Growth Breakdown
Revenue
Sideby was pre-revenue at the time of the interview, with no paying customers yet. The team planned to launch out of beta in September 2021 at $39 per seat per month, with early adopters offered a 50% lifetime discount.
Waitlist and Early Testers
The company had around 300 people on its waitlist as of July 2021, built through Product Hunt, Reddit, LinkedIn, and Twitter outreach. Sideby was pre-launch and pre-revenue, so none of them were paying customers; the team was co-building the product with select early waitlist members to validate features before launch.
Team
The team consisted of five people total: two developers, a CEO, a CMO, and Wilhelm Rahn as product designer and manager. Three of the five were founders; Wilhelm and one developer were employees.
Funding and Runway
Sideby raised $200K in 2021 to fund operations ahead of launch. With a small team based in Spain, where the cost of living was lower, Wilhelm said that left them comfortable enough to keep running for a year or so, though the plan was to be out of beta before that.
Growth Strategy
Product Hunt Community
Product Hunt was one of the first channels the team used to drive waitlist signups and generate early awareness among the SaaS and startup community.
Cold Outreach and Community Engagement
Wilhelm and the team sent unsolicited but value-focused DMs on Twitter, left comments, and engaged in communities on Reddit and LinkedIn to attract early interest without paid advertising.
Co-Building with Early Users
The team invited select waitlist members into the product development process to co-build features, ensuring they only shipped functionality that users would actually use and avoiding unnecessary complexity.
Targeting Customer Success Leaders
The team focused outreach on heads of customer experience and customer success, who they identified as the buyers most likely to understand the value of reducing support ticket resolution time through co-browsing.

What Co-Browsing Is and Why It Matters for SaaS
Wilhelm Rahn
00:40>> We're solving it. Basically, cobrowsing has been present for a couple of years now, but it was mostly big companies, big SaaS company, or financial institutions that were using it. We're trying to take it to every SaaS company out there so they can just do that. They just they actually solve and jump in and solve every every, you know, issue their customers are having at the time.
When Sideby Was Founded
Nathan Latka
01:08How when did you start, like, designing the first pixel or writing the first line of code?
Wilhelm Rahn
01:13>> Alright. This is very surprising, but we started back in April 2021. So you are we are just coming up.
Nathan Latka
01:22Wow. Okay. Yeah. So your your site right now is beautifully designed. You're building a waitlist. How many people right now are on the waitlist?
Building the Waitlist: Size and Growth
Wilhelm Rahn
01:29>> I would say around 300, and we are rapidly growing that thanks to our CMO, which is just trying to communicate every single day.
Nathan Latka
01:40Alright, let's dive into more of this. You mentioned a CMO, you're obviously doing product design, UI, UX. What's the rest of the team? How many of you guys are there?
Team Structure and Roles
Wilhelm Rahn
01:50>> Alright. So the total team were five. We have two developers, one back, one front. We have our CEO, Diego, our CMO, Richelm,
02:03>> And mean, we are very focused. We are basically coming out from another project that was also focused on customer success. We believe this is the next step into that direction.
Nathan Latka
02:16Did the five of you guys just split equity evenly?
Equity Split and Wilhelm's Role as Employee
Wilhelm Rahn
02:20>> No. I'm an employee. There are three founders, and one of the developers are also an employee.
Nathan Latka
02:28Okay. So did you do you have equity?
Wilhelm Rahn
02:31>> I don't have equity. Well, come on, man. Why are you discussions.
Nathan Latka
02:36I was gonna say, why are you working you're young, you're handsome, you can do whatever you want, you're talented. Why are you working on something where you don't have equity?
Wilhelm Rahn
02:43>> I believe a lot in the project. I believe there's a lot to be added to that. You know, Diego is a nice guy. He's open to to to discussions. We have something in mind in the future.
Tactics for Getting the First 100 Waitlist Signups
Nathan Latka
02:58Okay. Fair enough. Fair enough. Alright. So there's 300 on the waitlist you got going in 2021. I wanna understand how you're building the waitlist because people listening right now, everyone's wondering, how do we build a waitlist? So how did you get the first 100 people on the waitlist?
Wilhelm Rahn
03:10>> Alright. So we're basically focusing on building trust, joining community, and actually providing value to them. You know, everyone in the in the team does a different thing. I normally just jump into the Twitter, try to find ways into which I can, you know, add value to people. Love Let's just try let's
Nathan Latka
03:36try and be specific. So, like, add value, blah blah blah. This is like standard. Give me real tactics. Right? So where did you find the first 100 people specifically? What community?
Wilhelm Rahn
03:45>> Alright. So first of all, product hunt. We are also going
03:55>> on Reddit. We are building a lot of community on LinkedIn. Mhmm. And a lot of perhaps the the smaller companies that we're getting, but the most eager to try it, we are getting it from Twitter. That's a combination of things. You know? I just like to, you know, engage with everybody, leave comments, send DMs with unrequested advice, but, you know, trying to to actually solve an issue. If I see an issue or something that can be
04:27>> proved on any website, I just jump ahead.
Nathan Latka
04:30So so when you Is that is that free tip?
04:34When you say you're building community, I guess I don't understand what that means. Do you run a big Slack channel with these folks, or is there a where do you guys hang out?
Co-Building the Product with Early Users
Wilhelm Rahn
04:43>> Alright. So at the moment, we are just building a hot the the waiting list. There's a couple of
04:54>> people in the community that we want to nurture. We are working together with them to co build the product. And we are inviting them into the process to actually build something that will be used in a good way. We don't want to develop any feature that's not going to be used. We don't want to, we don't want any fluff. We want to go straight to what they need.
Nathan Latka
05:18How do you incentivize these? Or I mean, there's a lot of people listening around trying to build their MVP. They'd love to actually get real customers on a Zoom call to show them design prototypes and get their feedback, but it's hard to figure out a way to actually get those people that could be interested in your tool, get on a call with you to give you that feedback. How are you doing this?
Wilhelm Rahn
05:35>> Alright. So surprisingly, we're having a, you know, not an easy time, but we are finding that people are really eager to try or at least hear about Sideby. We have a couple of surprisingly big SaaS companies that wanted to to join in the early stages.
Nathan Latka
05:52And what we Tell well, tell me the real story of one m. Name one of those companies.
Wilhelm Rahn
05:57>> Alright. So we're working in the early stages with Dixa. We we are going to be testing to them. They are a bit of a intercom acquire competitor. No. I They are I
Nathan Latka
06:17know Dixa well, so let's keep going down the funnel here. So who at Dixa knows about you guys? Who are you working with? Who are you
Wilhelm Rahn
06:23>> showing early mock ups to? Alright. So we are past the mock up stage. We are
06:34>> having this conversation with Hugh.
06:38>> He is the chief customer experience evangelist.
Nathan Latka
06:42Is that who you think you're gonna be selling to mostly, the head of customer experience, customer success?
Wilhelm Rahn
06:47>> Yes. They are the ones that really get the value of a product. They are the one that understand that, you know, cutting 60% of time on support tickets will really make a difference, lets you improve the customer satisfaction quite a bit.
Nathan Latka
07:03And how do you think that this will really take off? So, like, if I'm head of customer experience at Dixa, if I'm have a customer live chatting on my page that I can't help via text, I'm probably just inviting them to a Zoom call, and they're sharing their screen, and I'm telling them where to click and how to solve their issue. You obviously wanna replace that and say, just use, like, cobrowsing. Why is cobrowsing a better
07:22way to do customer success and support versus just getting on
Wilhelm Rahn
07:25>> a Zoom call with the person? Alright. The main thing is that we are allowing the agents to jump in, click on the stuff, and do the process. That's why, you know, either while chatting or while having a, you know, a video call. So we are not completely replacing, at the moment, any video calls. So if our customers are using screen sharing to to video call with anybody, they can also use a browsing to finish processes quickly.
Nathan Latka
07:57So you think what's gonna happen is this if if a support ticket gets escalated and they have to jump on a Zoom call, they might then use Sideby on the Zoom call so that like, if you're the customer and I am the person giving you support, I could you could share your screen and then I could actually control your screen myself on the Zoom call.
Wilhelm Rahn
08:14>> That is correct. In the case of Dixa, there's no Zoom needed because they do offer, you know, pretty well straight on the website. So we are trying to complement that for the moment, so that's why we are trying to
08:31>> do something that these big players are not doing at the moment. And we want them to use Sideby to actually do that, something that we're not doing before.
08:43>> In respect to having those video calls during cobrowsing, that's something we're working on to make it a native part of Sideby in the near future.
Nathan Latka
08:53When are you launching for, like, out of beta?
Beta Launch Timeline and Product Readiness
Wilhelm Rahn
08:57>> Out of beta, we are aiming for a September launch, but, you know, anything can change. So we are trying to release it when it's actually ready. We are just trying to make a solid product and I mean, we'll launch it when the right set of features can help the most people out there.
Nathan Latka
09:21Well, sure. But you could then be in beta for years. That doesn't work because you can't live for free. So how are you guys all paying yourselves pre revenue?
Wilhelm Rahn
09:29>> Alright, so
Funding: $200K Raised and Runway
Wilhelm Rahn
09:31>> our company raised a, first it was raising some, you know, has raised some capital, so we have a little bit of a runway to operate and focus on building products.
Nathan Latka
09:41How much did you guys raise?
Wilhelm Rahn
09:43>> Around 200 k.
Nathan Latka
09:44Got it. So how much runway does that give you?
Wilhelm Rahn
09:49>> Possibly, you know, we have a we're small team. We are based on in Spain, so the the cost of living here is not as high. So we, you know, we are in the in the comfortable spot that we could be running for a year or so, but that's not really the plan. We plan to release and get out of beta this year. You know, we don't want to extend it a lot more than that.
Nathan Latka
10:14Out of curiosity, when you guys raised the $200,000, obviously, you're pre revenue, pre product, but it sounds like really great team. What valuation are you guys able to raise out with just your team?
Wilhelm Rahn
10:24>> That's something that our CEO knows. I cannot tell you.
Pricing Strategy: $39 Per Seat Per Month
Nathan Latka
10:29Do you know?
Wilhelm Rahn
10:31>> I have a rough idea. I don't have the number in front. I have a document here with the things that I want to remember during the interview, but that exact number, I don't have it.
Nathan Latka
10:41Okay. Got it. So you guys raised $200,000 of free revenue. You're hoping to launch in September. Pricing is critical. What price point do you think you want with?
Wilhelm Rahn
10:50>> Good question. So we want to remain competitive. We know that our customers, you know, they mostly work on a a seat based pricing. Right now, what we're offering our early adopters is to have it free until mid September. And if, you know, we are offering the 50% bountiful life to join before that period. The prices we are it's just 39 US dollars per month per ticket.
Nathan Latka
11:23Per month per seat. So if they join today, they can get it for 20 per month per seat?
Wilhelm Rahn
11:28>> That's correct. Interesting.
Nathan Latka
11:29Okay. How'd you come up with that price point?
Wilhelm Rahn
11:33>> A lot of market research. We actually just straight up ask everybody what pricing that we're comfortable with, what we watch, what was the standard in the industry. And it's a price point that's good for us, we believe, will allow more SaaS companies to to access the product. We don't want to be out of range for the people we can actually help.
Competition: Surfly and the Co-Browsing Market
Nathan Latka
11:55Who are you competing with right now?
11:58What who are the big who are the people doing the best cobrowsing right now?
Wilhelm Rahn
12:02>> There's a couple of I would say the the best people in the industry would be Surfly. Definitely.

Wilhelm Rahn
12:13>> Surfly. Surflink? No. Surfly. S u r f l y.
12:18>> L a y. Surflay.

Wilhelm Rahn
12:23>> They are huge. They are pretty much the main player in the industry.
Nathan Latka
12:29How much revenue do have?
Wilhelm Rahn
12:32>> I don't have the number right now.
Nathan Latka
12:33Or you say they're huge. How do you know they're huge? What are you basing that off of?
Wilhelm Rahn
12:37>> Alright. So one of our tactics to see how the competitors are, you know, are operating and where they are operating. You know, it might sound simple, but we were just using common tools like to know which websites they were
12:56>> working on. So you can just you can just know how many installs a SaaS company have on their homepage because they crawl the web, so you can see that they
Nathan Latka
13:08So how many installs does that currently have?
Wilhelm Rahn
13:12>> I don't have number here. Sorry. No. It's big. Let me see. I I didn't know that I was going to be asked this question. Sorry. Sorry. Sorry. I will be
