competition, and asked probing questions that helped me sharpen my delivery.

We went on to win and secure the amount of funding we’d been hoping for. But the benefit extended beyond that and will help drive BlazeBalm™ forward.

Dr. Alisha Fuller-Armah, Inventor + Founder, Draconite™

Building Vero, we’d been stuck on growth for some time, and Sid gave us incredibly valuable guidance and advice. He was very well-structured in the way he approached marketing and helped us go back to the fundamentals to really uncover and refine our core message.

What stood out most was how Sid used relatable real-world examples and broke down frameworks in a way that was easy for us to understand and apply within our own context. The session gave us a lot of clarity, practical direction, and genuinely useful food for thought moving forward.

Supharat Tantanarungsee, Co-Founder, Vero Financial

Sid radically shifted my perspective, helping me see my product through the eyes of a potential buyer. He’s an exceptional listener, incredibly generous with fresh ideas and practical suggestions, and has been an invaluable guide throughout the entire process, from refining our marketing strategy to landing our first client.

None of this is a product problem


It’s a market-message-fit problem dressed up as a product problem, which is dressed up as a confidence problem.

I can say that because I’ve spent 25 years watching it happen: across advertising, technology, and growth marketing, across industries most consultants have never worked in, and, painfully, including my own businesses earlier in my career, where I should have known better. That accumulation is what lets me spot the pattern quickly, whatever shape it’s wearing when you walk in.

I’ve sat across from more than 140 founders in mentoring conversations. The product designer’s hiding place, staying in the code instead of getting out into the market, is the single most expensive mistake early-stage tech founders make. I’ve made it. Almost every founder I work with has made it. Nobody escapes the gravitational pull of the work they’re already good at.

Here’s what becomes visible the moment someone with the right framework sits down with the actual specifics of your product and your buyers.

There’s a job your earliest, best users were trying to get done when they reached for something like you — and it’s almost certainly not what your product page currently says. There’s a Locksmith Moment, a trigger that gets a buyer from passive interest to actively looking for a fix, and that moment has nameable specifics, even if your category feels too new for it. There are Four Forces working on every single one of those buyers: the push of their current pain, the pull of your promise, the anxiety holding them back, and the habit keeping them where they are. The ones blocking your deals are usually anxieties you’ve never named, not features you haven’t shipped. And there’s a wedge, a specific contrarian position only your product, your founder story, and your way of building can credibly own, that you’ve never written down because you’ve been too close to it to see.

When even part of that becomes clear, the next outreach email stops feeling like flinching. The pricing conversation takes on a different shape. The features you choose to ship next change. The white-glove onboarding starts looking like a temporary acceptable cost rather than a permanent business model. The runway maths gets a different denominator.

You don’t need to learn marketing.

You need to stop building for a moment, sit down with someone who can ask the questions you’ve been avoiding, and see what’s already there in the work you’ve already done.

I truly appreciate the clarity and direction Sid provided. Sid’s recommendations have given me a stronger sense of focus as I continue building Shop Much More. The ongoing support from both Sid and the CodeBase team has played a big role in helping me reach this stage, and I’m genuinely grateful.

Samuel Johnson, Founder, Shop Much More

Sid was really great at extracting the right bits of information from us in order to work out how to best present key benefits for our customers. It was a great workshop that helped us start framing the initial bits of positioning for our first launch.

Ana Betancourt, CEO, Black Goblin

I truly appreciate the clarity and actionable advice that Sid provided. Sid has given me a lot to think about and a clear direction for next steps.

The first hour is £99

You’ll walk away with three things.


A Jobs-to-Be-Done reading of the buyers you’re actually trying to reach, in language they would recognise, not the language on your product page right now. The distinction between what you think you’re selling and what they’re actually trying to buy is usually where the whole thing unlocks.

One Locksmith Moment named: the trigger that takes your ideal buyer from passive interest to actively looking, and where your product needs to be visible at that exact instant. Most early-stage products are positioned for the wrong moment entirely. Naming yours changes what you build next, and what you say about what you’ve already built.

A homework experiment, usually one specific customer conversation that’s worth more than a month of feature shipping, that you can run before any next conversation we ever have.


Whether we ever speak again is up to you. The hour stands on its own.

Most of the early-stage founders I do these with say it was the most useful hour they’d spent on the business, not the product, in months. Some stop there. Some come back when they hit the next wall, usually around pricing, or the first real go-to-market push, or the moment they realise the white-glove onboarding has eaten the quarter. Some want a fortnightly slot, real homework between sessions, a partner who’ll actually remember what you said three weeks ago and ask whether you ran the experiment. All three are fine. The first hour is where we figure out which fits you.

If we do continue, the same bank-of-hours model that runs through all my client work applies: £245 an hour as standard, from £145 an hour on banked-hour packages, no retainer, no lock-in, unused hours refunded. Full rates and what packages look like →

Sid was so helpful in helping us identify where to sharpen our messaging and how to convey our mission to our audience.

Jon Hudson, Co-Founder, TEAL (Teachers’ Empowerment and Advocacy League)

Sid was able to understand our product and listened to the challenges that we were facing. He highlighted key gaps and helped structure a clear path to move forward. Real value.

Simon Santamaria, Co-Founder, Emberon Tech

Sid really took the time to understand our current problems and helped us plan what to focus on. He also shared materials. Highly recommend!

£99. One hour. Book directly in my calendar.

If you’ve read this far and recognised more than a few of these moments, that’s probably your answer. The next right move is to book the first hour and find out whether working together longer would help. You’ll pick a time directly from my availability, pay the £99 via Stripe, and fill in a short form covering your business, your customers, your team, and the challenge you’re carrying. That’s what lets me show up useful from minute one rather than spending the first twenty minutes getting up to speed.

A couple of practical things worth knowing. You can reschedule up to 24 hours before the session at no charge. Changes inside 24 hours and no-shows aren’t refundable. The £99 rate applies to the first session only — if we decide to continue, you’ll move onto one of the standard or preferential hour packages, purchased upfront. Full rates and packages →

You’ll leave that hour with something useful regardless of what happens next. That’s the contract.

Thank you once again, Sid, for sharing your experience with us! It’s by far one of the best marketing sessions I’ve ever attended, and I’ve attended over a dozen of them over the years!

Anton Puzorjov, Founder and CEO, Quas Drinks

It’s quite difficult to find someone who can provide a structured and clear pathway to marketing a product. Feeling overwhelmed by the sheer number of possible marketing directions, we initially came in expecting surface-level advice. Instead, we left with a much deeper understanding of how we should think about our brand messaging before even attempting to sell the product.

Sofia Sukach, Co-Founder @ Vero Financial

The session was honestly such a game-changer! It was packed with practical advice and real, eye-opening moments that every founder or entrepreneur can relate to. Sometimes, building a business or product can feel overwhelming, but sessions like this make you realise you’re not alone and give you the tools and confidence to keep going. Huge thanks to Sid Kathirvel for your engaging presentation style and the energy you brought to the session, and Techscaler for making this possible. If you get the chance, definitely check one out. You’ll walk away feeling inspired and ready to take on the next challenge.
