Sideby Funding (2026)
Sideby is a zero-setup co-browsing software platform built for SaaS companies, allowing customer support agents to jump into a customer's browser session, click through processes, and resolve issues in real time without requiring a separate screen-sharing tool. The company was founded in April 2021 and is headquartered in Spain, with a five-person team that includes two developers, a CEO, a CMO, and a product designer.
As of July 2021, Sideby had not yet launched commercially and was operating in pre-revenue mode, building a waitlist of approximately 300 prospective users ahead of a planned September 2021 beta launch. The company raised 200,000 dollars in seed funding, which Wilhelm Rahn, the product designer and manager interviewed by Nathan Latka, said provided roughly one year of runway given the team's Spain-based cost structure.
Sideby's seat-based pricing is set at 39 dollars per month per seat at launch, with early adopters offered a 50 percent lifetime discount bringing the price to 20 dollars per month per seat. The company was already in early-stage conversations with Dixa, a customer experience platform, as one of its first design partners.

Founder / CEO
Wilhelm Rahn
CEO
Sideby has three founders. The operating CEO is Diego, whose last name was not stated in the interview. The CMO is identified as Richelm. Wilhelm Rahn, age 35 at the time of the interview, serves as product designer and manager and describes himself as an employee rather than a founder, holding no equity in the company. Rahn said he remains open to future equity discussions with Diego.
Rahn described his background as a product designer and manager hybrid who works with companies to improve their digital products. He said the team came together out of a prior project also focused on customer success, and that Sideby represents what he views as the next step in that direction. Net worth for any founder was not discussed in the interview.

Customers
Sideby had approximately 300 people on its waitlist as of July 2021, with no paying customers at the time of the interview given the pre-launch status of the product. The company was also running 300 free trials, consistent with the waitlist figure.
Dixa, a customer experience platform described by Rahn as a competitor to Intercom, was named as an early design partner. Rahn said Sideby was in active conversations with Hugh, Dixa's chief customer experience evangelist, and that Dixa represented the type of buyer the company expects to target: heads of customer experience and customer success who understand the operational value of reducing support ticket resolution time.
Sideby's pricing is set at 39 dollars per month per seat. Early adopters who joined before mid-September 2021 were offered a 50 percent lifetime discount, bringing the effective price to 20 dollars per month per seat. The pricing model is seat-based and billed monthly. Rahn said the price point was determined through market research and direct conversations with prospective customers about what they were comfortable paying.
Sideby Business Model
Sideby operates on a seat-based subscription model, charging 39 dollars per month per seat at standard pricing. The early-adopter rate of 20 dollars per month per seat represents a 50 percent lifetime discount for customers who committed before the September 2021 launch.
The company was pre-revenue at the time of the interview. Profitability was not discussed. Rahn cited an estimated 60 percent reduction in support ticket handling time as the core value proposition the product delivers to buyers, which he described as the primary metric resonating with customer experience leaders. Gross margin, churn, LTV, CAC, and burn rate were not discussed in the interview. The 200,000 dollar raise was described as providing approximately one year of runway for the five-person Spain-based team.
