API Startups

DID is a SaaS platform founded in 2017 by Gil Perry and co-founders Eliran Kuta and Sela Brondheim that started in privacy/face recognition protection before pivoting to an AI face platform for creating synthetic videos for media and entertainment. The company has raised $24 million, serves dozens of enterprise customers with ACVs exceeding $100,000, and recently launched with MyHeritage which generated 80 million API calls in two months. With a team of 24 (14 engineers) and strong inbound demand from PR success, DID is positioned to scale further and raise another round of funding.

Mindee is an API platform that helps software companies build document processing automation features. Founded in 2018 and launched commercially in 2019, the company serves over 70 customers primarily in financial services, charging usage-based pricing at $0.10 per page. With 15% month-over-month organic growth, 250% net dollar retention, and a $14M Series A raised in 2023, Mindee is scaling rapidly with a 27-person team (20 engineers).

Pliance.io is a SaaS platform helping regulated financial institutions comply with anti-money laundering legislation through KYC and transaction monitoring. Founded by Siam Tawdry and two co-founders in late 2018, the company bootstrapped for three years before raising a $1.5M seed round in April 2021. With 15 active customers out of 30 signed customers and current MRR of $15,000, Pliance operates on a volume-based pricing model charging approximately 50 cents per active customer screened, with their largest customer processing 250K checks monthly.

Ocale.ai is a control tower platform for operations teams managing mobile assets (delivery, ride-sharing, logistics). Founded in 2019 by Aditi Sinha and Rishabh, the company launched its product in August 2020 and has grown from ~$1,000 MRR to $40,000 MRR in one year. They've raised a $1.3M seed round and are planning to raise Series A as they approach $1M ARR with a team of 20 (11 engineers).

Spingo evolved from a DVD-based local events directory into a comprehensive event management SaaS platform. Starting with manual content curation by the founder's wife, it grew to serve 200,000+ event makers and power 5,500 entertainment apps reaching 200 million viewers monthly. The company built its SaaS product (Event Master) by recognizing that $8 billion in annual ticket sales were being driven through their platform but were undermonetized, allowing them to now focus on high-volume events (100,000+ attendees) with integrated ticketing and marketing tools.

Hurdler is a free mobile app founded in 2012 by Raj Paskar that helps independent workers (Uber drivers, Airbnb hosts, freelancers, real estate agents) manage their business finances in real time with an automated tax calculation engine. The company grew to over 100,000 users primarily through content marketing—creating high-value resources like tax deduction guides and then distributing them through community relationships. Revenue comes from value-added services like H&R Block tax filing partnerships and an API consumed by other financial institutions.

Mutiny helps B2B companies personalize their websites for each visitor to increase conversions. Founded by Jaleh Razei, a product marketer from VMware and Gusto, the company built an MVP in just 2 weeks and sold their first customer within 1-2 weeks after launch. Using a hands-on customer success approach and account-based marketing, they've grown to serve enterprise clients like Brax, Segment, Carta, and Trip Actions, with ACV between $30K-$70K and current pricing starting at $2,200/month.

Hull is a customer data platform founded by Roman Dardur that unifies fragmented customer data from multiple sources and synchronizes it across business tools in real-time. After 4 years of struggling to find product-market fit with an overly complex initial vision, Roman pivoted in late 2016 based on lunch conversation feedback, built a prototype in 5 days, and landed Mention as their first customer. Today with ~100 customers paying at least $1,000/month and $5M in funding, Hull has achieved strong PMF through word-of-mouth growth and a sophisticated IP-to-company targeting system for outreach.

Revenue Cat is a SaaS platform providing SDKs and APIs that help mobile app developers implement in-app subscriptions without building complex backend infrastructure. Founded by Jacob Eiting and Miguel in 2017, the company grew from $0 MRR with heavy reliance on content marketing (6-12 hours/week writing technical blog posts) to $400 MRR after 2 months of consistent content, then to $7K MRR by late 2018. After joining Y Combinator and raising a $1.5M seed round, Revenue Cat leveraged a smart pricing structure aligned with customer revenue growth and strong word-of-mouth to reach $161K MRR ($1.93M ARR) by July 2020, with continued month-over-month growth driven by expansion revenue and organic adoption within the developer community.

Fat Merchant is a payment technology platform founded by Sunira Madhani in 2013 that enables businesses to accept payments across multiple channels (online, in-person, invoicing) through a unified platform with transparent, subscription-based pricing. Starting with $16k MRR from white-labeled solution customers and growing to $25M+ ARR, Fat Merchant scaled through an inbound digital marketing engine and later expanded via OmniConnect API for software partners. The company has raised over $100M in venture capital and processes $5B+ annually across 7,000+ customers.

ContentStack is a headless CMS founded by Neha Sumpat that helps enterprises manage and deliver digital content across multiple channels. The company bootstrapped for the first 11 years before raising capital, reaching $1M+ ARR by 2018. After spinning out from a services company (Raw Engineering), ContentStack has since raised $169 million and grown to 450 employees across 18 countries, serving Fortune 1000 clients like Asics, Chase, and Mattel.

Ansaro was a HR-focused SaaS that aimed to use AI and data science to improve hiring and interviewing processes.
