Top Startup Agencies of 2023: A Comprehensive Review

In the rapidly evolving world of startups, having the right agency by your side can make all the difference. As we navigate through 2023, we've seen a plethora of agencies emerge and grow, each offering unique services and expertise to help startups succeed. Today, we’ll take a closer look at four agencies that stand above the crowd: Stackmatix, Manifiesto, Studiohelm, and Salesbullpen. We’ll analyze their benefits and rank them based on their offerings and capabilities.



1. Stackmatix

Stackmatix is naturally our top choice for startup partners in 2023. We provide a comprehensive range of services, including SEO, advertising, organic social media, creative, and advising services. We also move quickly, getting clients up and running at a speed most other agencies can’t match, and drive those results that much faster.

What Makes Us Different:

  • Full suite of digital marketing services: Stackmatix offers a one-stop solution for startups looking to improve their online presence and drive growth.
  • Expertise in multiple industries: Stackmatix has a diverse portfolio that showcases their ability to work with startups in various sectors.

  • Personalized advising services: Stackmatix goes beyond just marketing, providing tailored guidance to help startups navigate the complexities of scaling and growth.

2. Manifiesto

Manifiesto is a branding-specialized design studio that helps startups create a strong visual identity and brand presence. They believe that ideas have the power to transform, and they’ve translated this core belief into a business that turns unique ideas into memorable concepts, images, spaces and experiences.

What Makes Them Different:

  • Branding expertise: Manifiesto's primary focus on branding ensures that they have the skills and knowledge to create memorable and impactful brands.
  • Creative team: Manifiesto is known for its talented designers who can bring innovative ideas to life. Their expertise includes art direction, motion graphics, branding, illustration, and more.
  • Customized solutions: Manifiesto works closely with startups to develop unique branding strategies that resonate with their target audience.

However, as a branding-specialized agency, Manifiesto may not cover all the marketing needs of a growing startup, such as advertising or SEO. Startups might need to engage other agencies for services outside of branding, such as digital marketing or SEO. We recommend Manifiesto for startups specifically seeking brilliant branding assistance.

3. Studiohelm

Similarly to Manifiesto, Studiohelm is a creative agency that offers design, branding, and marketing services to startups. Specifically, they specialize in branding, digital & print.

What Makes Them Different:

  • Versatile service offerings: Studiohelm provides a mix of design, branding, and marketing services, catering to various startup needs.
  • Collaborative approach: Studiohelm works closely with clients to ensure their vision is accurately translated into the final product.

Like Manifiesto, Studiohelm's focus in creative branding may result in less specialized expertise in specific areas, such as SEO or advertising.

4. Sales Bullpen

Sales Bullpen is an agency focused on helping startups build and scale their sales teams and processes. They assess your current sales efforts, help build KPIs, process, and strategy, & grow your business.

What Makes Them Different:

  • Sales expertise: Salesbullpen specializes in sales strategy, making them an excellent choice for startups looking to ramp up their sales efforts.
  • Scalable solutions: Salesbullpen offers solutions that can grow with a startup, ensuring a seamless transition as the company expands.

While Salesbullpen is a great choice for startups focused on sales and developing out those teams, they do not offer the full suite of services a startup might need to propel their growth. To supplement growth, startups may need to contract another agency focused on other needs like branding or advertising.

5. Default

Default is a product engineering firm focussed on working with early-stage startups. The founders have a history of successful exits and understand the engineering needs of an early stage startup. What makes them different:  

What Makes Them Different:

  • Build operate transfer model, which allows startups to build the first version of the product with them and then they help you hire the right team to carry it forward.
  • They can also help with setting up engineering, tech hiring and product development processes
  • Their understanding of how to balance between cost, quality and time pre-product market fit

6. IncubateHR

IncubateHR cultivates scalable HR solutions that feel organic to your organization and its unique company culture.

What Makes Them Different:

  • Our services are perfect for fast-growing companies and small businesses who aren't ready for a full time HR team, but would like to implement HR best practices.  We do the work so you don't have to.
  • We do not implement boilerplate HR solutions - you'll get custom end-to-end people frameworks that are tailored to your organization's specific needs.
  • With our retainer model you'll have access to a personable HR expert to support you and your team 1:1, whenever you need.  

7. is an award-winning product and software development company committed to helping entrepreneurs and business leaders worldwide build high-quality, user-centric products.

What makes them different:

  • Formed by ex-startup founders, they know how to bring new innovative products to market. The startup ecosystem is in their DNA.
  • At their core, they design and build high-quality, user-centric software products for entrepreneurs and business leaders, but their entrepreneurial experience also allows them to add extra layers of value. They’re closer to an extended team of co-founders than a supplier - often referred to as such by their clients.
  • They have an enviable track record of helping two-thirds of their clients build products that achieve VC funding in an ecosystem where only ~0.05% of startups ever see that landmark.

Altar’s lean mindset, frameworks and ability to execute ensure that the software products they build severely increase the odds of success for any venture.
